Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger will only work when the engine is running. Outlet Adjustment Use the tab located on the air outlets to change the direction of the airflow. = REAR: Press this button to turn the rear window defogger on. Be sure to clear as much snow from the rear window as possible. An indicator light in the button will come on to let you know that the rear window defogger is activated. The rear window defogger will automatically turn off about 15 minutes after the button is pressed. If turned on again, the defogger will only run 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. Your vehicle has heated outside rearview mirrors. The mirrors will heat to help clear fog or frost from the surface of the mirrors when the rear window defog button is pressed. Notice: Don't use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs wouldn't be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. 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 your vehicle. • Use of non-GM approved hood deflectors may adversely affect the performance of the system. • Keep the area around the base of the instrument panel console and air path under the seats clear of objects to help circulate the air inside of your vehicle more effectively. 3-31
