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 early.

The filter should be replaced as part of routine scheduled maintenance. See Scheduled Maintenance for replacement intervals. See your retailer for details on changing the filter. To find out what type of filter to use, see Maintenance Replacement Parts .
