88 INSTRUMENTS AND CONTROLS
Rainsense
If equipped with Rainsense, a sensor
near the top center of the windshield
detects the amount of water on the
windshield and controls the frequency
of the windshield wiper. To turn this
feature on or off, see“Rainsense
Wipers ”under Vehicle Personalization
0 116.
Keep this area of the windshield clear
of debris to allow for best system
performance.
AUTO : When enabled, move the
windshield wiper lever to AUTO. Turn
the
Oband 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.
Wiper Arm Assembly Protection
When using an automatic car wash,
move the windshield wiper lever to
OFF. This disables the automatic
Rainsense windshield wipers.
With Rainsense, if the transmission is
in N (Neutral) and the vehicle speed is
very slow, the wipers will
automatically stop at the base of the
windshield.
The wiper operations return to normal
when the transmission is no longer in
N (Neutral) or the vehicle speed has
increased.
f: 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 activated. See
Washer Fluid
0 252 for information on filling the
windshield washer fluid reservoir.
Compass
The vehicle has a compass display on
the Driver Information Center (DIC).
The compass receives its heading and
other information from the Global
Positioning System (GPS) antenna,
StabiliTrak/Electronic Stability Control
(ESC), and vehicle speed information.
The compass system is designed to
operate for a certain number of miles
or degrees of turn before needing a
signal from the GPS satellites. When
the compass display shows CAL, drive
the vehicle for a short distance in an
open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS
signal is restored and provide a
heading again.
