Windshield wipers without rain sensor*
At speeds of approximately 105 mph
(170 km / h) the wiper switches automati-
cally to continuous wiping. Always obey lo-
cal speed limits.Windshield wipers with rain sensor*
A rain sensor automatically controls the
windshield wipers depending on how wet
the windshield is.
Switch on ignition.
Set the wiper switch to position1
(page 51).
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor which monitors the wetness of
windshield.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
iWhen intermittent wiping is on and the
key is turned from position1 to
position2 in the steering lock
(page 33), and kept in that position
for longer than two seconds, the wipe
interval will be set to approximately
five seconds.
!Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.

off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
