Important safety notes
G
WARNING
Bulbs, lamps and connectors can get very
hot when operating. If you change a bulb,
you could burn yourself on these compo-
nents. There is a risk of injury.
Allow these components to cool down
before changing a bulb. !
Make sure the bulbs are always securely
installed.
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.
Observe the following notes when changing a
bulb:
R Always switch off the ignition before replac-
ing bulbs in the lighting system. This will
prevent a short circuit.
R Wear gloves and eye protection when
changing a bulb.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube. The
bulb could may explode.
R A bulb could explode if:
- you touch it
- it is hot
- you drop it
- you scratch or score it
R Marks on the glass tube shorten the operat-
ing life of a bulb. Do not touch the glass
tube with your bare hands. If necessary,
clean the glass tube when cold with alcohol
or spirit. Then rub off the glass tube with a
clean, lint-free cloth.
R Make sure that bulbs are protected from
moisture when operating and that they do
not come into contact with liquids. Make
sure that seals are seated correctly and
replace damaged seals.
R Check the contacts for signs of corrosion
and clean these if required.
R Only operate bulbs in closed lamps which
have been designed for this purpose.
R Only use spare bulbs of the same type, with
the prescribed voltage and the correct wat-
tage.
R If the new bulb does not light up, consult a
qualified specialist workshop. Replacing bulbs

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 collected 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 residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the wind-
shield.
For this reason, you should always switch
off the windshield wipers in dry weather. 1

set to low sensitivity)
3 Å Intermittent wipe, high (rain sensor
set to high sensitivity)
4 ° Continuous wipe, slow
5 ¯ Continuous wipe, fast
B î 1st pressure point – single wipe; 2nd

X Turn the key to position 1 or 2 in the igni-
tion lock.
X Turn the í wiper switch to the corre-
sponding position.
In the Ä or Å
positions, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive to
precipitation than in the Ä position, caus-
ing the windshield wipers to wipe more fre-
quently.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blades can
be found under "Replacing wiper blades"
