For 1990-2009 cars

Outside air is routed through a passenger compartment air filter before entering the vehicle. This filter removes certain particles from the air, including pollen and dust particles. Reductions in airflow, which may occur more quickly in dusty areas, indicate that the filter needs to be replaced early.

The filter should be replaced as part of routine scheduled maintenance. See Scheduled Maintenance for when to replace the filter.

To change the passenger compartment air filter, use the following steps:

1. The passenger's side air inlet panel is located below the center of the passenger's side wiper blade. Remove the push pin retaining the air inlet panel. Pry the center of the push pin out 0.5 in (13 mm) for removal.
2. Open the hood.
3. Remove the three push pins from the top and forward edge of the passenger's side air inlet panel.
4. Remove the air inlet panel to access the filter.
5. Press the release tab on the driver's side of the filter and pull out the edge of the filter.
6. Remove the filter from the vehicle.
7. Install a new passenger compartment air filter. For the type of filter to use see Maintenance Replacement Parts .
8. Reverse Steps 1 through 5.
