Operating tips for heater and air
conditioner
J Cleaning ventilation grille
Always keep the front ventilation inlet grille free of
snow, leaves, or other obstructions to ensure effi-
cient heating and defrosting. Since the condenser is
located in front of the radiator, this area should be
kept clean because cooling performance is im-
paired by any accumulation of insects and leaves
on the condenser.
J Efficient cooling after parking in
direct sunlight
After parking in direct sunlight, drive with the win-
dows 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 win-
dows closed during the operation of the air condi-
tioner for maximum cooling efficiency.
J Lubrication oil circulation in the
refrigerant circuit
Operate the air conditioner compressor at a low en-
gine speed (at idle or low driving speeds) a few
minutes each month during the off-season to circu-
late its oil.
J 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.
