WARNING
The windscree nwill 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
scratcht he 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. Cleant he
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 scratcht he wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. Combination switch
