4-10 Climate control/Operating tips for heater and air conditioner 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 efficiency. & 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 season any problem with the air conditioning system. & Air conditioner compressor shut-off when engine is heavily loaded To improve acceleration and gas mileage, the air conditioner compressor is designed to temporarily shut off during air conditioner operation whenever the accelerator is fully depressed such as during rapid acceleration or when driving up a steep incline. & Refrigerant for your climate control system Check the air conditioner unit for refrigerant leaks, hose conditions, and proper operation each spring. Have the air conditioning system checked by your SUBARU dealer. & Cooling and dehumidifying in high humidity and low temperature 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 1) Air conditioner label Your air conditioner uses ozone friendly refrigerant HFC134a (as shown on the air conditioner label). Therefore, the method 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.
