If your vehicle is equipped with an air conditioner, when the “
” position is selected, the air condi-
tioner automatically operates regardless of the posi-
tion of the air conditioner button. NOTE
Warm air also comes out from the right and left
air outlets. To stop warm air flow from these out- lets, turn the corresponding knob clockwise.
Heating and defrosting

To direct warm air toward the floor and the wind- shield:
1. Set the air inlet selection lever to the “
”
position.
2. Set the air flow control dial to the “
” position.
3. Set the temperature control dial to the most com-
fortable level.

Bi-level heating
HG4026AA
This setting allows you to direct air of different tem-
peratures from the instrument panel and foot outlets.
The air from the foot outlets is slightly warmer than
from the instrument panel outlets.
1. Set the air inlet selection lever to the “
”
position.
2. Set the air flow control dial to the “
” position.
3. Set the temperature control dial to the desired
temperature level.
4. Set the fan speed control dial to the desiredspeed.
Setting the temperature control dial fully turned to
the red area or blue area decreases the temperature
difference between the air from the instrument panel
outlets and the air from the foot outlets.

Operating tips for heater and air conditioner Cleaning ventilator grille
HG4016BA
Always keep the front ventilator 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.
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. 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. 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.

Cooling and dehumidifying in high humidity and low temperatureweather condition
Under certain weather conditions (high relative hu-
midity, low temperatures, etc.) a small amount of wa-
ter vapor emission from the air outlets may be not-
iced. This condition is normal and does not indicate
any problem with the air conditioning system. Air conditioner compressor shut-off when engine is heavily loaded
To improve acceleration and gas mileage, the air
conditioner compressor is designed to temporarily
shut off during air conditioner operation whenever
the accelerator is fully depressed such as duringrapid acceleration or when driving on a steepupgrade. Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method of adding, chang-
ing 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.

Air filtration system (if equipped) If your vehicle’s air conditioning system is equipped
with an air filtration system, replace the filter element
according to the replacement schedule shown
below. This schedule should be followed to maintain the filter ’s dust collection ability. Under extremely
dusty conditions, the filter should be replaced more
frequently. Since the filter element is a viscous type,
it is unnecessary to clean or wash the element.
Have your filter checked or replaced by your
SUBARU dealer.
Replacement schedule: Every 12 months or 7,500 miles (12,000 km) whichever comes first
NOTE The filter can influence the air conditioning, heat- ing and defroster performance.
