Defogging and Defrosting Fog or frost 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. 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. When either of these modes are selected, the system runs the air conditioning compressor and cancels the recirculation mode to dry the air. For best results, clear all snow and ice from the windshield before defrosting. Turn the right knob to select the defog or defrost mode. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. The rear window defogger only works when the ignition is in ON/RUN. < (Rear): Press this button to turn the rear window defogger on or off. An indicator light on the button comes on to show that the rear window defogger is activated. The rear window defroster stays on for about 10 minutes if the vehicle remains at slower vehicle speeds or until the button is pressed, or unless the ignition is turned to ACC/ACCESSORY or LOCK/OFF. If turned on again, the defogger only runs for about five minutes before turning off again. At higher vehicle speeds, the defogger may stay on continuously. The defogger can always be turned off by pressing the button again or by turning off the ignition. - (Defog): This mode directs half of the air to the windshield and the side window outlets, and half to the floor outlets. 0 (Defrost): This mode directs most of the air to the windshield and the side window outlets, with some air directed to the floor outlets. 3-21
