Automatic climate control
system (if equipped)
Although this climate control system can
be used as a full-automatic climate control
system, it can also, if desired, be used as
a semi-automatic climate control system.
When it is used as a full-automatic climate
control system, the outlet air temperature,
fan speed, air flow distribution, air inlet
control, and air conditioner compressor
operation are all automatically controlled
to maintain a constant, comfortable tem-
perature inside the vehicle.
NOTE yOperate the automatic climate con-
trol system when the engine is run-
ning. y When the engine coolant is cold, the
blower does not run. y In the “AUTO” mode, when the air
temperature in the passenger compart-
ment is sufficiently cool, the air condi-
tioner compressor does not operate.
For efficient defogging or dehumidify-
ing in cold weather, press the “A/C”
button to operate the air conditioner
compressor. y Even when cooling is not necessary,
setting the temperature much lower
than the current outlet air temperature turns on the air conditioner compres-
sor automatically and the “A/C” indica-
tor light on the control panel comes on.

Fan speed control dial
The fan operates only with the ignition
switch in the ON position. The fan speed
control dial is used to select the AUTO
(automatic control) mode or to select the
desired fan speed. The dial’s positions
and their functions are as follows:
OFF: The fan does not operate.
AUTO: The fan speed is adjusted auto-
matically in accordance with the air tem-
perature inside and outside the passenger
compartment, the intensity of sunlight,
and other factors. SUBARU recommends
using the AUTO position.
Other positions: The fan speed can be
adjusted in seven steps.
NOTE
With the fan speed control dial in the AUTO position and the air flow control
dial in the “ ”, “ ”, or “ ” po-
sition, the fan does not operate during
engine warm-up until the engine cool-
ant temperature exceeds approx. 122
qF
(50 qC).
„ Temperature control dial
This dial is used to set the desired interior
temperature. With the dial set to your de-
sired temperature, the system automati-
cally adjusts the temperature of air sup-
plied from the outlets such that the desired
temperature is achieved and maintained.
If the dial is turned fully counterclockwise,
the system gives maximum cooling perfor-
mance. If the dial is turned fully clockwise,
the system gives maximum heating per- formance. „
Air flow control dial
This dial has the following six positions.
The outlets from which air is supplied in
each position are as follows: AUTO: The air flow control is adjusted au-
tomatically in accordance with the air tem-
perature inside and outside the passenger
compartment, the intensity of sunlight,
and other factors. SUBARU recommends
using the AUTO position.

NOTE
The air conditioner’s compressor does
not operate with an outside tempera-
ture of 32 qF (0 qC) or lower.
„ Temperature sensors
1) Interior air temperature sensor
2) Solar sensor
The automatic climate control system em-
ploys several sensors. These sensors are
delicate. If they are not treated properly
and become damaged, the system may
not be able to control the interior tempera-
ture correctly. To avoid damaging the sen- sors, observe the following 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 the windshield de-
froster grille.
– Interior air temperature sensor: near the
ignition switch.
– Outside temperature sensor: behind the
front grille.
Operating tips for heater and
air conditioner „
Cleaning ventilation grille
Always keep the front ventilation inlet
grille free of snow, leaves, or other ob-
structions 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 al-

low 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 con-
ditioner 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 op-
eration each spring. Have your SUBARU
dealer perform this check. „ Cooling and dehumidifying in
high humidity and low tem-
perature weather conditions
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 sys-
tem.
„ Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is de-
signed 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 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, re-
place the filter element according to the
replacement schedule shown in the fol-
lowing. This schedule should be followed
to maintain the filter’s dust collection abili-
ty. Under extremely dusty conditions, the
filter should be replaced more frequently.
It is recommended that you have your fil-
ter checked or replaced by your SUBARU
dealer. For replacement, use only a genu-
ine SUBARU air filter kit.
Replacement schedule:
Every 12 months or 7,500 miles (12,000
km) whichever 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 throughthe vents.
– Windshield gets easily fogged or misted.
