The red distance warning lamp
comes on while driving and you
hear a warning chime sound.
You are gaining too rapidly on the vehicle
ahead of you.
The distance warning system has recog-
nized a stationary obstacle on your probable
line of travel.
Apply the brakes immediately.
Carefully observe the traffic
situation. You may need to brake
or maneuver to avoid hitting an
obstacle.

The red SRS indicator lamp comes
on while driving.
There is a malfunction in the restraint systems.
The air bags or emergency tensioning device
(ETDs) could deploy unexpectedly or fail to
deploy unexpectedly in an accident.
Drive with added caution to the
nearest authorized
Mercedes-Benz Light Truck
Center.
Warning!
G
In the event a malfunction of the SRS is indi-
cated 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 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 result in
an accident and/or injury to you or to
others.

Front passenger airbag
enabled
See Operator’s Manual
Front passenger front air bag
is activated while driving even
though a child, small
individual, or object below
the system’s weight thresh-
old is on the front passenger
seat, or the front passenger
seat is empty. Objects on the
seat or forces acting on the
seat may make the system
sense supplemental weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (
page 65).
Switch off the ignition (
page 40).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Remove any other items from on and around the front passenger seat
and make sure the storage bag on the back of the front passenger seat
is empty.
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around the
seat, head restraints pushing against roof etc.). The system may recog-
nize such forces as supplemental weight and sense that an occupant on
the front passenger seat is of a greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 40).

Front passenger airbag
disabled
See Operator’s Manual
Front passenger front air bag is
deactivated while driving even
though an adult or someone
larger than a small individual is
occupying the front passenger
seat. Forces acting on the seat
may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (
page 65).
Switch off the ignition (
page 40).
Have the front passenger vacate the seat and exit the vehicle.
Adjust the seat in a height position (
page 44).
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged underneath, behind
or around the seat). Such forces may cause the system to sense that
an occupant of a lesser weight than actually present is on the front
passenger seat.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 40).

Possible solution
#
The battery is no longer charging.
Possible causes:
alternator malfunctioning
broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may be
operating with restricted capability.
Considerably greater brake pedal
force is required and the stopping dis-
tance is increased.
Stop the vehicle in a safe location or as
soon as it is safe to do so.
Apply the parking brake (
page 65).
Check the poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise the
engine will overheat due to an inoperative
water pump which may result in damage
to the engine. Notify an authorized
Mercedes-Benz Light Truck Center.
If it is intact:
Drive immediately to the nearest
authorized Mercedes-Benz Light Truck
Center. Adjust driving to be consistent
with reduced braking responsiveness.
