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 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
If your vehicle has this feature, the rear window defogger
uses a warming grid to clear fog from the rear window.
The button is located
on the center of the
instrument panel, near the
vehicle’s comfort controls.
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.
