changes in design and equipment. Therefore, information, illustrations and descriptions in this Operator’s Manual

Warning!  
This SportUtilityVehicleis designed forbothon-road and off-road use. Itcan go places and perform tasks for  
which conventional 2-wheel drive passenger cars were not intended. This vehicle will handle and maneuver  
differently from conventional passenger cars in driving conditions which may occur on streets, highways and  
off-road use.  
This vehicle has a higher ground clearance and a higher center of gravity than many passenger cars. As with  
other vehicles of this type, if you make sharp turns at excessive speeds or abrupt maneuvers, the vehicle may  
roll over or may go out of control and crash. Utility vehicles have a significantly higher rollover rate than  
other types of vehicles. Failure to operate this vehicle safely may result in an accident, rollover of the vehicle,  
and severe or fatal injury.  
Before you start to drive this vehicle, read the Operator’s Manual. Take time to become familiar with the  
driving characteristics of this vehicle. Be sure you are familiar with all vehicle controls. Learn how your  
vehicle handles on different road surfaces. Do not attempt sharp turns at excessive speeds or abrupt  
maneuvers or other unsafe driving actions that can cause loss of vehicle control. When driving off-road or  
working the vehicle, do not overload it. And, always wear your seat belts at all times. In a rollover crash, an  
unbelted person is significantly more likely to die than a person wearing a seat belt.

Front seat adjustment  
Warning!  
When leaving the vehicle always remove the  
electronic key from the starter switch, and lock  
your vehicle.  
The power seats can also be operated with the  
driver’s or front passenger door open. Do not leave  
children unattended in the vehicle, or with access  
to an unlocked vehicle. Unsupervised use of vehicle  
equipment may cause serious personal injury.  
Do not adjust the driver’s seat while driving.  
Adjusting the seat while driving could cause the  
driver to lose control of the vehicle.  
Never ride in a moving vehicle with the seat back  
reclined. Sitting in an excessively reclined position  
can be dangerous. You could slide under the seat  
belt in a collision. If you slide under it, the belt  
would apply force at the abdomen or neck. That  
could cause serious or fatal injuries. The seat back  
and seat belts provide the best restraint when the  
wearer is in an upright position and belts are  
properly positioned on the body.  
To operate the front power seat adjustment switches,  
turn the electronic key in starter switch to position 1  
or 2 (with respective front door open, the power seats  
can also be operated with the electronic key removed or  
in starter switch position 0).  
Note:  
Never place hands under seat or near any moving  
parts while a seat is being adjusted.  
If the passenger side seat backrest is set to a full upright  
position and the passenger seat is moved fully forward,  
the cup holder next to the armrest must be removed  
(page 166) and the cup holder in the passenger footwell  
(page 167) must be folded closed.

Important!  
Prior to operating the vehicle, the driver should check  
and adjust if necessary the seat height, seat position  
fore and aft, and backrest angle to insure adequate  
control, reach and comfort. The head restraint should  
also be adjusted for proper height. See also airbag  
section for proper seat positioning.  
Children 12 years old and under must never ride in  
the front seat, except in a Mercedes-Benz  
authorized BabySmartTM compatible child seat,  
which operates with the BabySmartTM system  
installed in the vehicle to deactivate the passenger  
side front airbag when it is properly installed.  
Otherwise they will be struck by the airbag when it  
inflates in a crash. If this happens, serious or fatal  
injury can result.  
In addition, also adjust the steering wheel to ensure  
adequate control, reach, operation and comfort. Both the  
inside and outside rear view mirrors should be adjusted  
for adequate rearward vision.  
According to accident statistics, children are safer  
when properly restrained in the rear seating  
positions than in the front seating positions.  
Infants and small children must ride in back seats  
and be seated in an appropriate infant or child  
restraint system, which is properly secured with  
the vehicle’s seat belt, fully in accordance with the  
child seat manufacturer’s instructions.  
Fasten seat belts. Infants and small children should be  
seated in a properly secured restraint system that  
complies with U.S. Federal Motor Vehicle Safety  
Standard 213 and Canadian Motor Vehicle Safety  
Standard 213.  
All seat, head restraint, steering wheel, and rear view  
mirror adjustments as well as fastening of seat belts  
should be done before the vehicle is put into motion.  
A child’s risk of serious or fatal injuries is  
significantly increased if the child restraints are  
not properly secured in the vehicle and the child is  
not properly secured in the child restraint.

Seat belts and integrated restraint system  
Your vehicle is equipped with seat belts for all seats,  
emergency tensioning retractors for front and second  
row outboard seat belts, and single front airbags. Their  
protective functions are designed to complement one  
another.  
Children 12 years old and under must never ride in  
the front seat, except in a Mercedes-Benz  
authorized BabySmartTM compatible child seat,  
which operates with the BabySmartTM system  
installed in the vehicle to deactivate the passenger  
side front airbag when it is properly installed.  
Otherwise they will be struck by the airbag when it  
inflates in a crash. If this happens, serious or fatal  
injury will result.  
Seat belts  
Important!  
According to accident statistics, children are safer  
when properly restrained in the rear seating  
positions than in the front seating positions.  
Infants and small children must ride in back seats  
and be seated in an appropriate infant or child  
restraint system, which is properly secured with  
the vehicle’s seat belt, fully in accordance with the  
child seat manufacturer’s instructions.  
Laws in most states and all Canadian provinces require  
seat belt use.  
All states and provinces require use of child restraints  
that comply with U.S. Federal Motor Vehicle Safety  
Standard 213 and Canadian Motor Vehicle Safety  
Standard 213.  
A child’s risk of serious or fatal injuries is  
significantly increased if the child restraints are  
not properly secured in the vehicle and the child is  
not properly secured in the child restraint.  
All child restraint systems are designed to be secured in  
vehicle seats by lap belts or the lap belt portion of a lap-  
shoulder belt.  
For your safety and that of your passengers we strongly  
recommend their use.

Warning!  
Warning!  
Never ride in a moving vehicle with the backrest  
reclined. Sitting in an excessively reclined position  
can be dangerous. You could slide under the seat  
belt in a collision. If you slide under it, the belt  
would apply force at the abdomen or neck. That  
could cause serious or even fatal injuries. The  
backrest and seat belt provide the best restraint  
when the wearer is in an upright position and the  
belt is properly positioned on the body.  
Failure to wear and properly fasten and position  
your seat belt greatly increases your risk of  
injuries and their likely severity in an accident.  
You and your passengers should always wear seat  
belts.  
If you are ever in an accident, your injuries can be  
considerably more severe without your seat belt  
properly buckled. Without your seat belt buckled,  
you are much more likely to hit the interior of the  
vehicle or be ejected from it. You can be seriously  
injured or killed.  
Note:  
For cleaning and care of the seat belts, see page 354.  
In the same crash, the possibility for injury or  
death is lessened if you are wearing your seat belt.  
Seat belt nonusage warning system  
Warning!  
After starting the engine, a warning sounds a short time  
and the seat belt warning lamp < remains  
illuminated if the driver’s seat belt is not fastened.  
Never let more people ride in the vehicle than there  
are seat belts available. Be sure everyone riding in  
the vehicle is correctly restrained with a separate  
seat belt.

USE SEAT BELTS PROPERLY.  
• Seat belts can only work when used properly.  
Never wear seat belts in any other way than as  
described in this section, as that could result  
in serious injuries in case of an accident.  
• Each occupant should wear their seat belt at all  
times, because seat belts help reduce the  
likelihood of and potential severity of injuries  
in accidents, including rollovers. The  
integrated restraint system includes “SRS”  
(driver airbag and front passenger airbag) and  
“ETR” (seat belt emergency tensioning  
retractors for the driver’s seat, passenger’s seat  
and rear outboard passenger seats). The  
system is designed to enhance the protection  
offered to properly belted occupants in certain  
frontal (front airbags) impacts which exceed  
preset deployment thresholds.  
Operation of seat belts  
The inertia reel stops the belt from unwinding during  
sudden vehicle stops or when quickly pulling on the  
belt. The locking function of the reel may be checked by  
quickly pulling out the belt.  
Unfastening of seat belts  
Push the release button (3) in the belt buckle (2).  
Allow the retractor to completely rewind the seat belt by  
guiding the latch plate (1).  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
• Never wear the shoulder belt under your arm,  
against your neck or off your shoulder. In a  
crash, your body would move too far forward.  
That would increase the chance of head and  
neck injuries. The belt would also apply too  
much force to the ribs or abdomen, which  
could severely injure internal organs such as  
your liver or spleen.  
• Each seat belt should never be used for more  
than one person at a time. Do not fasten a seat  
belt around a person and another person or  
other objects.  
• Belts should not be worn twisted. In a crash,  
you wouldn’t have the full width of the belt to  
manage impact forces. The twisted belt against  
your body could cause injuries.  
• Never wear belts over rigid or breakable  
objects in or on your clothing, such as  
eyeglasses, pens, keys etc., as these might  
cause injuries.  
• Pregnant women should also use a lap-  
shoulder belt. The lap belt portion should be  
positioned as low as possible on the hips to  
avoid any possible pressure on the abdomen.  
• Position the lap belt as low as possible on your  
hips and not across the abdomen. If the belt is  
positioned across your abdomen, it could cause  
serious injuries in a crash.  
• Never place your feet on the instrument panel  
or on the seat. Always keep both feet on the  
floor in front of the seat.

Warning!  
USE CHILD RESTRAINTS PROPERLY.  
A child’s risk of serious or fatal injuries is  
significantly increased if the child restraints are  
not properly secured in the vehicle and the child is  
not properly secured in the child restraint.  
Children 12 years old and under must never ride in  
the front seat, except in a Mercedes-Benz  
authorized BabySmartTM compatible child seat,  
which operates with the BabySmartTM system  
installed in the vehicle to deactivate the passenger  
front airbag when it is properly installed.  
Otherwise they will be struck by the airbag when it  
inflates in a crash. If this happens, serious or fatal  
injury will result.  
Children too big for child restraint systems must  
ride in back seats using regular seat belts. Position  
shoulder belt across chest and shoulder, not face or  
neck. A booster seat may be necessary to achieve  
proper belt positioning.  
According to accident statistics, children are safer  
when properly restrained in the rear seating  
positions than in the front seating positions.  
Infants and small children must ride in back seats  
and be seated in an appropriate infant or child  
restraint system, which is properly secured with  
the vehicle’s seat belt, fully in accordance with the  
child seat manufacturer’s instructions.

BabySmartTM airbag deactivation system  
Warning!  
Special BabySmartTM compatible child seats, designed  
for use with the Mercedes-Benz system and available at  
any authorized Mercedes-Benz Light Truck Center are  
required for use with the BabySmartTM airbag  
The BabySmartTM airbag deactivation system will  
ONLY work with a special child seat designed to  
operate with it. It will not work with child seats  
which are not BabySmartTM compatible.  
deactivation system. With the special child seat properly  
installed, the passenger front airbag will not deploy.  
Never place anything between seat cushion and  
child seat (e.g. pillow), since it reduces the  
effectiveness of the deactivation system. The  
bottom of the child seat must make full contact  
with the passenger seat cushion. An incorrectly  
mounted child seat could cause injuries to the  
child in case of an accident instead of protecting  
the child.  
The ü indicator lamp located in the center console  
will be illuminated, except with electronic key removed  
or in starter switch position 0.  
Self-test BabySmartTM without special child seat  
installed  
Follow the manufacturer’s instructions for  
installation of special child seats.  
After turning electronic key in starter switch to  
position 1 or 2, the ü indicator lamp located in the  
center console comes on for approximately 6 seconds  
and then extinguishes.  
The passenger front airbag will not deploy only if  
the ü indicator lamp remains illuminated.  
Please be sure to check the indicator every time  
you use the special system child seat. Should the  
light go out while the restraint is installed, please  
check installation. If the light remains out, do not  
use the BabySmartTM restraint to transport children  
on the front passenger seat until the system has  
been repaired.  
If the indicator lamp should not come on or is  
continuously lit, the system is not functioning. You must  
see an authorized Mercedes-Benz Light Truck Center  
before seating any child on the front passenger seat. See  
page 271 for notes on the ü indicator lamp.

Supplemental restraint system (SRS)  
Seat belt not fastened  
Front seats:  
Airbags are intended as a supplement to seat belts.  
Airbags alone cannot protect as well as airbags plus  
seat belts in impacts for which the airbags were  
designed to operate, and do not afford any protection  
whatsoever in crashes for which the airbags are not  
designed to deploy.  
first threshold exceeded:  
airbag activates, but not ETR  
Rear outer seats:  
first threshold exceeded:  
The SRS uses two crash severity levels (thresholds) to  
activate either the Emergency Tensioning Retractor  
(ETR) or front airbag or both. Activation depends on the  
direction and severity of the impact exceeding the  
preset thresholds and whether the seat belt is fastened.  
ETR activates  
Notes:  
Driver, front passenger and rear outer seat systems  
operate independently of each other.  
Heavy objects on the front passenger seat can appear to  
the “SRS” to indicate the presence of an occupant in  
that seat which causes the passenger front airbag to  
deploy in a crash exceeding the appropriate threshold.  
Seat belt fastened  
first threshold exceeded: ETR activates  
second threshold exceeded: airbag also activates

Emergency tensioning retractor (ETR)  
Note:  
The emergency tensioning retractors for the driver and  
front passenger seats will only deploy if the front seat  
belts are buckled.  
The seat belts for the front seats and outboard  
passenger seats are equipped with emergency  
tensioning retractors. These tensioning retractors are  
located in each seat belt buckle and become  
operationally ready with the key in starter switch  
position 1 or 2.  
The rear center automatic two point seat belt is not  
equipped with an emergency tensioning retractor.  
The emergency tensioning retractors are designed to  
activate only when the seat belts are fastened during  
frontal impacts exceeding the first threshold of the SRS  
and in rear impacts exceeding a preset severity level.  
They remove slack from the belts in such a way that the  
seat belts fit more snugly against the body restricting its  
forward movement as much as possible.  
In cases of other frontal impacts, angled impacts, roll-  
overs, certain side impacts, or other accidents without  
sufficient frontal or rear impact forces, the emergency  
tensioning retractors will not be activated. The driver  
and passengers will then be protected by the fastened  
seat belts and inertia reel in the usual manner.  
For seat belt and emergency tensioning retractor see  
page 71.

1 Driver airbag  
2 Front passenger airbag  
The most effective occupant restraint system yet  
developed for use in production vehicles is the seat belt.  
In some cases, however, the protective effect of a seat  
belt can be further enhanced by an airbag.  
The passenger front airbag is located in the dashboard  
ahead of the front passenger.  
In conjunction with wearing the seat belts, the driver  
and front passenger airbags can provide increased  
protection for the driver and front passenger in certain  
frontal impacts exceeding preset thresholds.  
The driver airbag is located in the steering wheel hub.

Important!  
In the operational mode, after the indicator lamp has  
gone out following the initial check, interruptions or  
short circuits in the airbag ignition circuit and in the  
driver and front passenger seat belt buckle harnesses,  
and low voltage in the entire system are detected and  
indicated.  
The operational readiness of the airbag system is  
verified by the indicator lamp “SRS” in the instrument  
cluster when turning the key in starter switch to  
position 1 or 2. If no fault is detected, the lamp will go  
out after approximately 5 seconds; after the lamp goes  
out, the system continues to monitor the components  
and circuitry of the airbag system and will indicate a  
malfunction by coming on again. If the lamp does not  
come on at all or if it fails to extinguish after  
Warning!  
In the event a malfunction of the “SRS” is indicated  
as outlined above, the “SRS” may not be  
operational. For your safety, we strongly  
recommend that you visit an authorized  
approximately 5 seconds or if it comes on thereafter,  
a malfunction in the system has been detected.  
Mercedes-Benz Light Truck Center immediately to  
have the system checked; otherwise the “SRS” may  
not be activated when needed in an accident, which  
could result in serious or fatal injury, or it might  
deploy unexpectedly and unnecessarily which  
could also result in injury.  
The following system components are monitored or  
undergo a self-check: crash-sensor(s), airbag ignition  
circuits, front seat belt buckle, emergency tensioning  
retractors, seat sensor.  
Initially, when the key is turned from starter switch  
position 0 to positions 1 or 2, malfunctions in the  
crash-sensor are detected and indicated (the “SRS”  
indicator lamp stays on longer than 5 seconds or does  
not come on).  
Have the system checked at your authorized  
Mercedes-Benz Light Truck Center immediately.

Front airbags  
The driver and front passenger front airbags are  
designed to activate only in certain frontal impacts  
exceeding a preset threshold.  
Airbags are designed to activate only in certain  
frontal (front airbags) impacts which exceed preset  
thresholds.  
The front passenger airbag deploys only if the front  
passenger seat is occupied and the ü indicator lamp  
in the instrument cluster is not illuminated, see  
page 271.  
Only during these types of impacts, if of sufficient  
severity to meet the deployment thresholds, will  
they provide their supplemental protection.  
The driver and passenger should always wear their  
seat belts, otherwise it is not possible for the airbags  
to provide their intended supplemental protection.  
Note:  
Heavy objects on the front passenger seat can appear to  
the “SRS” to indicate the presence of an occupant in  
that seat which causes the passenger front airbag to  
deploy in a crash exceeding the appropriate threshold.  
In cases of other frontal impacts, angled impacts,  
roll-overs, other side impacts, rear collisions, or  
other accidents in which the airbags are not  
designed to deploy, the airbags will not be activated.  
The driver and passenger will then be protected by  
the fastened seat belts.  
We caution you not to rely on the presence of the  
airbags in order to avoid wearing your seat belt.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Your vehicle was originally equipped with airbags  
which are designed to activate in certain impacts  
exceeding a preset threshold to reduce the potential  
and severity of injury. It is important to your safety  
and that of your passenger that you replace deployed  
airbags and repair any malfunctioning airbags to  
ensure the vehicle will continue to provide crash  
protection for occupants.  
Warning!  
Airbags are designed to reduce the potential of  
injury in certain frontal (front airbags) impacts,  
which may cause significant injuries, however, no  
system available today can totally eliminate  
injuries and fatalities.  
The activation of the “SRS” temporarily releases a  
small amount of dust from the airbags. This dust,  
however, is neither injurious to your health, nor  
does it indicate a fire in the vehicle. The dust might  
cause some temporary breathing difficulty for  
people with asthma or other breathing trouble. To  
avoid this, you may wish to get out of the vehicle as  
soon as it is safe to do so. If you have any breathing  
difficulty but cannot get out of the vehicle after the  
airbag inflates, then get fresh air by opening a  
window or door.  
Warning!  
To reduce the risk of injury when the front airbags  
inflate, it is very important for the driver and front  
passenger to always be in a properly seated  
position and to wear their seat belts.  
For maximum protection in the event of a collision  
always be in normal seated position with your back  
against the backrest. Fasten your seat belt and  
ensure that it is properly positioned on your body.  
The service life of the front passenger airbag  
extends to the date indicated on the label located  
on the driver side B pillar. To provide continued  
reliability after that date, they should be inspected  
by an authorized Mercedes-Benz Light Truck  
Center at that time and replaced when necessary.  
Since the airbag inflates with considerable speed  
and force, a proper seating and hands on steering  
wheel position will help to keep you at a safe  
distance from the airbag. Occupants who are  
unbelted, out of position or too close to the airbag  
can be seriously injured by an airbag as it inflates  
with great force in the blink of an eye.

• Adjust the driver’s seat as far as possible  
rearward, still permitting proper operation of  
vehicle controls. The distance from the center  
of the driver’s breastbone to the center of the  
airbag cover on the steering wheel must be at

authorized Mercedes-Benz Light Truck Center.  
• Do not lean with your head or chest close to the  
steering wheel or dashboard.  
• Accident research shows that the safest place  
for children in an automobile is in the rear  
seat. Should you choose to place a child 12  
years old or under in the front passenger seat  
of your vehicle, you must properly use a  
BabySmartTM child restraint which will turn off  
the passenger side front airbag.  
• Keep hands on the outside of steering wheel  
rim. Placing hands and arms inside the rim  
can increase the risk and potential severity of  
hand/arm injury when the driver front airbag  
inflates.  
• Adjust the front passenger seat as far as  
possible rearward from the dashboard when  
the seat is occupied.  
Failure to follow these instructions can result in  
severe or fatal injuries to you or other occupants.

• No modifications of any kind may be made to  
any components or wiring of the “SRS”. This  
includes changing or removing any component  
or part of the “SRS”, the installation of  
Warning!  
additional trim material, badges etc. over the  
steering wheel hub, front passenger airbag  
cover, door trim panels, or door frame trims,  
and installation of additional electrical/  
electronic equipment on or near “SRS”  
components and wiring. Keep area between  
airbags and occupants free from objects (e.g.  
packages, purses, umbrellas, etc.).  
• Damaged seat belts or belts that were highly  
stressed in an accident must be replaced and  
their anchoring points must also be checked.  
Use only belts installed or supplied by an  
authorized Mercedes-Benz Light Truck Center.  
• Airbags and “ETR’s” are designed to function  
on a one-time-only basis. An airbag or  
emergency tensioning retractor (ETR) that was  
activated must be replaced.  
• An airbag system component within the  
steering wheel gets hot after the airbag has  
inflated. Do not touch.  
• Do not pass belts over sharp edges.  
• Do not make any modification that could  
change the effectiveness of the belts.  
• Improper work on the system, including  
incorrect installation and removal, can lead to  
possible injury through an unintended  
activation of the “SRS”.  
• Do not use handles above doors for placing  
such items as coat hangers etc.  
• In addition, through improper work there is a  
risk of rendering the “SRS” inoperative or  
causing unintended airbag deployment. Work  
on the “SRS” must therefore only be performed  
by an authorized Mercedes-Benz Light Truck  
Center.

Infant and child restraint systems  
Warning!  
We recommend that all infants and children be properly  
restrained at all times while the vehicle is in motion. All  
lap-shoulder belts except the driver’s seat belt have  
special seat belt retractors for secure fastening of child  
restraints.  
Never release the seat belt buckle while vehicle is  
in motion, since the special seat belt retractor will  
be deactivated.  
Important!  
To fasten a child restraint follow child restraint  
instructions for routing. Then pull shoulder belt out  
completely and let it retract. During the seat belt  
retraction a ratcheting sound can be heard to indicate  
that the special seat belt retractor is activated. The belt  
is now locked. Push down on child restraint to take up  
any slack.  
The use of infant or child restraints is required by law in  
all 50 states and all Canadian provinces.  
Infants and small children should be seated in an  
appropriate infant or child restraint system properly  
secured by a lap-shoulder belt, and that complies with  
U.S. Federal Motor Vehicle Safety Standard 213 and  
Canadian Motor Vehicle Safety Standard 213.  
A statement by the child restraint manufacturer of  
compliance with this standard can be found on the  
instruction label on the restraint and in the instruction  
manual provided with the restraint.  
To deactivate, release seat belt buckle and let seat belt  
retract completely. The seat belt can again be used in  
the usual manner.  
Note:  
When using any infant or child restraint system, be sure  
to carefully read and follow all manufacturer’s  
instructions for installation and use.  
For child seats with mounting fittings for tether  
anchorages refer to page 75 (installation of infant and  
child restraint systems).  
Please read and observe warning labels affixed to inside  
of vehicle and to infant or child restraints.

Warning!  
Children too big for child restraint systems must  
ride in back seats using regular seat belts. Position  
shoulder belt across chest and shoulder, not face or  
neck. A booster seat may be necessary to achieve  
proper belt positioning for children from 41 lbs. to  
the point where a lap/shoulder belt fits properly  
without one.  
Children 12 years old and under must never ride in  
the front seat, except in a Mercedes-Benz  
authorized BabySmartTM compatible child seat,  
which operates with the BabySmartTM System  
installed in the vehicle to deactivate the passenger  
front airbag when it is properly installed.  
Otherwise they will be struck by the airbag when it  
inflates in a crash. If this happens, serious or fatal  
injury can result.  
When the child restraint is not in use, remove it  
from the vehicle or secure it with the seat belt to  
prevent the child restraint from becoming a  
projectile in the event of an accident.  
According to accident statistics, children are safer  
when properly restrained in the rear seating  
positions than in the front seating positions.  
Infants and small children must ride in back seats  
and be seated in an infant or child restraint system,  
which is properly secured with the vehicle’s seat  
belt, fully in accordance with the child seat  
manufacturer’s instructions.  
Do not leave children unattended in the vehicle;  
even if the children are secured in a child restraint  
system. Unsupervised children in a child restraint  
system may use vehicle equipment and may cause  
serious personal injury.  
Infants and small children should never share a  
seat belt with another occupant. During an  
accident, they could be crushed between the  
occupant and seat belt.

Outside temperature indicator (12)  
Warning!  
Adaption to ambient temperature takes place in steps  
and depends on the prevailing driving conditions (stop-  
and-go or moderate, constant driving) and amount of  
temperature change.  
The outside temperature indicator is not designed  
to serve as an Ice-Warning Device and is therefore  
unsuitable for that purpose. Indicated  
temperatures just above the freezing point do not  
guarantee that the road surface is free of ice.  
Note:  
The unit for the temperature indicator display can be set  
in the individual setting menu “INSTRUMENT  
CLUSTER” – “TEMP. INDICATOR” on page 110.  
The temperature sensor is located in the front bumper  
area. Due to its location, the sensor can be affected by  
road or engine heat during idling or slow driving. This  
means that the accuracy of the displayed temperature  
can only be verified by comparison to a thermometer  
placed next to the sensor, not by comparison to external  
displays (e.g. bank signs etc.).

Mercedes-Benz Light Truck Center.  
The service indicator disappears automatically after  
30 seconds or if the knob for instrument cluster  
illumination, see page 84, in the instrument cluster is  
pressed.  
The interval between services is determined by the type  
of driving for which the vehicle is used. For example,  
driving at extreme speeds, and cold starts combined  
with short distance driving in which the engine does not  
reach operating normal temperature, reduce the interval  
between services.  
Calling up service indicator manually:  
Turn the electronic key in starter switch to position 1  
or 2.  
Call up the trip odometer and main odometer by  
pressing button è or ÿ on the multifunction

Important!  
This vehicle is equipped with an air conditioning  
system that uses R-134a (HFC: hydrofluorocarbon) as a  
refrigerant. Repairs should always be performed by a  
qualified technician, and refrigerant should be collected  
in a recovery system for recycling.

Climate control  
Notes:  
Do not obstruct the air flow by placing objects on the air  
flow-through exhaust slots on the back left and right  
trim panel in the rear cargo compartment.  
The system is always at operational readiness, except  
when manually switched off, see page 147.  
The climate control only operates with the engine  
running.  
Also keep the air intake grill in front of the windshield  
free of snow and debris.  
The air conditioning will not engage (no cooling) if the  
economy mode ACOFF is selected, see page 147.  
The air conditioner switches itself off for its own  
protection if refrigerant is lost. No cooling will then take  
place. Economy mode ACOFF cannot be switched off.  
Have the air conditioner checked by a Mercedes-Benz  
Light Truck Center should this happen.  
The temperature selector should be left at the desired  
temperature setting. The temperature selected is  
reached as quickly as possible.  
The system will not heat or cool any quicker by setting a  
higher or lower temperature.  
If the vehicle interior has been heated by direct sunlight  
and is very hot, ventilate the interior (open door or  
windows for a short period) before driving off.  
The desired interior temperature can be selected  
separately for the left and right side of the passenger  
compartment. Adjust the temperature settings in small  
increments.  
Dust filter  
Nearly all dust particles and pollen are filtered out  
before outside air enters the passenger compartment  
through the air distribution system.  
The climate control removes considerable moisture from  
the air during operation in the cooling mode. It is  
normal for water to drip on the ground through ducts in  
the underbody.

Enlarged cargo area  
Cargo tie-down rings  
The rear seat bench can be folded and lowered to  
increase the cargo area. The left, right or both seat  
backrests sections may folded down according to need.  
For folding and resetting seating to standard positions,  
see page 171.  
Warning!  
Always lock backrest in its upright position when  
rear seat bench is occupied by passengers, or cargo  
is being carried behind the seat bench.  
To help avoid personal injury from smaller objects  
flying in the occupant area during a collision or  
sudden maneuver, always use partition net when  
transporting cargo, see page 175.  
Carefully secure cargo by applying even load on all  
rings with rope of sufficient strength to hold down the  
cargo. The cargo area is provided with four tie-down  
anchors.  
Caution!  
While the partition net will help protect you from  
smaller objects, it cannot prevent the movement of  
large, heavier objects into the passenger area in an  
accident. Such items must be properly secured using  
the cargo tie-down rings in the cargo area floor.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Partition net (MB Accessory)  
Use of the partition net is a particularly important safety  
factor when the vehicle is loaded higher than the top of  
the seat backrests with smaller objects.  
The partition net can be installed behind the backrests  
of the rear seat bench, or behind the front seats if the  
rear seat bench is folded down.  
Note:  
Installation can be performed by opening the rear doors.  
For instructions on folding down rear seat bench, see  
page 171.  
Installation behind rear seat bench:  
Caution!  
To install, fold the rear seat bench cushion forward. It  
cannot be done by folding the rear seat backrest  
forward.  
While the partition net will help protect you from  
smaller objects, it cannot prevent the movement of  
large, heavier objects into the passenger area in an  
accident. Such items must be properly secured using  
the cargo tie-down rings in the cargo area floor.

P97.00-2004-26  
The total load weight including vehicle occupants and  
luggage/cargo should not exceed the vehicle capacity  
weight indicated on the certification label which can be  
found on the left door pillar.  
The handling characteristics of a fully loaded vehicle  
depend greatly on the load distribution. It is therefore  
recommended to load the vehicle according to the  
illustrations shown, with the heaviest items being  
placed towards the front of the vehicle.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Notes:  
The rear cargo area is the preferred place to carry  
objects. The enlarged cargo area (rear seats folded)  
should only be used for items which do not fit in the  
rear cargo area alone.  
Warning!  
Always fasten items being carried as securely as  
possible using cargo tie-down rings and fastening  
materials appropriate for the weight and size of the  
load.  
In an accident, during hard braking or sudden  
maneuvers, loose items will be thrown around  
inside the vehicle, and can cause injury to vehicle  
occupants unless the items are securely fastened in  
the vehicle.  
Always place items being carried against front or rear  
seat backrests, and fasten them as securely as possible.  
The heaviest portion of the cargo should always be kept  
as low as possible against front or rear seat backrest  
since it influences the handling characteristics of the  
vehicle.  
To help avoid personal injury during a collision or  
sudden maneuver, always use partition net when  
transporting cargo.  
Never drive vehicle with the tailgate open. Deadly  
carbon monoxide (CO) gases may enter vehicle  
interior resulting in unconsciousness and death.  
For additional safety when transporting cargo while the  
rear seats are unoccupied, fasten the outer seat belts  
crosswise into the opposite side buckles.

The first 1 000 miles (1 500 km)  
Maintenance  
The more cautiously you treat your vehicle during the  
break-in period, the more satisfied you will be with its  
performance later on. Therefore, drive your vehicle  
during the first 1 000 miles (1 500 km) at moderate  
vehicle and engine speeds.  
We strongly recommend that you have your vehicle  
serviced by your authorized Mercedes-Benz Light Truck  
Center, in accordance with the Service Booklet at the  
times called for by the FSS.  
Failure to have the vehicle maintained in accordance  
with the Service Booklet at the designated times/  
mileage may result in vehicle damage not covered by  
the Mercedes-Benz Limited Warranty.  
During this period, avoid heavy loads (full throttle  
driving) and excessive engine speeds.  
Avoid accelerating by kickdown. It is not recommended  
to brake the vehicle by manually shifting to a lower gear.  
We recommend that you select positions “3”, “2” or “1”  
only at moderate speeds (for hill driving).  
For information on the Flexible service system (FSS),  
see page 124.  
After 1 000 miles (1 500 km) speeds may be gradually  
increased to the permissible maximum.

Driving  
Important!  
The selector lever is automatically locked while in  
position “P”. To move the selector lever out of  
position “P”, the service brake pedal must be firmly  
depressed before the shift lock will release.  
After selecting any driving position from “N” or “P”,  
wait a moment to allow the gear to fully engage before  
accelerating, especially when the engine is cold.  
Shift selector lever to the desired position only when the  
engine is idling normally and the service brake is  
applied. Do not release the brake until ready to drive.  
The vehicle may otherwise start creeping when the  
selector lever is in drive or reverse position.  
Accelerator position  
Partial throttle = early upshifting = normal acceleration  
Full throttle = later upshifting = rapid acceleration  
Kickdown (depressing the accelerator beyond full  
throttle) = downshifting to a lower gear = maximum  
acceleration. Once the desired speed is attained, ease up  
on the accelerator – the transmission shifts up again.  
Warning!  
It is dangerous to shift the selector lever out of “P”  
or “N” if the engine speed is higher than idle speed.  
If your foot is not firmly on the brake pedal, the  
vehicle could accelerate quickly forward or in  
reverse. You could lose control of the vehicle and  
hit someone or something. Only shift into gear  
when the engine is idling normally and when your  
right foot is firmly on the brake pedal.  
Stopping  
For brief stops, e.g. at traffic lights, leave the  
transmission in gear and hold vehicle with the service  
brake.  
For longer stops with the engine idling, shift into “N”  
or “P” and hold the vehicle with the service brake.  
On slippery road surfaces, never downshift in order  
to obtain braking action. This could result in drive  
wheel slip and reduced vehicle control. Your  
vehicle’s ABS will not prevent this type of loss of  
control.  
When stopping the vehicle on an uphill gradient, do not  
hold it with the accelerator, use the brake. This avoids  
unnecessary transmission heat build up.

Maneuvering  
Warning!  
To maneuver in tight areas, e.g. when pulling into a  
parking space, control the vehicle speed by gradually  
releasing the brakes. Accelerate gently and never  
abruptly step on the accelerator.  
Getting out of your vehicle with the selector lever  
not fully engaged in position “P” is dangerous.  
Also, when parked on an incline, position “P” alone  
may not prevent your vehicle from moving,  
possibly hitting people or objects.  
To rock a vehicle out of soft ground (mud or snow),  
alternately shift from forward to reverse, while applying  
slight partial throttle.  
Always set the parking brake in addition to shifting  
to position “P”, see page 215 for parking brake.  
When parked on an incline, also turn front wheel  
against curb.  
Rocking a vehicle free in this manner may cause the  
ABS or traction system malfunction indicator lamp to  
come on. Turn off and restart the engine to clear the  
malfunction indication.  
Warning!  
When leaving the vehicle always remove the  
electronic key from the starter switch, and lock the  
vehicle. Do not leave children unattended in the  
vehicle, or with access to an unlocked vehicle.  
Children could move the gear selector lever from  
position “P”, which could result in an accident or  
serious injury.

The transmission automatically upshifts through  
5th gear. Position “D” provides optimum driving  
characteristics under all normal operating  
conditions.  
No power is transmitted from the engine to the  
drive axle. When the brakes are released, the  
vehicle can be moved freely (pushed or towed). Do  
not engage “N” while driving except to coast  
when the vehicle is in danger of skidding (e.g. on  
icy roads, see winter driving instructions on  
page 222).  
Important!  
Coasting the vehicle, or driving for any other  
reason with selector lever in “N” can result in  
transmission damage that is not covered by the  
Mercedes-Benz Limited Warranty.

Automatic transmission  
Gear selection for special circumstances  
Note:  
To avoid overrevving the engine when the selector lever  
is moved in “D –” direction, the transmission will not  
shift to a lower gear range if the engine’s revolutions  
per minute limit would be exceeded.  
The transmission gear ranges for special circumstances  
can be selected by pressing the selector lever to the  
right or the left with the selector lever in position “D”.  
The gear range currently selected is indicated in the  
instrument cluster display.  
Briefly press selector lever in the “D +” direction:  
The transmission will shift from the current gear range  
to the next higher gear range.  
Briefly press selector lever in the “D –” direction:  
The transmission will shift from the current gear range  
to the next lower gear range.  
Press and hold selector lever in the “D +” direction:  
The transmission will shift from the current gear range  
directly to gear range “D”.  
Press and hold selector lever in the “D –” direction:  
The selector lever position display will switch to the  
gear range currently selected by the automatic  
transmission.  
Important!  
Shifting into another gear range that allows for quicker  
acceleration or to slow the vehicle down is possible.  
Downshifts can also be performed.  
With transmission in gear range “D”, “4” or “3”,  
upshifting from 1st to 2nd to 3rd gear is delayed  
depending on vehicle speed and engine temperature.  
This allows the catalytic converter to heat up more  
quickly to operating temperatures.  
Warning!  
On slippery road surfaces, never downshift in order  
to obtain braking action. This could result in drive  
wheel slip and reduced vehicle control. Your  
vehicle’s ABS will not prevent this type of loss of  
control.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
During the brief warm-up period this delayed upshift  
and increased engine noise might be perceived as a  
malfunction. However, neither the engine nor  
transmission are negatively affected by this mode of  
operation.  
Gear ranges:  
Upshift through 4th gear only. Suitable for  
performance driving.  
Upshift through 3rd gear only. Suitable for  
moderately steep hills. Since the transmission  
does not shift higher than 3rd gear, this gear  
selection will allow use of the engine’s braking  
power downhill.  
The delayed upshift is effective with vehicle speeds  
below 31 mph (50 km/h) at partial throttle and engine  
temperatures below 95°F (35°C).  
To prevent the engine from laboring at low RPM when  
driving uphill gradients or with your vehicle heavily  
loaded, the automatic transmission will downshift when  
necessary to maintain engine RPM within the best  
torque range.  
Upshift through 2nd gear only. For driving in  
mountainous regions or under extreme operating  
conditions. This gear selection will allow use of  
the engine’s braking power when descending  
steep grades.  
For notes on driving the vehicle in transfer case  
position “LOW”, see page 248.  
Use this position, which makes maximum use of  
the engine’s braking effect, while descending  
very steep or lengthy downgrades.  
Note:  
To avoid overrevving the engine on the rpm limit, the  
transmission will upshift automatically to the next  
higher gear range as long as the vehicle is accelerating.

Emergency operation (Limp home mode)  
To engage 2nd gear or reverse:  
If vehicle acceleration worsens or the transmission no  
longer shifts, the transmission is most likely operating  
in Limp home mode which engages when there is a  
malfunction of the transmission. This condition may be  
accompanied by the “CHECK ENGINE” malfunction  
indicator lamp in the instrument cluster coming on.  
1. Stop the vehicle.  
2. Move selector lever to position “P”.  
3. Turn key in starter switch to position 0.  
4. Wait at least 10 seconds.  
In this mode only the 2nd gear or reverse gear can be  
activated.  
5. Restart the engine.  
6. Move selector lever to position “D” (for 2nd gear), or  
move selector lever to position “R” (for reverse gear).  
Have the transmission checked at your authorized  
Mercedes-Benz Light Truck Center as soon as possible.

Drinking and driving  
Warning!  
Drive sensibly – save fuel  
Drinking or taking drugs and driving can be a very  
dangerous combination. Even a small amount of  
alcohol or drugs can affect your reflexes,  
perceptions and judgement.  
Fuel consumption, to a great extent, depends on driving  
habits and operating conditions.  
To save fuel you should:  
The possibility of a serious or even fatal accident is  
sharply increased when you drink or take drugs  
and drive.  
keep tires at the recommended inflation pressures,  
remove unnecessary loads,  
allow engine to warm up under low load use,  
avoid frequent acceleration and deceleration,  
Please do not drink or take drugs and drive or allow  
anyone to drive after drinking or taking drugs.  
have all maintenance work performed at regular  
intervals by an authorized Mercedes-Benz Light  
Truck Center.  
Pedals  
Warning!  
Fuel consumption is also increased by driving in cold  
weather, in stop-and-go traffic, on short trips and in hilly  
country.  
Keep driver’s foot area clear at all times. Objects  
stored in this area may impair pedal movement.

Power assistance  
Warning!  
Excessive use of road salt and other snow melting  
chemicals spread on roads during the winter months  
may cause a build up of moisture or residue to form on  
the braking components. This build up or residue could  
cause light corrosion of the braking components if the  
vehicle is parked with the brakes cold. Apply steady and  
even braking pressure when stopping the vehicle to  
warm up and dry the brake components.  
When the engine is not running, the brake and  
steering systems are without power assistance.  
Under these circumstances, a much greater effort is  
necessary to stop or steer the vehicle.  
Important!  
Brakes  
Please pay attention to the function of the brake assist  
system (BAS), see page 237.  
Warning!  
After driving in heavy rain for some time without  
applying the brakes or through water deep enough  
to wet brake components or salty road conditions,  
the first braking action may be somewhat reduced  
and increased pedal pressure may be necessary to  
obtain expected braking effect. Be sure to maintain  
a safe distance from vehicles in front.  
The condition of the parking brake system is checked  
each time the vehicle is in the shop for the required  
maintenance service.  
If the parking brake is released and the brake warning  
lamp in the instrument cluster stays on and there is no  
audible warning (EBB), the brake fluid level in the  
reservoir is too low.  
Resting your foot on the brake pedal will cause  
excessive and premature wear of the brake pads.  
Brake pad wear or a leak in the system may be the  
reason for low brake fluid in the reservoir.  
It can also result in the brakes overheating thereby  
significantly reducing their effectiveness. It may  
not be possible to stop the vehicle in sufficient time  
to avoid an accident.  
Have the brake system inspected at an authorized  
Mercedes-Benz Light Truck Center immediately.

Driving instructions  
All checks and service work on the brake system should  
be carried out by an authorized Mercedes-Benz Light  
Truck Center.  
Driving off  
Apply the service brakes to test them briefly after  
driving off. Perform this procedure only when the road  
is clear of other traffic.  
Install only brake pads and brake fluid recommended by  
Mercedes-Benz.  
Warm up the engine smoothly. Do not place full load on  
the engine until the operating temperature has been  
reached.  
Warning!  
If other than recommended brake pads are  
installed, or other than recommended brake fluid  
is used, the braking properties of the vehicle can be  
degraded to an extent that safe braking is  
substantially impaired. This could result in an  
accident.  
When starting off on a slippery surface, do not allow one  
drive wheel to spin for an extended period with the ESP  
switched off. Doing so may cause serious damage to the  
drive train which is not covered by the Mercedes-Benz  
Limited Warranty.  
To ensure sufficient traction during off-road driving,  
activate differential locks as needed, see page 253.  
Caution!  
When driving down long and steep grades, relieve the  
load on the brakes by shifting into a lower gear to use  
the engine’s braking power. This helps prevent  
overheating of the brakes and reduces brake pad wear.  
After hard braking, it is advisable to drive on for some  
time, rather than immediately parking, so the air stream  
will cool down the brakes faster.

Parking  
Tires  
Warning!  
Warning!  
To reduce the risk of personal injury as a result of  
vehicle movement, before turning off the engine  
and leaving the vehicle, always:  
If you feel a sudden significant vibration or ride  
disturbance, or you suspect that possible damage to  
your vehicle has occurred, you should turn on the  
hazard warning flashers, carefully slow down, and  
drive with caution to an area which is a safe  
distance from the roadway.  
1. Keep right foot on the service brake pedal.  
2. Pull the parking brake lever up as many  
notches as possible.  
Inspect the tires and under the vehicle for possible  
damage. If the vehicle or tires appear unsafe, have  
it towed to the nearest Mercedes-Benz Light Truck  
Center or tire dealer for repairs.  
3. Move the selector lever to position “P”.  
4. Slowly release the service brake pedal.  
5. Turn front wheels towards the road curb.  
Tread wear indicators (TWI) are required by law. These  
indicators are located in six places on the tread  
circumference and become visible at a tread depth of  
approximately 1/16 in (1.5 mm), at which point the tire is  
considered worn and should be replaced.  
6. Turn the electronic key to starter switch  
position 0 and remove.  
7. Take the key and lock vehicle when leaving.  
The tread wear indicator appears as a solid band across  
the tread.  
Important!  
It is advisable to set the parking brake whenever  
parking or leaving the vehicle. In addition, move  
selector lever to position “P”.  
Note:  
For instructions on towing the vehicle, see page 324.  
When parking on hills, always set the parking brake.

Driving instructions  
Specified tire pressures must be maintained. This  
applies particularly if the tires are subjected to high  
loads (e.g. high speeds, heavy loads, high ambient  
temperatures).  
Warning!  
Do not drive with a flat tire. A flat tire affects the  
ability to steer or brake the vehicle. You may lose  
control of the vehicle. Continued driving with a flat  
tire or driving at high speed with a flat tire will  
cause excessive heat build-up and possibly a fire.  
Aquaplaning  
Depending on the depth of the water layer on the road,  
aquaplaning may occur, even at low speeds and with  
new tires. Reduce vehicle speed, avoid track grooves in  
the road and apply brakes cautiously in the rain.  
Warning!  
Do not allow your tires to wear down too far. As  
tread depth approaches 1/16 in (1.5 mm), the  
adhesion properties on a wet road are sharply  
reduced.  
Depending upon the weather and/or road surface  
(conditions), the tire traction varies widely.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Tire traction  
Tire speed rating  
The safe speed on a wet, snow covered or icy road is  
always lower than on a dry road.  
Your vehicle is factory equipped with “V”-rated tires,  
which have a speed rating of 150 mph (240 km/h).  
You should pay particular attention to the condition of  
the road whenever the outside temperatures are close to  
the freezing point.  
An electronic speed limiter prevents your vehicle from  
exceeding the tire speed rating.  
Despite the tire rating, local speed limits should be  
obeyed. Use prudent driving speeds appropriate to  
prevailing conditions.  
Warning!  
If ice has formed on the road, tire traction will be  
substantially reduced. Under such weather  
conditions, drive, steer and brake with extreme  
caution.  
Warning!  
Even when permitted by law, never operate a  
vehicle at speeds greater than the maximum speed  
rating of the tires.  
We recommend M+S rated radial-ply tires with a  
minimum tread depth of approximately 1/8 in (4 mm)  
for the winter season for all four wheels to insure  
normal balanced handling characteristics. On packed  
snow, they can reduce your stopping distance as  
compared with summer tires. Stopping distance,  
however, is still considerably greater than when the  
road is not snow or ice covered.  
Exceeding the maximum speed for which tires are  
rated can lead to sudden tire failure causing loss of  
vehicle control and resulting in personal injury  
and possible death.

Snow chains  
Winter driving instructions  
Use only snow chains that are tested and recommended  
by Mercedes-Benz. Your authorized Mercedes-Benz  
Light Truck Center will be glad to advise you on this  
subject.  
The most important rule for slippery or icy roads is to  
drive sensibly and to avoid abrupt acceleration, braking  
and steering maneuvers. Do not use the cruise control  
system under such conditions.  
Snow chains should be used on all four wheels. Follow  
the manufacturer’s mounting instructions.  
When the vehicle is in danger of skidding, move  
selector lever to position “N”. Try to keep the vehicle  
under control by corrective steering action.  
Snow chains should only be driven on snow covered  
roads at speeds not to exceed 30 mph (50 km/h).  
Remove chains as soon as possible when driving on  
roads without snow.  
Important!  
Avoid spinning of one drive wheel. This may cause  
serious damage to the drive train which is not covered  
by the Mercedes-Benz Limited Warranty.  
To ensure sufficient traction during off-road driving,  
activate differential locks as needed, see page 253.  
ABS, ESP and BAS are switched off automatically when  
the transfer case differential lock is activated.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
Road salts and chemicals can adversely affect braking  
efficiency. Increased pedal force may become necessary  
to produce the normal brake effect. We therefore  
recommend depressing the brake pedal periodically  
when traveling at length on salt-strewn roads. This can  
bring road salt impaired braking efficiency back to  
normal. A prerequisite is, however, that this be done  
without endangering other drivers on the road.  
Winter driving  
Have your vehicle winterized at your authorized  
Mercedes-Benz Light Truck Center before the onset of  
winter.  
Check the engine oil. Change the engine oil if the  
engine contains an oil which is not approved for  
winter operation. For viscosity (SAE/CCMC class)  
and filling quantity, see page 361.  
If the vehicle is parked after being driven on salt treated  
roads, the braking efficiency should be tested as soon as  
possible after driving is resumed while observing the  
safety rules in the previous paragraph.  
Check engine coolant anticorrosion/antifreeze  
concentration.  
Additive for the windshield washer and headlamp  
cleaning system: Add MB Concentrate “S” to a  
premixed windshield washer solvent/antifreeze  
which is formulated for below freezing temperatures  
see page 307.  
Warning!  
If the vehicle becomes stuck in snow, make sure  
that snow is kept clear of the exhaust pipe and  
from around the vehicle with engine running.  
Otherwise, deadly carbon monoxide (CO) gases may  
enter vehicle interior resulting in unconsciousness  
and death.  
Test battery: Battery capacity drops with decreasing  
ambient temperature. A well charged battery helps  
to ensure that the engine can be started, even at low  
ambient temperatures.  
To assure sufficient fresh air ventilation, open a  
window slightly on the side of the vehicle not  
facing the wind.  
Tires: We recommend M+S rated radial-ply tires on  
all four wheels for the winter season. Observe  
permissible maximum speed for M+S rated  
radial-ply tires and the legal speed limit.

In winter operation, the maximum effectiveness of the  
antilock brake system (ABS), the four wheel electronic  
traction system (4-ETS), the electronic stability program  
(ESP), and electronic brake booster (EBB) can only be  
achieved with M+S rated radial-ply tires and/or snow  
chains recommended by Mercedes-Benz. Snow chains  
maximize performance.  
Deep water  
Caution!  
Do not drive through flooded areas or water of unknown  
depth. Before driving through water, determine its  
depth. It should not be deeper than approximately  
20 inches (50 cm).  
For driving instructions using snow chains see  
page 222.  
If you must drive through deep water, drive slowly to  
prevent water from entering the engine compartment or  
passenger compartment, being ingested by the air  
intake, possibly causing damage to electrical  
components or wiring, to engine or transmission that is  
not covered by the Mercedes-Benz Limited Warranty.

under off-road conditions. For switching the transfer  
case in position LOW, see page 247.  
Watch out for obstacles, such as rocks, holes,  
tree-stumps, ruts.

Be especially careful when driving in unknown  
territory. It is good practice to get out of the vehicle and  
scout the path you intend to take.  
Checklist before off-road driving  
• Engine oil level: Check the engine oil level, see  
page 127 and page 304. The display “ENGINE OIL  
LEVEL – O.K.” must appear in the multifunction  
display.  
Continuous and speedy driving in sandy soil overcomes  
the vehicle rolling resistance, and helps to prevent the  
vehicle from sinking into the ground. Switch on the  
differential locks, see page 253.  
Only then is a trouble free oil supply obtained even  
on steep gradients with the vehicle.  
Do not initiate jumps with the vehicle. It interrupts the  
forward momentum of the vehicle.  
• Tires: Check the tread depth and maintain specified  
tire pressure (see tire pressure label inside the fuel  
filler flap). Check tires for possible damage and  
remove foreign objects. The valve caps must be  
mounted.  
Always drive on slopes with the engine running and the  
vehicle in gear.  
Sand, dirt, mud and other material having friction  
property, can cause exceptional wear and tear as well as  
failure of the brakes.  
• Rims: Dented or bent rims can cause tire pressure  
loss and damage the tire beads. For this reason,  
check and, if necessary, change rims before driving  
off-road.  
In this case the brakes may be less effective or even fail  
when you most need them. Always clean and check the  
brakes following each off-road trip.  
• Vehicle toolkit: Check if the vehicle jack is  
functional. In all cases take the vehicle tool kit, a  
strong tow rope, a shovel and a small plank (to put  
under the vehicle jack on sandy soil) with you.

Driving in steep terrain  
Maximum vehicle climbing ability is a 80% grade.  
Driving on embankments, slopes and other steep  
inclines should only be done straight up or downhill, i.e.  
in the line of gravity.  
Do not drive along the side of a slope (danger of vehicle  
rollover). If in doing so, the vehicle begins to show a  
tendency to roll, immediately steer into a line of gravity  
(straight up or downhill).  
To help avoid the vehicle rolling over, never turn it  
around on steep inclines. If the vehicle cannot complete  
the attempted climb, back it down in reverse gear.  
1
2
Utilize the engine’s braking power when descending a  
slope, observe the engine speed (do not overrev the  
engine). Apply the service brake as needed.  
P00.00-3186-26  
Slope angle:  
Check the brakes after a lengthy downgrade drive.  
1 27°  
Notes:  
2 36°  
Avoid excessive engine speeds – drive with moderate  
engine speeds (max. 3000 RPM).  
Switch the transfer case in position LOW before starting  
to drive up or down steep inclines, see page 248.  
Select gear range “2” or “1” on the automatic  
transmission, see page 207.  
If necessary activate differential locks, see page 253.  
ABS, BAS and ESP are switched off automatically when  
the differential locks are activated.

Traction in steep terrain:  
Drive downhill observing the same rules as driving  
uphill.  
Be easy on the accelerator and watch for continuous  
wheel traction when driving in steep terrain.  
Driving on embankments, slopes and other steep  
inclines should only be done straight up or downhill, i.e.  
in the line of gravity.  
When the differential locks are not engaged, 4-ETS  
helps greatly when starting out on a steep incline. The  
front wheels have then the tendency to slip due to the  
weight reduction over the front axle. The ETS  
recognizes the situation and limits the torque for the  
front wheels by braking them. Simultaneously the  
torque for the rear wheels is increased.  
Do not drive along the side of a slope (danger of vehicle  
rollover). If in doing so, the vehicle begins to show a  
tendency to roll, immediately steer into a line of gravity  
(straight up or downhill).  
Utilize the engine’s braking power when descending a  
slope, observe the engine speed (do not overrev the  
engine). Apply the service brake as needed.  
See page 241 for four wheel electronic traction system  
(4-ETS).  
The special LOW range ABS setting allows for precise  
and brief (cyclical) blocking of the front wheels,  
permitting them to dig into loose ground. Remember  
that the front wheels when stopped, slide across a  
surface, thus loose their ability to steer the vehicle.  
Driving across a hilltop:  
To prevent the vehicle from speeding up too much after  
climbing a hill, decelerate just ahead of a hilltop (do not  
select gear range “N”). Use the momentum of the  
vehicle to drive across the hilltop. Driving in this  
manner prevents the vehicle from jumping across the  
hilltop and thus loosing its forward momentum.  
Check the brakes after a lengthy downgrade drive.  
Important!  
Only apply the service brake if the vehicle travels  
straight downhill, i.e. in the line of gravity.  
Driving downhill:  
Select gear range “1” on the automatic transmission,  
see page 207.

Driving through water  
Switch the transfer case in position LOW before driving  
through water.  
If necessary activate differential locks, see page 253.  
ABS, BAS and ESP are switched off automatically when  
the differential locks are activated.  
Switch off the exterior lamps as well as the climate  
control.  
Enter the water only at a shallow spot. Never take a  
running start. Drive slowly, avoiding a bow wave.  
Do not stop vehicle immersed in water, and do not shut  
off the engine.  
To dry the brakes, apply pressure to the brake pedal  
several times after leaving the water.  
1 20 in (50 cm)  
Before driving through water, determine its depth. It  
should not be deeper than approximately  
20 inches (50 cm).

Important!  
Damage on the vehicle definitely increases the chance  
for a subsequent accident.  
Notes:  
Check the vehicle clearance before crossing obstacles  
that possibly could damage the undercarriage.  
If possible use the assistance of a second person.  
Special attention is needed when crossing obstacles on  
a steep incline. The vehicle could slide sideways as a  
result of its possible slanted position.  
Crossing obstacles:  
Select gear range “1” on the automatic transmission,  
see page 207.  
If necessary activate differential locks, see page 253.  
ABS, BAS and ESP are switched off automatically when  
the differential locks are activated.  
Cross obstacles (e.g. tree stumps or big rocks) very  
slowly by aiming one of the front wheels at the center of  
the obstacle, and repeat same with the rear wheel.

see page 207.  
Damage on the vehicle definitely increases the chance  
for a subsequent accident.  
If necessary activate differential locks, see page 253.  
ABS, BAS and ESP are switched off automatically when  
the differential locks are activated.  
A number of off-road tracks or other byways have deep  
ruts which can cause the undercarriage to come in  
contact with the ground.  
Drive next to the ruts rather than through them if at all  
possible.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Returning from off-road driving  
Check for brush or branches caught in the  
undercarriage. They could increase the possibility of  
a fire, as well as cut fuel and/or brake lines,  
puncture rubber bellows of the axles or drive shafts.  
Off-road driving increases strain on the vehicle.  
We recommend that you inspect the vehicle for possible  
damage after each off-road trip. Recognizing any  
damage and a subsequent timely repair reduces the  
chance of a possible breakdown or accident later on.  
Warning!  
Never drive on pavement with activated differential  
locks. Engaged front axle differential locks limits  
ability to move around curves.  
Proceed as follows:  
Disengage the differential locks, see page 253.  
If you feel a sudden significant vibration or ride  
disturbance, or you suspect that possible damage to  
your vehicle has occurred, you should turn on the  
hazard warning flashers, carefully slow down, and  
drive with caution to an area which is a safe  
distance from the roadway.  
Engage the transfer case in position HIGH, see  
page 247.  
Remove excessive dirt from tires, wheels, wheel  
housings, and underbody. For instance, after driving  
in mud, clean the radiator, chassis, engine, brakes,  
and wheels from extreme dirt, using a strong jet of  
water.  
Inspect the tires and under the vehicle for possible  
damage. If the vehicle or tires appear unsafe, have  
it towed to the nearest Mercedes-Benz Light Truck  
Center or tire dealer for repairs.  
Inspect frame, oil pan, brake hoses, etc., as well as  
vehicle underbody for possible damage.  
Check tires for possible damage, clean all exterior  
lamps, and conduct a brake test.

Cruise control  
1 Accelerate and set:  
Lift lever briefly to set speed.  
Hold lever up to accelerate.  
1
2 Decelerate and set:  
Depress lever briefly to set speed.  
Hold lever down to decelerate.  
3
Normally the vehicle is accelerated to the desired  
speed with the accelerator.  
Speed is set by briefly pushing the lever to  
position 1 or 2. The accelerator can then be  
released.  
4
The speed can be increased (e.g. for passing) by  
using the accelerator. After the accelerator is  
released, the previously set speed will be resumed  
automatically.  
2
The cruise control allows you to drive in a more relaxed  
manner, for example over long distances, as it  
automatically maintains the set speed by actively  
regulating the throttle setting.  
If a set speed is to be increased or decreased  
slightly, e.g. to adapt to the traffic flow, hold lever in  
position 1 or 2 until the desired speed is reached, or  
briefly tip the lever in the appropriate direction for  
increases or decreases in 0.6 mph (1 km/h)  
increments. When the lever is released, the newly  
set speed remains.  
Any given speed above approximately 25 mph  
(40 km/h) can be maintained with the cruise control by  
operating the lever.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
3 Canceling  
Important!  
To cancel the cruise control, briefly push lever to  
position 3.  
Moving gear selector lever to position “N” switches the  
cruise control off.  
When you step on the brake pedal or the vehicle  
speed drops below approximately 25 mph  
(40 km/h), for example when driving upgrade, the  
cruise control will be canceled.  
Warning!  
Only use the cruise control if the traffic and  
weather conditions make it advisable to travel at a  
steady speed.  
If the cruise control cancels by itself and remains  
inoperative until the engine is restarted, have the  
system checked at your authorized Mercedes-Benz  
Light Truck Center as soon as possible.  
• The use of cruise control can be dangerous on  
winding roads or in heavy traffic because  
conditions do not allow safe driving at a steady  
speed.  
4 Resume  
• The use of cruise control can be dangerous on  
slippery roads. Rapid changes in tire adhesion  
can result in wheel spin and loss of control.  
If the lever is briefly pushed to position 4 when  
driving at a speed exceeding approximately 25 mph  
(40 km/h), the vehicle resumes the speed which  
was set prior to the cancellation of the cruise  
control. The last memorized speed is canceled when  
the electronic key in the starter switch is turned to  
position 1 or 0.  
The “Resume” function should only be operated if  
the driver is fully aware of the previously set speed  
and wishes to resume this particular preset speed.

Notes:  
Transmission in position LOW  
If the engine does not brake the vehicle sufficiently  
while driving on a downgrade, the speed you set on the  
cruise control may be exceeded. In this case the  
automatic transmission shifts down (max. to 3rd gear)  
to maintain the set cruise control speed by using the  
engine’s braking power.  
The cruise control should not be activated during off-  
road driving in transfer case position LOW. Doing so  
could reduce driving comfort.  
As soon as the grade eases, the automatic transmission  
shifts up again dependent on the selector lever position.  
Nevertheless, in some cases you may have to step on the  
brake pedal to slow down. In this case the cruise control  
is switched off.  
Use the lever to resume the previously set speed.  
For malfunction and warning messages, see page 272.

Brake assist system (BAS)  
Warning!  
The BAS is designed to maximize the vehicle’s braking  
capability during emergency braking maneuvers by  
having maximum power boost applied to the brakes  
more quickly in emergency braking conditions than  
might otherwise be afforded solely by the driver’s  
braking style. This can help reduce braking distances  
over what ordinary driving and braking style might do.  
The BAS complements the antilock brake system (ABS).  
BAS cannot prevent the natural laws of physics  
from acting on the vehicle, nor can it increase  
braking efficiency beyond that afforded by the  
condition of the vehicle brakes and tires or the  
traction afforded. The BAS cannot prevent  
accidents, including those resulting from excessive  
speed in turns, following another vehicle too  
closely, or aquaplaning. Only a safe, attentive, and  
skillful driver can prevent accidents. The  
capabilities of a BAS equipped vehicle must never  
be exploited in a reckless or dangerous manner  
which could jeopardize the user’s safety or the  
safety of others.  
Applying the brakes very quickly results in maximum  
BAS assistance.  
To receive the benefit of the system you must apply  
continuous full braking power during the stopping  
sequence. Do not reduce brake pedal pressure.  
Once the brake pedal is released, the BAS is deactivated.  
At the instant one of the wheels is about to lock up, a  
slight pulsation can be felt in the brake pedal,  
indicating that the ABS is in the regulating mode. Keep  
firm and steady pressure on the brake pedal while  
experiencing the pulsation.

With the BAS malfunctioning the ABS, ESP and 4-ETS  
are also switched off.  
If the É malfunction indicator lamp and the ESP  
warning lamp stay illuminated and warning messages  
appears in the multifunction display, have the BAS and  
ESP checked at your authorized Mercedes-Benz Light  
Truck Center as soon as possible.  
If the ESP warning lamp and the É malfunction  
indicator lamp come on permanently while the engine is  
running, a malfunction has been detected in either  
system. As a result, it is possible that now only partial  
engine output will be available. If the BAS malfunctions,  
the brake system functions in the usual manner, but  
without BAS.  
For warning messages and malfunction indicator lamps,  
see page 264 and page 272.  
If the charging voltage falls below 10 volts, the ESP  
warning lamp, the É malfunction indicator lamp  
come on and warning messages appears in the  
multifunction display, the BAS and the ESP are switched  
off. When the voltage is above this value again, the  
malfunction indicator and warning lamp should go out  
and the BAS is operational.

Antilock brake system (ABS)  
Warning!  
In the case of an emergency brake maneuver keep  
continuous full pressure on the brake pedal. In this  
manner only can the ABS be most effective.  
On slippery road surfaces, the ABS will respond even  
with light brake pedal pressure because of the  
increased likelihood of locking wheels. The pulsating  
brake pedal can be an indication of hazardous road  
conditions and functions as a reminder to take extra  
care while driving.  
Do not pump the brake pedal, rather use firm,  
steady brake pedal pressure. Pumping the brake  
pedal defeats the purpose for ABS and significantly  
reduces braking effectiveness.  
Important!  
The ABS improves steering control of the vehicle during  
hard braking maneuvers.  
ABS control  
The ABS malfunction indicator lamp - in the  
instrument cluster comes on with the electronic key in  
starter switch position 2 and should go out with the  
engine running.  
The ABS prevents the wheels from locking up above a  
vehicle speed of approximately 5 mph (8 km/h)  
independent of road surface conditions.  
At the instant one of the wheels is about to lock up, a  
slight pulsation can be felt in the brake pedal,  
indicating that the ABS is in the regulating mode. Keep  
firm and steady pressure on the brake pedal while  
experiencing the pulsation.  
When the ABS malfunction indicator lamp - in the  
instrument cluster comes on while the engine is  
running, it indicates that the ABS has detected a  
malfunction and has switched off. In this case, the brake  
system functions in the usual manner, but without  
antilock assistance.  
Continuous steady brake pedal pressure results in  
applying the advantages of the ABS, namely braking  
power and ability to steer the vehicle.  
With the ABS malfunctioning, the BAS, ESP and 4-ETS  
are also switched off. The malfunction indicator lamps  
come on with the engine running.

The ABS malfunction indicator lamp - also comes  
on, when the differential lock is engaged. The ABS is  
switched off, but there is no malfunction in the system.  
Notes:  
To alert following vehicles to slippery road conditions  
you discover, operate your hazard warning flashers as  
appropriate.  
If the charging voltage falls below 10 volts, the  
malfunction indicator lamp comes on and the ABS is  
switched off. When the voltage is above this value again,  
the malfunction indicator lamp should go out and the  
ABS is operational.  
Operating the vehicle on a single axle dynamometer  
should only be done for briefly testing the brakes. To do  
so, move selector lever to position “N”. The engine must  
be shut off (electronic key in starter switch position 0  
or 1).  
If the ABS malfunction indicator lamp stays illuminated,  
have the system checked at your authorized  
Mercedes-Benz Light Truck Center as soon as possible.  
For ABS malfunction and warning messages, see  
page 275.  
Warning!  
LOW RANGE – ABS  
ABS cannot prevent the natural laws of physics  
from acting on the vehicle, nor can it increase  
braking or steering efficiency beyond that afforded  
by the condition of the vehicle brakes and tires or  
the traction afforded. The ABS cannot prevent  
accidents, including those resulting from excessive  
speed in turns, following another vehicle too  
closely, or aquaplaning. Only a safe, attentive, and  
skillful driver can prevent accidents. The  
capabilities of an ABS equipped vehicle must never  
be exploited in a reckless or dangerous manner  
which could jeopardize the user’s safety or the  
safety of others.  
During off-road driving a special low range system for  
the antilock brake system (ABS) is operational with  
transfer case in position LOW, see page 247.  
An improved braking action (dig in effect) is obtained  
for vehicle speeds up to 37 mph (60 km/h) through a  
change in the ABS control function.

Four-wheel electronic traction system (4-ETS)  
4-ETS Control  
With the electronic key in starter switch position 2, the  
warning lamp v located in the speedometer dial  
comes on and should go out when the engine is  
running.  
If the É malfunction indicator lamp and the ESP  
warning lamp stay illuminated and warning messages  
appears in the multifunction display with the engine  
running, a malfunction has been detected.  
The 4-ETS improves vehicle’s ability to utilize available  
traction, especially under slippery road conditions. The  
brakes are applied to the spinning wheel and power is  
transferred to the wheel(s) with traction. The 4-ETS  
function is available between vehicle speed  
Have the 4-ETS checked at your authorized  
Mercedes-Benz Light Truck Center as soon as possible.  
With the ABS malfunctioning, the 4-ETS is also  
switched off.  
0 mph (km/h) and 37 mph (60 km/h).  
Caution!  
The 4-ETS warning lamp v starts to flash at any  
vehicle speed, as soon as the tires loose traction and the  
wheels begin to spin.  
If the vehicle is towed with the front axle raised (see  
towing the vehicle on page 324), or when testing the  
parking brake on a brake test dynamometer, the engine  
must be shut off (electronic key in starter switch  
position 0 or 1). Otherwise, the electronic traction  
system will immediately be engaged and will apply the  
rear wheel brakes.  
Important!  
If the 4-ETS warning lamp v flashes:  
during take-off, apply as little throttle as possible,  
while driving, ease up on the accelerator.  
Adapt your speed and driving to the prevailing road  
conditions.

Note:  
Electronic Brake Booster (EBB)  
In winter operation, the maximum effectiveness of the  
electronic traction system is only achieved with  
Mercedes-Benz recommended M+S rated radial-ply tires  
and/or snow chains.  
The EBB enhances braking effectiveness by allowing the  
rear brakes to supply a greater proportion of the braking  
effort without a loss of vehicle stability.  
If a warning tone sounds for five seconds and the  
symbols É, v and - are displayed in the  
instrument cluster, the system has detected a  
malfunction and is switched off. Have the system  
checked immediately at an authorized Mercedes-Benz  
Light Truck Center. Failure to do so could result in an  
accident, since the enhanced braking effect is not  
available when the system is switched off.  
Note:  
When the EBB is switched off, every time the engine is  
started, a warning tone will sound for five seconds and  
the symbols É and - will light up. In addition,  
whenever the brakes are applied at speeds exceeding  
25 mph (40 km/h), the warning tone sounds for five  
seconds.

Electronic stability program (ESP)  
Warning!  
Important!  
If the ESP warning lamp v flashes:  
During take-off apply as little throttle as possible.  
While driving ease up on the accelerator.  
ESP cannot prevent the natural laws of physics  
from acting on the vehicle, nor can it increase the  
traction afforded. The ESP cannot prevent  
accidents, including those resulting from excessive  
speed in turns, or aquaplaning. Only a safe,  
attentive, and skillful driver can prevent accidents.  
The capabilities of an ESP equipped vehicle must  
never be exploited in a reckless or dangerous  
manner which could jeopardize the user’s safety or  
the safety of others.  
Adapt your speed and driving to the prevailing road  
conditions.  
Do not switch off the ESP.  
Caution!  
If the vehicle is towed with the front axle raised (see  
towing the vehicle on page 324), the engine must be  
shut off (electronic key in starter switch position 0 or 1).  
Otherwise, the ESP will immediately be engaged and  
will apply the rear wheel brakes.  
The ESP enhances directional control and reduces  
driving wheel spin of the vehicle under various driving  
conditions.  
Over-/understeering of the vehicle is counteracted by  
applying brakes to the appropriate wheel to create a  
countervailing vehicle movement. Engine torque is also  
limited. The ESP warning lamp, located in the  
speedometer dial, starts to flash when ESP is in  
operation.  
Notes:  
The yellow ESP warning lamp v in the speedometer  
dial comes on with the electronic key in starter switch  
position 2. They should go out with the engine running.

If the ESP warning lamp v comes on continuously  
and warning messages appears in the multifunction  
display with the engine running, a malfunction has  
been detected in either system. Only partial engine  
output will be available.  
When testing the parking brake on a brake test  
dynamometer, the engine must be shut off. Otherwise,  
the ESP will immediately be engaged and will apply the  
rear wheel brakes.  
In winter operation, the maximum effectiveness of the  
ESP is only achieved with Mercedes-Benz recommended  
M+S rated radial-ply tires and/or snow chains.  
If the BAS malfunctions, the brake system functions in  
the usual manner, but without BAS, ESP and 4-ETS.  
If the ESP warning lamp v and the  
É malfunction indicator lamp come on and warning  
messages appears in the multifunction display, have the  
BAS or ESP checked at your authorized Mercedes-Benz  
Light Truck Center as soon as possible.  
Synchronizing ESP  
If the power supply was interrupted (battery  
disconnected or empty), the ESP warning lamp v  
and warning messages appears in the multifunction  
display with the engine running.  
With the ABS malfunctioning, the BAS, ESP and 4-ETS  
are also switched off.  
Turn steering wheel completely to the left and then to  
the right. The ESP warning lamp v and the warning  
messages in the multifunction display should go out.  
For warning messages and malfunction indicator lamps,  
see page 264 and page 272.  
Driving the vehicle with varied size tires will cause the  
wheels to rotate at different speeds, therefore the ESP  
may activate (yellow ESP warning lamp v in  
speedometer dial comes on). For this reason, all wheels,

If the ESP is switched off, it will be automatically  
activated when exceeding a vehicle speed of 37 mph  
(60 km/h) or exceeding a severity threshold of side  
acceleration.  
Note:  
Avoid spinning of one drive wheel. This may cause  
serious damage to the drive train which is not covered  
by the Mercedes-Benz Limited Warranty.  
If one drive wheel loses traction and begins to spin, the  
brake is applied until the wheel regains sufficient  
traction. The traction control is available between  
vehicle speed 0 mph (km/h) and 37 mph (60 km/h).  
The ESP warning lamp, located in the speedometer dial,  
starts to flash at any vehicle speed as soon as the tires  
lose traction and the wheels begin to spin.  
To return to the enhanced vehicle stability offered by  
ESP: press lower half of the switch (the ESP warning  
lamp in the speedometer dial goes out).  
Important!  
If the ESP warning lamp flashes:  
during take-off, apply as little throttle as possible,  
while driving, ease up on the accelerator.

A few words about differentials and differential  
locks  
light off-road driving. The position “LOW” of the  
transfer case (see pages 247and 226) also enhances  
off-road driving capabilities.  
When a vehicle negotiates a turn, wheels on the outside  
of the curve must travel farther and rotate faster than  
the inside wheels. The differential, the operation of a set  
of gears that allow the powered wheels in a vehicle to  
turn a different speeds, provides for this essential  
function.  
More extreme off-road conditions may call for another  
cure which is to engage a differential lock, preventing  
the differential from operating altogether. This vehicle  
offers as standard equipment three differential locks:  
front, transfer case (center), and rear. Each can be  
engaged simply by pushing a dashboard-mounted  
button (see pages 253 and 254 for engaging differential  
locks). When the transfer case (center) differential is  
locked, half of the engine's power is automatically  
distributed to the front wheels and half to the rear  
wheels. When the rear differential is locked, power  
going to the rear wheels is equally distributed, so that  
both rear wheels turn at the same speed and torque.  
When the front differential is locked, all four wheels  
now turn with equal power and torque. Please be aware  
that engaging the differential locks will significantly  
reduce steering ability of the vehicle.  
The drawback is that the differential also sends most of  
the engine's power to the wheel with the least load or  
strain on it. For example, if one of a vehicle's powered  
wheels sits on a patch of snow and spins because there  
is no traction, all of the engine's power will go to that  
wheel because the power will take the path of least  
resistance. Meanwhile, the opposite wheel, sitting on  
dry pavement where it could get enough grip to start the  
vehicle moving, sits idle because it gets no power.  
The Electronic Traction System (ETS) addresses this  
problem and provides for good control and steering  
ability by automatically slowing the slipping wheel and  
thus increasing the power to the other non-slipping  
drive wheels to get the vehicle moving. The ESP and ETS  
in this vehicle feature such intelligent limited-slip  
differential technology, ideally suited for on-road and

It is important to understand that during on-road/paved  
driving, differentials are absolutely required to provide  
essential control and steering ability of the vehicle. The  
differential locks, therefore, must not be engaged when  
driving on paved roads and should only be used when  
and to the extent necessary to negotiate off-road  
conditions not addressable by the systems (automatic  
ETS, ESP; manual switch position “LOW” of transfer-  
case) this vehicle comes equipped with.

Important!  
To engage differential locks:  
Do not engage the front axle differential lock when  
driving around tight corners as steering ability is  
restricted.  
Warning!  
Never drive on pavement with activated differential  
locks.  
When the transfer case differential lock is activated, the  
ESP, ABS and BAS are automatically switched off.  
The ABS malfunction indicator lamp and the ESP  
warning lamp in the instrument cluster come on.  
Further appear alternately the messages “ESP NOT  
ACTIVE – LOCK ACTIVE”, “BAS NOT AVAILABLE –  
LOCK ACTIVE” and “ABS NOT ACTIVE – LOCK  
ACTIVE” in the multifunction display.  
Important!  
To avoid damage to the transfer case and differential  
locks:  
• Engage differential locks only at low speed  
(walking speed, not more than 5 mph).  
• Do not engage differential locks if the driving  
wheels are spinning.  
The differential locks should be engaged when driving  
off-road, for example:  
for driving trough water or  
when driving on deep snow, icy or fouled surfaces.  
For notes on off-road driving, see page 226.

The function indicator lamp (5) comes on when the  
differential lock engagement procedure has been  
completed. The ABS malfunction indicator lamp and the  
ESP warning lamp in the instrument cluster come on.  
Further appear alternately the messages “ESP NOT  
ACTIVE – LOCK ACTIVE”, “BAS NOT AVAILABLE –  
LOCK ACTIVE” and “ABS NOT ACTIVE – LOCK  
ACTIVE” in the multifunction display.  
Only apply the accelerator lightly when driving off.  
Briefly press the switch for the differential lock  
required. The corresponding engagement indicator  
lamp (4) comes on.

Methods to disengage differential locks  
Only when all function indicator lamps (5) have gone  
out, the ABS malfunction indicator lamp and the ESP  
warning lamp in the instrument cluster go out and the  
messages “ESP NOT ACTIVE – LOCK ACTIVE”, “BAS  
NOT AVAILABLE – LOCK ACTIVE” and “ABS NOT  
ACTIVE – LOCK ACTIVE” in the multifunction display  
disappear.  
There are two different methods to disengage  
differential locks:  
Disengage differential locks in reverse order. When  
the rear axle differential lock is disengaged, the  
front axle differential lock is automatically  
disengaged with it.  
Now the message “ESP – NOT AVAILABLE” appears in  
the multifunction display and the ESP warning lamp  
comes on. That means the ESP, BAS and ABS functions  
are not active yet.  
Briefly press the previously activated switches for  
the differential lock. The correspondending  
engagement indicator lamp (4) goes out.  
To activate the systems again drive for 3 seconds with a  
constant drive behavior.  
If the transfer case differential lock is disengaged,  
all other differential locks are automatically  
disengaged.  
Note:  
Briefly press the switch (1) for the transfer case  
differential lock. The engagement indicator  
lamps (4) go out.  
If the function lamps do not go out when the differential  
locks are disengaged, make minor changes to the  
vehicles direction.  
The function indicator lamp (5) goes out when the  
disengagement procedure has been completed.

Important!  
Warning!  
When running on a (single-axle) dynamometer – no  
matter how briefly – the non driven axle must be  
raised or its drive shaft disconnected. The transfer  
differential lock must be engaged. Otherwise the  
transfer case can be damaged, which is not covered  
by the Mercedes-Benz Limited Warranty.  
Never drive on pavement with activated differential  
locks.  
Steering control will be strongly affected with the  
front differential lock activated.  
ABS, BAS and ESP are switched off automatically  
when the transfer case differential lock is  
activated.

Warning!  
Inhalation of exhaust gas is hazardous to your  
health. All exhaust gas contains carbon monoxide,  
and inhaling it can cause unconsciousness and  
lead to death.  
General information:  
If a bulb in the instrument cluster fails to light up  
during the bulb self-check when turning the key in  
starter switch to position 2, have it checked and  
replaced if necessary.  
Do not run the engine in confined areas (such as a  
garage) which are not properly ventilated. If you  
think that exhaust gas fumes are entering the  
vehicle while driving, have the cause determined  
and corrected immediately. If you must drive under  
these conditions, drive only with at least one  
window fully open.  
Emission control  
Certain systems of the engine serve to keep the toxic  
components of the exhaust gases within permissible  
limits required by law.  
These systems, of course, will function properly only  
when maintained strictly according to factory  
specifications. Any adjustments on the engine should,  
therefore, be carried out only by authorized  
Mercedes-Benz Light Truck Center qualified  
technicians. Engine adjustments should not be altered  
in any way. Moreover, the specified service jobs must be  
carried out regularly according to Mercedes-Benz  
servicing requirements. For details refer to the Service  
Booklet.

On-board diagnostic system  
The Sequential Multiport Fuel Injection (SFI) control  
module monitors emission control components that  
either provide input signals to or receive output signals  
from the control module. Malfunctions resulting from  
interruptions or failure of any of these components are  
indicated by the “CHECK ENGINE” malfunction  
indicator lamp in the instrument cluster and are  
simultaneously stored in the SFI control module.  
Check engine malfunction indicator lamp  
Engine malfunction indicator lamp. If the  
“CHECK ENGINE” malfunction indicator  
lamp comes on when the engine is running,  
it indicates a malfunction of the fuel management  
system, emission control system, systems which impact  
emissions, or the fuel cap is not closed tight (check the  
fuel cap). If the “CHECK ENGINE” lamp is illuminated  
continuously and the vehicle is driving normally, you  
may still drive the vehicle, however, in all cases, we  
recommend that you have the system checked at your  
authorized Mercedes-Benz Light Truck Center as soon  
as possible.  
If the “CHECK ENGINE” malfunction indicator lamp  
comes on, have the system checked at your authorized  
Mercedes-Benz Light Truck Center as soon as possible.  
With some exceptions, the control module switches off  
the “CHECK ENGINE” malfunction indicator lamp if the  
condition, causing the lamp to come on, no longer exists  
during three consecutive cycles.  
If the “CHECK ENGINE” lamp comes on continuously  
and/or the vehicle is not driving normally (e.g.  
malfunction of the fuel management system or running  
out of fuel), serious damage can occur to the emission  
system. Please contact your authorized Mercedes-Benz  
Light Truck Center immediately.  
An on-board diagnostic connector is located in  
passenger compartment on the driver’s side near hood  
lock release on the upper left of footwell, allowing the  
accurate identification of system malfunctions through  
the readout of diagnostic trouble codes.

Warning!  
Driving with the brake warning lamp illuminated  
can result in an accident. Have your brake system  
checked immediately if the brake warning lamp  
stays on. Do not add brake fluid before checking the  
brake system. Overfilling the brake fluid reservoir  
can result in spilling brake fluid on hot engine  
parts and the brake fluid catching fire. You can be  
seriously burned.  
Except Canada  
Canada only  
When the brake warning lamp and message appear  
while the engine is running, this means:  
there is insufficient brake fluid in the reservoir  
Note:  
(engine running and parking brake released), or  
If you find that the minimum mark on the brake fluid  
reservoir is reached, have the brake system checked for  
brake pad thickness and leaks.  
the parking brake is set (engine running).  
If a warning tone sounds for 5 seconds and the warning  
lamps É and - are displayed in the instrument  
cluster, the electronic brake booster (EBB) has a

Supplemental restraint system (SRS) indicator lamp  
Warning!  
When turning the electronic key in starter  
switch to position 1 the indicator lamp “SRS”  
in the instrument cluster comes on. If no  
fault is detected, the lamp will go out after  
approximately 4 seconds.  
In the event a malfunction of the “SRS” is indicated  
as outlined above, the “SRS” may not be  
operational. For your safety, we strongly  
recommend that you visit an authorized  
Mercedes-Benz Light Truck Center immediately to  
have the system checked; otherwise the “SRS” may  
not be activated when needed in an accident, which  
could result in serious or fatal injury, or it might  
deploy unexpectedly and unnecessarily which  
could also result in injury.  
When turning the electronic key in starter switch to  
position 2 the indicator lamp “SRS” in the instrument  
cluster comes on. If no fault is detected, the lamp will go  
out when the engine is running.  
The operational readiness of the airbag system is  
verified by the indicator lamp “SRS” in the instrument  
cluster when turning the electronic key in starter switch  
to position 1 or 2.  
See page 66 for notes on airbags, see page 71 for belt  
tensioners and page 73 for infant and child seat  
restraint.  
After the lamp goes out, the system continues to  
monitor the components and circuitry of the airbag  
system and will indicate a malfunction by coming on  
again.

Malfunction and indicator lamps  
Fuel reserve warning  
When the warning lamp (1) comes on after starting the  
engine, or if it comes on while driving, it indicates that  
the fuel level is down to the reserve quantity of  
approximately 5.3 US gal (20 liters). In addition to the  
warning lamp, the message “RESERVE FUEL” –“VISIT  
FUEL STATION” appears in the multifunction display.  
See page 258 for notes on refueling the vehicle.  
After refueling the vehicle, the message  
“1 MALFUNCTION” appears in the multifunction  
display when turning the electronic key in starter  
switch to position 2. This malfunction message has to be  
cleared, see page 106 for notes on the malfunction/  
warning message memory.

ABS malfunction indicator lamp  
The ABS malfunction indicator lamp in the  
instrument cluster comes on with the  
electronic key in starter switch position 2  
and should go out with the engine running.  
If a warning tone sounds for 5 seconds and the warning  
lamps - and É are displayed in the instrument  
cluster, the EBB has a malfunction and is switched off.  
See page 242 for notes on the electronic brake booster  
(EBB).  
ABS  
If the charging voltage falls below 10 volts, the  
malfunction indicator lamp comes on and the ABS is  
switched off. When the voltage is above this value again,  
the malfunction indicator lamp should go out and the  
ABS is operational.  
When the ABS malfunction indicator lamp symbol and  
warning in the instrument cluster remains illuminated  
while the engine is running, it indicates that the ABS  
has detected a malfunction and has switched off. In this  
case, the brake system functions in the usual manner,  
but without antilock assistance.  
Have the system checked at your authorized  
Mercedes-Benz Light Truck Center as soon as possible.  
A malfunctioning ABS control unit can possibly affect  
the operation of other systems (e.g. Navigation,  
Automatic transmission). Be guided accordingly with  
respect to the use of those systems and have the system  
checked at your authorized Mercedes-Benz Light Truck  
Center as soon as possible.  
See page 239 for notes on antilock brake system (ABS).  
Note:  
If the transfer case differential lock is engaged the ABS  
warning lamp comes on and the ABS, ESP, BAS, EBB  
and 4-ETS are switched off. There is no malfunction in  
the system.  
With the ABS malfunctioning the BAS, ESP, EBB and  
4-ETS are also switched off. The malfunction indicator  
lamps and malfunction messages in the multifunction  
display come on with the engine running.

Electronic stability program (ESP) — warning lamp  
Seat belt nonusage warning lamp  
The yellow ESP warning lamp in the  
speedometer dial comes on with the  
electronic key in starter switch position 2.  
It should go out with engine running.  
With the electronic key in starter switch  
position 2, the seat belt nonusage warning  
lamp comes on, and a warning sounds for a  
short time if the drivers seat belt is not fastened.  
If the ESP malfunction indicator lamp remains  
illuminated with the engine running, a malfunction has  
been detected in the system. Pressing the accelerator  
pedal will require greater effort. Only partial engine  
output will be available.  
After starting the engine, the seat belt nonusage  
warning lamp blinks for a brief period to remind the  
driver and passengers to fasten seat belts.  
With the ESP malfunctioning, the abs, BAS, EBB and  
4-ETS are also switched off.  
See electronic stability program (ESP) on page 243 if the  
warning lamp lights up or flashes when the vehicle is  
moving.  
Note:  
If the transfer case differential lock is engaged the ESP  
warning lamp comes on and the ESP, ABS, BAS and  
4-ETS are switched off. There is no malfunction in the  
system.

Warning!  
The BabySmartTM airbag deactivation system will  
ONLY work with a special child seat designed to  
operate with it. It will not work with child seats  
which are not BabySmartTM compatible.  
AIRBAG OFF indicator lamp  
The ü indicator lamp will light up for approximately  
6 seconds when you turn the electronic key in starter  
switch to position 1 or 2.  
Never place anything between seat cushion and  
child seat (e.g. pillow), since it reduces the  
effectiveness of the deactivation system.  
It does not light up if there is a fault in the system.  
Follow the manufacturer’s instructions for  
installation of special child seats.  
The ü indicator lamp stays lit as long as a  
Baby SmartTM child seat is properly installed on the  
front passenger seat. It indicates that the front  
passenger airbag is switched off.  
The passenger front airbag will not deploy only if  
the ü indicator lamp remains illuminated.  
Please be sure to check the indicator every time  
you use the special system child seat. Should the  
light go out while the restraint is installed, please  
check installation. If the light remains out, do not  
use the BabySmartTM restraint to transport children  
on the front passenger seat until the system has  
been repaired.

Checking engine oil level  
Wipe oil dipstick clean prior to checking the engine oil  
level. Fully insert dipstick in tube, and remove after  
three seconds to obtain accurate reading.  
Oil level must be between the  
lower (min) and upper (max) mark of  
the dipstick.  
Fill quantity between upper and lower dipstick marking,  
the level is approximately 2.1 US qt (2.0 l).  
Do not overfill the engine. Excessive oil must be drained  
or siphoned. It could cause damage to engine and  
catalytic converter not covered by the Mercedes-Benz  
Limited Warranty.  
1 Oil filler cap  
See malfunction and warning messages on page 282 if  
an engine oil level display appears on the multifunction  
indicator when the engine is running.  
2 Oil dipstick  
To check the engine oil level, park vehicle on level  
ground, with engine at normal operational temperature.  
Note:  
Check engine oil level approximately 5 minutes after  
stopping the engine, allowing for the oil to return to the  
oil pan.  
See page 127 for engine oil level indicator.  
The oil dipstick tube allows for draining of oil by using a  
suction device.

Automatic transmission fluid level  
Engine oil consumption  
The transmission has a permanent fill of automatic  
transmission fluid.  
Engine oil consumption checks should only be made  
after the break-in period. During the break-in period,  
higher oil consumption may be noticed and is normal.  
Frequent driving at high engine speeds results in  
increased consumption.  
Regular automatic transmission fluid level checks and  
changes are not required. For this reason the dipstick is  
omitted.  
If you notice fluid leaks or gear shifting malfunctions,  
have your authorized Mercedes-Benz Light Truck Center  
check the transmission fluid level.

Coolant level  
Adding coolant  
If coolant has to be added, a 50/50 mixture of water and  
MB anticorrosion/antifreeze should be added.  
Warning!  
1
In order to avoid possible serious burns or injury:  
• Use extreme caution when opening the hood if  
there are any signs of steam or coolant leaking  
from the cooling system, or if the coolant  
temperature gauge indicates that the coolant is  
overheated.  
• Do not remove pressure cap on coolant  
reservoir if engine temperature is above 194°F  
(90°C). Allow engine to cool down before  
removing cap. The coolant reservoir contains  
hot fluid and is under pressure.  
To check the coolant level, the vehicle must be parked  
on level ground and the engine stopped.  
Check coolant level only when coolant is cold.  
• Using a rag, slowly open cap approximately  
1/2 turn to relieve excess pressure. If opened  
immediately, scalding hot fluid and steam will  
be blown out under pressure.  
The coolant level should reach the COLD LEVEL mark in  
the reservoir.  
Anticorrosion/antifreeze mixture, see page 366.  
• Do not spill antifreeze on hot engine parts.  
Antifreeze contains ethylene glycol which may  
burn if it comes into contact with hot engine  
parts.  
After adding coolant, close cap until you hear it click a  
few times.

Tire replacement  
Replace rims or tires with the same designation,  
manufacturer and type as shown on the original part.  
See your authorized Mercedes-Benz Light Truck Center  
for further information.  
Front and rear tires should be replaced in sets. Rims  
and tires must be of the correct size and type. For  
dimensions, see technical data on page 359.  
We recommend that you break in new tires for  
approximately 60 miles (100 km) at moderate speed.  
Warning!  
It is imperative that the wheel mounting bolts be  
fastened to a tightening torque of 97 ft.lb. (130 Nm)  
whenever wheels are mounted.  
Do not mix different tire construction types (i.e.  
radial, bias, bias-belted) on your vehicle because  
handling may be adversely affected and may result  
in loss of control.  
For rim and tire specifications, refer to technical data on  
page 359.  
See your authorized Mercedes-Benz Light Truck Center  
for information on tested and recommended rims and  
tires for summer and winter operation. They can also  
offer advice concerning tire service and purchase.  
Warning!  
Worn, old tires can cause accidents. If the tire tread  
is badly worn, or if the tires have sustained  
damage, replace them.  
When replacing rims, use only genuine  
Mercedes-Benz wheel bolts specified for the  
particular rim type. Failure to do so can result in  
the bolts loosening and possibly an accident.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Rotating wheels  
Notes:  
The wheels can be rotated according to the degree of  
tire wear while retaining the same direction of travel.  
Thoroughly clean the inner side of the wheels any time  
you rotate the wheels or wash the vehicle underside.  
Rotating, however, should be carried out as  
The use of retread tires is not recommended. Retread  
tires may adversely affect the handling characteristics  
and safety of the vehicle.  
recommended by the tire manufacturer, before the  
characteristic tire wear pattern (shoulder wear on front  
wheels and tread center wear on rear wheels) becomes  
visible, as otherwise the driving properties deteriorate.  
Dented or bent rims can cause tire pressure loss and  
damage to the tire beads. For this reason, check rims for  
damage at regular intervals. The rim flanges must be  
checked for wear before a tire is mounted. Remove  
burrs, if any.  
Important!  
Unidirectional tires must always be mounted with arrow  
on tire sidewall pointing in direction of vehicle forward  
movement.  
Check and ensure proper tire inflation pressure after  
rotating the wheels. For tire inflation pressure see  
page 318.

Tires, Wheels  
Tire inflation pressure  
Tire pressures listed for light loads are minimum values  
offering high driving comfort. Increased inflation  
pressures for heavy loads produce favorable handling  
characteristics with lighter loads and are perfectly  
permissible. The ride of the vehicle, however, will  
become somewhat harder.  
A table (see fuel filler flap) lists the tire inflation  
pressures specified for Mercedes-Benz recommended  
tires as well as for the varying operating conditions.  
Important!  
Tire temperature and pressure increase with the vehicle  
speed. Tire pressure should therefore only be checked  
and corrected on cold tires. Correct tire pressure in  
warm tires only if pressure has dropped below the  
pressure listed in the table and the respective operating  
conditions are taken into consideration.  
Tire pressure changes by approximately 1.5 psi (0.1 bar)  
per 18°F (10°C) of air temperature change. Keep this in  
mind when checking tire pressure inside a garage –  
especially in the winter.  
Example:  
If garage temperature = approximately +68°F (+20°C)  
and ambient temperature = approximately +32°F (0°C)  
then the adjusted air pressure = specified air pressure  
+3 psi (+0.2 bar).  
An underinflated tire due to a slow leak (e.g. due to a  
nail in the tire) may cause damage such as tread  
separation, bulging etc.. Regular tire pressure checks  
(including the spare tire) at intervals of no more than  
14 days are therefore essential.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
If a tire constantly loses air, it should be inspected for  
damage.  
Battery  
Warning!  
The spare tire should be checked periodically for  
condition and inflation. Spare tire will age and become  
worn over time even if never used, and thus should be  
inspected and replaced when necessary.  
Failure to follow these instructions can result in  
severe injury or death.  
Never lean over batteries while connecting, you  
might get injured.  
Warning!  
Battery fluid contains sulfuric acid. Do not allow  
this fluid to come in contact with eyes, skin or  
clothing. In case it does, immediately flush affected  
area with water and seek medical help if necessary.  
Do not overinflate tires. Overinflating tires can  
result in sudden deflation (blowout) because they  
are more likely to become punctured or damaged  
by road debris, potholes etc.. Follow recommended  
inflation pressures.  
A battery will also produce hydrogen gas, which is  
flammable and explosive. Keep flames or sparks  
away from battery, avoid improper connection of  
jumper cables, smoking etc..  
Do not overload the tires by exceeding the specified  
vehicle capacity weight (as indicated by the label  
on the driver’s door latch post). Overloading the  
tires can overheat them, possibly causing a  
blowout.  
Important!  
Battery replacement information:  
The maintenance-free battery is located in front of the  
rear seat bench and below the cup holder.  
Jump starting terminals are located in the left side of the  
engine compartment, see page 321.

Battery  
The service life of the battery is dependent on its  
condition of charge. The battery should always be kept  
sufficiently charged, in order to last an optimum length  
of time.  
While the engine is running the battery terminal clamps  
must not be loosened or detached, otherwise the  
generator and other electronic components would be  
damaged.  
Therefore, we strongly recommend that you have the  
battery charge checked frequently, and corrected if  
necessary, especially if you use the vehicle less than  
approximately 200 miles (300 km) per month,  
mostly for short distance trips, or if it is not used for  
long periods of time.  
Note:  
The gear selector lever will remain locked in  
position “P” and the electronic key can not be turned in  
the starter switch, if the vehicle battery is disconnected  
or discharged.  
After reconnecting the battery also set the clock (see  
COMAND operator’s manual), synchronize the  
electronic stability program (ESP) (see page 244) and  
the front seat head restraints (see page 47).  
Only charge a battery with a battery charger after the  
battery has been disconnected from the vehicle’s  
electrical circuit.  
Always disconnect the battery negative lead first and  
connect last.  
Battery recycling  
When removing and connecting the battery, always  
make sure that all electrical consumers are off and the  
key is in starter switch position 0. The battery must  
always be securely installed when the vehicle is in  
operation. During removal and installation always  
protect the disconnected battery positive (+) terminal  
with the cover attached to the battery.  
Batteries contain material that can harm the  
environment with improper disposal.  
Large 12 Volt storage batteries contain lead.  
Recycling of batteries is the preferred method of  
disposal.  
Many states require sellers of batteries to accept old  
batteries for recycling.

Jump starting  
Warning!  
Important!  
A discharged battery can freeze at approximately +14°F  
(–10°C). In that case, it must be thawed out before  
jumper cables are used. Attempting to jump start a  
frozen battery can result in it exploding, causing  
personal injury.  
Failure to follow these directions will cause  
damage to the electronic components, and can lead  
to a battery explosion and severe injury or death.  
Never lean over batteries while connecting or jump  
starting, you might get injured.  
Jumper cable specifications:  
Minimum cable cross-section of 25 mm2 or  
Battery fluid contains sulfuric acid. Do not allow  
this fluid to come in contact with eyes, skin or  
clothing. In case it does, immediately flush affected  
area with water, and seek medical help if  
necessary.  
approximately 2 AWG  
Maximum length of 11.5 ft. (3.5 m).  
If the battery is discharged, the engine should be started  
with jumper cables and the (12 V) battery of another  
vehicle.  
A battery will also produce hydrogen gas, which is  
flammable and very explosive. Keep flames or  
sparks away from battery, avoid improper  
connection of jumper cables, smoking etc..  
Only use 12 V battery to jump start your vehicle. Jump  
starting with more powerful battery could damage the  
vehicle’s electrical systems, which will not be covered  
by the Mercedes-Benz Limited Warranty.  
Read all instructions before proceeding.  
The battery is located in front of the rear seat bench and  
below the cup holder.

Towing  
Towing the vehicle  
Important!  
When towing the vehicle, please, note the following:  
Prior to towing the vehicle with all wheels on the  
ground, make certain that the electronic key is in  
starter switch position 2.  
Towing of the vehicle should only be done using the  
properly installed towing eye bolt. Never attach tow  
cable, tow rope or tow rod to vehicle chassis, frame  
or suspension parts.  
If the electronic key is left in the starter switch  
position 0 for an extended period of time, it can no  
longer be turned in the switch. In this case, the  
steering is locked. To unlock, remove electronic key  
from starter switch and reinsert.  
The vehicle may be towed with all wheels on the  
ground and the selector lever in position “N” for  
distances up to 30 miles (50 km) and at a speed not  
to exceed 30 mph (50 km/h). The key must be in  
starter switch position 2.  
With the engine not running, there is no power  
assistance for the braking and steering systems. In  
this case, it is important to keep in mind that a  
considerably higher degree of effort is necessary to  
brake and steer the vehicle.  
With the automatic central locking activated and the  
engine running, the vehicle doors lock if the left front  
wheel is turning at vehicle speeds of approximately  
9 mph (15 km/h) or more.  
Notes:  
To prevent the vehicle door locks from locking,  
deactivate the automatic central locking. See the  
individual setting menu “VEHICLE” – “AUTOMATIC  
DOOR LOCK” on page 118.  
The selector lever will remain locked in position “P” and  
the electronic key cannot be turned in the starter switch  
if the battery is disconnected or discharged. See battery  
on page 319 or jump starting on page 321.  
We recommend that the vehicle be transported using  
flat bed equipment. This method is preferable to other  
types of towing.  
In order to move the vehicle, shift automatic  
transmission to position “N”.  
To prevent damage during transport, do not tie down  
vehicle by its chassis or suspension parts.  
Transmission selector lever, manually unlocking, see  
page 327.

Electrical malfunction  
Notes:  
When removing drive shaft, place M10 nuts on bolts as  
distance sleeves and tighten using M8 nuts.  
To be certain to avoid additional damage to the vehicle  
powertrain, however you should do the following:  
Always install new self-locking nuts when reinstalling  
the drive shaft.  
Shift automatic transmission to position “N”.  
Caution!  
Important!  
If the vehicle is towed with the front axle raised, the  
engine must be shut off (electronic key in starter switch  
position 1). Otherwise, the 4-ETS may become engaged  
which may cause loss of towing control. Switch off the  
tow-away alarm (see page 43) as well as the ESP (see  
page 245).  
Vehiclemaybe towedfor distancesup to30 miles  
(50 km) and at a speed not to exceed 30 mph  
(50 km/h).  
For towing vehicle for distances exceeding 30 miles  
(50 km) or if the vehicle has a damaged transfer  
case, remove drive shafts to the drive axles.  
When towing vehicle with one axle raised, the  
electronic key in starter switch must be in  
position 1.  
Note:  
To signal turns while being towed with hazard warning  
flasher in use, turn electronic key in starter switch to  
position 1 and activate combination switch for left or  
right turn signal in usual manner. Now deactivate the  
hazard warning flasher, only the selected turn signal  
will operate. Upon canceling the turn signal, the hazard  
warning flasher must be activated again.  
With damage to front axle, raise front axle. Remove  
drive shaft between rear axle and transfer case.  
With damage to rear axle, raise rear axle and tow  
vehicle with wheel lift or dolly placed under front  
wheels.

Stranded vehicle  
Freeing a stranded vehicle, on which the wheels are dug  
into sand or mud, should be done with the greatest of  
care, especially if the vehicle is heavily loaded.  
Avoid pulling the vehicle jerkily or diagonally, since it  
could result in damage to the chassis alignment.  
Never try to free a vehicle that is still coupled to a  
trailer.  
If possible, a vehicle equipped with trailer hitch receiver  
should be pulled backward in its own previously made  
tracks.  
In the case of power failure the transmission selector  
lever can be manually unlocked, e.g. to tow the vehicle.  
To do so, insert a pin (1), e.g. ball point pen, into the  
covered opening below the position “D” of the shift  
pattern. While pushing the pin down, move selector  
lever from position “P”.  
After removal of the pin from the opening, the cover will  
not close fully. Only after moving the selector lever to  
positions “D+” and “D–” does the cover return to its  
closed position.

Cleaning and care of the vehicle  
Cleaning and care of the vehicle  
More frequent washings are necessary to deal with  
unfavorable conditions; for example, near the ocean, in  
industrial areas (smoke, exhaust emissions), or during  
winter operation.  
Warning!  
Many cleaning products can be hazardous. Some  
are poisonous, others are flammable. Always follow  
the instructions on the particular container.  
Always open your vehicle’s doors or windows when  
cleaning the inside.  
You should check your vehicle from time to time for  
stone chipping or other damage. Any damage should be  
repaired as soon as possible to prevent the start of  
corrosion.  
Never use fluids or solvents that are not designed  
for cleaning your vehicle.  
In doing so, do not neglect the underside of the vehicle.  
A prerequisite for a thorough check is a washing of the  
underbody followed by a thorough inspection. Damaged  
areas need to be reundercoated.  
In operation, your vehicle is subjected to varying  
external influences which, if gone unchecked, can  
attack the paintwork as well as the underbody and  
cause lasting damage.  
Your vehicle has been treated at the factory with a wax-  
base rustproofing in the body cavities which will last for  
the lifetime of the vehicle. Post-production treatment is  
neither necessary nor recommended by Mercedes-Benz  
because of the possibility of incompatibility between  
materials used in the production process and others  
applied later.  
Such damage is caused not only by extreme and varying  
climatic conditions, but also by air polution, road salt,  
tar, gravel and stone chipping. Grease and oil, fuel,  
coolant, brake fluid, bird droppings, insects, tree resins  
etc. should be removed immediately to avoid paint  
damage. Frequent washing reduces and/or eliminates  
the aggressiveness and potency of the above adverse  
influences.  
We have selected car-care products and compiled  
recommendations which are specially matched to our  
vehicles and which always reflect the latest technology.  
You can obtain Mercedes-Benz approved car-care  
products at your authorized Mercedes-Benz Light Truck  
Center.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Scratches, corrosive deposits, corrosion or damage due  
to negligent or incorrect care cannot always be removed  
or repaired with the car-care products recommended  
here. In such cases it is best to seek aid at your  
authorized Mercedes-Benz Light Truck Center.  
Tar stains  
Quickly remove tar stains before they dry and become  
more difficult to remove. A tar remover is  
recommended.  
The following topics deal with the cleaning and care of  
your vehicle and give important “how-to” information as  
well as references to Mercedes-Benz approved car-care  
products.  
Paintwork, painted body components  
Mercedes-Benz approved Paint Care should be applied  
when water drops on the paint surface do not “bead up”,  
normally in 3 to 5 months, depending on climate and  
washing detergent used.  
Additional information can be found in the booklet titled  
Vehicle Care Guide”.  
Mercedes-Benz approved Paint Cleaner should be  
applied if paint surface shows signs of dirt embedding  
(i.e. loss of gloss).  
Power washer  
When using a power washer for cleaning the vehicle  
always observe manufacturers’ operating instructions.  
Do not apply any of these products or wax if your  
vehicle is parked in the sun or if the hood is still hot.  
Use the appropriate MB-Touch-Up Stick for quick and  
provisional repairs of minor paint damage (i.e. chips  
from stones, vehicle doors etc.).  
Caution!  
Never use a round nozzle to power wash tires. The  
intense jet of water can result in damage to the tire.  
Always replace a damaged tire.  
Always keep the jet of water moving across the surface.  
Do not aim directly at electrical parts, electrical  
connectors, seals, or other rubber parts.

Cleaning and care of the vehicle  
Engine cleaning  
Due to the width of the vehicle, prior to running the  
vehicle through an automatic car wash, fold back the  
outside mirrors to prevent them from getting damaged.  
Prior to cleaning the engine compartment make sure to  
protect electrical components and connectors from the  
intrusion of water and cleaning agents.  
In the winter, thoroughly remove all traces of road salt  
as soon as possible.  
Corrosion protection, such as MB Anticorrosion Wax  
should be applied to the engine compartment after  
every engine cleaning. Before applying, all control  
linkage bushings and joints should be lubricated. The  
poly-V-belt and all pulleys should be protected from any  
wax.  
When washing the underbody, do not forget to clean the  
inner sides of the wheels.  
Ornamental moldings  
For regular cleaning and care of very dirty chrome-  
plated parts, use a chrome cleaner.  
Vehiclewashing  
Do not use hot water or wash your vehicle in direct  
sunlight. Use only a mild car wash detergent, such as  
Mercedes-Benz approved Car Shampoo.  
Headlamps, taillamps, turn signal lenses  
Use a mild car wash detergent, such as Mercedes-Benz  
approved Car Shampoo, with plenty of water.  
Thoroughly spray the vehicle with a diffused jet of  
water. Direct only a very weak spray towards the  
ventilation intake. Use plenty of water and rinse the  
sponge and chamois frequently.  
To prevent scratches, never apply strong force and use  
only a soft, non-scratchy cloth when cleaning the lenses.  
Do not attempt to wipe dirty lenses with a dry cloth or  
sponge.  
Rinse with clear water and thoroughly wipe dry with a  
chamois. Do not allow cleaning agents to dry on the  
finish.

Window cleaning  
Light alloy wheels  
Use a window cleaning solution on all glass surfaces. An  
automotive glass cleaner is recommended.  
Mercedes-Benz approved Wheel Care should be used for  
regular cleaning of the light alloy wheels.  
If possible, clean wheels once a week with  
Mercedes-Benz approved Wheel Care, using a soft  
bristle brush and a strong spray of water.  
Note:  
For safety reasons, switch off wipers and remove key  
from starter switch before cleaning the windshield,  
otherwise the wiper motor can suddenly turn on and  
cause injury.  
Follow instructions on container.  
Note:  
Use only acid-free cleaning materials. The acid could  
lead to corrosion or may damage the clear coat.  
Wiper blades  
Clean the wiper blade inserts with a clean cloth and  
detergent solution.  
Instrument cluster  
Use a gentle dishwashing detergent or mild detergent  
for delicate fabrics as a washing solution. Wipe with a  
cloth moistened in lukewarm solution. Do not use  
scouring agents.  
Note:  
For safety reasons, switch off wipers and remove key  
from starter switch before cleaning the wiper blades,  
otherwise the wiper motor can suddenly turn on and  
cause injury.  
Steering wheel and gear selector lever  
Wipe with a damp cloth and dry thoroughly or clean

Cleaning and care of the vehicle  
Cup holder  
Upholstery  
Use a gentle dishwashing detergent or mild detergent  
for delicate fabrics as a washing solution. Wipe with a  
cloth moistened in lukewarm solution. Do not use  
scouring agents.  
Using aftermarket seat covers or wearing clothing that  
have the tendency to give off coloring (e.g. when wet  
etc.) may cause the upholstery to become permanently  
discolored. By lining the seats with a proper  
intermediate cover, contact-discoloration will be  
prevented.  
Seat belts  
Leather Upholstery  
The webbing must not be treated with chemical  
cleaning agents. Use only clear, lukewarm water and  
soap. Do not dry the webbing at temperatures above  
176°F (80°C) or in direct sunlight.  
Wipe leather upholstery with a damp cloth and dry  
thoroughly or clean with Mercedes-Benz approved  
Leather Care. Exercise particular care when cleaning  
perforated leather as its underside should not become  
wet.  
Warning!  
Cloth Upholstery  
Clean with soft bristle brush, or use a dry-shampoo  
cleaner in case of excessive dirt.  
Do not bleach or dye seat belts as this may severely  
weaken them. In a crash they may not be able to  
provide adequate protection.  
Hard plastic trim items  
Headliner  
Pour Mercedes-Benz approved Interior Care onto soft  
lint-free cloth and apply with light pressure.  
Clean with soft bristle brush, or use a dry-shampoo  
cleaner in case of excessive dirt.  
Plastic and rubber parts  
Do not use oil or wax on these parts.

Engine oils  
Air conditioner refrigerant  
R-134a (HFC) refrigerant and special PAG lubricating oil  
is used in the air conditioner system.  
Engine oils are specifically tested for their suitability in  
our engines. Therefore, use only engine oils  
recommended by Mercedes-Benz. Information on  
recommended brands is available in the Factory  
Approved Service Products pamphlet, or at your  
authorized Mercedes-Benz Light Truck Center.  
Never use R-12 (CFC) or mineral-based lubricating oil,  
otherwise damage to the system will occur.  
Brake fluid  
Please follow Service Booklet recommendations for  
scheduled oil changes. Failure to do so could result in  
engine damage not covered by the Mercedes-Benz  
Limited Warranty.  
During vehicle operation, the boiling point of the brake  
fluid is continuously reduced through the absorption of  
moisture from the atmosphere. Under extremely hard  
operating conditions, this moisture content can lead to  
the formation of bubbles in the system thus reducing  
the system’s efficiency.  
Engine oil additives  
Do not blend oil additives with engine oil. They may be  
harmful to the engine operation.  
The brake fluid must therefore be replaced every two  
years, preferably in the spring.  
Damage or malfunctions resulting from blending oil  
additives are not covered by the Mercedes-Benz Limited

Premium unleaded gasoline  
Fuel requirements  
Use only Premium unleaded meeting ASTM  
standard D 439:  
Caution!  
To maintain the engine’s durability and performance,  
premium unleaded gasoline must be used. If premium  
unleaded is not available and low octane fuel is used,  
follow these precautions:  
The octane number (posted at the pump) must be  
91 min. It is an average of both the Research (R) octane  
number and the Motor (M) octane number: [(R+M)/2].  
This is also known as ANTI-KNOCK INDEX.  
have the fuel tank filled only partially with unleaded  
regular and fill up with premium unleaded as soon  
as possible,  
Unleaded gasoline containing oxygenates such as  
Ethanol, IPA, IBA and TBA can be used provided the  
ratio of any one of these oxygenates to gasoline does not  
exceed 10%, MTBE not to exceed 15%.  
avoid full throttle driving and abrupt acceleration,  
The ratio of Methanol to gasoline must not exceed 3%  
plus additional cosolvents.  
do not exceed an engine speed of 3000 rpm, if the  
vehicle is loaded with a light load such as two  
persons and no luggage,  
Using mixtures of Ethanol and Methanol is not allowed.  
Gasohol, which contains 10% Ethanol and 90% unleaded  
gasoline, can be used.  
do not exceed 2/3 of maximum accelerator pedal  
position, if the vehicle is fully loaded or operating in  
mountainous terrain.  
These blends must also meet all other fuel requirements  
such as resistance to spark knock, boiling range, vapor  
pressure etc..

Gasoline additives  
Coolants  
A major concern among engine manufacturers is carbon  
build up caused by gasoline. Mercedes-Benz  
The engine coolant is a mixture of water and  
anticorrosion/antifreeze, which provides:  
recommends the use of only quality gasoline containing  
additives that prevent the build up of carbon deposits.  
corrosion protection,  
freeze protection,  
After an extended period of using fuels without such  
additives, carbon deposits can build up especially on the  
intake valves and in the combustion area, leading to  
engine performance problems such as:  
boiling protection (by increasing the boiling point).  
The cooling system was filled at the factory with a  
coolant providing freeze protection to approximately  
-35°F (-37°C) and corrosion protection.  
warm-up hesitation,  
unstable idle,  
knocking/pinging,  
misfire,  
If the antifreeze mixture is effective to -22°F (-30°C), the  
boiling point of the coolant in the pressurized cooling  
system is reached at approx. 266°F (130°C).  
The coolant solution must be used year round to provide  
the necessary corrosion protection and increase in the  
boil-over protection. You should have it replaced every  
3 years.  
power loss.  
Do not blend other specific fuel additives with fuel.  
They only result in unnecessary cost, and may be  
harmful to the engine operation.  
To provide the important corrosion protection, the  
solution must be at least 45% anticorrosion/antifreeze  
(equals a freeze protection to approx. - 22°F [-30°C]). If  
you use a solution that is more than 55% anticorrosion/  
antifreeze (freeze protection to approx. - 49°F [-45°C])-,  
Damage or malfunctions resulting from poor fuel  
quality or from blending specific fuel additives are not  
covered by the Mercedes-Benz Limited Warranty.

the engine temperature will increase due to the lower  
heat transfer capability of the solution. Therefore, do not  
use more than this amount of anticorrosion/antifreeze.  
Before the start of the winter season (or once a year in  
the hot southern regions), you should have the  
anticorrosion/antifreeze concentration checked. The  
coolant is also regularly checked each time you bring  
your vehicle to your authorized Mercedes-Benz Light  
Truck Center for service.  
If the coolant level is low, water and MB anticorrosion/  
antifreeze should be used to bring it up to the proper  
level (have cooling system checked for signs of leakage).  
The water in the cooling system must meet minimum  
requirements, which are usually satisfied by normal  
drinking water. If your are not sure about the water  
quality, consult your authorized Mercedes-Benz Light  
Truck Center.

Your vehicle contains a number of aluminum parts. The  
use of aluminum components in motor vehicle engines  
necessitates that anticorrosion/antifreeze coolant used  
in such engines be specifically formulated to protect the  
aluminum parts. (Failure to use such anticorrosion/  
antifreeze coolant will result in a significantly  
shortened service life.)  
Therefore the following product is strongly  
recommended for use in your vehicle: Mercedes-Benz

Consumer information  
Treadwear  
This has been prepared as required of all manufactures  
of passenger cars under Title 49, Code of U.S. Federal  
Regulations, Part 575 pursuant to the “National Traffic  
and Motor Vehicle Safety Act of 1966”.  
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 one-half  
(1 1/2) 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  
Uniform tire quality grading  
Quality grades can be found where applicable on the  
tire sidewall between tread shoulder and maximum  
section width. For example:  
variations in driving habits, service practices and  
differences in road characteristics and climate.  
Traction  
Tread wear 200 Traction AA  
Temperature A  
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.  
All passenger vehicle tires must conform to federal  
safety requirements in addition to these grades.  
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.

Temperature  
Warning!  
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  
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 excessive heat build up  
and possible tire failure.  
performance which all passenger vehicle 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.
