Move the windshield wiper lever to the corre-
sponding position:
@ - Windshield wiper off

wiper intervals, move the switch ® to the
left/right. In vehicles with a rain sensor*, the
windshield wipers are activat ed automatically
starting at a speed of 2 mph (4 km/h) . The
higher the sensitivity of the rain sensor* is set
(switch @ to the right), the earlier the wind-
shield wipers react to moisture on the wind-
shield.

seconds of the afterwipe operation . The after-
wipe function is reactivated the next time the
ignition is swi t ched on.

er system* only functions when the light is
switched on. The headlights are automatically
cleaned the first time and every fifth time the
lever is moved to position @ . They are also
cleaned every time you hold the lever in posi-
tion ® for longer than 2 seconds.
A WARNING
- The rain sensor is only intended to assist
the driver . The driver is still responsible
for manually switching the wipers on ac-
cording to the visibility conditions.
- The windshield may not be treated with
water-repelling windshield 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 a clear view and
safe driving
q page 57, Replacing
windshield wiper blades.
(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 0). This helps to prevent unin-
tentional switch ing on and damage to
the windshield wiper system.
(D Tips
- The windshield wipers are switched off
when the ignition is turned 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.
