with your bare hands. If necessary, clean the
glass tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
Xenon bulbs
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure that these function correctly at all times.
Have the headlamp setting checked regularly.
LED lamps
You can replace neither Xenon bulbs nor LED
bulbs. Have LED bulbs changed at a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Before changing bulbs
Have the following bulbs replaced at a quali-
fied specialist workshop:
R Additional turn signals in the exterior mir-
rors
R High-mounted brake lamp
R High-beam/low-beam headlamps (Xenon
bulbs)
R Daytime running lamps
R Parking lamps/standing lamps
R License plate lamp
i Individual segments of the license plate
lamp LEDs may fail without a display mes-
sage appearing in the multifunction dis-
play. Regularly check the license plate
lamp. If necessary, visit a qualified special-
ist workshop. You can replace the following bulbs:
R Fog lamp/cornering light with fog lamp
function
R Turn signal lamp (front)
R Brake/tail lamp
R Turn signal lamp (rear)
R Tail lamps/standing lamps
R Backup lamp
R Rear Fog Lamp
R Side marker lamps
Other bulbs
There are bulbs other than the Xenon bulbs
that you cannot replace yourself. Only replace the bulbs listed (Y page 109). Have the bulbs
that you cannot replace yourself replaced at a
qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint- free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult a qualified specialist workshop.
