AdjustingSeatsWarning!
G
All seat, head restraint, steering wheel, and 
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before 
the vehicle is put into motion.Warning!
G
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 re-
clined 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 se-
rious or fatal injuries.
The seat back and seat belts provide the 
best restraint when the wearer is in an up-
right position and belts are properly posi-
tioned on the body. Your seat must be 
adjusted so that you can correctly fasten 
your seat belt (
page 40).
Never place hands under the seat or near 
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the 
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 ve-
hicle, or with access to an unlocked vehicle. 
Unsupervised use of vehicle equipment may 
cause an accident and/or serious personal 
injury.
Warning!
G
Children 12 years old and under must never 
ride in the front seat, except in a 
Mercedes-Benz authorized BabySmart
TM 
compatible child seat, which operates with 
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger side front 
airbag when it is properly installed. Other-
wise they will be struck by the airbag when 
it inflates in a crash. If this happens, serious 
or fatal injury will result.
According to accident statistics, children 
are safer when properly restrained in the 
rear seating positions than in the front seat-
ing positions. Infants and small children 
must be seated in an appropriate infant or 
child restraint system, which is properly se-
cured with the vehicle's seat belt and top 
tether strap, or secured via lower anchors 
and top tether strap, fully in accordance 
with the child seat manufacturer's instruc-
tions.

Seat fore and aft adjustment
Press the switch forward or back in the 
direction of arrow2.
Adjust a comfortable seating position 
that still allows you to reach the accel-
erator/brake pedal safely. The position 
should be as far rearward as possible, 
consistent with ability to properly oper-
ate controls.
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.
iWhen moving the seat, be sure that
there are no items in the footwell or 
behind the seats
the cup holder next to the armrest 
is removed (
page 178)
the cup holder in the front passen-
ger footwell is folded closed 
(page 178)
Otherwise you could damage the seats 
and/or cup holders.

DrivingFastening the seat beltWarning!
G
Do not lay any objects in the driver’s foot-
well. Be careful that floor mats or carpets in 
the driver’s footwell have sufficient clear-
ance for the pedals.
During sudden driving or braking maneuvers 
the objects could get caught between the 
pedals. You could then no longer brake or 
accelerate.Warning!
G
Always fasten your seat belt before driving 
off. Always make sure your passengers are 
properly restrained, even those sitting in the 
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your 
risk of injuries and their likely severity in an 
accident. You and your passenger should al-
ways 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.
In the same crash, the possibility of injury or 
death is lessened if you are wearing your 
seat belt. The airbags can only protect as ex-
pected if the occupants are using their seat 
belts (
page 54).
Warning!

Children 12 years old and under must never 
ride in the front seat, except in a 
Mercedes-Benz authorized BabySmart

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 and top tether strap, or secured via 
lower anchors and top tether strap, fully in 
accordance with the child seat manufactur-
er's instructions.

Never ride in a moving vehicle with the back-
rest reclined. Sitting in an excessively re-
clined 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 se-
rious 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.
Warning!

Never let more people ride in the vehicle 
than there are seat belts available. Be sure 
everyone riding in the vehicle is correctly re-
strained with a separate seat belt - even 
those in the rear.Warning!

To reduce the risk of injury when the front 
airbags inflate, it is very important for the 
driver and passenger to always be in a prop-
erly seated position and to wear your seat 
belt.
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 (
page 60).
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. Oc-
cupants who are unbelted, out of position or 
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great 
force in the blink of an eye:
Sit properly belted in an upright position 
with your back against the backrest.
Adjust the driver seat as far as possible 
rearward, still permitting proper opera-
tion of vehicle controls. The distance 
from the center of the driver’s breast-
bone to the center of the airbag cover on 
the steering wheel must be at least ten 
inches (25 cm) or more. You should be 
able to accomplish this by a combina-
tion of adjustments to the seat and 
steering wheel. If you have any prob-
lems, please see your authorized 
Mercedes-Benz Light Truck Center.
Do not lean with your head or chest 
close to the steering wheel or dash-
board.
Keep hands on the outside of steering 
wheel rim. Placing hands and arms in-
side the rim can increase the risk and 
potential severity of hand/arm injury 
when driver front airbag inflates.
Adjust the passenger seat as far as pos-
sible rearward from the dashboard when 
the seat is occupied.
Always sit upright, properly use the seat 
belts and appropriate size infant or child 
restraint system.
Children 12 years old and under must 
never ride in the front seat, except in a 
Mercedes-Benz authorized 
BabySmart
TM compatible child seat, 
which operates with the BabySmart
TM 
system installed in the vehicle to deacti-
vate 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, seri-
ous or fatal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible 
to make the buyer aware of these points. Be 
sure to give the buyer this Operator’s 
Manual.

Warning!
G
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 passenger seat 
of your vehicle, you must properly use a 
BabySmart
TM child restraint which will turn 
off the passenger side front airbag 
(
page 65). 
iAirbags are designed to activate only in 
certain frontal (front airbags) impacts 
which exceed preset thresholds.
Only during these types of impacts, if of 
sufficient severity to meet the deploy-
ment thresholds, will they provide their 
supplemental protection.
The driver and passenger should al-
ways wear their seat belts. Otherwise it 
is not possible for the airbags to pro-
vide their supplemental protection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other 
accidents, the airbags will not be acti-
vated. The driver and passengers will 
then be protected by the fastened seat 
belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid 
wearing your seat belt.
Your vehicle was originally equipped 
with airbags that are designed to acti-
vate in certain impacts exceeding a 
preset threshold to reduce the poten-
tial and severity of injury. It is important 
to your safety and that of your passen-
ger that you replace deployed airbags 
and repair any malfunctioning airbags 
to ensure that the vehicle will continue 
to provide supplemental crash protec-
tion for occupants.

After starting the engine, the seat belt non-
usage warning lamp blinks for a brief peri-
od to remind the driver and passengers to 
fasten their seat belts.
The use of seat belts and infant and child 
restraint systems is required by law in all 
50 states, the District of Columbia and all 
Canadian provinces. Even where this is not 
the case, all vehicle occupants should have 
their seat belts fastened whenever the ve-
hicle is in motion.
Information on fastening seat belts is 
found in the “Getting started” section 
(
page 40).

Children in the vehicle
If an infant or child is traveling with you in 
the vehicle:
Secure the child using an infant or child 
restraint appropriate to the age and 
size of the child and recommended for 
use by Mercedes-Benz.
Ensure that the infant or child is prop-
erly secured by a belt at all times while 
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any 
Mercedes-Benz Light Truck Center.
Infant and child restraint systems
Use only a BabySmart
TM1
 compatible child 
restraint for the front passenger seat in 
this vehicle.We recommend that all infants and 
children be properly restrained at all times 
while the vehicle is in motion. All lap-shoul-
der belts except the driver’s seat belt have 
special seat belt retractors for secure fas-
tening of child restraints.
To fasten a child restraint, follow manufac-
turer’s instructions for mounting child re-
straints. 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.
To deactivate, release seat belt buckle and 
let seat belt retract completely. The seat 
belt can again be used in the usual man-
ner.
Warning!
G
An emergency tensioning device (ETD) that 
was activated must be replaced.
When scrapping the emergency tensioning 
device, our safety instructions must be fol-
lowed. These are available at your autho-
rized Mercedes-Benz Light Truck Center.!Do not place objects heavier than 
20 lbs (9 kg) on the front passenger 
seat. This could cause the front airbag 
on the front passenger side to deploy in 
a crash which exceeds the system's de-
ployment threshold.
