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 Center for headlamp ad-
justment.
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.

use when the following lamps malfunc-
tion:
