automatically set to “outside air ”
mode. &
Air inlet selection buttonON position (recirculation): Interior air is
recirculated inside the vehicle. Push 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.
Push 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. AUTO: Turn the fan speed control dial and
airflow control dial to the AUTO position.
The air inlet control is then adjusted
automatically in accordance with the air
temperature inside and outside the pas- senger compartment, the intensity of sun-
light, and other factors. Pressing the air
inlet selection button cancels the
“AUTO ”
mode. To return to “AUTO ”mode, turn the
fan speed control dial or airflow control
dial to a position other than the AUTO
position. Then turn to “AUTO ”mode.
SUBARU recommends using the AUTOposition.
WARNING
Continued operation in the ON posi-
tion may fog up the windows. Switch
to the OFF position as soon as the
outside dusty condition clears.

&Air conditioner button
The button positions and their functions
are as follows. ON: The air conditioner operates while the
fan is running.
Push the button to select this position. The
indicator light will illuminate. OFF: The air conditioner does not oper-
ate.
Push the button again to select this
position. The indicator light will turn off. AUTO: Turn the fan speed control dial and
airflow control dial to the AUTO position.
The air conditioner compressor operation
is then adjusted automatically in accor-
dance with the air temperature inside and
outside the passenger compartment, the
intensity of sunlight, and other factors. Pressing the button cancels the
“AUTO ”
mode. To return to “AUTO ”mode, turn the
fan speed control dial or airflow control
dial to a position other than the AUTO
position. Then turn to “AUTO ”mode.
SUBARU recommends using the AUTOposition.
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 Climate control

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 the windshield
defroster 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 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 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

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
Replace the filter element according to the
replacement schedule as follows. This
schedule should be followed to maintain
the filter
’s dust collection ability. Under
extremely dusty conditions, 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
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter: . Reduction of the airflow 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. Climate control

Antenna system &Roof antenna
CAUTION
. Be sure to lower the antenna rod
before entering garages, parking
towers and other locations with
low ceilings.
. Remove the antenna rod before
washing your car at a car wash. If
the antenna rod is left attached, it
may scratch the roof.
. When reinstalling the removed
antenna rod, be sure to fully
tighten it.
1) Unscrew
2) Remove
The roof antenna is installed in the center
at the rear part of the roof.
It is possible to remove the antenna rod by
unscrewing it from its base. &
FM reception
Although FM is normally static free,
reception can be affected by the surround-
ing area, atmospheric conditions, station
strength and transmitter distance. Build-
ings or other obstructions may cause
momentary static, flutter or station inter-
ference. If reception continues to be
unsatisfactory, switch to a stronger station. Audio
