WARNING
The windscreen will not longer be wiped prop-
erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident .Replace
the wiper blades twice ayear, ideally in spring
and autumn.
! 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 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. Combination switch

For this reason, you should alway sswitch
off the windscreen wipers in dry weather.
In the ÄorÅ position ,the appropriate
wiping frequenc yisset automatically accord-
ing to the intensity of the rain. In the Å
position ,the rain sensor is more sensitive
than in the Äposition ,causing the wind-
