Outlet Adjustment Use the thumbwheels located next to and below the air outlets to change the direction of the airflow and to open and 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 path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. The filter should be replaced as part of routine scheduled maintenance. See Scheduled Maintenance on page 6-4 for replacement intervals. See your dealer/retailer for details on changing the filter. To find out what type of filter to use, see Maintenance Replacement Parts on page 6-14. To access the passenger compartment air filter you must go through the glove box. 1. Open the glove box and remove all articles from the inside. Passenger Compartment Air Filter Passenger compartment air, both outside air and recirculated air, is routed through a passenger compartment filter. The filter removes certain particles from the air, including pollen and dust particles. Reductions in airflow, which may occur more quickly in dusty areas, indicate that the filter needs to be replaced early. 2. Tilt the glove box door down by squeezing on each side of the glove box until the door can be lowered from its track. Lower the glove box door. 3-21
