407 Practical hints
Replacing bulbs
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center:
Additional turn signals in the exterior
rear view mirrors
High mounted brake lamp
Bi-Xenon* lamps
Front fog lamps
Front side marker lamps
Parking and standing lamps (vehicles
with Bi-Xenon* headlamps only)
Rear lamps (except license plate
lamps)
Replacing bulbs for front lamps
1Housing cover for low beam halogen or
Bi-Xenon* headlamp
2Housing cover for high beam head-
lamp/high beam flasher bulb and for
parking and standing lamp bulb3Bulb socket for turn signal lamp bulb
4Bulb holder of high beam bulb
5Bulb socket for parking and standing
lamp bulb
6Bulb holder of low beam bulb
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to
positionM (
page 128).
Open the hood (
page 286) (except
for side marker lamps).
!
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.
Warning!
G
Do not remove the cover1 for the Bi-Xe-
non* headlamp. 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.
