= (Rear Window Defogger): Press this button to turn the rear window defogger on or off. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off about 10 minutes after the button is pressed, but if the vehicle's speed is above 30 mph (48 km/h), the rear defogger will stay on continuously. 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. The heated outside rearview mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defogger button is on. Notice: Do not try to clear frost or other material from the inside of the front windshield and rear window with a razor blade or anything else that is sharp. This may damage the rear window defogger grid and affect your radio's ability to pick up stations clearly. The repairs wouldn't be covered by your warranty. j (Side Window Defog): Turn the thumbwheel to this symbol to use the side window defog setting. The air coming through the outlets will be directed toward the side windows to clear fog. k (Open): Turn the thumbwheel to this symbol to open the outlets completely and allow the maximum amount of air to enter your vehicle. A small amount of air will still be directed to the side windows. l (Closed): Turn the thumbwheel to this symbol to close the outlets and minimize the amount of air entering the vehicle. 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 path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. Outlet Adjustment Use the knobs located in the center of each outlet to change the direction of the airflow. Use the thumbwheels to open or close the outlets. • If the airflow seems low when the fan speed is at the highest setting, the passenger compartment air filter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-29. 3-28
