Wipe Parking
If the ignition is changed to LOCK/
OFF while the wipers are on LO, HI,
or INT, they will immediately stop.
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

280 Driving and Operating
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
3on the steering wheel to
adjust the following gap. When
pressed, the current gap setting
displays briefly on the instrument
cluster and HUD, if equipped.
Subsequent presses cycle the gap
button through three settings: Far,
Medium, or Near. The gap setting
will be maintained until it is
changed.
Since each gap setting corresponds
to a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a
vehicle detected ahead. Consider
traffic and weather conditions when
selecting the following gap. The
range of selectable gaps may not be
appropriate for all drivers and
driving conditions.
Changing the gap setting
automatically changes the alert
timing sensitivity (Far, Medium, or Near) for the Forward Collision
Alert (FCA) feature. See
Forward
Collision Alert (FCA) System 0290.
