= (Rear Window Defogger): Press this button to turn the rear window defogger on and off. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off approximately 20 minutes after the button is pressed. If turned on again, the defogger will only run for approximately 20 minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all the windows are clear. 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 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 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. • If the airflow seems low when the fan is at the highest setting, the passenger compartment air filter may need to be replaced. See "Passenger Compartment Air Filter" following, for more information. Passenger Compartment Air Filter The passenger compartment air filter is located near the passenger's side windshield wiper arm, underneath the inlet grille. The filter traps most of the pollen from entering the climate control system. Similar to the engine's air filter, it may need to be changed periodically to insure system performance. See Scheduled Maintenance on page 6-4 for more information. Outlet Adjustment Rotate and turn the air outlets, located in the middle and at each outboard side of the instrument panel, to adjust the direction of the airflow. 3-33
