WARNING
Wiper blades are components that are subject
to wea rand tear. Replace the wipe rblades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash. Combination switch

! Intermittent wiping with rain sensor: due
to optical influences and the windshield

the windshield wipers may be activated
inadvertently. This could the ndamage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the 0004or0005 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0005 position, the rain sensor is more
sensitive than in the 0004position, causing
the windshield wipers to wipe more
frequently. Replacing the wiper blades
