350 Practical hintsReplacing bulbs
Replacing bulbsSafe 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.

Warning!

Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
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


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.

352 Practical hintsReplacing bulbs

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
come on, visit an authorized
Mercedes-Benz Center.


Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Center.
