Replacing bulbs
Notes on bulb replacement

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 following
lamps replaced at an authorized
Mercedes-Benz Center.

Additional turn signal lamps in the exte-
rior rear view mirrors

High mounted brake lamp

Bi-Xenon* lamps

Front fog lamps

Front side marker lamps
Warning!G
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.
!Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the
vehicle. Only have the LEDs replaced at an au-
thorized Mercedes-Benz Center.
