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 filter traps most of the pollen from the air entering the air conditioning module. Like your engine's air cleaner filter, it may need to be changed periodically. For information on how often to change the passenger compartment air filter, see "Maintenance Schedule" in the Index. To change the passenger compartment air filter, use the following steps: 1. Turn off the ignition when the windshield wipers are in the up position. 2. Raise the hood. 3. Disconnect the windshield washer pump hose from the fender rail and air inlet grille. 4. Remove the hood weatherstrip from the passenger's side of the vehicle (peel back halfway to center). 5. Remove the three air inlet grille retainers. 6. Remove the air inlet grille. Passenger Compartment Air Filter The passenger compartment air filter is located underneath your hood below the windshield wiper arm, on the passenger's side (below the air inlet grille) of the vehicle. 6-17
