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

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,

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-
