Rear Window Defogger The lines you see on the rear window warm the glass. With your vehicle's engine running, press this button to turn on the rear defogger. Ventilation System The ventilation system supplies outside air into the vehicle when it is moving. Outside air will also enter the vehicle when the heater or the air conditioning fan is running. The rear window defogger heats the rear window and both outside rearview mirrors. The system will automatically shut off after about 15 minutes. If further defogging is desired, press the button again. Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window. NOTICE: Do not try to clear frost or other material from the inside of the rear window with a razor blade or anything else that is sharp. This may damage the rear defogger grid. The repairs wouldn't be covered by your warranty. The front outlets are located in the center and at each side of the instrument panel. You can adjust the direction of airflow by moving the center control levers or you can stop the airflow by moving the dial located on each side of the outlets to the "O" position. 3-7
