It is dangerous to shift the selector lever out
ofP 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 en-
gine is idling normally and when your right
foot is firmly on the brake pedal.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
More information can be found in the
“Practical hints” section (
page 242).

55 Safety and Security
Occupant safety
Airbags
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Light Truck Center immedi-
ately 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 unexpect-
edly and unnecessarily which could also re-
sult in injury.
Improper work on the restraint systems can
lead to unintentional deployment or opera-
tional failure.
All work on these systems should therefore
only be carried out by an authorized
Mercedes-Benz Light Truck Center.
Warning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, which may cause significant injuries.
However, no system available today can to-
tally eliminate injuries and fatalities.
The activation of the SRS temporarily releas-
es 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 tempo-
rary breathing difficulty for people with asth-
ma 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!
G
The service life of the front passenger 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 Mer-
cedes-Benz Light Truck Center at that time
and replaced when necessary.

56 Safety and SecurityOccupant safetyWarning!
G
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.

58 Safety and SecurityOccupant safetySafety guidelines for the seat belt,
emergency tensioning device and
airbag
When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.Warning!
G


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 in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.


No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front airbag cov-
er, or door trim panels, 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.).


Airbags and ETDs are designed to func-
tion on a one-time-only basis. An airbag
or emergency tensioning device (ETD)
that was activated must be replaced.


Do not pass belts over sharp edges.
They could tear.


Do not make any modification that could
change the effectiveness of the belts.


An airbag system component within the
steering wheel gets hot after the airbag
has inflated. Do not touch.


Improper work on the system, including
incorrect installation and removal, can
lead to possible injury through an unin-
tended activation of the SRS.


In addition, through improper work
there is a risk of rendering the SRS inop-
erative or causing unintended airbag de-
ployment. Work on the SRS must
therefore only be performed by an au-
thorized Mercedes-Benz Light Truck
Center.


For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Light Truck Center.


Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.
