Outlet Adjustment Use the thumbwheel to open or close the outlets. Passenger Compartment Air Filter The passenger compartment air filter removes certain odor and 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 6-4 for more information. The passenger compartment air filter is located on the passenger's side of the engine compartment near the battery. See Engine Compartment Overview on page 5-12 for more information on location. To check or replace the air filter, do the following: 1. With the hood open, unlatch and remove the access panel. 2. Pull the old filter out of the housing. 3. Insert the new filter into the housing. The filter should be fully inserted with the arrows pointing up. 4. Reinstall the air filter access panel. 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. 3-40
