Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield. Use the defog mode to clear the
windows of fog or moisture and warm the passengers.
Use the defrost mode to remove fog or frost from
the windshield more quickly.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):This mode directs the air between the
windshield and oor outlets with some air supplied to the
outboard panel outlets and side window defogging
outlets. When you select this mode, the system turns off
recirculation and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode is cancelled when you enter
defog mode. If you select recirculation while in defog
mode, it will be cancelled after 10 minutes.
If you have fogging on the side windows, remain in
defog or defrost mode until they clear.
0(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.
The rear window defogger will only work when the
ignition is in ON or during remote start, if programmed.
See “Personal Settings Menu” underVehicle
Personalization on page 2-47for 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.
