58 Safety and SecurityOccupant safetyWarning!
G
The service life of the passenger front airbag
extends to the date indicated on the label lo-
cated 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.
Warning!
G
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 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 it is properly posi-
tioned on your body (
page 62).
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 front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

the vehicle when the driver’s door is
opened. However, the engine must be
turned off.
When the SmartKey is inserted in the start-
er switch and the driver’s door is closed,
the steering wheel returns to the last set
position.The easy-entry/exit feature can be
switched on or off in the individual setting

trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated, the driver’s door is being opened
and the engine is turned off.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.

unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.

(page 35) and the head restraint fully
down (
page 36) and hold the switch-
es for approximately one second.
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
Do not interchange head restraints from
front and rear seat.
iTilt the seat backrest rearward for eas-
ier removal and installation of the head
restraints.
