You may notice a slight change in engine performance when the air-conditioning compressor shuts off and turns on again. This is normal. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. @ (Recirculation): Press to turn the recirculation mode on or off. An indicator light comes on to show that recirculation is on. This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to help prevent outside air and odors from entering the vehicle. Recirculation mode can be used with vent and bi-level modes, but it cannot be used with floor, defog or defrost modes. If recirculation mode is selected with floor, defog, or defrost modes, the indicator flashes three times and turns off to indicate the selection is not available. The air conditioning compressor may also run while in recirculation mode. This is normal and helps to prevent window fogging. If the weather is cold and damp, the system may cause the windows to fog while using recirculation mode. If the windows do start to fog, select defog or defrost mode and increase fan speed. Recirculation mode, if selected, will be cleared when the engine is turned off. < (Rear): Press to turn the rear window defogger on or off. An indicator light comes on to show that the rear window defogger is on. The rear window defogger will turn off approximately 10 minutes after the button is pressed. If additional warming time is needed, press the button again. The heated mirrors will also come on when the rear window defogger is turned on. See Outside Heated Mirrors on page 2-34. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. 3-22
