When to Replace the Dust and Pollen Filter  
Using an air freshener may reduce the deodorizing  
effect of the dust and pollen filter, and may reduce its  
life.

maintenance schedule. It is recommended to replace the filter even sooner if the  
vehicle has been driven in a dusty environment.  
If the airflow from the climate control system  
deteriorates noticeably, and the windows fog up
