Replacing bulbs
Replacing bulbs
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. i
If 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.

Backup bulbs will be brought into use
when lamps malfunction. Observe the
messages in the multifunction display
(
