Replacing 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. Contact an 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 humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.iSubstitute bulbs will be brought into use
when the following lamps malfunction:
Brake lamps
Rear fog lamps
Front parking lamps
Tail lamps
Turn signal lamps
Read and observe messages in the multifunction
display (
page 612).

Replacing bulbs
Notes on bulb replacementOnly 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, contact an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:
the Bi-Xenon lamps
the front turn signal lamps
the front fog lamps
the additional turn signal lamps in the
exterior rear view mirrors
the parking and standing lamps
the front side marker lamps
the high mounted brake lamps
the brake, tail and rear standing lamps
the rear side marker lamps
the rear fog lamp
the rear turn signal lamps
the rear side marker lamps
the license plate lamps
Replacing bulbs for front lamps
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to M
(
page 371).
Open the hood (page 541).
Warning!G
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.
!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.
iHave the headlamp adjustment checked
regularly.
