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 by 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 by an
authorized Mercedes-Benz Center.

vehicle’s on-board electronics have
status0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
Warning!G
Wiper blades are components that are sub-
ject to wear and tear. Change the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the windows will not be
properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.
!Never open the hood when the wiper arms
are folded forward.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
!Do not pull on the wiper blade inserts. They
could tear.
!Hold on to the wiper arm. If released, the
force of the impact from the tensioning spring
could crack the windshield.
