If it is necessary to switch on the windshield
wipers in dry weather conditions, alwaysu se

windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratc hthe windshield.
For this reason, you should alwayss witch off
the windshield wipers in dry weather.
