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:

fogged up on the inside as a result of
high humidity, driving the vehicle a dis-
tance with the lights on should clear up
