{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are reclined like this.
The shoulder belt cannot do its job because it
will not be against your body. Instead, it will be
in front of you. In a crash, you could go into it,
receiving neck or other injuries.
The lap belt cannot do its job either. In a
crash, the belt could go up over your
abdomen. The belt forces would be there, not
at your pelvic bones. This could cause serious
internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.
Do not have a seatback reclined if your vehicle
is moving.

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Do not let anyone ride where he or she cannot
wear a safety belt properly. If you are in a
crash and you are not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers’ belts are
fastened properly too.
5. Push the pin with the gray cap marked “L” down
until it is in the retaining clip.
6. If the vehicle has a floor mat, put the flap back to
its original position.
7. Repeat this procedure for the other seat base.
8. Connect the quick-release latch plates for the
lap-shoulder belts by inserting the latch plates
into the buckles attached at the outboard positions
of the bench seat. Do not twist the belt.
9. Check that all locking pins are locked into place
before operating the vehicle.

After more than 30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter...a lot!
{CAUTION:
Why Safety Belts Work
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
When you ride in or on anything, you go as fast
as it goes.
Your vehicle has indicators to remind you and your
passengers to buckle your safety belts. See Safety Belt
In most states and in all Canadian provinces, the law
says to wear safety belts. Here is why: They work.
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person would not
survive. But most crashes are in between. In many of
them, people who buckle up can survive and sometimes
walk away. Without belts they could have been badly
hurt or killed.
Take the simplest vehicle. Suppose it is just a seat
on wheels.

Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicle after an accident
if I am wearing a safety belt?
A: You could be — whether you are wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you are upside down. And your chance of
being conscious during and after an accident,
so you can unbuckle and get out, is much greater if
you are belted.
Q: If my vehicle has airbags, why should I have to
wear safety belts?
A: Airbags are in many vehicles today and will be in
most of them in the future. But they are
or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That is why
safety belts make such good sense.
supplemental systems only; so they work with
safety belts — not instead of them. Every airbag
system ever offered for sale has required the use of
safety belts. Even if you are in a vehicle that has
airbags, you still have to buckle up to get the most
protection. That is true not only in frontal collisions,
but especially in side and other collisions.

Driver Position
Q: If I am a good driver, and I never drive far from
home, why should I wear safety belts?
Lap-Shoulder Belt
A: You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not protect you from things beyond your
control, such as bad drivers.
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than 40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be

4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, see Safety Belt
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
5. Move the shoulder belt height adjuster to the height
that is right for you. See Shoulder Belt Height
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you would
be less likely to slide under the lap belt. If you slid
under it, the belt would apply force at your abdomen.
This could cause serious or even fatal injuries. The
shoulder belt should go over the shoulder and across
the chest. These parts of the body are best able to take
belt restraining forces.
6. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
The safety belt locks if there is a sudden stop or crash.

Shoulder Belt Height Adjustment
Before you begin to drive, move the shoulder belt
height adjuster to the height that is right for you.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should
be away from your face and neck, but not falling off
your shoulder.
To move it down, pull on
the center adjuster control
labeled PULL. You can
move the height adjuster
up just by pushing up
on the shoulder belt guide.
To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage
both the belt and your vehicle.
After you move the height adjuster to where you want it,
try to move it down without pushing in to make sure it
has locked into position.

Safety Belt Pretensioners
Safety Belt Extender
Your vehicle has safety belt pretensioners for the driver
and right front passenger. Although you cannot see
them, they are located on the buckle end of the safety
belts. They help the safety belts reduce a person’s
forward movement in a moderate to severe frontal and
near frontal crash.
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt is not long enough, your dealer will
order you an extender. It is free. When you go in to
order it, take the heaviest coat you will wear, so
the extender will be long enough for you. To help avoid
personal injury, do not let someone else use it, and
use it only for the seat it is made to fit. The extender has
been designed for adults. Never use it for securing
child seats. To wear it, just attach it to the regular safety
belt. For more information, see the instruction sheet
that comes with the extender.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. See Replacing

Q: What is the proper way to wear safety belts?
Child Restraints
A: If possible, an older child should wear a
lap-shoulder belt and get the additional restraint a
shoulder belt can provide. The shoulder belt
should not cross the face or neck. The lap belt
should fit snugly below the hips, just touching the
top of the thighs. It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in a crash.
Older Children
Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.
Older children who have outgrown booster seats should
wear the vehicle’s safety belts.
If you have the choice, a child should sit in a seating
position that has a lap-shoulder belt to get the additional
restraint a shoulder belt can provide.

Q: What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A: If the child is seated in a rear outside seat position,
move the child toward the center of the vehicle. Also
If the child is sitting in the second row center seat
position, move the child toward the safety belt
buckle. In either case, be sure that the shoulder belt
still is on the child’s shoulder, so that in a crash the
child’s upper body would have the restraint that belts
provide. If the child is so small that the shoulder belt
is still very close to the child’s face or neck, you
might want to place the child in a seat that has a lap
belt, if your vehicle has one.
{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.

Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the belt in
this way, in a crash the child might slide under
the belt. The belt’s force would then be applied
right on the child’s abdomen. That could cause
serious or fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just touching
the child’s thighs. This applies belt force to the child’s
pelvic bones in a crash.

Infants and Young Children
{CAUTION:
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
People should never hold a baby in their arms
while riding in a vehicle. A baby does not
weigh much — until a crash. During a crash a
baby will become so heavy it is not possible to
hold it. For example, in a crash at only 25 mph
(40 km/h), a 12 lb (5.5 kg) baby will suddenly
become a 240 lb (110 kg) force on a person’s
arms. A baby should be secured in an
appropriate restraint.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle’s
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.

Q: What are the different types of add-on child
restraints?
A: Add-on child restraints, which are purchased by the
vehicle’s owner, are available in four basic types.
Selection of a particular restraint should take
into consideration not only the child’s weight, height
and age but also whether or not the restraint will
be compatible with the motor vehicle in which it will
be used.
For most basic types of child restraints, there are
many different models available. When purchasing a
child restraint, be sure it is designed to be used
in a motor vehicle. If it is, the restraint will have a
label saying that it meets federal motor vehicle
safety standards.
{CAUTION:
The restraint manufacturer’s instructions that come
with the restraint, state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
Children who are up against, or very close to,
any airbag when it inflates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer protection for adults and older
children, but not for young children and
infants. Neither the vehicle’s safety belt system
nor its airbag system is designed for them.
Young children and infants need the protection
that a child restraint system can provide.

{CAUTION:
{CAUTION:
Newborn infants need complete support,
including support for the head and neck. This is
necessary because a newborn infant’s neck is
weak and its head weighs so much compared
with the rest of its body. In a crash, an infant in a
rear-facing seat settles into the restraint, so the
crash forces can be distributed across the
strongest part of an infant’s body, the back and
shoulders. Infants always should be secured in
appropriate infant restraints.
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.

Child Restraint Systems
A rear-facing infant seat (B) provides restraint with the
seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous flat
surface. Make sure that the infant’s head rests toward
the center of the vehicle.

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.
A booster seat (F-G) is a child restraint designed to
improve the fit of the vehicle’s safety belt system.
Some booster seats have a shoulder belt positioner,
and some high-back booster seats have a five-point
harness. A booster seat can also help a child to see
out the window.

Securing an Add-on Child Restraint in
the Vehicle
Q: How Should I Use a Child Restraint?
A: A child restraint system is any device designed for
use in a motor vehicle to restrain, seat, or position
children. A built-in child restraint system is a
permanent part of the motor vehicle. An add-on
child restraint system is a portable one, which
is purchased by the vehicle’s owner. To help reduce
injuries, an add-on child restraint must be secured
in the vehicle. With built-in or add-on child
restraints, the child has to be secured within the
child restraint.
{CAUTION:
A child can be seriously injured or killed in a
crash if the child restraint is not properly
secured in the vehicle. Make sure the child
restraint is properly installed in the vehicle
using the vehicle’s safety belt or LATCH
system, following the instructions that came
with that restraint, and also the instructions in
this manual.
When choosing an add-on child restraint, be sure
the child restraint is designed to be used in a
vehicle. If it is, it will have a label saying that it
meets federal motor vehicle safety standards. Then
follow the instructions for the restraint. You may
find these instructions on the restraint itself or in a
booklet, or both.
To help reduce the chance of injury, the child restraint
must be secured in the vehicle. Child restraint systems
must be secured in vehicle seats by lap belts or the
lap belt portion of a lap-shoulder belt, or by the LATCH
system. See Lower Anchors and Tethers for Children

properly secured in the vehicle.

When securing an add-on child restraint, refer to the
instructions that come with the restraint which may be on
the restraint itself or in a booklet, or both, and to this
manual. The child restraint instructions are important, so
if they are not available, obtain a replacement copy
from the manufacturer.
{CAUTION:
A child can be seriously injured or killed in a
crash if the child is not properly secured in the
child restraint. Make sure the child is properly
secured, following the instructions that came
with that restraint.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle. Be sure to properly secure
any child restraint in your vehicle — even when no child
is in it.
Because there are different systems, it is important to
refer to the instructions that come with the restraint.
A child can be endangered in a crash if the child is not
properly secured in the child restraint.
Securing the Child Within the Child
Restraint
There are several systems for securing the child within
the child restraint. One system, the three-point
harness, has straps that come down over each of the
infant’s shoulders and buckle together at the crotch. The
five-point harness system has two shoulder straps,
two hip straps, and a crotch strap. A shield may take the
place of hip straps. A T-shaped shield has shoulder
straps that are attached to a flat pad which rests
low against the child’s body. A shelf- or armrest-type
shield has straps that are attached to a wide, shelf-like
shield that swings up or to the side.

Where to Put the Restraint
{CAUTION:
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Never put a child in a rear-facing child restraint in
the right front passenger seat unless your vehicle has
the passenger sensing system or an airbag off
switch and the passenger airbag status indicator or the
airbag off light shows off. Never put a rear facing
child restraint in the right front passenger seat unless
the airbag is off.
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inflates. This is because
the back of the rear-facing child restraint
would be very close to the inflating airbag.
Even though the passenger sensing system or
the airbag off switch is designed to turn off the
right front passenger’s frontal airbag if the
system detects a rear-facing child restraint, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is turned
off. We recommend that rear-facing child
restraints be secured in the rear seat, even if
the airbag is off.
If your vehicle has a rear seat that will accommodate a
rear-facing child restraint, there is a label on your
sun visor that says, ″Never put a rear-facing child seat
in the front.″ This is because the risk to the rear-facing
child is so great, if the airbag deploys.
If you need to secure a forward-facing child
restraint in the right front seat, always move
the front passenger seat as far back as it will
go. It is better to secure the child restraint in a
rear seat.

Wherever you install a child restraint, be sure to secure
the child restraint properly.
When installing a child restraint with a top tether, you
must also use either the lower anchors or the safety
belts to properly secure the child restraint. A child
restraint must never be installed using only the top tether
strap and anchor.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle. Be sure to properly secure
any child restraint in your vehicle — even when no child
is in it.
In order to use the LATCH system in your vehicle, you
need a child restraint equipped with LATCH
attachments. The child restraint manufacturer will
provide you with instructions on how to use the child
restraint and its attachments. The following explains how
to attach a child restraint with these attachments in
your vehicle.

Lower Anchors
Top Tether Anchor
Lower anchors (A) are metal bars built into the vehicle.
There are two lower anchors for each LATCH seating
position that will accommodate a child restraint with
lower attachments (B).
A top tether (A, C) anchors the top of the child restraint
to the vehicle. A top tether anchor is built into the
vehicle. The top tether attachment (B) on the child
restraint connects to the top tether anchor in the vehicle
in order to reduce the forward movement and rotation
of the child restraint during driving or in a crash.
Your child restraint may have a single tether (A) or a
dual tether (C). Either will have a single attachment (B)
to secure the top tether to the anchor.
Some top tether-equipped child restraints are designed
for use with or without the top tether being attached.
Others require the top tether always to be attached.

In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached. In the United States, some child restraints also
have a top tether. Be sure to read and follow the
instructions for your child restraint.
See the information following for installing a child
restraint with a top tether in the second row center
position.
Do not install three child restraints in the rear seat and
never install two top tethers using the same top
tether anchor.
If the child restraint does not have a top tether, one can
be obtained, in kit form, for many child restraints. Ask
the child restraint manufacturer whether or not a kit
is available.

information.
{CAUTION:
Each top tether anchor and lower anchor in the
vehicle is designed to hold only one child
restraint. Attaching more than one child
restraint to a single anchor could cause the
anchor or attachment to come loose or even
break during a crash. A child or others could
be injured if this happens. To help prevent
injury to people and damage to your vehicle,
attach only one child restraint per anchor.
Securing a Child Restraint Designed for

Here are the most important things to know about the
airbag system:
{CAUTION:
{CAUTION:
Airbags inflate with great force, faster than the
blink of an eye. If you are too close to an
inflating airbag, as you would be if you were
leaning forward, it could seriously injure you.
Safety belts help keep you in position before
and during a crash. Always wear your safety
belt, even with airbags. The driver should sit
as far back as possible while still maintaining
control of the vehicle.
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Airbags are “supplemental
restraints” to the safety belts. Airbags are
“supplemental restraints” to the safety belts.
Airbags are designed to work with safety belts,
but do not replace them. Airbags are designed
to deploy in moderate to severe frontal and
near frontal crashes. They are not designed to
inflate in rollover, rear crashes, or in many
side crashes. And, for some unrestrained
occupants, airbags may provide less
protection in frontal crashes than more
forceful airbags have provided in the past.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an
airbag for that person.

Where Are the Airbags?
Anyone who is up against, or very close to,
any airbag when it inflates can be seriously
injured or killed. Airbags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,

{CAUTION:
If something is between an occupant and an
airbag, the bag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering.
When Should an Airbag Inflate?
The driver’s and right front passenger’s frontal airbags
are designed to inflate in moderate to severe frontal or
near-frontal crashes. But they are designed to inflate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to inflate and help
restrain the occupants. Whether your frontal airbags will
or should deploy is not based on how fast your vehicle is
traveling. It depends largely on what you hit, the direction
of the impact and how quickly your vehicle slows down.
If your vehicle has one, the right front passenger’s
airbag is in the instrument panel on the
passenger’s side.

Frontal airbags may inflate at different crash speeds.
For example:
You can find the GVWR on the certification label on the
rear edge of the driver’s door. See Loading Your
• If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
Single Stage Airbags
If your vehicle has frontal airbags with single stage
deployment and your vehicle goes straight into a wall
that does not move or deform, the threshold level
is about 9 to 16 mph (14 to 26 km/h). (The threshold
level can vary, however, with specific vehicle design, so
that it can be somewhat above or below this range.)
• If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed than
if the vehicle hits an object that does not deform.
• If the vehicle hits a narrow object (like a pole) the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
Dual Stage Airbags
• If the vehicle goes into an object at an angle the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
If your vehicle has frontal airbags with dual stage
deployment, the restraint will adjust according to the
crash severity. Your vehicle is equipped with electronic
frontal sensors which help the sensing system
distinguish between a moderate and a more severe
frontal impact. For moderate frontal impacts, these
airbags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall that
does not move or deform, the threshold level for the
reduced deployment is about 12 to 16 mph
(19 to 26 km/h), and the threshold level for a full
deployment is about 16 to 25 mph (26 to 40 km/h).
(The threshold level can vary, however, with specific
vehicle design, so that it can be somewhat above
or below this range.)
The frontal airbags (driver and right front passenger) are
not intended to inflate during vehicle rollovers, rear
impacts, or in many side impacts.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. Inflation is determined by what the vehicle hits,
the angle of the impact, and how quickly the vehicle
slows down in front or near-frontal impacts.
If the GVWR (Gross Vehicle Weight Rating) of your
vehicle is 8,500 lb (3 855 kg) or above, your vehicle has
single stage airbags. If the GVWR is below 8,500 lb
(3 855 kg) then your vehicle has dual stage airbags.
1-69
Download from Www.Somanuals.com. All Manuals Search And Download.
Vehicles with dual stage airbags are also equipped with
special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensors provide
information which is used to determine if the airbags
should deploy at a reduced level or at full deployment.
But airbags would not help you in many types of
collisions, including rollovers, rear impacts and many
side impacts, primarily because an occupant’s motion is
not toward those airbags. Airbags should never be
regarded as anything more than a supplement to safety
belts, and then only in moderate to severe frontal or
near-frontal collisions.
What Makes an Airbag Inflate?
What Will You See After an Airbag
Inflates?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. The
sensing system triggers a release of gas from the
inflator, which inflates the airbag. The inflator, airbag,
and related hardware are all part of the airbag modules
inside the steering wheel and in the instrument panel
in front of the right front passenger.
After an airbag inflates, it quickly deflates, so quickly that
some people may not even realize the airbag inflated.
Some components of the airbag module — the steering
wheel hub for the driver’s airbag, or the instrument panel
for the right front passenger’s airbag —will be hot for a
short time. The parts of the airbag that come into contact
with you may be warm, but not too hot to touch. There will
be some smoke and dust coming from the vents in the
deflated airbags. Airbag inflation does not prevent the
driver from seeing or being able to steer the vehicle, nor
does it stop people from leaving the vehicle.
How Does an Airbag Restrain?
In moderate to severe frontal or near-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Airbags supplement the protection
provided by safety belts. Airbags distribute the force
of the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually.

• Let only qualified technicians work on your airbag
system. Improper service can mean that your airbag
system will not work properly. See your dealer for

{CAUTION:
When an airbag inflates, there is dust in the
air. This dust could cause breathing problems
for people with a history of asthma or other
breathing trouble. To avoid this, everyone in
the vehicle should get out as soon as it is safe
to do so. If you have breathing problems but
cannot get out of the vehicle after an airbag
inflates, then get fresh air by opening a
window or a door. If you experience breathing
problems following an airbag deployment, you
should seek medical attention.

The passenger sensing system works with sensors that
are part of the right front passenger’s seat. The
sensors are designed to detect the presence of a
properly-seated occupant and determine if the
passenger’s frontal airbag should be enabled (may
inflate) or not.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inflates. This is because
the back of the rear-facing child restraint
would be very close to the inflating airbag.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Even though the passenger sensing system is
designed to turn off the passenger’s frontal
airbag if the system detects a rear-facing child
restraint, no system is fail-safe, and no one
can guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured in the
rear seat, even if the airbag is off.
If your vehicle has a rear seat, it will accommodate
a rear-facing child restraint. A label on your sun visor
says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing child is
so great, if the airbag deploys.
If you need to secure a forward-facing child
restraint in the right front seat, always move
the front passenger seat as far back as it will
go. It is better to secure the child restraint in a
rear seat.

The passenger sensing system is designed to enable
(may inflate) the right front passenger’s frontal
airbag anytime the system senses that a person of adult
size is sitting properly in the right front passenger’s
seat. When the passenger sensing system has allowed
the airbag to be enabled, the on indicator will light
and stay lit to remind you that the airbag is active.
• the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
• or if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
passenger’s frontal airbag, the off indicator on the
instrument panel will light and stay lit to remind you that
the airbag is off.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s frontal
airbag, depending upon the person’s seating posture
and body build. Everyone in your vehicle who has
outgrown child restraints should wear a safety belt
properly — whether or not there is an airbag for
that person.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint
following the child restraint manufacturer’s directions
and refer to Securing a Child Restraint in the Right Front
Seat Position (With Passenger Sensing System) in
the Index.
If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat. If
this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s airbag.
If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position if one is available
and check with your dealer.

Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver.
The receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.

1. Use an object like a coin to pry open the transmitter.
Battery Replacement
2. Once the transmitter is separated, use an object
like a pencil to remove the old battery. Do not use
a metal object.
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
Youcan tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
3. Remove and replace the battery, positive (+)
side down.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
Notice: When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
5. Press and hold the lock and unlock buttons on the
remote keyless entry transmitter for seven seconds
to resynchronize the transmitter.

Theft-Deterrent Systems
Starting and Operating Your
Vehicle
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
New Vehicle Break-In
Passlock®
Notice: Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock® is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
• Keep your speed at 55 mph (88 km/h) or less for
the first 500 miles (805 km).
• Do not drive at any one constant speed, fast or
slow, for the first 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
During normal operation, the SECURITY light will go off
approximately five seconds after the key is turned to
• Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
If the engine stalls and the SECURITY light flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn the
engine off. However, your Passlock® system is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by Passlock® at this time.
You may also want to check the fuse. See Fuses and
service.
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Notice: If your key seems stuck in LOCK and you
cannot turn it, be sure you are using the correct key;
if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.
Ignition Positions
B (ACCESSORY): This position lets you use things like
the radio and the windshield wipers when the engine
is off.
Notice: Lengthy operation of features such as the
radio in the accessory ignition position may drain the
battery and prevent your vehicle from starting. Do not
operate your vehicle in the accessory ignition
position for a long period of time.
C (RUN): This is the position for driving.
D (START): This position starts the engine.
Use the key to turn the ignition switch to four different
positions.
A (LOCK): This position locks the ignition and
transmission. It is a theft-deterrent feature. You will only
be able to remove the key when the ignition is turned
to LOCK.
Retained Accessory Power (RAP)
The Retained Accessory Power (RAP) feature will allow
certain features on your vehicle to continue to work
for up to 10 minutes after the ignition key is turned to
LOCK or until one of the doors is opened.

When starting your engine in very cold weather
(below 0°F or −18°C), do this:
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N). Your
engine will not start in any other position — that is a
safety feature. To restart when you are already moving,
use NEUTRAL (N) only. If you have a diesel engine, refer
to the diesel supplement for the starting procedure.
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of
the key.
2. If your engine still will not start, or starts but then
stops, it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briefly but then stops again, do the
same thing, but this time keep the pedal down
for five or six seconds. This clears the extra
gasoline from the engine.
Notice: Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
Notice: Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
Notice: Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.
2. If it does not start within 10 seconds, push the
accelerator pedal all the way to the floor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.

Fuel Regulator
{CAUTION:
Your vehicle has a fuel regulator that shuts the fuel off
when the engine reaches 5,600 rpm.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a fire. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
Engine Coolant Heater
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also have
an internal thermostat in the plug end of the cord. This
will prevent operation of the engine coolant heater
when the temperature is at or above 0°F (−18°C) as
noted on the cord.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.
To Use the Engine Coolant Heater
1. Turn off the engine.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
2. Open the hood and unwrap the electrical cord.
The cord for the engine coolant heater is located
on the driver’s side of the engine compartment and
is attached to the hose for the power steering
reservoir.
3. Plug it into a normal, grounded 110-volt AC outlet.

Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. With the ignition in RUN,
you must fully apply your regular brakes before you can
shift from PARK (P).
Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way
into PARK (P) as you continue pressing the brake pedal.
Then move the shift lever into the gear you want. See
{CAUTION:
REVERSE (R): Use this gear to back up.
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Notice: Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
page 2-23. If you are pulling a trailer, see
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
on page 4-29.
NEUTRAL (N): In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
2-21
Download from Www.Somanuals.com. All Manuals Search And Download.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than DRIVE (D). You should use THIRD (3)
when carrying a heavy load or driving on steep hills.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is firmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
You should use THIRD (3) (or, as you need to, a lower
gear) when towing a trailer to minimize heat build-up
and extend the life of your transmission.
SECOND (2): This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on. If you
manually select SECOND (2), the transmission will drive
in SECOND (2). You may use this feature for reducing
torque to the rear wheels when you are trying to
start your vehicle from a stop on slippery road surfaces.
Notice: Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
FIRST (1): This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transmission will not
shift into first gear until the vehicle is going slowly
enough.
DRIVE (D): This position is for normal driving. If
you need more power for passing, and you are:
• Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
• Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
You will shift down to the next gear and have more
power.

down with your right foot. Push down the parking
brake pedal with your left foot.
{CAUTION:
If the ignition is on, the brake system warning light will
come on.
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake firmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level

page 4-37.
To release the parking brake, hold the regular brake
pedal down. Pull the handle, located just above
the parking brake pedal, marked BRAKE RELEASE to
release the parking brake.
If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice: Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.

Leaving Your Vehicle With the Engine
Running
Torque Lock
If you are parking on a hill and you do not shift your
vehicle into PARK (P) properly, the weight of the vehicle
may put too much force on the parking pawl in the
transmission. You may find it difficult to pull the shift
lever out of PARK (P). This is called torque lock.
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat. To find out how, see Shifting Into Park (P)
on page 2-23.
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake firmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch fire.
You or others could be injured. Do not leave
your vehicle with the engine running.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and the
parking brake is firmly set before you leave it. After you
move the shift lever into PARK (P), hold the regular
brake pedal down. Then, see if you can move the shift
lever away from PARK (P) without first pulling it
toward you. If you can, it means that the shift lever was
not fully locked into PARK (P).

Shifting Out of Park (P)
Parking Over Things That Burn
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. See Automatic Transmission
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up into
PARK (P) as you maintain brake application. Then,
move the shift lever into the gear you want.
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Turn the key to LOCK.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive
gear you want.
5. Have the system fixed as soon as you can.

you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Also, idling in a closed-in place can let deadly

Cruise Control
If your vehicle has cruise control, you can maintain a
speed of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can really
help on long trips. Cruise control does not work at
speeds below about 25 mph (40 km/h).
If you apply your brakes, the cruise control will
disengage.
{CAUTION:
9(Off): This position turns the system off.
R(On): This position activates the system.
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
S (Resume/Accelerate): Push the lever to this symbol
to make the vehicle accelerate or resume to a
previously set speed.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.
T (Set): Press this button to set the speed.
3-10
Download from Www.Somanuals.com. All Manuals Search And Download.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch from on to
resume/accelerate briefly.
Setting Cruise Control
You’ll go right back up to your chosen speed and
stay there.
{CAUTION:
If you hold the switch at resume/accelerate briefly, the
vehicle will keep going faster until you release the switch
or apply the brake. So unless you want to go faster,
don’t hold the switch at resume/accelerate.
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
1. Move the cruise control switch to on.
2. Get up to the speed you want.
• Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You’ll now cruise at the higher speed.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
• Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch to resume/accelerate briefly. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
The CRUISE light on the instrument panel will illuminate
when the cruise control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.

When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers find this to be too much trouble and don’t use
cruise control on steep hills.
Reducing Speed While Using Cruise
Control
• Press and hold the set button at the end of the
lever until you reach the lower speed you want, then
release it.
Ending Cruise Control
• To slow down in very small amounts, press the set
button briefly. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
There are three ways to turn off the cruise control:
• Step lightly on the brake pedal.
• Move the cruise control switch to off.
Passing Another Vehicle While Using
Cruise Control
• If your vehicle has the StabiliTrak® feature, cruise
control will deactivate if road conditions cause
StabiliTrak® to activate.
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.

Defogging and Defrosting
1(Defrost): This setting operates the defroster. Most
of the air comes out near the windshield, with some
going to the floor outlets and front side windows. The air
conditioning compressor may operate in this setting to
dehumidify the air.
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control is used properly.
There are two modes to clear fog or frost from your
windshield and side windows.
The defog setting is useful for cold weather with a large
number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high. Do not
drive the vehicle until all the windows are clear.
Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice from the
windshield before defrosting.
Turn the knob on the right of the climate control panel
to select the defog or defrost mode.
-(Defog): With this setting, the outside air comes out
of both the floor and defroster outlets. Adjust the
temperature knob for warmer or cooler air. The air

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will help
you locate them.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you

Speedometer and Odometer
Trip Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
Your odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
Press the reset button, located on the instrument panel
cluster next to the trip odometer display, to toggle
between the trip odometer and the regular odometer.
Holding the reset button for approximately one second
while the trip odometer is displayed will reset it.
Your vehicle has a tamper resistant odometer. The
digital odometer will read 999,999 if someone tries to
turn it back.
To display the odometer reading with the ignition off,
press the reset button.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it can’t, then it’s set at zero and a label must
be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Engine Speed Limiter
Your vehicle may have this feature. This system
automatically controls top vehicle speed. The system
controller receives a signal from the vehicle speed sensor
and reduces power when the vehicle speed reaches the
maximum 65 mph (105 km/h) governed speed.

Passenger Airbag Status Indicator
{CAUTION:
If your vehicle has the passenger sensing system
then your instrument panel has a passenger airbag

If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inflate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identified as a member
of a passenger airbag risk group sit in the right

If the on indicator comes on when you have a
rear-facing child restraint installed in the right
front passenger’s seat, it means that the
passenger sensing system has not turned off

briefly when you turn on
the ignition, before starting
the engine, as a check
to show you it is working.
After the engine starts, the light should go out. If it stays
on or comes on while you are driving, you may have
a problem with your charging system. It could indicate a
problem with the generator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as the
radio and air conditioner.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the

Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The Check Engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
• Light Flashing — A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
• Light On Steady — An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
Notice: If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may
not be as good, and your engine may not run as
smoothly. This could lead to costly repairs that

Emissions Inspection and Maintenance
Programs
Oil Pressure Gage
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
United States
Canada
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in kPa
(kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.

Radio Reception
Care of the Cassette Tape Player
You may experience frequency interference and static
during normal radio reception if items such as cellphone
chargers, vehicle convenience accessories, and
external electronic devices are plugged into the
accessory power outlet. If there is interference or static,
unplug the item from the accessory power outlet.
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat. If they are not, they may not operate
properly or may cause failure of the tape player.
The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLEAN to
indicate that the tape player has been used for 50 hours
without resetting the tape clean timer. If this message
appears on the display, the cassette tape player
needs to be cleaned. It will still play tapes, but it should
be cleaned as soon as possible to prevent damage
to the tapes and player. If there is a reduction in sound
quality, try a known good cassette to see if the tape
or the tape player is at fault. If this other cassette has no
improvement in sound quality, clean the tape player.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. For
better radio reception, most AM radio stations will boost
the power levels during the day, and then reduce
these levels during the night. Static can also occur when
things like storms and power lines interfere with radio
reception. When this happens, try reducing the treble on
your radio.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer.
FM Stereo
FM stereo will give the best sound, but FM signals will
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to fade in and out.
3-75
Download from Www.Somanuals.com. All Manuals Search And Download.
When cleaning the cassette tape player with the
recommended non-abrasive cleaning cassette, it is
possible that the cassette may eject, because the cut
tape detection feature on the radio may recognize it as a
broken tape, in error. To prevent the cleaning cassette
from being ejected, use the following steps:
After the player is cleaned, press and hold the eject
button for five seconds to reset the CLEAN indicator.
The radio will display --- or CLEANED to show the
indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before the tape player is
serviced.
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE DISC button for
five seconds. READY will appear on the display and
the cassette symbol will flash for five seconds.
Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. The CD player scans the bottom
surface of the disc. If the surface of a CD is damaged,
such as cracked, broken, or scratched, the CD will
not play properly or not at all. If the surface of a CD is
soiled, take a soft, lint free cloth or dampen a clean, soft
cloth in a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process starts
from the center to the edge.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
When the cleaning cassette has been ejected, the
cut tape detection feature will be active again.
A non-scrubbing action, wet-type cleaner which uses a
cassette with a fabric belt to clean the tape head
can be used. This type of cleaning cassette will not
eject on its own. A non-scrubbing action cleaner may not
clean as thoroughly as the scrubbing type cleaner.
The use of a non-scrubbing action, dry-type cleaning
cassette is not recommended.
Do not touch the bottom side of a CD while handling it;
this could damage the surface. Pick up CDs by
grasping the outer edges or the edge of the hole and
the outer edge.

advised, due to the risk of contaminating the internal
lens of the CD optics with lubricants.
The radio is used to adjust the vehicle’s chime level.
To change the volume level of the chime, press and hold
pushbutton 6 with the ignition on and the radio power
off. The volume level will change from the normal
level to loud, and LOUD will appear on the radio display.
To change back to the default or normal setting,
press and hold pushbutton 6 again. The volume level
will change from the loud level to normal, and NORMAL
will appear on the radio display. Each time the chime
volume is changed, three chimes will sound to indicate
the change. Removing the radio and not replacing it
with a factory radio or chime module will disable
vehicle chimes.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, straighten it out by hand. If the
mast is badly bent, replace it.
Check occasionally to make sure the mast is still
tightened to the fender. If tightening is required, tighten
by hand, then with a wrench one quarter turn.

Your Driving, the Road, and
Your Vehicle
{CAUTION:
Defensive driving really means “Be ready for
anything.” On city streets, rural roads, or
expressways, it means “Always expect the
unexpected.” Assume that pedestrians or other
drivers are going to be careless and make
mistakes. Anticipate what they might do and
be ready. Rear-end collisions are about the
most preventable of accidents. Yet they are
common. Allow enough following distance.
Defensive driving requires that a driver
concentrate on the driving task. Anything that
distracts from the driving task makes proper
defensive driving more difficult and can even
cause a collision, with resulting injury. Ask a
passenger to help do these things, or pull off
the road in a safe place to do them. These
simple defensive driving techniques could
save your life.
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start with a very important safety device in your
vehicle: Buckle up. See Safety Belts: They Are for

The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive. But what if people do? How much is “too
much” if someone plans to drive? It is a lot less
than many might think. Although it depends on each
person and situation, here is some general information
on the problem.
Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy. It is the number one contributor
to the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to drive a
vehicle:
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:
• Judgment
• The amount of alcohol consumed
• The drinker’s body weight
• Muscular Coordination
• Vision
• The amount of food that is consumed before and
during drinking
• Attentiveness
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was
drinking and driving. In recent years, more than
16,000 annual motor vehicle-related deaths have been
associated with the use of alcohol, with more than
300,000 people injured.
• The length of time it has taken the drinker to
consume the alcohol
According to the American Medical Association, a 180 lb
(82 kg) person who drinks three 12 ounce (355 ml)
bottles of beer in an hour will end up with a BAC
of about 0.06 percent. The person would reach the
same BAC by drinking three 4 ounce (120 ml) glasses
of wine or three mixed drinks if each had 1-1/2 ounces
(45 ml) of liquors like whiskey, gin, or vodka.
Many adults — by some estimates, nearly half the adult
population — choose never to drink alcohol, so they
never drive after drinking. For persons under 21,
it is against the law in every U.S. state to drink alcohol.
There are good medical, psychological, and
developmental reasons for these laws.
4-3

There is a gender difference, too. Women generally
have a lower relative percentage of body water
than men. Since alcohol is carried in body water, this
means that a woman generally will reach a higher BAC
level than a man of her same body weight will when
each has the same number of drinks.
The law in most U.S. states, and throughout Canada,
sets the legal limit at 0.08 percent. In some other
countries, the limit is even lower. For example, it is
0.05 percent in both France and Germany. The BAC limit
for all commercial drivers in the United States is
0.04 percent.
The BAC will be over 0.10 percent after three to
six drinks (in one hour). Of course, as we have seen,
it depends on how much alcohol is in the drinks,
and how quickly the person drinks them.
But the ability to drive is affected well below a BAC of
0.10 percent. Research shows that the driving skills
of many people are impaired at a BAC approaching
0.05 percent, and that the effects are worse at night.
All drivers are impaired at BAC levels above
0.05 percent. Statistics show that the chance of being in
a collision increases sharply for drivers who have a
BAC of 0.05 percent or above. A driver with a BAC level
of 0.06 percent has doubled his or her chance of
having a collision. At a BAC level of 0.10 percent, the
chance of this driver having a collision is 12 times
greater; at a level of 0.15 percent, the chance is
25 times greater!
It is the amount of alcohol that counts. For example, if
the same person drank three double martinis (3 ounces
or 90 ml of liquor each) within an hour, the person’s
BAC would be close to 0.12 percent. A person
who consumes food just before or during drinking will
have a somewhat lower BAC level.

The body takes about an hour to rid itself of the alcohol in
one drink. No amount of coffee or number of cold
showers will speed that up. “I will be careful” is not the
right answer. What if there is an emergency, a need to
take sudden action, as when a child darts into the street?
A person with even a moderate BAC might not be able to
react quickly enough to avoid the collision.
{CAUTION:
Drinking and then driving is very dangerous.
Your reflexes, perceptions, attentiveness, and
judgment can be affected by even a small
amount of alcohol. You can have a serious — or
even fatal — collision if you drive after drinking.
Please do not drink and drive or ride with a
driver who has been drinking. Ride home in a
cab; or if you are with a group, designate a
driver who will not drink.
There is something else about drinking and driving that
many people do not know. Medical research shows that
alcohol in a person’s system can make crash injuries
worse, especially injuries to the brain, spinal cord, or
heart. This means that when anyone who has been
drinking — driver or passenger — is in a crash, that
person’s chance of being killed or permanently disabled
is higher than if the person had not been drinking.
Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering, and
the accelerator. All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you are driving on snow or ice, it
is easy to ask more of those control systems than
the tires and road can provide. That means you can lose
control of your vehicle.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modifications
on page 5-3.

Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modifications
on page 5-3.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of your brakes;
the weight of the vehicle; and the amount of brake
force applied.

Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. See Anti-Lock
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
4-7
Download from Www.Somanuals.com. All Manuals Search And Download.
The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may feel
the brakes vibrate, or you may notice some noise,
but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
Locking Rear Axle
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction
and the other does, this feature will allow the wheel with
traction to move the vehicle.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.

the system off if your vehicle is stuck in sand, mud, ice
or snow, and you want to “rock” your vehicle to
attempt to free it. See If Your Vehicle is Stuck in Sand,

automatically activate to assist the driver in maintaining
vehicle directional control in most driving conditions.
When activated, the StabiliTrak® system may reduce
engine power to the wheels and apply braking to
individual wheels as necessary to assist the driver with
vehicle directional control. If your vehicle is in cruise
control when the system activates, the StabiliTrak®
indicator light on the instrument panel will flash, and the
cruise control will automatically disengage. When the
StabiliTrak® system is no longer active, you may

To turn on the StabiliTrak® system, press the
StabiliTrak® button again. StabiliTrak® will automatically
turn back on when the vehicle speed exceeds
20 mph (32 km/h). You will hear one chime and the
StabiliTrak® not ready light will turn off.
The StabiliTrak® system may also turn off automatically
if it determines that a problem exists with the system.
If the problem does not clear itself after restarting
the vehicle, you should see your dealer for service.
When the StabiliTrak® system has been turned off you
may still hear system noises as a result of the
brake-traction control coming on.

Traction Control Operation
All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive, your engine’s driving
power is sent to all four wheels for extra traction
when needed.
The traction control system is part of the StabiliTrak®
system. Traction control limits wheel spin by reducing
engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
This is like four-wheel drive, but there is no separate
lever or switch to engage or disengage the front axle. It
is fully automatic, and adjusts itself as needed for
road conditions.
If the brake-traction control system activates constantly
or if the brakes have heated up due to high speed
braking, the brake-traction control will be automatically
disabled. The system will come back on after the
brakes have cooled. This can take up to two minutes or
longer depending on brake usage.
You may experience a brief vehicle vibration upon
acceleration when driving in slippery conditions. This is
normal and is an indication that the all-wheel drive
system is functioning properly.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens you may
notice a reduction in acceleration, or may hear a noise
or vibration. This is normal.

performance. See Accessories and Modifications

Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do their
work where the tires meet the road. Adding the sudden
acceleration can demand too much of those places.
You can lose control.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
What should you do if this ever happens? Ease up on
the accelerator pedal, steer the vehicle the way you
want it to go, and slow down.
Steering Tips
It is important to take curves at a reasonable speed.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions. Under
less favorable conditions you will want to go slower.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can “drive” through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you are in a curve, speed is the one factor you
can control.

performance. See Accessories and Modifications
on page 5-3.

Steering in Emergencies
There are times when steering can be more effective than
braking. For example, you come over a hill and find a
truck stopped in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front of you. You can avoid these
problems by braking — if you can stop in time. But
sometimes you cannot; there is not room. That is the time
for evasive action — steering around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes.
speed as you can from a possible collision. Then
steer around the problem, to the left or right depending
on the space available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you
can turn it a full 180 degrees very quickly without
removing either hand. But you have to act fast, steer
quickly, and just as quickly straighten the wheel
once you have avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.

Off-Road Recovery
Passing
You may find that your right wheels have dropped off the
edge of a road onto the shoulder while you are driving.
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then
goes back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds. A miscalculation, an error in
judgment, or a brief surrender to frustration or anger
can suddenly put the passing driver face to face with the
worst of all traffic accidents — the head-on collision.
So here are some tips for passing:
• Drive ahead. Look down the road, to the sides and to
crossroads for situations that might affect your
passing patterns. If you have any doubt whatsoever
about making a successful pass, wait for a
better time.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way,
steer so that your vehicle straddles the edge of
the pavement. You can turn the steering wheel up to
one-quarter turn until the right front tire contacts
the pavement edge. Then turn your steering wheel to go
straight down the roadway.
• Watch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it is all right to pass,
providing the road ahead is clear. Never cross a solid
line on your side of the lane or a double solid line,
even if the road seems empty of approaching traffic.
4-14

• Do not get too close to the vehicle you want to pass
while you are awaiting an opportunity. For one thing,
following too closely reduces your area of vision,
especially if you are following a larger vehicle. Also,
you will not have adequate space if the vehicle
ahead suddenly slows or stops. Keep back a
reasonable distance.
• Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. Remember that
your passenger side outside mirror is convex. The
vehicle you just passed may seem to be farther away
from you than it really is.
• When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and do
not get too close. Time your move so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have a
running start that more than makes up for the
distance you would lose by dropping back. And if
something happens to cause you to cancel your
pass, you need only slow down and drop back again
and wait for another opportunity.
• Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the next
vehicle.
• Do not overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
• If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps you can
ease a little to the right.
• If other vehicles are lined up to pass a slow vehicle,
wait your turn. But take care that someone is not
trying to pass you as you pull out to pass the slow
vehicle. Remember to glance over your shoulder and
check the blind spot.

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver
has asked.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
Skidding
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including engine braking by shifting to a
lower gear. Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow
on the road to make a mirrored surface — and
slow down when you have any doubt.
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
Remember: Any Anti-Lock Brake System (ABS) helps
avoid only the braking skid.
A cornering skid is best handled by easing your foot off
the accelerator pedal.

What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired — by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
• Drive defensively.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust to the dark. When
you are faced with severe glare, as from a driver
who does not lower the high beams, or a vehicle with
misaimed headlamps, slow down a little. Avoid
staring directly into the approaching headlamps.
• Do not drink and drive.
• Adjust the inside rearview mirror to reduce the glare
from headlamps behind you.
• Since you cannot see as well, you may need to
slow down and keep more space between you
and other vehicles.
Keep the windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made
much worse by dirt on the glass. Even the inside of the
glass can build up a film caused by dust. Dirty glass
makes lights dazzle and flash more than clean
glass would, making the pupils of your eyes contract
repeatedly.
• Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
• In remote areas, watch for animals.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from
night blindness — the inability to see in dim light — and
are not even aware of it.
• If you are tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But
as we get older these differences increase. A
50-year-old driver may require at least twice as much
light to see the same thing at night as a 20-year-old.

The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are in good shape, a heavy
rain can make it harder to see road signs and
traffic signals, pavement markings, the edge of the road,
and even people walking.
Driving in Rain and on Wet Roads
It is wise to keep your wiping equipment in good shape
and keep your windshield washer fluid reservoir filled
with washer fluid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas
on the windshield, or when strips of rubber start
to separate from the inserts.
{CAUTION:
Wet brakes can cause accidents. They will not
work as well in a quick stop and may cause
pulling to one side. You could lose control of
the vehicle.
Rain and wet roads can mean driving trouble. On a wet
road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as on
dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is always wise to
go slower and be cautious if rain starts to fall while
you are driving. The surface may get wet suddenly when
your reflexes are tuned for driving on dry pavement.
After driving through a large puddle of water
or a car wash, apply your brake pedal lightly
until your brakes work normally.
Driving too fast through large water puddles or even
going through some car washes can cause problems,
too. The water may affect your brakes. Try to avoid
puddles. But if you cannot, try to slow down before you
hit them.

Hydroplaning
Driving Through Flowing Water
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
{CAUTION:
Flowing or rushing water creates strong forces.
If you try to drive through flowing water, as you
might at a low water crossing, your vehicle can
be carried away. As little as six inches of
flowing water can carry away a smaller vehicle.
If this happens, you and other vehicle
occupants could drown. Do not ignore police
warning signs, and otherwise be very cautious
about trying to drive through flowing water.
Hydroplaning does not happen often. But it can if your
tires do not have much tread or if the pressure in
one or more is low. It can happen if a lot of water is
standing on the road. If you can see reflections
from trees, telephone poles, or other vehicles, and
raindrops dimple the water’s surface, there could be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just is not a hard and fast rule about hydroplaning.
The best advice is to slow down when it is raining.
Some Other Rainy Weather Tips
Driving Through Deep Standing Water
• Besides slowing down, allow some extra following
distance. And be especially careful when you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared to have your
view restricted by road spray.
Notice: If you drive too quickly through deep
puddles or standing water, water can come in
through your engine’s air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle. If
you cannot avoid deep puddles or standing water,
drive through them very slowly.

Here are ways to increase your safety in city driving:
City Driving
• Know the best way to get to where you are
going. Get a city map and plan your trip into
an unknown part of the city just as you would for a
cross-country trip.
• Try to use the freeways that rim and crisscross
most large cities. You will save time and energy.
• Treat a green light as a warning signal. A traffic
light is there because the corner is busy enough
to need it. When a light turns green, and just before
you start to move, check both ways for vehicles
that have not cleared the intersection or may
be running the red light.
One of the biggest problems with city streets is the
amount of traffic on them. You will want to watch out for
what the other drivers are doing and pay attention to
traffic signals.

The most important advice on freeway driving is: Keep
up with traffic and keep to the right. Drive at the
same speed most of the other drivers are driving.
Too-fast or too-slow driving breaks a smooth traffic flow.
Treat the left lane on a freeway as a passing lane.
Freeway Driving
At the entrance, there is usually a ramp that leads to the
freeway. If you have a clear view of the freeway as you
drive along the entrance ramp, you should begin to check
traffic. Try to determine where you expect to blend with
the flow. Try to merge into the gap at close to the
prevailing speed. Switch on your turn signal, check your
mirrors, and glance over your shoulder as often as
necessary. Try to blend smoothly with the traffic flow.
Once you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate if it is slower.
Stay in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use
your turn signal.
Just before you leave the lane, glance quickly over your
shoulder to make sure there is not another vehicle in
your blind spot.
Mile for mile, freeways — also called thruways, parkways,
expressways, turnpikes, or superhighways — are the
safest of all roads. But they have their own special rules.
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to
move slightly slower at night.

When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
Here are some things you can check before a trip:
• Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
• Wiper Blades: Are they in good shape?
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
• Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
• Lamps: Are they all working? Are the lenses clean?
• Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Before Leaving on a Long Trip
• Weather Forecasts: What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
first part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
• Maps: Do you have up-to-date maps?
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will find experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.

Highway Hypnosis
Hill and Mountain Roads
Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the
wind against the vehicle that can make you sleepy. Do
not let it happen to you! If it does, your vehicle can
leave the road in less than a second, and you could
crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
• Make sure your vehicle is well ventilated, with a
comfortably cool interior.
• Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
• If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
{CAUTION:
• Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system,
and transmission. These parts can work hard
on mountain roads.
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
{CAUTION:
If you do not shift down, your brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let your engine assist your brakes on a
steep downhill slope.
• Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
• Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your
engine and transmission, and you can climb the
hill better.
4-24
Download from Www.Somanuals.com. All Manuals Search And Download.
• Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at speeds
that let you stay in your own lane.
Winter Driving
• As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled car or
an accident.
• You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area, or winding roads. Be alert to these and take
appropriate action.
Here are some tips for winter driving:
• Have your vehicle in good shape for winter.
• You may want to put winter emergency supplies in
your vehicle.
4-25
Download from Www.Somanuals.com. All Manuals Search And Download.
Include an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red
cloth, and reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag
of sand, a piece of old carpet, or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where the tires meet the
road probably have good traction.
However, if there is snow or ice between the tires and
the road, you can have a very slippery situation. You will
have a lot less traction, or grip, and will need to be
very careful.
What is the worst time for this? Wet ice. Very cold snow
or ice can be slick and hard to drive on. But wet ice
can be even more trouble because it may offer the least
traction of all. You can get wet ice when it is about
freezing, 32°F (0°C), and freezing rain begins to fall. Try
to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition — smooth ice, packed, blowing,
or loose snow — drive with caution.
4-26
Download from Www.Somanuals.com. All Manuals Search And Download.
Accelerate gently. Try not to break the fragile traction.
If you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with
your vehicle unless you know for sure that you are near
help and you can hike through the snow. Here are
some things to do to summon help and keep yourself
and your passengers safe:
Your Anti-Lock Brake System (ABS) improves your
vehicle’s stability when you make a hard stop on
a slippery road. Even though you have ABS, you will
want to begin stopping sooner than you would on
dry pavement. See Anti-Lock Brake System (ABS)
on page 4-7.
• Turn on your hazard flashers.
• Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
• Allow greater following distance on any
slippery road.
• Put on extra clothing or wrap a blanket around you.
If you do not have blankets or extra clothing, make
body insulators from newspapers, burlap bags,
rags, floor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.
• Watch for slippery spots. The road might be fine
until you hit a spot that is covered with ice. On
an otherwise clear road, ice patches may appear in
shaded areas where the sun cannot reach, such
as around clumps of trees, behind buildings,
or under bridges. Sometimes the surface of a curve
or an overpass may remain icy when the
surrounding roads are clear. If you see a patch of
ice ahead of you, brake before you are on it. Try not
to brake while you are actually on the ice, and
avoid sudden steering maneuvers.

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking the exhaust pipe and/or the fuel
operated heater exhaust system, if equipped.
And check around again from time to time to
be sure snow does not collect there. If your
vehicle has a diesel engine and a fuel operated
heater, see “Fuel Operated Heater (FOH)” in
the diesel engine supplement.
You can run the engine to keep warm, but be careful.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get
and it keeps the battery (or batteries) charged.
4-28
Download from Www.Somanuals.com. All Manuals Search And Download.
You will need a well-charged battery (or batteries) to
restart the vehicle, and possibly for signaling later
on with your headlamps. Let the heater run for a while.
{CAUTION:
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transmission or other parts of
the vehicle can overheat. That could cause an
engine compartment fire or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
If Your Vehicle is Stuck in Sand,
Mud, Ice or Snow
speedometer.
Notice: Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transmission
back and forth, you can destroy your transmission.
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as rocking
can help you get out when you are stuck, but you
must use caution.

Rocking Your Vehicle to Get It Out
Loading Your Vehicle
First, turn your steering wheel left and right. That
will clear the area around your front wheels. Then shift
back and forth between REVERSE (R) and a forward
gear, spinning the wheels as little as possible. Release
the accelerator pedal while you shift, and press
lightly on the accelerator pedal when the transmission is
in gear. By slowly spinning your wheels in the forward
and reverse directions, you will cause a rocking
motion that may free your vehicle. If that does not get
you out after a few tries, you may need to be towed out.
If you do need to be towed out, see Towing Your
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all occupants,
cargo, and all nonfactory-installed options. Two labels
on your vehicle show how much weight it was designed
to carry, the Tire and Loading Information label and
the Certification/Tire label.
{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.

There is also important loading information on the
vehicle Certification/Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and rear axle.
See “Certification/Tire Label” later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
Label Example
A vehicle specific Tire and Loading Information label is
attached to the center pillar (B-pillar). With the driver’s
door open, you will find the label attached below
the door lock post (striker). The tire and loading
information label shows the number of occupant seating
positions (A), and the maximum vehicle capacity
weight (B) in kilograms and pounds.
3. Subtract the combined weight of the driver and
passengers from XXX kg or XXX lbs.
4-31
Download from Www.Somanuals.com. All Manuals Search And Download.
4. The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if
the “XXX” amount equals 1400 lbs and there will be
five 150 lb passengers in your vehicle, the amount
of available cargo and luggage load capacity is
650 lbs (1400 − 750 (5 x 150) = 650 lbs).
5. Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight
may not safely exceed the available cargo
and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, the load from
your trailer will be transferred to your vehicle.

The Certification/Tire label also tells you the maximum
weights for the front and rear axles, called Gross
Axle Weight Rating (GAWR). To find out the actual loads
on your front and rear axles, you need to go to a
weigh station and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out your load
equally on both sides of the centerline.
Certification/Tire Label
Never exceed the GVWR for your vehicle, or the GAWR
for either the front or rear axle.
And, if you do have a heavy load, you should spread
it out.
{CAUTION:
Do not load your vehicle any heavier than the

{CAUTION:
Towing Your Vehicle
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
• Put things in the cargo area of your
vehicle. Try to spread the weight evenly.
• Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
• Do not leave an unsecured child restraint
in your vehicle.
• When you carry something inside the
vehicle, secure it whenever you can.
• Do not leave a seat folded down unless
you need to.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle — such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy” (towing your vehicle with
all four wheels on the ground) and “dolly” (towing
your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
Add-On Equipment
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing” following.
When you carry removable items, you may need to put
a limit on how many people you carry inside your
vehicle. Be sure to weigh your vehicle before you buy
and install the new equipment.

Here are some important things to consider before you
do recreational vehicle towing:
All-Wheel-Drive Vehicles
Your vehicle was not designed to be towed with all
four wheels on the ground. To properly tow these
vehicles, they should be placed on a platform trailer
with all four wheels off the ground.
• What’s the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer’s
recommendations.
Notice: Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle if
any of its wheels will be on the ground.
• How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
• Do you have the proper towing equipment?
See your dealer or trailering professional for
additional advice and equipment recommendations.
Dolly Towing
Rear Towing (Rear Wheels Off the Ground)
• Is your vehicle ready to be towed? Just as you
would prepare your vehicle for a long trip, you’ll
want to make sure your vehicle is prepared to
be towed.
Two-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle from
the rear:
Dinghy Towing
Two-Wheel-Drive Vehicles
1. Drive the vehicle onto the dolly.
Notice: If you tow your vehicle with all four wheels
on the ground, the drivetrain components could
be damaged. The repairs would not be covered by
your warranty. Do not tow your vehicle with all
four wheels on the ground.
page 2-23 for more information.
3. Put the automatic transmission in PARK (P).
4. Follow the dolly manufacturer’s instructions to attach
and secure the vehicle being towed to the dolly and
then the loaded dolly to the tow vehicle. Make
sure the wheels are straight before towing.
Two-wheel-drive vehicles should not be towed with all
four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
Use an adequate clamping device to ensure that
the front wheels are locked into the straight position.

Download from Www.Somanuals.com. All Manuals Search And Download.
5. Release the parking brake only after the vehicle
being towed is firmly attached to the tow vehicle.
Towing a Trailer
6. Turn the ignition to LOCK.
If the tow vehicle will not be started or driven for
six weeks or more, remove the battery cable
from the negative terminal (post) of the battery to
prevent your battery from draining while towing.
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well — or even
at all. You and your passengers could be
seriously injured. Pull a trailer only if you have
followed all the steps in this section. Ask your
dealer for advice and information about towing
a trailer with your vehicle.
All-Wheel-Drive Vehicles
Your vehicle was not designed to be towed with
two wheels on the ground. To properly tow these
vehicles, they should be placed on a platform trailer
with all four wheels off the ground.
Notice: Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle if
any of its wheels will be on the ground.
Notice: Pulling a trailer improperly can damage
your vehicle and result in costly repairs that would
not be covered by your warranty. Always follow
the instructions in this section and check with your
dealer for more information about towing a trailer
with your vehicle.
To identify the trailering capacity of your vehicle, you
should read the information in “Weight of the Trailer” that
appears later in this section.

Trailering is different than just driving your vehicle by
itself. Trailering means changes in acceleration, braking,
handling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and it has to be
used properly.
• Then, during the first 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
That’s the reason for this part. In it are many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully before
you pull a trailer.
• See also “Driving on Grades” later in this section.
Three important considerations have to do with weight:
• the weight of the trailer
• the weight of the trailer tongue
If You Do Decide To Pull A Trailer
• and the weight on your vehicle’s tires
If you do, here are some important points:
Tow/Haul Mode
• There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live
Tow/haul is designed to assist while your vehicle is
pulling a large or heavy load or trailer. Tow/haul is most
useful while pulling such a load in rolling terrain, in
stop-and-go traffic, or when you need improved
low-speed control, such as when parking. The purpose
of the tow/haul mode is to:
but also where you’ll be driving. A good source for
this information can be state or provincial police.
• Consider using a sway control. See “Hitches” later
in this section.
• Reduce the frequency and improve the predictability
of transmission shifts,
• Don’t tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
• provide the same solid shift feel when pulling a
heavy load as when the vehicle is unloaded,
• improve control of vehicle speed while requiring
less throttle pedal activity.

Press this button located
to the right of the steering
wheel on the instrument
panel to turn tow/haul
mode on and off.
Tow/haul is most effective when the vehicle and trailer
combined weight is at least 75 percent of the vehicle’s
Gross Combined Weight Rating (GCWR). See “Weight
of the Trailer” later in this section.
Driving with tow/haul activated without a heavy load will
cause reduced fuel economy and unpleasant engine
and transmission driving characteristics, but will
not cause damage.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. It can also depend on any
special equipment that you have on your vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this
section for more information.
While activated, the
indicator light on the
instrument panel will
be on.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
Tow/haul mode will turn off automatically when the
ignition is turned off. See Tow/Haul Mode Light

The Gross Combined Weight Rating (GCWR) is the
total allowable weight of the completely loaded vehicle
and trailer including any passengers, cargo equipment
and conversion. The GCWR for your vehicle should not
be exceeded.

The trailer tongue weight (A) should be 10 percent to
15 percent of the total loaded trailer weight (B), up to
a maximum of 1,000 lbs (454 kg) with a weight
distributing hitch.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. If you have a lot of options, equipment,
passengers or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will
also reduce the trailer weight your vehicle can tow. And
if you will tow a trailer, you must add the tongue load
to the GVW because your vehicle will be carrying
about your vehicle’s maximum load capacity.
Do not exceed the maximum allowable tongue weight
for your vehicle. Choose the shortest hitch extension
that will position the hitch ball closest to the vehicle.
This will help reduce the effect of trailer tongue weight
on the rear axle.
After you’ve loaded your trailer, weigh the trailer and then
the tongue, separately, to see if the weights are proper. If
they aren’t, you may be able to get them right simply by
moving some items around in the trailer.
Trailering may be limited by the vehicle’s ability to carry
tongue weight. Tongue weight cannot cause the vehicle
to exceed the GVWR (Gross Vehicle Weight Rating) or
the RGAWR (Rear Gross Axle Weight Rating). The effect
of additional weight may reduce your trailering capacity
more than the total of the additional weight.
The trailer tongue weight (A) should be 10 percent to
15 percent of the total loaded trailer weight (B), up to a
maximum of 400 lbs (181 kg) with a weight carrying hitch.

Consider the following example:
But let’s say your specific vehicle is equipped with some
of the latest options and you have a front seat passenger
and two rear seat passengers with some luggage and
gear in the vehicle as well. You may add 300 lbs (136 kg)
to the front axle weight and 400 lbs (181 kg) to the rear
axle weight. Your vehicle now weighs:
A vehicle model base weight is 5,500 lbs (2 495 kg);
2,800 lbs (1 270 kg) at the front axle and 2,700 lbs
(1 225 kg) at the rear axle. It has a GVWR of 7,200 lbs
(3 266 kg), a RGAWR of 4,000 lbs (1 814 kg) and a
GCWR (Gross Combination Weight Rating) of
14,000 lbs (6 350 kg). The trailer rating should be:
Weight is still below 7,200 lbs (3 266 kg) and you may
think that you should subtract 700 additional pounds
(318 kg) from your trailering capacity to stay within
GCWR limits. Your maximum trailer would only be
7,800 lbs (3 538 kg). You may go further and think you
must limit tongue weight to less than 1,000 lbs (454 kg) to
avoid exceeding GVWR. But, you must still consider the
effect on the rear axle. Because your rear axle now
weighs 3,100 lbs (1 406 kg), you can only put 900 lbs
(408 kg) on the rear axle without exceeding RGAWR.
You can expect tongue weight to be at least 10 percent
of trailer weight (850 lbs (386 kg)) and because the
weight is applied well behind the rear axle, the effect on
the rear axle will be greater than just the weight
itself, as much as 1.5 times as much. The weight at the
rear axle could be 850 lbs (386 kg) X 1.5 = 1,275 lbs
(578 kg). Since the rear axle already weighs 2,700 lbs
(1 225 kg), adding 1,275 lbs (578 kg) brings the
total to 3,975 lbs (1 803 kg). This is very close to, but
within the limit for RGAWR as well. The vehicle is set to
trailer up to 8,500 lbs (3 856 kg).
4-45

The effect of tongue weight is about 1.5 times the actual
weight. Dividing the 900 lbs (408 kg) by 1.5 leaves you
with being able to handle only 600 lbs (272 kg) of tongue
weight. Since tongue weight is usually at least 10 percent
of total loaded trailer weight, you can expect that the
largest trailer your vehicle can properly handle is
6,000 lbs (2 721 kg).
Weight-Distributing Hitches and Weight
Carrying Hitches
It is important that you make sure your vehicle does not
exceed any of its ratings — GCWR, GVWR, RGAWR,
Maximum Trailer Rating or Tongue Weight. The
only way to be sure you are not exceeding any of these
ratings is to weigh your vehicle and trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper limit
for cold tires. You’ll find these numbers on the
Certification label at the rear edge of the driver’s door or
sure you don’t go over the GVW limit for your vehicle,
or the GAWR, including the weight of the trailer tongue.
If you use a weight distributing hitch, make sure you
don’t go over the rear axle limit before you apply
the weight distribution spring bars.
(A) Body to Ground Distance, (B) Front of Vehicle
When using a weight-distributing hitch, the hitch must
be adjusted so that the distance (A) remains the
same both before and after coupling the trailer to the
tow vehicle.
If you use a step-bumper hitch, your bumper could be
damaged in sharp turns. Make sure you have ample
room when turning to avoid contact between the trailer
and the bumper.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why you’ll need the right hitch.
4-46

If you’ll be pulling a trailer that, when loaded, will weigh
more than 5,000 lbs (2 270 kg), be sure to use a
properly mounted weight-distributing hitch and sway
control of the proper size. This equipment is very
important for proper vehicle loading and good handling
when you’re driving. You should always use a sway
control if your trailer will weigh more than these limits.
You can ask a hitch dealer about sway controls.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer to help prevent the tongue from
contacting the road if it becomes separated from
the hitch. Instructions about safety chains may be
provided by the hitch manufacturer or by the trailer
manufacturer. Follow the manufacturer’s
recommendation for attaching safety chains and do not
attach them to the bumper. Always leave just enough
slack so you can turn with your rig. Never allow
safety chains to drag on the ground.
Will you have to make any holes in the body of your
vehicle when you install a trailer hitch?
If you’re using the wiring provided with the
factory-installed trailering package, you should not need
to make any holes in the body of your vehicle.
However, if you have an aftermarket hitch installed, you
may need to make holes in the body.
Trailer Brakes
If your trailer weighs more than 1,000 lbs (450 kg)
loaded, then it needs its own brakes – and they must be
adequate. Be sure to read and follow the instructions
for the trailer brakes so you’ll be able to install,
adjust and maintain them properly.
Since your vehicle is equipped with StabiliTrak®, your
trailer brake system cannot tap into the vehicle’s
hydraulic brake system.
If you do, then be sure to seal the holes later when you
remove the hitch. If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get into
your vehicle as well as dirt and water. See “Carbon

Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Driving with a Trailer
{CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide (CO) could come into your vehicle.
You can not see or smell CO. It can cause
unconsciousness or death. See Engine
when towing a trailer:
• Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
• Keep the rear-most windows closed.
• If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum air
because it only recirculates the air inside
your vehicle. See Climate Control System
in the Index.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.

Passing
Turn Signals When Towing a Trailer
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
When you tow a trailer, your vehicle has to have extra
wiring and a heavy-duty turn signal flasher (included
in the optional trailering package).
The arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you’re about to turn, change lanes or stop.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Making Turns
Notice: Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
When you’re turning with a trailer, make wider turns
than normal. Do this so your trailer won’t strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
You can tow in DRIVE (D). You may want to shift the
transmission to THIRD (3) or a lower gear under heavy
loads and/or hilly conditions.

When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK (P) for a
few minutes before turning the engine off. If you do get
page 5-24.
2. Have someone place chocks under the
trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and then shift to PARK (P).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
Parking on Hills
1. Apply your regular brakes and hold the pedal down
while you:
• start your engine,
{CAUTION:
• shift into a gear, and
• release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
4. Stop and have someone pick up and store
the chocks.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.

Adding Equipment to the Outside
of Your Vehicle
Gasoline Octane
Use regular unleaded gasoline with a posted octane
rating of 87 or higher. If the octane rating is less than 87,
you may notice an audible knocking noise when you
drive, commonly referred to as spark knock. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. If you are using gasoline rated at
87 octane or higher and you hear heavy knocking, your
engine needs service.
Things you might add to the outside of your vehicle
can affect the airflow around it. This may cause
wind noise and affect windshield washer performance.
Check with your dealer before adding equipment to
the outside of your vehicle.
Fuel
Gasoline Specifications
If your vehicle has a diesel engine, see “Diesel Fuel
Requirements and Fuel System” in the DURAMAX®
Diesel Supplement.
At a minimum, gasoline should meet ASTM specification
D 4814 in the United States or CAN/CGSB-3.5 in
Canada. Some gasolines may contain an
octane-enhancing additive called methylcyclopentadienyl
manganese tricarbonyl (MMT). General Motors
recommends against the use of gasolines containing
information.

California Fuel
Additives
If your vehicle is certified to meet California Emissions
Standards, it is designed to operate on fuels that
meet California specifications. See the underhood
emission control label. If this fuel is not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp may turn on and your vehicle may fail a
page 3-36. If this occurs, return to your authorized GM
dealer for diagnosis. If it is determined that the
condition is caused by the type of fuel used, repairs
may not be covered by your warranty.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. In most cases, you should not have to add
anything to your fuel. However, some gasolines contain
only the minimum amount of additive required to
meet U.S. Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves clean,
or if your vehicle experiences problems due to
dirty injectors or valves, look for gasoline that is
advertised as TOP TIER Detergent Gasoline. Also, your
GM dealer has additives that will help correct and
prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines may be available in
your area. General Motors recommends that you use
these gasolines if they comply with the specifications
described earlier. However, E85 (85% ethanol)
and other fuels containing more than 10% ethanol must
not be used in vehicles that were not designed for
those fuels.

Notice: Your vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage would not be covered under
your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to find. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not
be covered by your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors
recommends against the use of such gasolines. Fuels

{CAUTION:
If you spill fuel and then something ignites it,
you could be badly burned. Fuel can spray out
on you if you open the fuel cap too quickly.
This spray can happen if your tank is nearly
full, and is more likely in hot weather. Open
the fuel cap slowly and wait for any hiss noise
to stop. Then unscrew the cap all the way.
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice: If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not fit properly.

Life System
Your vehicle has a computer system that lets you
know when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions, the
mileage at which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
The Engine Oil Life System calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where you change your oil prior to a change engine oil

Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
• When outside temperatures are above 90°F (32°C).
• At high speed for quite a while.
• In heavy traffic — especially in hot weather.
• While pulling a trailer.
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change the fluid and filter at the intervals listed in
page 6-6, and be sure to use the transmission fluid listed
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it is colder than 50°F (10°C), drive the vehicle
in DRIVE (D) until the engine temperature gage
moves and then remains steady for 10 minutes.
How to Check Automatic Transmission
Fluid
Because this operation can be a little difficult, you may
choose to have this done at the dealership service
department.
A cold fluid check can be made after the vehicle has
been sitting for eight hours or more with the engine off,
but this is used only as a reference. Let the engine
run at idle for five minutes if outside temperatures are
50°F (10°C) or more. If it is colder than 50°F (10°C), you
may have to idle the engine longer. Should the fluid
level be low during this cold check, you must check the
fluid hot before adding fluid. Checking the fluid hot
will give you a more accurate reading of the fluid level.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice: Too much or too little fluid can damage
your transmission. Too much can mean that some
of the fluid could come out and fall on hot engine
part or exhaust system parts, starting a fire.
Too little fluid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission fluid.

lever through each gear range, pausing for about
three seconds in each range. Then, position
the shift lever in PARK (P).
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be in the COLD area for
a cold check or in the HOT or cross-hatched
area for a hot check. Be sure to keep the dipstick
pointed down to get an accurate reading.
4. Let the engine run at idle for three minutes or more.
Then, without shutting off the engine, follow these steps:

How to Add Automatic Transmission
Fluid
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL® engine coolant. This coolant is designed
to remain in your vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL® extended life coolant.
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Using a funnel, add fluid down the transmission
dipstick tube only after checking the transmission fluid
while it is hot. A cold check is used only as a reference.
If the fluid level is low, add only enough of the proper
fluid to bring the level up to the HOT area for a hot
check. It does not take much fluid, generally less than
one pint (0.5 L). Do not overfill.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
page 5-24.
A 50/50 mixture of clean, drinkable water and
DEX-COOL® coolant will:
• Give freezing protection down to −34°F (−37°C).
• Give boiling protection up to 265°F (129°C).
• Protect against rust and corrosion.
Notice: Use of the incorrect automatic transmission
fluid may damage your vehicle, and the damages
may not be covered by your warranty. Always

• Help keep the proper engine temperature.
• Let the warning lights and gages work as
they should.
• After adding fluid, recheck the fluid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
Notice: Using coolant other than DEX-COOL® may
cause premature engine, heater core, radiator
and fuel operated heater (FOH) corrosion. In
addition, the engine coolant may require changing
sooner, at 30,000 miles (50 000 km) or 24 months,

Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not be covered by your
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core and
other parts.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL® coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
{CAUTION:
Notice: If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could
damage your vehicle. Use only the proper mixture
of the engine coolant listed in this manual for
the cooling system. See Recommended Fluids and
more information.
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.

If your vehicle has a diesel engine, see “Checking
Coolant” under “Van Models” in the DURAMAX® Diesel
Supplement for information on checking your vehicle’s
coolant.
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
The coolant recovery tank
is located near the center
of the engine
compartment. See Engine
on page 5-12 for more
information on location.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the COLD
FILL mark, or a little higher.
Adding Coolant
Occasionally check the coolant level in the radiator. For
information on how to add coolant to the radiator,

If the overheat warning continues, there is one more
thing you can try. You can add the proper coolant
mixture directly to the radiator, but be sure the cooling
system is cool before you do it.
• Fill your washer fluid tank only three-quarters full
when it is very cold. This allows for expansion if
freezing occurs, which could damage the tank if
it is completely full.
• Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
{CAUTION:
Notice: In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap — even a little — they can come
out at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have
to turn the pressure cap.
{CAUTION:
You can be burned if you spill coolant on hot
components in the engine compartment.
Coolant contains ethylene glycol, and it will
burn if the engine parts are hot enough. Do not
spill coolant on a hot engine or components in
the engine compartment.
When the coolant in the coolant recovery tank is at the

Engine Fan Noise
Power Steering Fluid
Your vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air to cool the engine. In most everyday driving
conditions, the fan is spinning slower and the clutch is
not fully engaged. This improves fuel economy and
reduces fan noise. Under heavy vehicle loading, trailer
towing, and/or high outside temperatures, the fan
speed increases as the clutch more fully engages, so
you may hear an increase in fan noise. This is
normal and should not be mistaken as the transmission
slipping or making extra shifts. It is merely the cooling
system functioning properly. The fan will slow down
when additional cooling is not required and the clutch
partially disengages.
The power steering fluid
reservoir is located in the
engine compartment
on the driver’s side of the
vehicle. See Engine
page 5-12 for reservoir
location.
You may also hear this fan noise when you start the
engine. It will go away as the fan clutch partially
disengages.

The level should be at the COLD FILL mark. If
necessary, add only enough fluid to bring the level up to
the mark.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
To prevent contamination of brake fluid, never check or
fill the power steering reservoir with the brake master
cylinder cover off.
What to Use
How to Check Power Steering Fluid
To determine what kind of fluid to use, see
on page 6-13. Always use the proper fluid. Failure to
use the proper fluid can cause leaks and damage hoses
and seals.
To check the power steering fluid, do the following:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with
a clean rag.
4. Replace the cap and completely tighten it.
5. Then remove the cap again and look at the fluid
level on the dipstick.

Notice:
Windshield Washer Fluid
What to Use
• When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
• Do not mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts of
the washer system. Also, water does not clean as
well as washer fluid.
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will
be operating your vehicle in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.
• Fill your washer fluid tank only three-quarters full
when it is very cold. This allows for expansion if
freezing occurs, which could damage the tank if
it is completely full.
Adding Washer Fluid
Open the cap with the
washer symbol on it. Add
washer fluid until the
tank is full. See Engine
page 5-12 for reservoir
location.
• Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.

So, it is not a good idea to top off your brake fluid.
Adding brake fluid will not correct a leak. If you add fluid
when your linings are worn, then you will have too
much fluid when you get new brake linings. You should
add or remove brake fluid, as necessary, only when
work is done on the brake hydraulic system.
Brakes
Brake Fluid
Your brake master cylinder
reservoir is filled with
DOT-3 brake fluid. See
the location of the
{CAUTION:
reservoir.
If you have too much brake fluid, it can spill on
the engine and/or fuel operated heater parts, if
equipped. If your vehicle has a diesel engine
and a fuel operated heater, see “Fuel Operated
Heater (FOH)” in the diesel engine supplement.
The fluid will burn if the engine is hot enough.
You or others could be burned, and your
vehicle could be damaged. Add brake fluid
only when work is done on the brake hydraulic
system. See “Checking Brake Fluid” in this
section.
There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the
brake fluid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the fluid level goes back up. The other reason is
that fluid is leaking out of the brake system. If it is, you
should have your brake system fixed, since a leak
means that sooner or later your brakes will not work
well, or will not work at all.
Refer to the Maintenance Schedule to determine when
to check your brake fluid. See Scheduled Maintenance

Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from entering the reservoir.
Checking Brake Fluid
You can check the brake fluid without taking off the cap.
Look at the brake fluid
reservoir. The fluid level
should be above MIN. If it
is not, have your brake
system checked to
{CAUTION:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
see if there is a leak.
Notice:
• Using the wrong fluid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system parts so
badly that they will have to be replaced. Do not
let someone put in the wrong kind of fluid.
After work is done on the brake hydraulic system,
make sure the level is above the MIN but not over
the MAX mark.
What to Add
• If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can be damaged. Be
careful not to spill brake fluid on your vehicle. If
you do, wash it off immediately. See Washing
When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container
only. See Recommended Fluids and Lubricants

Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to GM torque specifications.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving, except when you are pushing on the
brake pedal firmly.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
{CAUTION:
Brake Adjustment
The brake wear warning sound means that soon
your brakes will not work well. That could lead
to an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Every time you make a brake stop, your disc brakes
adjust for wear.
Notice: Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.

Warning: Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm. Wash hands
after handling.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together
if the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system —for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
GM replacement parts. If you do not, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you

Notice: If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
Jump Starting
If your vehicle’s battery has run down, you may want to
use another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
• They contain acid that can burn you.
• They contain gas that can explode
or ignite.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
• They contain enough electricity to
burn you.
Notice: If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
If you do not follow these steps exactly, some or
all of these things can hurt you.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
Notice: Ignoring these steps could result in costly
damage to your vehicle that would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.

4. Open the hoods and locate the positive (+) and
negative (−) terminal locations of the other vehicle.
{CAUTION:
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−) jump
starting terminal. You should always use these
remote terminals instead of the terminals on
the battery.
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
flashlight if you need more light.
The remote positive (+) terminal is located behind a
red plastic cover near the engine accessory drive
bracket on the driver’s side of the engine
compartment, below the alternator. To uncover
the remote positive (+) terminal, open the red
plastic cover.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has filler
caps, be sure the right amount of fluid is there.
If it is low, add water to take care of that first.
If you do not, explosive gas could be present.
The remote negative (−) terminal is located on the
engine drive bracket on all V8 engines and is
marked GND (Ground).
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, flush the place
with water and get medical help immediately.
On V6 engines the remote negative (−) terminal is
located on a tab attached to the engine accessory
drive bracket and is marked GND (Ground).

How to Check
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
after 100, 1,000 and 6,000 miles (160, 1 600 and
10 000 km) of driving. For proper wheel nut tightening
information, see “Removing the Flat Tire and Installing
the Spare Tire” later in this section, under Changing
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Check the tire’s inflation pressure when the tires are
cold. Cold means your vehicle has been sitting for
at least three hours or driven no more than 1 mile
(1.6 km).
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically.
page 6-4.
Remove the valve cap from the tire valve stem. Press
the tire gage firmly onto the valve to get a pressure
measurement. If the cold tire inflation pressure matches
the recommended pressure on the tire and loading
information label, no further adjustment is necessary. If
the pressure is low, add air until you reach the
recommended amount.
If you overfill the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
{CAUTION:
If you operate your vehicle with a tire that is
badly underinflated, the tire can overheat. An
overheated tire can lose air suddenly or catch
fire. You or others could be injured. Be sure all
tires (including the spare) are properly inflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See When It Is Time
on page 5-67 for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire. If it moves,
use the ratchet/wheel wrench to tighten the cable. See
Single Rear Wheels
If your vehicle has single rear wheels, always use the
correct rotation patterns shown here when rotating your
vehicle’s tires. Do not include the spare tire in the tire
rotation, if the spare tire/wheel assembly does not match
your vehicle’s road tires and wheels in size and type.
If your vehicle has dual rear wheels, also see Dual Tire
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See Scheduled Maintenance

{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get all

Dual Rear Wheels
If your vehicle has dual rear wheels, always use one of
the correct rotation patterns shown here when rotating
your tires.
When you install dual wheels, be sure that vent holes in
the inner and outer wheels on each side are lined up.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire and

Buying New Tires
GM has developed and matched specific tires for your
vehicle. The original equipment tires installed on
your vehicle, when it was new, were designed to meet
General Motors Tire Performance Criteria Specification
(TPC spec) system rating. If you need replacement
tires, GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to give the
same performance and vehicle safety, during normal
use, as the original tires.

GM’s exclusive TPC Spec system considers over a
dozen critical specifications that impact the overall
performance of your vehicle, including brake system
performance, ride and handling, traction control, and tire
pressure monitoring performance. GM’s TPC Spec
number is molded onto the tire’s sidewall by the
tire manufacturer. If the tires have an all-season tread
design, the TPC spec number will be followed by a MS,
page 5-53 for additional information.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
If you must replace your vehicle’s tires with those that
do not have a TPC Spec number, make sure they
are the same size, load range, speed rating, and
construction type (radial and bias-belted tires) as your
vehicle’s original tires.
{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes,
brands, or types (radial and bias-belted tires)
the vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes, brands, or types may also cause
damage to your vehicle. Be sure to use the
correct size, brand, and type of tires on your
vehicle’s wheels.
Your vehicle’s original equipment tires are listed on the
Tire and Loading Information Label. This label is
attached to the vehicle’s center pillar (B-pillar). See

Different Size Tires and Wheels
Uniform Tire Quality Grading
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability and
resistance to rollover. Additionally, if your vehicle
has electronic systems such as, antilock brakes; traction
control; and electronic stability control, the performance
of these systems can be affected.
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
{CAUTION:
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not
recommended for those wheels are selected.
You may increase the chance that you will
crash and suffer serious injury. Only use GM
specific wheel and tire systems developed for
your vehicle, and have them properly installed
by a GM certified technician.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

Treadwear
Temperature – A, B, C
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.

If you need to replace any of your wheels, wheel bolts or
wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments to
wheel alignment and tire balancing will not be necessary
on a regular basis. However, if you notice unusual tire
wear or your vehicle pulling to one side or the other, the
alignment may need to be checked. If you notice your
vehicle vibrating when driving on a smooth road, your
tires and wheels may need to be rebalanced. See your
dealer for proper diagnosis.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts and wheel nuts for replacement.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer if any of these conditions exist.
Notice: The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted
the same way as the one it replaces.
Whenever a wheel, wheel bolt or wheel nut is replaced
on a dual wheel setup, check the wheel nut torque
after 100, 1,000 and 6,000 miles (160, 1 600 and
10 000 km) of driving. For proper torque, see “Wheel
Nut Torque” under Capacities and Specifications

Tire Chains
Used Replacement Wheels
{CAUTION:
{CAUTION:
If your vehicle has dual wheels or P235/75R16,
P245/75R16 or LT245/75R16 size tires, do not
use tire chains. They can damage your vehicle
because there is not enough clearance. Tire
chains used on a vehicle without the proper
amount of clearance can cause damage to the
brakes, suspension, or other vehicle parts. The
area damaged by the tire chains could cause
you to lose control of your vehicle and you or
others may be injured in a crash.
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has been
used or how far it has been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it is contacting your vehicle, and do
not spin the vehicle’s wheels.
If you do find traction devices that will fit,
install them on the rear tires.

A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you would
use in a skid. In any rear blowout remove your foot from
the accelerator pedal. Get the vehicle under control
by steering the way you want the vehicle to go. It may
be very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.
P235/75R16, P245/75R16 or LT245/75R16, use tire
chains only where legal and only when you
must. Use chains that are the proper size for your
tires. Install them on the tires of the rear axle. Do not
use chains on the tires of the front axle. Tighten
them as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues, slow down until
it stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.
{CAUTION:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without
the appropriate safety equipment and training.
The jack provided with your vehicle is
designed only for changing a flat tire. If it is
used for anything else, you or others could be
badly injured or killed if the vehicle slips off
the jack. Use the jack provided with your
vehicle only for changing a flat tire.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,
especially if you maintain your vehicle’s tires properly.
If air goes out of a tire, it is much more likely to leak out
slowly. But if you should ever have a blowout, here
are a few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
If a tire goes flat, the next part shows how to use the
jacking equipment to change a flat tire safely.

Changing a Flat Tire
CAUTION: (Continued)
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your vehicle’s
hazard warning flashers. See Hazard Warning Flashers
on page 3-5 for more information.
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
When your vehicle has a flat tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).

Spare Tire
Your vehicle, when new, had a fully inflated spare tire.
A spare tire may lose air over time, so check its
inflation pressure regularly. See Inflation - Tire Pressure
for information regarding proper tire inflation and loading
your vehicle. For instructions on how to remove,
install or store a spare tire, see Removing the Flat Tire
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inflated. Have the damaged or flat road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
Your vehicle may have a different size spare tire than
the road tires — those originally installed on your
vehicle. This spare tire was developed for use on your
vehicle, so it’s all right to drive on it.
7. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves,
use the ratchet to tighten the cable.
You will hear two clicks when the tire is up
all the way.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type, do not include the spare in the tire rotation.
8. Return the jacking equipment to the proper location.
Secure the items and replace the jack cover.

Appearance Care
Cleaning the Inside of Your Vehicle
vehicle, use only a soft cloth and glass cleaner.
Your vehicle’s interior will continue to look its best if
it is cleaned often. Although not always visible, dust and
dirt can accumulate on your upholstery. Dirt can
damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible. Your
vehicle’s interior may experience extremes of heat
that could cause stains to set rapidly.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space. Before
using cleaners, read and adhere to all safety
instructions on the label. While cleaning your vehicle’s
interior, maintain adequate ventilation by opening
your vehicle’s doors and windows.
Dust may be removed from small buttons and knobs
using a small brush with soft bristles.
Your GM dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you can
also obtain a product from your GM dealer to remove
odors from your vehicle’s upholstery.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
Do not clean your vehicle using the following cleaners
or techniques:
When cleaning your vehicle’s interior, only use cleaners
specifically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
• Never use a knife or any other sharp object to
remove a soil from any interior surface.
• Never use a stiff brush. It can cause damage to
your vehicle’s interior surfaces.
• Never apply heavy pressure or rub aggressively
with a cleaning cloth. Use of heavy pressure
can damage your interior and does not improve the
effectiveness of soil removal.
5-84
Download from Www.Somanuals.com. All Manuals Search And Download.
To clean, use the following instructions:
• Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with degreasers.
Using too much soap will leave a residue that
leaves streaks and attracts dirt. For liquid cleaners,
about 20 drops per gallon (3.78 L) of water is a
good guide.
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.
• Do not heavily saturate your upholstery while
cleaning.
4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
• Damage to your vehicle’s interior may result from
the use of many organic solvents such as naptha,
alcohol, etc.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.
Fabric/Carpet
If any of the soil remains, a commercial fabric cleaner or
spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test a
small hidden area for colorfastness first. If the locally
cleaned area gives any impression that a ring formation
may result, clean the entire surface.
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only
be used on floor carpet and carpeted floor mats. For
soils, always try to remove them first with plain water or
club soda. Before cleaning, gently remove as much
of the soil as possible using one of the following
techniques:
After the cleaning process has been completed, a paper
towel can be used to blot excess moisture from the
fabric or carpet.
• For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the
paper towel until no more can be removed.
• For solid dry soils: remove as much as possible
and then vacuum.

Instrument Panel, Vinyl, and Other
Plastic Surfaces
Care of Safety Belts
Keep belts clean and dry.
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a clean soft cloth dampened with a mild soap solution
can be used to gently remove dust and dirt. Never use
spot lifters or removers on plastic surfaces. Many
commercial cleaners and coatings that are sold to
preserve and protect soft plastic surfaces may
permanently change the appearance and feel of your
interior and are not recommended. Do not use silicone
or wax-based products, or those containing organic
solvents to clean your vehicle’s interior because
they can alter the appearance by increasing the gloss in
a non-uniform manner.
{CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.
Weatherstrips
Some commercial products may increase gloss on your
instrument panel. The increase in gloss may cause
annoying reflections in the windshield and even make it
difficult to see through the windshield under certain
conditions.
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather frequent application may be required.

Washing Your Vehicle
Finish Care
The paint finish on the vehicle provides beauty, depth of
color, gloss retention, and durability.
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint finish. You can get GM-approved cleaning products
from your dealer. See Vehicle Care/Appearance
The best way to preserve the vehicle’s finish is to
keep it clean by washing it often with lukewarm or
cold water.
If your vehicle has a “basecoat/clearcoat” paint finish,
the clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint finish.
Do not wash the vehicle in the direct rays of the sun.
Use a car washing soap. Do not use strong soaps
or chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. GM-approved
cleaning products can be obtained from your dealer. See
not use cleaning agents that are petroleum based,
or that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed to dry on the
surface, or they could stain. Dry the finish with a soft,
clean chamois or an all-cotton towel to avoid surface
scratches and water spotting.
Notice: Machine compounding or aggressive
polishing on a basecoat/clearcoat paint finish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint finish on your vehicle.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc.,
can damage your vehicle’s finish if they remain
on painted surfaces. Wash the vehicle as soon as
possible. If necessary, use non-abrasive cleaners that
are marked safe for painted surfaces to remove
foreign matter.
High pressure car washes may cause water to enter
the vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.

Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a
period of years. You can help to keep the paint finish
looking new by keeping your vehicle garaged or covered
whenever possible.
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap, or other material may be on the blade
or windshield.
Protecting Exterior Bright Metal Parts
Clean the outside of the windshield with a glass
cleaning liquid or powder and water solution. The
windshield is clean if beads do not form when it is rinsed
with water.
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, you may use chrome polish on
chrome or stainless steel trim, if necessary.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by
wiping vigorously with a cloth soaked in full-strength
windshield washer solvent. Then rinse the blade
with water.
Use special care with aluminum trim. To avoid damaging
protective trim, never use auto or chrome polish,
steam or caustic soap to clean aluminum. A coating of
wax, rubbed to high polish, is recommended for all
bright metal parts.
Check the wiper blades and clean them as necessary;
replace blades that look worn.

Notice: If you drive your vehicle through an
automatic car wash that has silicone carbide tire
cleaning brushes, you could damage the aluminum
or chrome-plated wheels. The repairs would not
be covered by your warranty. Never drive a vehicle
equipped with aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
Aluminum Wheels
Notice: If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or cleaners
that contain acid on aluminum or chrome-plated
wheels, you could damage the surface of the
wheel(s). The repairs would not be covered by your
warranty. Use only GM-approved cleaners on
aluminum or chrome-plated wheels.
Do not take the vehicle through an automatic car wash
that has silicone carbide tire cleaning brushes. These
brushes can also damage the surface of these wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.
Tires
Notice: Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by your warranty. Use chrome polish on
chrome wheels only.
To clean the tires, use a stiff brush with tire cleaner.
Notice: Using petroleum-based tire dressing
products on your vehicle may damage the paint
finish and/or tires. When applying a tire dressing,
always wipe off any overspray from all painted
surfaces on your vehicle.
The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because the surface could be damaged. Do not
use chrome polish on aluminum wheels.

At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and debris can collect. Dirt packed in close areas of
the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can
do this for you.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to parts repaired or
replaced to restore corrosion protection.
Original manufacturer replacement parts will provide the
corrosion protection while maintaining the warranty.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage can
take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the
paint surface.
Finish Damage
Any stone chips, fractures or deep scratches in the
finish should be repaired right away. Bare metal
will corrode quickly and may develop into major repair
expense.
Although no defect in the paint job causes this, GM will
repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
Minor chips and scratches can be repaired with touch-up
materials available from your GM dealer. Larger areas
of finish damage can be corrected in your GM
dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, floor pan,
and exhaust system even though they have corrosion
protection.

Windshield Wiper Fuses
Electrical System
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
Although the circuit is protected from electrical overload,
overload due to heavy snow, etc., may cause wiper
linkage damage. Always clear ice and heavy snow from
the windshield before using the windshield wipers. If
the overload is caused by some electrical problem and
not snow, etc., be sure to get it fixed.
Add-On Electrical Equipment
Notice: Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to flicker on and off, or in some cases to remain
off. If this happens, have your headlamp wiring
checked right away.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.

Maintenance Requirements
Maintenance Schedule
Notice: Maintenance intervals, checks, inspections,
replacement parts, and recommended fluids and
lubricants as prescribed in this manual are
necessary to keep your vehicle in good working
condition. Any damage caused by failure to follow
scheduled maintenance may not be covered by
warranty.
Introduction
This maintenance section applies to vehicles with a
gasoline engine. If your vehicle has a diesel engine, see
the maintenance schedule section in the
DURAMAX® Diesel Engine Supplement.
Important: Keep engine oil at the proper level and
change as recommended.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance is
important. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level of
emissions from your vehicle. To help protect our
environment, and to keep your vehicle in good condition,
be sure to maintain your vehicle properly.
Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties. See your
Warranty and Owner Assistance booklet or your dealer

Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do not know
exactly how you will drive it. You may drive very
short distances only a few times a week. Or you may
drive long distances all the time in very hot, dusty
weather. You may use your vehicle in making deliveries.
Or you may drive it to work, to do errands, or in many
other ways.
{CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you
can be seriously injured. Do your own
maintenance work only if you have the
required know-how and the proper tools and
equipment for the job. If you have any doubt,
see your GM Goodwrench® dealer to have a
qualified technician do the work. See Doing
Because of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep your vehicle in good condition,
see your GM Goodwrench® dealer.
This schedule is for vehicles that:
• carry passengers and cargo within recommended
limits. You will find these limits on the tire and
loading information label. See Loading Your Vehicle
on page 4-30.
Some maintenance services can be complex. So,
unless you are technically qualified and have the
necessary equipment, you should have your GM
Goodwrench® dealer do these jobs.
• are driven on reasonable road surfaces within legal
driving limits.

When you go to your GM Goodwrench® dealer for your
service needs, you will know that GM-trained and
supported service technicians will perform the work
using genuine GM parts.
When the change engine oil light comes on, it means that
service is required for your vehicle. Have your vehicle
serviced as soon as possible within the next 600 miles
(1 000 km). It is possible that, if you are driving under the
best conditions, the engine oil life system may not
indicate that vehicle service is necessary for over a year.
However, your engine oil and filter must be changed at
least once a year and at this time the system must be
reset. Your GM Goodwrench® dealer has GM-trained
service technicians who will perform this work using
genuine GM parts and reset the system.
If you want to purchase service information, see Service
should be checked, when to check it, and what you
can easily do to help keep your vehicle in good
condition.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
your vehicle is serviced, make sure these are used.
All parts should be replaced and all necessary repairs
done before you or anyone else drives the vehicle.
We recommend the use of genuine GM parts.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System (Gasoline Engine) on page 5-16
for information on the Engine Oil Life System and
resetting the system.
When the change engine oil light appears, certain
services, checks, and inspections are required.
Required services are described in the following for
“Maintenance I” and “Maintenance II.” Generally,
it is recommended that your first service be
Maintenance I, your second service be Maintenance II,
and that you alternate Maintenance I and Maintenance II
thereafter. However, in some cases, Maintenance II
may be required more often.

Customer Assistance and
Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to
your dealer and to GMC. Normally, any concerns with
the sales transaction or the operation of the vehicle
will be resolved by your dealer’s sales or service
departments. Sometimes, however, despite the best
intentions of all concerned, misunderstandings can
occur. If your concern has not been resolved to your
satisfaction, the following steps should be taken:
We encourage you to call the toll-free number in order
to give your inquiry prompt attention. Please have
the following information available to give the Customer
Assistance Representative:
• Vehicle Identification Number (VIN). This is
available from the vehicle registration or title, or the
plate at the top left of the instrument panel and
visible through the windshield.
STEP ONE: Discuss your concern with a member of
dealership management. Normally, concerns can
be quickly resolved at that level. If the matter has
already been reviewed with the sales, service or parts
manager, contact the owner of the dealership or
the general manager.
• Dealership name and location.
• Vehicle delivery date and present mileage.
When contacting GMC, please remember that your
concern will likely be resolved at a dealer’s facility.
That is why we suggest you follow Step One first if you
have a concern.

BBB Auto Line Program to enforce any additional
rights you may have. Canadian owners refer to your
Warranty and Owner Assistance Information booklet for
information on the Canadian Motor Vehicle Arbitration
Plan (CAMVAP).

Transportation Options
Courtesy Transportation
Warranty service can generally be completed while you
wait. However, if you are unable to wait, GM helps
to minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
To enhance your ownership experience, we and our
participating dealers are proud to offer Courtesy
Transportation, a customer support program for
new vehicles.
The Courtesy Transportation program is offered to
customers in conjunction with the Bumper-to-Bumper
coverage provided by the New Vehicle Limited Warranty.
Several transportation options are available when
warranty repairs are required. This will reduce your
inconvenience during warranty repairs.
Shuttle Service
Participating dealers can provide you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes
one-way or round trip shuttle service to a destination up
to 10 miles (16 km) from the dealership.
Scheduling Service Appointments

If your vehicle requires overnight warranty repairs,
reimbursement of public transportation expenses may
be available, for up to a maximum of five days. In

your dealer can help minimize your inconvenience.
If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related. If it is, please call your dealership, let
them know this, and ask for instructions.
If the dealer requests that you simply drop the vehicle off
for service, you are urged to do so as early in the work
day as possible to allow for the same day repair.

Courtesy Transportation is available only at participating
dealers and all program options, such as shuttle
service, may not be available at every dealer. Please
contact your dealer for specific information about
availability. All Courtesy Transportation arrangements
will be administered by appropriate dealer personnel.
Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
that you obtain if your vehicle is kept for a warranty
repair. Reimbursement will be limited to a maximum
amount per day and must be supported by receipts.
This requires that you sign and complete a rental
agreement and meet state, local and rental vehicle
provider requirements. Requirements vary and
may include minimum age requirements, insurance
coverage, credit card, etc. You are responsible for fuel
usage charges and may also be responsible for
taxes, levies, usage fees, excessive mileage or rental
usage beyond the completion of the repair.
Canadian Vehicles: For warranty repairs during
the Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult
your dealer for details.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at
any time and to resolve all questions of claim eligibility
pursuant to the terms and conditions described
herein at its sole discretion.

Unlike the data recorders on many airplanes, these
on-board systems do not record sounds, such as
conversation of vehicle occupants.
Vehicle Data Collection and Event
Data Recorders
To read this information, special equipment is needed
and access to the vehicle or the device that stores
the data is required. GM will not access information
about a crash event or share it with others other than:
• with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee,
• in response to an official request of police or similar
government office,
• as part of GM’s defense of litigation through the

Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called
event data recorders (EDR).
• as required by law.
In addition, once GM collects or receives data, GM may:
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to
engine speed, brake application, throttle position, vehicle
speed, safety belt usage, airbag readiness, airbag
performance, and the severity of a collision. If your
vehicle is equipped with StabiliTrak®, steering
performance, including yaw rate, steering wheel angle,
and lateral acceleration, is also recorded. This
information has been used to improve vehicle crash
performance and may be used to improve crash
performance of future vehicles and driving safety.
• use the data for GM research needs,
• make it available for research where appropriate
confidentiality is to be maintained and need is
shown, or
• share summary data which is not tied to a specific
vehicle with non-GM organizations for research
purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information
if they have access to the vehicle or the device
that stores the data.

Aftermarket collision parts are also available. These are
made by companies other than GM and may not
have been tested for your vehicle. As a result, these
parts may fit poorly, exhibit premature
durability/corrosion problems, and may not perform
properly in subsequent collisions. Aftermarket parts are
not covered by your GM New Vehicle Limited
Warranty, and any vehicle failure related to such parts
are not covered by that warranty.
Collision Damage Repair
If your vehicle is involved in a collision and it is damaged,
have the damage repaired by a qualified technician using
the proper equipment and quality replacement parts.
Poorly performed collision repairs will diminish your
vehicle’s resale value, and safety performance can be
compromised in subsequent collisions.
Collision Parts
Repair Facility
Genuine GM Collision parts are new parts made with the
same materials and construction methods as the parts
with which your vehicle was originally built. Genuine GM
Collision parts are your best choice to assure that your
vehicle’s designed appearance, durability and safety are
preserved. The use of Genuine GM parts can help
maintain your GM New Vehicle Warranty.
GM also recommends that you choose a collision repair
facility that meets your needs before you ever need
collision repairs. Your GM dealer may have a collision
repair center with GM-trained technicians and state
of the art equipment, or be able to recommend a
collision repair center that has GM-trained technicians
and comparable equipment.
Recycled original equipment parts may also be used for
repair. These parts are typically removed from vehicles
that were total losses in prior accidents. In most
cases, the parts being recycled are from undamaged
sections of the vehicle. A recycled original equipment
GM part, may be an acceptable choice to maintain your
vehicle’s originally designed appearance and safety
performance, however, the history of these parts is not
known. Such parts are not covered by your GM New
Vehicle Limited Warranty, and any related failures
are not covered by that warranty.
Insuring Your Vehicle
Protect your investment in your GM vehicle with
comprehensive and collision insurance coverage. There
are significant differences in the quality of coverage
afforded by various insurance policy terms. Many
insurance policies provide reduced protection to your GM
vehicle by limiting compensation for damage repairs by
using aftermarket collision parts. Some insurance
companies will not specify aftermarket collision parts.
7-11
Download from Www.Somanuals.com. All Manuals Search And Download.
When purchasing insurance, we recommend that you
assure your vehicle will be repaired with GM original
equipment collision parts. If such insurance coverage is
not available from your current insurance carrier,
consider switching to another insurance carrier.
• If you need roadside assistance, call GM Roadside
page 7-6 for more information.
• If your vehicle cannot be driven, know where the
towing service will be taking it. Get a card from the
tow truck operator or write down the driver’s name,
the service’s name, and the phone number.
• Remove any valuables from your vehicle before it is
towed away. Make sure this includes your insurance
information and registration if you keep these items
in your vehicle.
If your vehicle is leased, the leasing company may
require you to have insurance that assures repairs with
Genuine GM Original Equipment Manufacturer (OEM)
parts or Genuine Manufacturer replacement parts. Read
your lease carefully, as you may be charged at the
end of your lease for poor quality repairs.
• Gather the important information you will need from
the other driver. Things like name, address, phone
number, driver’s license number, vehicle license
plate, vehicle make, model and model year, Vehicle
Identification Number (VIN), insurance company and
policy number, and a general description of the
damage to the other vehicle.
If an Accident Occurs
Here is what to do if you are involved in an accident.
• Try to relax and then check to make sure you are all
right. If you are uninjured, make sure that no one else
in your vehicle, or the other vehicle, is injured.
• If there has been an injury, call 911 for help. Do not
leave the scene of an accident until all matters have
been taken care of. Move your vehicle only if its
position puts you in danger or you are instructed to
move it by a police officer.
• Give only the necessary and requested information
to police and other parties involved in the accident.
Do not discuss your personal condition, mental frame
of mind, or anything unrelated to the accident. This
will help guard against post-accident legal action.
• If possible, call your insurance company from the
scene of the accident. They will walk you through the
information they will need. If they ask for a police
report, phone or go to the police department
headquarters the next day and you can get a copy of
the report for a nominal fee. In some states with “no
fault” insurance laws, a report may not be necessary.
This is especially true if there are no injuries and both
vehicles are driveable.

Remember if your vehicle is leased you may be
obligated to have the vehicle repaired with Genuine
GM parts, even if your insurance coverage does not pay
the full cost.
• Choose a reputable collision repair facility for your
vehicle. Whether you select a GM dealer or a private
collision repair facility to fix the damage, make sure
you are comfortable with them. Remember, you
will have to feel comfortable with their work for a
long time.
If another party’s insurance company is paying for the
repairs, you are not obligated to accept a repair
valuation based on that insurance company’s collision
policy repair limits, as you have no contractual limits with
that company. In such cases, you can have control of
the repair and parts choices as long as cost stays within
reasonable limits.
• Once you have an estimate, read it carefully and
make sure you understand what work will be
performed on your vehicle. If you have a question,
ask for an explanation. Reputable shops welcome
this opportunity.
Managing the Vehicle Damage Repair
Process
Reporting Safety Defects
In the event that your vehicle requires damage repairs,
GM recommends that you take an active role in its
repair. If you have a pre-determined repair facility of
choice, take your vehicle there, or have it towed there.
Specify to the facility that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled original GM parts.
Remember, recycled parts will not be covered by your
GM vehicle warranty.
Reporting Safety Defects to the
United States Government
If you believe that your vehicle has a defect which could
cause a crash or could cause injury or death, you
should immediately inform the National Highway Traffic
Safety Administration (NHTSA), in addition to notifying
General Motors.
If NHTSA receives similar complaints, it may open an
investigation, and if it finds that a safety defect exists in a
group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved
in individual problems between you, your dealer, or
General Motors.
Insurance pays the bill for the repair, but you must live
with the repair. Depending on your policy limits, your
insurance company may initially value the repair using
aftermarket parts. Discuss this with your repair
professional, and insist on Genuine GM parts.
