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. Press to turn the rear window defogger on or off. Be sure to clear as much snow from the rear window as possible. An indicator light comes on to show that the rear window defogger is on. 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. If the vehicle is moving faster than 50 mph (80 kph), the rear defogger will stay on. The defogger can also be turned off by turning off the engine. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by the vehicle warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. Outlet Adjustment Use the thumbwheels located next to and below the air outlets to change the direction of the airflow and to open and close the outlets. < (Rear): Operation Tips • Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the flow of air into the vehicle. • Use of non-GM approved hood deflectors may adversely affect the performance of the system. • Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. 3-21
