exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.

important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See your autho-
rized Mercedes-Benz Center for headlamp
adjustment.

low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you

touch or move it when hot


drop the bulb

Wear eye and hand protection.
Because of high voltage in Bi-Xenon lamps,
it is dangerous to replace the bulb or repair
the lamp and its components. We recom-
mend that you have such work done by a
qualified technician.
