It remains entire­
ly the driver's responsibility to monitor
outside weather conditions and to man­
ually activate the wipers as soon as rain
or drizzle reduces visibility through the
windshield.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi·
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­

(D Note
- In the case of frost, check whether the
windshield wiper blades are frozen to the windshield. Switching on the wind­
shield wipers can damage the wiper
blades!
- Prior to using a car wash, the windshield
wiper system must be switched off (lever
in position @). This helps to prevent un­
intentional switching on and damage to
the windshield wiper system.
- Do not use the wipers to clear a frosted
window . Using the wipers as a conven­
ient ice scraper will destroy the wiper
blades.

- The windshield wipers are switched off
when the ignition is off . Activate the
windshield wipers after the ignition is
switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
result in streaking. This can affect the
rain sensor function. Check your wind­
shield wiper blades regularly.
- The washer fluid nozzles of the wind­
shield washer 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 wind­
shield wipers is automatically reduced by
one speed.
