Operating Tips for Heater and Air Conditioner 273
& Efficient Cooling after Parking in Direct Sunlight s04ad02
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 efficiency.
& Lubrication Oil Circulation in the Refrigerant Circuit s04ad03
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 s04ad04
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 Condition
s04ad05
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.
& Air Conditioner Compressor Shut-Off When Engine Is Heavily Loaded s04ad06
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 on a steep upgrade.
& Refrigerant for Your Climate Control System s04ad07
