56 Getting startedDriving
Intermittent wiping
Set the wiper switch to positionI.
Single wipe
Press switch briefly in the direction of
arrow1.
The windshield wipers wipe one time
without washer fluid.Wiping with windshield washer fluid
Push switch in the direction of
arrow1 past the resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield/rear window
washer system and headlamp cleaning
system*” (
page 333).
!Vehicles with rain sensor*:
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.
Do not operate the wipers when the
windshield is dry. Dust that accumu-
lates on a windshield might scratch the
glass and/or damage the wiper blades
when wiping occurs on a dry wind-
shield. If it is necessary to operate the
wipers in dry weather conditions, al-
ways operate the wipers with wind-
shield washer fluid (
page 56).
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
