of insec ts and leaves on the c ond enser. Efficient cooling after parking in direct sunlight
After p arking in d irec t sunlig ht, d rive with the wi nd ows op en for a few
minutes to allow outsid e air to c irc ulate into the heated interior. This re-
sults in q uic ker c ooling b y the air c ond itioner. Ke ep the wind ows

effic ienc y. Lubrication oil circulation in the refrigerant circuit
Op erate the air c ond itioner c omp ressor at a low eng ine sp eed (at id le
or low d riving sp eed s) a few minutes eac h month d ur ing the off-sea-
son to c irc ulate its oil. Checking air conditioning system before summer season
Chec k the air c ond itioner unit for refrig erant leak s, hose c ond itions,
and p rop er op eration eac h sp ring . This c hec k is b es t p erformed b y
your SUBARU d ealer. Cooling and dehumidifying in high humidity and low tempera- ture weather condition
Und er c ertain weather c ond itions (hig h relative hum id ity, low temp era-
tures, etc .) a small amount of water vap or emission from the air outlets
may b e notic ed d uring c ooling or d ehumid ifying . Thi s c ond ition is nor-

tem. Air conditioner compressor shut-off when engine is heavily loaded
To imp rove ac c eleration and g as mileag e, the air c o nd itioner c om-

Refrigerant for your climate control system
Your air c ond itioner uses ozone friend ly refrig eran t HFC134a. There-
fore, the method of ad d ing , c hang ing or c hec king th e refrig erant is
d ifferent from the method for CFC12 (freon). Consul t your SUBARU
