Bulbs
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. See your autho-
rized Mercedes-Benz Center for headlamp
adjustment.
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.
iSubstitute bulbs will be brought into
use when lamps malfunction. Observe
the messages in the multifunction dis-
play (
page 392).

handling bulbs.
Your hands should be dry and free of oil
and grease.

Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in 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.
