(Defrost): Pressing the defrost button directs most
of the air to the windshield, with some air directed to the
side windows and outboard panel outlets. In this mode,
the system will automatically turn off recirculation and run
the air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode.
This mode may also cause the fan speed and air
temperature to increase.

Rear Window Defogger

The rear window defogger uses a warming grid to
remove fog or frost from the rear window.

See "Personal Settings Menu" under Vehicle
Personalization on page 2-53 for additional information.

(Rear Window Defogger): Press this button to
turn the rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
The rear window defogger will turn off about 10 minutes
after the button is pressed, or if the vehicle's speed
is above 30 mph (48 km/h), the rear defogger will stay
on continuously. If turned on again, the defogger
will only run for about five minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
rear window defogger button is on.
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.
