Replacing bulbs
Important safety notes
Xenon bulbs
GDANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
th e Xenon bulb and touch the electrical con-
tacts . There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of th e Xenon bulb. Always have work on
th e Xenon bulbs carried out at a qualified spe-
cialist workshop.
If your vehicle is equipped with Xenon bulbs,
you can recognize th is 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 drive system. For this tobe
observed, the lights must be switched on
before the drive system is started.
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.
Other bulbs
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you changeabulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these component s to cool down before
changing a bulb.
104Replacing bulbs
Lights and windshield wipers

Do not use a bulb that has been dropped or if
its glass tube has been scratched.
The bulb may explode if:
Ryou touch it
Rit is hot
Ryou drop it
Ryou scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt- age.
Marks on the glass tube reduce the service
life of the bulbs. Do not touch the glass tube
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.
There are bulbs other than the Xenon bulbs
that you cannot replace. Only replace the
bulbs listed (
Ypage 105). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
