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 a year, ideally in spring
and autumn.
! Do not operate the windscreen wipers
when the windscreen/rear window is dry,
as this could damage the wiper blades.
Moreover, dust that has collected on the
windscreen/rear window can scratch the
glass if wiping takes place when the wind-
screen/rear window is dry.
If it is necessary to operate the windscreen
wipers/rear window wiper in dry weather
conditions, always use washer fluid.
! If the windscreen wipers leave smears on
the windscreen/rear window after the vehi-
cle has been washed in an automatic car
wash, this may be due to wax or other res-
idue. Clean the windscreen/rear window
with washer fluid after an automatic 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. Combination switch
