Changing bulbs
Important safety notes
GDANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the 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 the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
!Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-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 low-
beam headlamps must be switched on before
starting the engine.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make
sure that these function correctly at all times.
Have the headlamp setting checked regularly.
RAlways switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
RDo not touch the glass tube of new bulbs with your bare hands. Always use a clean, lint-free
cloth or only touch the base of the bulb when
installing.
Even minor contamination can burn into the
glass surface and reduce the service life of the
bulbs.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could explode.
ROnly use bulbs in closed lamps which have
been designed for this purpose.
ROnly use spare bulbs of the same type and
with the prescribed voltage
RProtect the bulbs from moisture when in use.
If the new bulb still does not light up, consult a
qualified specialist workshop.
RHave the LEDs and bulbs of the following
lamps changed at a qualified specialist work-
shop:
-the additional turn signals in the exterior
mirrors
-the high-mounted brake lamp
-LED daytime running lamps (Bi-Xenon
headlamps)
-Bi-Xenon lamps (Bi-Xenon headlamps)
-front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.

Windshield wipers
Switching the windshield wiper
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windshield can scratch the glass
if wiping takes place when the windshield is
dry. If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Vehicles with rain/light sensor:
Switch the wipers off in dry weather. Other-
wise, dirt or optical effects may cause unde-
sired windshield wiper sweeps. This could
then damage the windshield wiper blades or
scratch the windshield.
The windshield will no longer be wiped properly
if the wiper blades are worn. Replace the wiper
blades twice a year (
Ypage 97), ideally in
spring and fall.

briefly to the pressure point in the direction of arrow :.
XTo wipe with washer fluid: press the com-
bination switch beyond the pressure point in
