Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. The rear
window defogger will only work when the engine
is running.
= (Rear Window Defogger): Press to turn the rear
window defogger on and off. Be sure to clear as much
snow from the rear window as possible.
The rear window defogger turns off about 20 minutes
after the button is pressed. If turned on again, the
defogger only runs for about 20 minutes before turning
off. The defogger can also be turned off by turning
off the engine.
The heated outside rearview mirrors, help to clear fog or
frost from the surface of the mirror when the rear window
defog button is pressed.
Do not drive the vehicle until all the windows are clear.
Notice: Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere anything
to the defogger grid lines in the rear glass. These
actions may damage the rear defogger. Repairs
would not be covered by your warranty.
Sensors
The solar sensor on the vehicle monitors the solar heat
and the air inside of the vehicle. This information is used
to maintain the selected temperature by initiating needed
adjustments to the temperature, the fan speed, and the
air delivery system. The system may also supply cooler
air to the side of the vehicle facing the sun. The
recirculation mode will also be activated, as necessary.
Do not cover the solar sensor located in the center of the
instrument panel, near the windshield, or the system will
not work properly.
Outlet Adjustment
Use the thumbwheels located between the center
outlets to open and close the outlets. Move the lever
in the center of each air outlet to adjust the direction
of the airflow.
( (Heated Seats): Press to turn the driver or
passenger heated seats on and off. See Heated
Seats on page 1-3 for additional information.
