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

In the 0001or0002 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0002 position, the rain sensor is more
