The rear window defogger and heated mirrors are automatically disabled when the retractable hardtop is moving or down. 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. Passenger Compartment Air Filter The passenger compartment air filter removes certain particles from the air, including pollen and dust particles. Reductions in airflow, which may occur more often in dusty areas, indicate that the filter may need to be replaced early. The filter should be replaced as part of the routine scheduled maintenance. See Scheduled Maintenance on page 7-4 for more information. To check or replace the air filter, do the following: 1. With the hood open, unlatch and remove the access panel. The passenger compartment air filter and access panel are located on the passenger's side of the engine compartment near the battery. See Engine Compartment Overview on page 6-12 for more information on location. 2. Pull the old filter out of the housing. 3. Insert the new filter into the housing. 4. Reinstall the air filter access panel. Outlet Adjustment Use the thumbwheel to open or close the outlets. 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. 3-42
