Operating tips for heater and air conditioner
1) Front ventilation inlet grille
Always keep the front ventilation inlet grille free of snow, leaves, or other obstructions to ensure efficient heating and defrosting. Since the condenser is located in front of the radiator, this area should be kept clean because cooling performance is impaired by any accumulation of insects and leaves on the condenser.
After parking in direct sunlight, drive with the windows open for a few minutes to 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.
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.
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.
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 any problem with the air conditioning system.
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.
Your air conditioner uses ozone friendly refrigerant HFO-1234yf (R-1234yf). Therefore, the method of adding, changing or checking the refrigerant is different from the method for Freon, CFC12 (R12) or HFC134a (R134a). Consult your SUBARU dealer for service. Repairs needed as a result of using the wrong refrigerant are not covered under warranty.
