accordance with the air temperature inside and out-
side the passenger compartment, the intensity of sun-
light, and other factors. Pressing the air inlet selection
button cancels the “AUTO” mode. SUBARU recom-
mends using the AUTO position.
Continued operation in the ON position may fog
up the windows. Switch to the OFF position as
soon as the outside dusty condition clears.
„ Air conditioner button The button’s positions and their functions are as fol-
lows:
ON:
The air conditioner operates while the fan is run-
ning.
Push the button to select this position. The indicator
light will illuminate.
OFF: The air conditioner does not operate.
Push the button a second time to select this position.
The indicator light will go off. AUTO: When the button is pressed for at least one
second, the indicator flashes twice. The air conditioner
compressor operation is then adjusted automatically
in accordance with the air temperature inside and out-
side the passenger compartment, the intensity of sun-
light, and other factors. Pressing the button cancels
the “AUTO” mode. SUBARU recommends using the
AUTO position.
NOTE
The air conditioner’s compressor does not oper-
ate with an outside temperature of 32 °F (0 °C) 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 system
may not be able to control the interior temperature cor-
rectly. To avoid damaging the sensors, 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 windshield defroster grille
– Interior air temperature sensor: beside the fan
speed control dial
– Outside temperature sensor: behind front grille.

Operating tips for heater and air con-
ditioner „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 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.
This check is best performed by your SUBARU dealer.

Cooling and dehumidifying in high hu-
midity and low temperature weather
conditions
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 (Turbo model
only)
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. 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) whichev-
er comes first

yDo not place any foreign objects, especially
metal ones such as coins or aluminum foil, into
the accessory power outlet. That could cause a
short circuit. Always put the cap on the acces-
sory power outlet when it is not in use.y Use only electrical appliances which are de-
signed for 12V DC and which consume less
than 120W. Overloading the accessory power
outlet can cause a short circuit. Do not use dou-
ble adapters or more than one electrical appli-
ance.y If the plug on your electric appliance is either
too loose or too tight for the accessory power
outlet, this can result in a poor contact or cause
the plug to get stuck. Only use plugs that fit
properly. y Use of an electric appliance in the accessory
power outlet for a long period of time while the
engine is not running can cause battery dis-
charge.y Before driving your vehicle, make sure that
the plug and the cord on your electrical appli-ance will not interfere with your shifting gears
and operating the accelerator and brake pedals.
If they do, do not use the electrical appliance
while driving.
Cigarette lighter socket
A cigarette lighter socket can be found behind the ash-
tray lid under the climate controls. Push gently on the
lid to open it. A cigarette lighter plug is an optional ac-
cessory. It is available from your SUBARU dealer.
The cigarette lighter socket may also be used as a
power source for an in-car use electrical appliance.
y The electrical power outlet located on the
lower part of the instrument panel is originally
designed to use a genuine SUBARU cigarette

Ashtray
To open the ashtray, push lightly on the lid below the
climate controls.
Fully close the lid after using it to help reduce residual smoke.
To remove the ashtray for cleaning, hold the right and
left sides of the ashtray and pull it out.NOTE
Particles of ash and tobacco will accumulate
around the hinges of the ashtray’s inner lid. Clean
them off using a toothbrush or other narrow-end-
ed implement.
Do not use ashtrays as waste receptacles or
leave a lighted cigarette in an ashtray. This
could cause a fire.
