the “AUTO” button. !
OFF button
The Automatic Climate Control system turns off (the
air conditioner compressor and fan turn off) when the
“OFF” button is pressed.

Passenger’s side
It is possible to make separate temperature settings
for the driver’s side and passenger’s side. Each tem-
perature setting is shown on the display. With the dial
set at your desired temperature, the system automati-
cally adjusts the temperature of air supplied from the
outlets such that the desired temperature is achieved
and maintained.
If the dial is turned fully counterclockwise, the system
gives maximum cooling performance. If the dial is
turned fully clockwise, the system gives maximum
heating performance. !
– Defroster button
To defrost or dehumidify the windshield and front door
windows, push the defroster button “ ”. When the
“ ” button is pushed, regardless whether the air
conditioner is operating or not, outside air is drawn into
the passenger compartment, the air conditioner com-
pressor turns on, air flow is directed towards the wind-
shield and front door windows, and the indicator light
on the button comes on.
After eliminating the fogging from the windshield, re-turn the climate control system to the AUTO mode by
pushing the “AUTO” button or turn off by pushing the
“OFF” button.
Alternatively, push the “ ” button again to return

the system to the setting that was selected before you
activated the defroster. !
Fan speed control button
The fan speed control button has the 7 positions:
AUTO position and 6 different fan speed positions.
The fan speed is shown by the display.
With the fan speed control button in the AUTO posi-
tion, the fan speed changes automatically correspond-
ing the various conditions: air temperature inside and
outside of the passenger’s compartment, intensity of
the sunlight, etc. !
A/C – Air conditioner button
If the windshield starts to fog when the climate control system is operated in the AUTO mode, push the air
conditioner button “A/C” to defog and dehumidify.
When this button is pushed, the air conditioner com-
pressor turns on and the indicator light “A/C” on the
display comes on. After eliminating the fogging from
the windshield, set the system back to the AUTO
mode by pushing the “AUTO” button.
NOTE
The air conditioner compressor does not operate
when the outside air temperature is below 32 °F
(0 °C).

!Air flow mode selection button
Select the desired air flow mode by pushing the air
flow mode selection button. The selected air flow
mode is shown by the display. (Ventilation): Air flows through the instrument panel
outlets.
(Bi-level): Air flows through the instrument panel
outlets and the foot outlets.
(Heat): Air flows through the instrument panel out-
lets, the foot outlets, and some through the windshield
defroster outlets. (Heat-def): Air flows through the instrument panel
outlets, the windshield defroster outlets, and the foot
outlets. ! Air inlet selection button
Select air flow by pushing the air inlet selection button
“/” .
The selected air inlet setting is shown on the control
panel.
(Recirculation): Interior air recirculates inside the
passenger compartment. Use this position when
quickly cooling down the passenger compartment or
to prevent outside air from entering the passenger
compartment. When the recirculation mode is select-

ed, a “ ” indicator light appears on the display.
(Outside air): Outside air is drawn into the pas-
senger compartment. When the climate control sys-
tem is operated in the “AUTO” mode, this position is
selected automatically. (There is one exception: When
the temperature control dial is turned fully counter-
clockwise, the recirculation mode is automatically se-
lected.) When the outside air mode is selected, a
“ ” indicator light appears on the display.
Continued operation in the “ ” position
may fog up the windows. Switch to the
“ ” position 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 “ ” position.
From time to time, return the air inlet selection but-
ton to the “ ” position to draw outside air
into the passenger compartment. !
Temperature sensors
A) Solar sensor
B) Interior air temperature sensor
The automatic climate control system employs several
sensors. These sensors are delicate. If they are treat-
ed incorrectly and become damaged, the system may
not be able to control the interior temperature correct-
ly. To avoid damaging the sensors, observe the follow-
ing precautions:
– 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. Operating tips for heater and air con-

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 ac-
cumulation 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 cool- ing efficiency. ! Lubrication oil circulation in the refrig-
erant circuit
Operate the air conditioner compressor at a low en-
gine speed (at idle or low driving speeds) a few min-
utes each month during the off-season to circulate its
oil. ! Checking air conditioning system be-
fore summer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and proper operation each spring.
Have your SUBARU dealer perform this check. !
Cooling and dehumidifying in high hu-
midity and low temperature weather condition
Under certain weather conditions (high relative humid-
ity, 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 con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accelera-
tion or when driving on a steep upgrade. ! Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method 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 (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 fil-
ter’s dust collection ability. Under extremely dusty con-
ditions, the filter should be replaced more frequently.
Have your filter checked or replaced by your SUBARU
dealer. For replacement, we recommend the use of a
genuine SUBARU air filter kit.
Replacement schedule:
Every 12 months or 7,500 miles (12,000 km) whichev-
er comes first
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 conditioning, heat- ing and defroster performance if not properly
maintained.
