Safety notes
Safe vehicle operation depends on proper
exterior lighting and signaling to a large
degree.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals. Contact an
authorized Mercedes-Benz Center for
headlamp adjustment. G
Warning!
The bulbs in the tail lamps cannot be replaced
individually. The tail lamp bulbs are under
pressure and could explode during an attempt
to replace them.
If the tail lamps are malfunctioning, have them
replaced at an authorized Mercedes-Benz
Center.
i If the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging. Replacing bulbs for front lamps
G
Warning!
Do not remove the cover for the Bi-Xenon
headlamp. Because of high voltage in Xenon
lamps, it is dangerous to replace the bulb or
repair the lamp and its components. It is
recommended to have such work done by a
qualified technician.
i Replacing the bulbs for the front lamps is
a technically complex process. Have such
work done by an authorized Mercedes-
Benz Center. Replacing bulbs
