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 collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen 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
windscreen with washer fluid after an auto- matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind- screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. 1

Vehicles with a rain sensor: in theÄor
Å position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the Åposition, the
rain sensor is more sensitive than in the Ä
position, causing the windscreen wipers to
wipe more frequently.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions. Replacing the wiper blades
