The passenger compartment air is routed through a passenger compartment filter. The 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.
The filter should be replaced as part of routine scheduled maintenance. See Scheduled Maintenance for replacement intervals. To find out what type of filter to use, see Maintenance Replacement Parts .
The passenger compartment air filter can be accessed from under the hood.
Remove the push pins from the air filter access panel.
When installing a new air filter make sure the AIR FLOW arrow is pointing rearward.
