Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or 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 or frost
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.
É
(Defog): Press the MODE button until the defog
symbol appears on the automatic climate control system
display.
This mode directs most of the air to the windshield and
the floor outlets. A small amount of air is also directed
to the outboard outlets for the side windows.
To help clear the side windows quickly, do the following:
1. Select the bi-level mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the temperature.

(Defrost): Press the defrost button to select the
defrost function.
Pressing this button directs the air to the windshield and
the outboard outlets for the side windows.
To help clear the windshield quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
Do not drive the vehicle until all windows are clear.
To cancel defrost, press the MODE or AUTO buttons. If
you press the AUTO button, the system will operate
automatically.
Rear Window and Outside Mirror
Defogger
Your vehicle has a rear window and outside mirror
defogger. This feature will only work when the ignition is
turned to ON.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before using
this feature, clear as much snow from the rear
window as possible.
