1 (Defrost): This mode directs most of the air to the windshield with some air directed to the floor vents. In this mode, the system automatically forces outside air into the vehicle. The air-conditioning compressor does not run unless the outside temperature is at or below freezing. The air-conditioning compressor operates although the indicator light is not on. The air-conditioning indicator light turns off when defrost is selected. If the air-conditioning button is pressed while in defrost mode, the indicator light turns on. If the button is pressed again, the light turns off. Recirculation cannot be selected while in the defrost mode. To help clear the windshield quickly, do the following: 1. Select the defrost mode. 2. Select the highest temperature. 3. Select the highest fan speed. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. < REAR: Press this button to turn the rear window defogger on or off. An indicator light comes on to show that the rear window defogger is activated. Be sure to clear as much snow from the rear window as possible. If driving below 50 mph (80 km/h), the rear window defogger turns off about 15 minutes after the button is pressed. If turned on again, the defogger only runs for about seven minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. If your vehicle's speed is maintained above 50 mph (80 km/h), the rear window defogger remains on once the button is pressed. If your vehicle has heated outside mirrors, the surface of the outside mirrors heat when the rear window defogger is activated. See Outside Power Mirrors on page 135. 180
