Subaru Legacy BN/BS (2015-2019) Owners Manual: Air filtration system (if equipped).

Your vehicle's air conditioning system is equipped with an air filtration system.

Replace the air filter element according to the replacement schedule shown in the following table. 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. For the replacement schedule, refer to the "Warranty and Maintenance Booklet".

NOTE The filter can influence the air conditioning, heating and defroster performance if not properly maintained.
