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 is used properly.
There are two modes to clear fog or frost from the
windshield and side windows.
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 in extremely cold conditions. For best results,
clear all snow and ice from the windshield before
defrosting.
Turn the knob on the right of the climate control panel
to select the defog or defrost mode. The temperature
knob should be in the red area and the fan control
toward high.
- (Defog): With this setting, the outside air comes
out of both the floor and defroster outlets. Adjust
the temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting
to dehumidify the air.
1 (Defrost): This setting operates the defroster.
Most of the air comes out near the windshield,
with some going to the floor outlets and front side
windows. The air conditioning compressor may operate
in this setting to dehumidify the air.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
Some vehicles may have a rear window defogger.
< (Rear Window Defogger): Press this button to
turn the rear window defogger on or off. Be sure to clear
as much snow from the window as possible.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window and only works
when the ignition is in ON/RUN.
The rear window defogger turns off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
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.
