Your vehicle's air conditioning system is equipped with an air filtration system.
Replace the air filter element according to the replacement schedule found in the "Warranty and Maintenance Booklet". This schedule should be followed to maintain the filter's dust collection ability. Under extremely dusty conditions, the filter should be replaced more frequently. Have your filter checked or replaced by your SUBARU dealer. For replacement, use only a genuine SUBARU air filter kit.
CAUTION
Contact your SUBARU dealer if the following occurs, even if it is not yet time to change the filter:
NOTE
The filter can influence the air conditioning, heating and defroster performance if not properly maintained.
