Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Light Truck Center for
headlamp adjustment.Front lamps
iBackup bulbs will be brought into use
when the following lamps malfunction:

Turn signal lamps


Parking lamps


Tail lamps
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of
high humidity, driving the vehicle a dis-
tance with the lights on should clear up
the fogging.

ing a bulb.
Keep bulbs out of reach of children.

Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
