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.
