power assistance for the brake and the
steering system. 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.
Warning!G
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury or
damage to the vehicle drivetrain as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:

Keep right foot on brake pedal.

Pull the parking brake lever up as many
notches as possible.

Move the gear selector lever to park
positionP.

Slowly release brake pedal.

page 27) comes on:

for about 4 seconds when you turn the
SmartKey in the starter switch to
position1.

for about 4 seconds when you start the
engine by turning the SmartKey.The SRS components are in operational
readiness if the 1indicator lamp is not

detected if the 1 indicator lamp:

fails to go out after approximately
4 seconds.

does not come on at all.

comes on after the engine was started
or while driving.

69 Safety and Security
Occupant safety
Warning!G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, emergency tensioning
devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with in-
terconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.
Air bags or emergency tensioning devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the de-
celeration threshold for air bag deployment
is exceeded. Therefore, never modify the re-
straint systems. Do not tamper with elec-
tronic components or their software.
Warning!G
In the event that the 1indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Light Truck Center immedi-
ately to have the system checked; otherwise
the SRS may not deploy 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.
In addition, improper work on the SRS cre-
ates a risk of rendering the SRS inoperative
or causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians. Contact
an authorized Mercedes-Benz Light Truck
Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact a local authorized Mercedes-Benz
Light Truck Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
