NOTICE: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you're driving. The access panel for the passenger compartment air filter is located in the back of the glove box. 1. Open the glove box. Passenger Compartment Air Filter Replacement (If Equipped) Passenger compartment air, both outside and recirculated air, is routed through a passenger compartment filter, which is part of a two-piece filter system. The filter removes certain contaminants from the air, including pollen and dust particles, as well as odors such as exhaust or fuel fumes. Reductions in airflow, which may occur more quickly in dusty areas, indicate that the filter needs to be replaced early. For how often to change the air filter, see "Scheduled Maintenance" in the Index. 2. Pull the tab up and out on the outer access panel. 6-17
