Passenger Compartment Air Filter Passenger compartment air, both outside air and recirculated 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 on page 391 for replacement intervals. See your dealer for details on changing the filter. To find out what type of filter to use, see Normal Maintenance Replacement Parts on page 404. To access the passenger compartment air filter you must go through the glove box. 1. Open the glove box and remove all articles from the inside. 2. Tilt the glove box door down by squeezing on each side of the glove box until the door can be lowered from its track. Lower the glove box door. 158
