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 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.
-
(Defog): This mode directs the air between the
windshield, side windows, instrument panel outlets and
the floor outlets. The air-conditioning compressor
will run automatically in this setting without pressing
A/C, unless the outside temperature is at or below
freezing.
1
(Defrost): This mode directs the air to the
windshield, instrument panel outlets and the side
windows. The air-conditioning compressor will run
automatically in this setting without pressing A/C, unless
the outside temperature is at or below freezing.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to clear
fog from the rear window.
The rear window defogger
button is located on the
center of the instrument
panel, above the audio
system. The defogger does
not operate with the rear
liftglass opened.
The rear window defogger will only work when the
ignition is in ON.
=
(Rear Defogger): Press the defogger button to turn
the rear window defogger on or off. An indicator light
in the button will come on to let your know that the rear
window defogger is activated. Be sure to clear as
much snow from the rear window as possible.
