Passenger Compartment Air Filter The passenger compartment air filter traps most of the pollen from the air entering your vehicle. Like your vehicle's air cleaner filter, it may need to be changed periodically. For how often to change the passenger compartment air filter, see "Maintenance Schedule" in the Index. 1. To access the passenger compartment air filter, use a tool to gently pry the cover up. (If your vehicle has tabs that allow you to unlatch the cover with your fingers, you will not need a tool for this step.) The access panel for the passenger compartment air filter is located under the hood near the windshield, on the passenger's side of the vehicle. 6-19
