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 .Operate the automatic climate con-
trol system when the engine is running. . When the engine coolant is cold, the
blower does not run.. 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.. 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 ”indi-
cator light on the control panel comeson. & Control panel

partment, the intensity of sunlight, and

other factors. Pressing the button cancels the“AUTO ”mode. SUBARU recommends
using the AUTO position.
NOTE
The air conditioner ’s compressor does
not operate with an outside tempera-
ture of 32 8F(0 8C) or lower.
& Temperature sensors
1) Interior air temperature sensor
2) Solar sensor
The automatic climate control system
employs several sensors. These sensors
are delicate. If they are not treated
properly and become damaged, the sys-
tem may not be able to control the interior
temperature correctly. To avoid damaging
the sensors, observe the following pre- cautions: –
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 defros-
ter grille– Interior air temperature sensor: beside
the fan speed control dial– Outside temperature sensor: behind
front grille. Operating tips for heater and
air conditioner &
Cleaning ventilation 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 Climate control

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 of 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 conditioningsystem. &
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
If your vehicle
’s air conditioning system is
equipped with an air filtration system,
replace the filter element according to
the replacement schedule shown in the
following. This schedule should be fol-
lowed to maintain the filter ’s dust collec-
tion ability. Under extremely dusty condi-
tions, the filter should be replaced more
frequently. It is recommended that you
have your filter checked or replaced by
your SUBARU dealer. For replacement,
use only a genuine SUBARU air filter kit.
Replacement schedule: Every 12 months or 7,500 miles (12,000
km) whichever comes first
