Replacing bulbs
Important safety notes
G
WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a
bulb, you could burn yourself on these com-
ponents. There is a risk of injury.
Allow these components to cool down before
replacing the bulb.
Do not use a bulb if it has been dropped or if its
glass tube has been scratched.
The bulb may explode if:
R
you touch it
R
it is hot
R
you drop it
R
you scratch it
Use bulbs only in closed lamps that have been
designed for this purpose. Fit only spare bulbs of
the same type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulb. 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 operation.
Do not allow bulbs to come into contact with
liquids.
Replace only the bulbs listed (Y page 112).
Have the bulbs that you cannot change yourself
replaced at a qualified specialist workshop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb does not light up either, consult
a qualified specialist workshop.
Headlamps 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.
Vehicles with LED headlamps: the light clus-
ters of your vehicle are equipped with LED light
bulbs. Do not replace your vehicle's bulbs your-
self. Contact a qualified specialist workshop
with the necessary specialist knowledge and
tools to carry out the work required.

Windscreen wipers
Switching the windscreen wipers on/
off
!
Do not operate the windscreen wipers when
the windscreen is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected on the windscreen can scratch the
glass if wiping takes place when the wind-
screen is dry.
If it is necessary to switch on the windscreen
wipers in dry weather conditions, always
operate them using washer fluid.
!
If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may be
due to wax or other residue. Clean the wind-
screen with washer fluid after an automatic
car wash.

!
Vehicles with a rain sensor: if the wind-
screen becomes dirty in dry weather condi-
tions, the windscreen wipers may be activa-
ted inadvertently. This could damage the
windscreen wiper blades or scratch the wind-
screen.
For this reason, you should always switch off
the windscreen wipers in dry weather.
Vehicles with a rain sensor: in the Ä or Å
position, the appropriate wiping frequency is
automatically set according to the intensity of
the rain. In the Å position, the rain sensor is
more sensitive than in the Ä position, caus-
ing the windscreen wiper to wipe more fre-
quently.
If the wiper blades are worn, the windscreen will
no longer be wiped properly. This could mean
you are unable to observe the traffic conditions.
