setting, press the“”side of the tempera-
ture control button.
Each temperature setting is shown on the
display. When the “LO ”is shown, the
system provides maximum cooling perfor-
mance. When the “HI ” is shown, the

ter button “
”. When the “”button is
pressed, the air conditioner compressor
automatically operates to quickly defog
the windshield, outside air is drawn into
the passenger compartment, air flow is
directed towards the windshield and front
door windows, and the indicator light on
the button illuminates. After eliminating the fogging from the
windshield, return the climate control
systemtotheFULLAUTOmodeby

! A/C –Air conditioner button
If the windshield starts to fog when the
climate control system is operated in the
AUTO mode, press the air conditionerbutton “A/C ”to defog and dehumidify.
When this button is pressed, the air
conditioner compressor turns on and the
indicator light “A/C ”on the display illumi-
nates. To turn off the air conditioner
compressor, press the “A/C ”button again.
NOTE
The air conditioner compressor does
not operate when the outside air tem-
perature is below 32 8F(0 8C). !
Air flow mode selection buttonSelect the desired air flow mode by
pressing the air flow mode selection
button. The selected air flow mode is
shown on the display.
(Ventilation): Air flows through the
instrument panel outlets.
(Bi-level): Air flows through the instru-
ment panel outlets and the foot outlets.
(Heat): Air flows through the instrument
panel outlets, the foot outlets, and some
through the windshield defroster outlets.
(Heat-def): Air flows through the instru-
ment panel outlets, the windshield defros-
ter outlets, and the foot outlets. NOTE
When the
“
”mode is selected, the air
conditioner compressor automatically
operates to quickly defog the wind-
shield and the air inlet selection is
automatically set to the “outside air ”
mode. ! Air inlet selection button
Select air flow by pressing the air inlet
selection button “”.
ON position (recirculation): Interior air is
recirculated inside the vehicle. Press the
air inlet selection button to the ON position
for fast cooling with the air conditioner or
when driving on a dusty road. The
indicator light will illuminate.
OFF position (outside Air): Outside air is
drawn into the passenger compartment.

Press the air inlet selection button to the
OFF position when the interior has cooled
to a comfortable temperature and the road
is no longer dusty. The indicator light will
turn off.
WARNING
Continued operation in the ON posi-
tion (recirculation) may fog up the
windows. Switch to the OFF position
(outside air) as soon as the outside
dusty condition clears.
NOTE
When driving on a dusty road or behind
a vehicle that emits unpleasant exhaust
gases, set the air inlet selection button
to the ON position (recirculation).
From time to time, return the air inlet
selection button to the OFF position
(outside air) to draw outside air into the
passenger compartment. &
Temperature sensors
1) Solar sensor
2) Interior air temperature sensor
The automatic climate control system
employs several sensors. These sensors
are delicate. If they are treated incorrectly and become damaged, the system may
not be able to control the interior tempera-
ture correctly. To avoid damaging the
sensors, observe the following precau-tions: –
Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows:– Solar sensor: beside windshield
defroster grille– Interior air temperature sensor: on the
side of the driver-side part of the center panel – Outside temperature sensor: behind
front grille. Climate control

Operating tips for heater and
air conditioner &Cleaning ventilator grille
Always 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 accumulation of insects and leaves
on the condenser. &Efficient cooling after parking
in direct sunlight
After 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 circuit
Operate 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 sea-son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer. & Cooling and dehumidifying in
high humidity and low tem-
perature weather condition
Under certain weather conditions (high
relative humidity, low 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 when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steepupgrade. & Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od of adding, changing 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
Your vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule shown in the
following table. This schedule should be
followed to maintain 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.
Replacement schedule: Every 15 months or 15,000 miles (24,000
km) whichever comes first
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter. . Reduction of the air flow through
the vents.
. Windshield gets easily fogged or
misted. NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained. &
Replacing an air filter
1. Remove the glove box. (1) Open the glove box.
(2) Remove the damper shaft from the
glove box.
(3) Pull out the glove box.
2. Remove the cover of the air filter. Climate control
