5-6 Instruments and Controls
Rear Window
Wiper/Washer
WARNING
In freezing weather, do not use
your washer until the windshield
is warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
The rear wiper control is located on
the turn and lane change lever.
To turn the rear wiper on, slide the
lever to a wiper position.
(Off): Turns the wiper off.
(Rear Wiper Delay): Turns on
the rear wiper delay.
(Rear Wiper): Turns on the rear
wiper.
(Rear Wiper Wash): Press this
button on the end of the lever to
spray washer fluid on the rear
window. The wipers will clear the
rear window and either stop or
return to your preset speed. For
more washer cycles, press and hold
the button.
The rear window wiper/washer will
not operate if the liftgate or liftglass
is open or ajar. If the liftgate or
liftglass is opened while the rear
wiper is on, the wiper returns to the
parked position and stops.

Compass

The vehicle may have a compass in
the Driver Information Center (DIC).

Compass Zone

The zone is set to zone eight upon
leaving the factory. Your dealer will
set the correct zone for your
location.
Under certain circumstances,
such as during a long-distance,
cross-country trip or moving to a
new state or province, it will be
necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone is
not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
