The vehicle has a passenger compartment particulate air filter. It is located in the engine compartment, below the air inlet grille on the passenger side.

The filter traps most of the pollen from air entering the climate control system. It needs to be changed periodically to ensure system performance. For information on how often to change the passenger compartment air filter, see Scheduled Maintenance.

To change the passenger compartment air filter:

  1. Turn off the ignition when the windshield wipers are in the up position.
  2. Raise the vehicle hood.
  3. Pull back the hood weatherstrip from the passengers side of the vehicle halfway to center.

  7. Remove the air inlet grille.
  8. Remove the water deflector plate.
  9. Remove the old passenger compartment air filter.
  10. Reverse the steps to install the new air filter.

For best climate control system performance, reinstall the air filter.
