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.

low the lamp to cool down before changing
a bulb.

Because of high voltage in Bi-Xenon lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
