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 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. For best results, clear all snow and ice from the windshield before defrosting. Use a temperature setting that provides warm air. The warmer the air the quicker the windows will clear. To prevent fogging on the inside of the windows in modes other than floor/defog and defrost, make sure the air conditioning compressor, if the vehicle has one, is on and recirculation mode is off. 0 (Defrost): Turn the right knob on the control panel to this mode to direct most of the air to the windshield, and the side window outlets. When you select this mode, the system runs the air conditioning compressor unless the outside temperature is near 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 remove fog or frost from the rear window. Be sure to clear as much snow from the rear window as possible. An indicator light on the knob will come on to let you know that the rear window defogger is activated. The rear window defogger will turn off about fifteen minutes after the knob is pressed. If turned on again, the defogger will run for about seven and one-half minutes before turning off. If the vehicle speed is greater than 50 mph (80 kph) and the rear defogger is active, it will remain on as long as the speed is greater than 50 mph (80 kph). The defogger can also be turned off by pressing the knob again or by turning off the engine. / (Floor/Defog): Turn the right knob on the control panel to this mode to direct the air to the windshield, the side window outlets, and to the floor outlets. When you select this mode, the system runs the air conditioning compressor unless the outside temperature is near freezing or below. 125
