When the indicator light on the air inlet
selection button illuminates, interior air is
recirculated inside the vehicle. Press the
air inlet selection button to the ON position
in the following cases.
- When driving on a dusty road
- When you want cooling perfor-
mance to increase (for example, in
particularly hot weather)
 Outside air circulation:
When the indicator light on the air inlet
selection button does not illuminate,
outside air is drawn into the passenger
compartment. Press the air inlet selection button to the OFF position in the following

cases.
- When the road is no longer dusty
- When the interior has cooled to a

NOTEWhen outside air circulation is
selected, the system may automati-
cally adjust the air inlet setting

Operating Tips for Heater and Air Conditioner
204system to the setting that had been
selected before the defroster was acti-
vated.
4-6. Operating Tips for Heater and Air Conditioner■ Cleaning Ventilator Grille1) Front ventilator inlet grille
2) CondenserAlways keep the front ventilator inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept
clean because cooling performance is
impaired by any accu mulation of insects
and leaves on the condenser.
■ Efficient Cooling after
Parking in Direct SunlightAfter 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 CircuitOperate 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
SeasonCheck the air conditioner unit for refrig-
erant leaks, hose conditions, and proper
operation each spring. Have the air condi-
tioning system checked by your SUBARU
dealer.

■Cooling and Dehumidifying
in High Humidity and Low
Te mperature Weather Condi -
tionUnder certain weather conditions (high
relative humidity, lo w 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 Whe n Engine Is
Heavily LoadedTo improve acceleration and gas mileage,
the air conditio ner compressor is
designed to temporarily shut off during air
conditioner operation whenever the accel-
erator is fully depressed such as during
rapid acceleration or when driving on a
steep upgrade.
■ Refrigerant for Your Climate
Control Syste m1) Air conditioner labelYour air conditioner uses ozone friendly
refrigerant R-1234yf (HFO-1234yf).
Before adding, changing or checking the
refrigerant, check the air conditioner label
in the location shown in the illustration to
confirm the type of refrigerant is used in
your vehicle.
Consult your SUBARU dealer for service.
Repairs needed as a result of using the
wrong refrigerant are not covered under
warranty.
4-7. Air Filtration SystemYour vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the cabin air filter according to
the replacement schedule found in the
“Warranty and Maintenance Booklet”.
This schedule should be followed to main-
tain the filter’s dust collection ability.
Under extremely dusty conditions, the
filter should be replaced more frequently.
Have your filter checked or replaced by
your SUBARU dealer. For replacement,
use only a genuine SUBARU air filter kit.NOTEThe filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
