Both outside and recirculated air are routed through a passenger compartment air filter. Pollen, dust particles and other contaminants are removed by the filter. Airflow reductions indicate that the filter needs to be replaced. For a replacement filter see your dealer/retailer. See Scheduled Maintenance for replacement intervals.

The access panel for the air filter is behind the glove box. To replace the filter:

  1. Open the glove box door. Push each side of the glovebox in and pull out to remove.

  2. Object Number: 2034320  Size: G1
  3. Push the side fastener to release and remove the filter cover.

  4. Object Number: 1967245  Size: G9
  5. Remove the air filter.
  6. Install a new air filter and reassemble the unit by reversing the steps.

Replacing the air filter is recommended, but will not damage the vehicle if it is not.
