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 the windshield. Use the defog mode to clear the inside of the windshield of fog or moisture and warm the passengers. Use the defrost mode to remove fog or frost from the outside of the windshield more quickly. 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. - (Defog): Air is directed 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 32°F (0°C). The rear window defogger will only work when the ignition is in the ON position. 1 (Defrost): Air is directed 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 32°F (0°C). Do not drive the vehicle until all the windows are clear. 154 = (Rear Defogger): Press the defogger button to turn the rear window defogger on or off.
