& WARNING
• The rain sensor is only intended to assist the driver. The driver
is still responsible for manually switching the wipers on according
to the visibility conditions.
• The windshield may not be treated with water-repelling wind­
shield coating agents. Unfavorable conditions, such as wetness,
darkness, low sun, can result in increased glare. Wiper blade
chatter is also possible.
• Properly functioning windshield wiper blades are required for

off . Activate the windsh ield wipers after the ignition is switched back
on by moving the windshield wiper lever to any position.
• Worn or dirty windshield wiper blades result in streaking. This can
affect the rain sensor* function . Check your windshield wiper blades
regularly .
• Th e washer fluid nozzles of the w indshield washe r system are
heated at low temperatures when the ignition is on. •
When stopping temporarily, e .g . at a traffic light, the set speed of
the windsh ield wipers is automatically reduced by one speed.•
