108 Instruments and Controls
If the windshield wiper lever is then
moved to OFF before the driver
door is opened or within 10 minutes,
the wipers will restart and move to
the base of the windshield.
If the ignition is changed to LOCK/
OFF while the wipers are performing
wipes due to windshield washing or
Rainsense, the wipers continue to
run until they reach the base of the
windshield.
Rainsense
If equipped with Rainsense, a
sensor located near the top center
of the windshield detects the
amount of water on the windshield
and automatically controls the
frequency of the windshield wiper.
When Rainsense is enabled, the
normal intermittent control operates
as a sensitivity control.
Keep this area of the windshield
clear of debris to allow for best
system performance.
AUTO : Move the windshield wiper
lever to AUTO. Turn the band on the
wiper lever to adjust the sensitivity.
Turn the band up for more
sensitivity to moisture.
Turn the band down for less
sensitivity to moisture.
Move the windshield wiper lever
out of the AUTO position to
deactivate Rainsense.
To enable or disable this feature,
see Rainsense Wipers under
Vehicle Personalization 0 147.

windshield.

normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
Windshield Washer
Pull the windshield wiper lever
toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
windshield wiper lever is released,
additional wipes may occur
depending on how long the
windshield washer had been
