Safe vehicle operation depends on proper
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. Contact your au-
thorized Mercedes-Benz Center for head-
lamp adjustment.Front lampsi
If the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.

Only use 12-volt bulbs of the same type
and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not light
up, visit an authorized Mercedes-Benz
Center.
Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized

Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced by an autho-
rized Mercedes-Benz Center.
Warning!
G
Do not remove the cover1 for the
Bi-Xenon* headlamp. Because of high
voltage in Bi-Xenon* lamps, it is dangerous
to replace the bulb or repair the lamp and its
components. We recommend that you have
such work done by a qualified technician.
