The passenger compartment air filter traps most of the pollen from the air entering you vehicle. Like your vehicle's engine air filter, it will need to be changed periodically.

A substantial reduction in air flow indicates that the filter needs to be replaced. See Maintenance section in this handbook to find out how to replace the passenger compartment air filter. To find out what type of filter use, see "Replacement Parts."

  1. Open the hood of your vehicle. The access panel for the passenger compartment air filter is located on the passenger side of the cowl grill, at the base of the windshield.
  2. Gently remove hood-to-cowl seal by peeling it up from one end.
