0 (Defrost): Pressing this button directs most of the air to the windshield and the side window outlets, with some air directed to the floor outlets. In this mode, the system will automatically turn off recirculation and run the air-conditioning compressor, unless the outside temperature is at or below freezing. Recirculation cannot be selected while in the defrost mode. Do not drive the vehicle until all the windows are clear. 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. Outlet Adjustment Use the louvers located on the air outlets to change the direction of the airflow. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. Operation Tips • Clear away any ice, snow, or leaves from the air inlets at the base of the vehicle that may block the flow of air into your vehicle. < REAR: Press this button to turn the rear window defogger on or off. 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 turn off about 10 minutes after the button is pressed. If turned on again, the defogger will only run for about five minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. • 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 your vehicle more effectively. 3-28
