closed during the operation of the air conditioner for maximum cool-
ing efficiency.
B
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-sea-
son to circulate its oil.
B
Checking air conditioning system before summer season
Check the air conditioner unit for refrigerant leaks, hose conditions,
and proper operation each spring. This check is best performed by
your SUBARU dealer.
B
Cooling and dehumidifying in high humidity and low tempera-
ture weather condition
Under certain weather conditions (high relative humidity, low tempera-
tures, 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.
B
Air conditioner compressor shut-off when engine is heavily
loaded
To improve acceleration and gas mileage, the air conditioner com-
pressor is designed to temporarily shut off during air conditioner op-
eration whenever the accelerator is fully depressed such as during
rapid accerelation or when driving on a steep upgrade.
B
Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant HFC134a. There-
fore, 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.
