Climate control/Air filtration system allow outside air to circulate into the heated interior. This results in quicker cooling by the air conditioner. Keep the windows closed during the operation of the air conditioner for maximum cooling effi- ciency. & Lubrication oil circulation in the refrigerant circuit Operate the air conditioner compressor at a low engine speed (at idle or low driving speeds) a few minutes each month during the off-season to circulate its oil. & Checking air conditioning system before summer sea- son Check the air conditioner unit for refriger- ant leaks, hose conditions, and proper operation each spring. Have the air con- ditioning system checked by your SUBARU dealer. & Cooling and dehumidifying in high humidity and low tem- perature weather conditions Under certain weather conditions (high relative humidity, low temperatures, etc.) a small amount of water vapor emission from the air outlets may be noticed. This condition is normal and does not indicate 4-11 any problem with the air conditioning system. Air filtration system & Air conditioner compressor shut-off when engine is heavily loaded Your vehicle’s air conditioning system is equipped with an air filtration system. Replace the cabin air filter 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. To improve acceleration and gas mileage, the air conditioner compressor is designed to temporarily shut off during air condi- tioner operation whenever the accelerator is fully depressed such as during rapid acceleration or when driving on a steep upgrade. & Refrigerant for your climate control system Your air conditioner uses ozone friendly refrigerant HFC134a. Therefore, the meth- od of adding, changing or checking the refrigerant is different from the method for CFC12 (freon). Consult your SUBARU dealer for service. Repairs needed as a result of using the wrong refrigerant are not covered under warranty. CAUTION Contact your SUBARU dealer if the following occurs, even if it is not yet time to change the filter: . Reduction of the airflow through the vents. . Windshield gets easily fogged or misted. NOTE The filter can influence the air condi- tioning, heating and defroster perfor- mance if not properly maintained. – CONTINUED –
