Working on the lighting system
When working on the lighting system, you
should always switch off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement on
xenon headlamps
Have any work on the xenon lighting system, in‐
cluding bulb replacement, performed only by a
service center. Due to the high voltage present
in the system, there is the danger of fatal injuries
if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar, or
hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Light-emitting diodes installed behind a cover
serve as the light source for controls, display el‐
ements and other equipment.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never stare
into the unfiltered light for several hours; other‐
wise, irritation of the retina could result.◀
Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.

the light switched on, increasing humidity forms,
e. g. water droplets in the light, have the service
center check this.
