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

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 come on.
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
go off. AUTO: When the air inlet selection button
is pressed for at least one second, the
indicator flashes twice. The air inlet control
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 air inlet selection button
cancels the “AUTO ”mode. SUBARU
recommends using the AUTO position.
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 ’s 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 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 outside the passenger com-
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

smell. SUBARU recommends that you try
a different brand of unleaded gasoline
having lower sulfur to determine if the
problem is fuel related before returning
your vehicle to an authorized dealer forservice. !MMT
Some gasoline contains an octane-en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/Mal-
function indicator lamp may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not
be covered by your warranty. ! Gasoline for cleaner air
Your use of gasoline with detergent
additives will help prevent deposits from
forming in your engine and fuel system.
This helps keep your engine in tune and
your emission control system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never
need to add any fuel system cleaning
agents to your fuel tank. Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as MTBE
(Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in
your vehicle, but should contain no more
than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station
operators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-sions.
As additional guidance, only use fuels
suited for your vehicle as explained in thefollowing. .
Fuel should be unleaded and have an
octane rating no lower than that specified
in this manual. . Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLY if it does not exceed 5% of the fuel
mixture ANDif it is accompanied by sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanol
EXCEPT
under these conditions. . If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer. . Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
CAUTION
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty. Starting and operating

the tank whenever the low fuel warning
light comes on. Engine misfires as a
result of an empty tank could cause
damage to the engine.
CAUTION
. Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
. Make sure that the cap is tigh-
tened until it clicks to prevent
fuel spillage in the event of anaccident.
. Do not let fuel spill on the exterior
surfaces of the vehicle.
Fuels may cause paint damage,
which is not covered under the
SUBARU Limited Warranty.
. Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting, and your fuel
tank and emission control sys-
tem might be damaged. State emission testing (U.S. only)
At state inspection time, remember to
tell your inspection or service station in
advance not to place your Subaru AWD
vehicle on a two-wheel dynamometer.
Otherwise, serious transmission da-
mage will result.
Some states have started using dynam-
ometers in their state inspection programs
in order to meet their obligation under
federal law to implement stricter vehicle
emission standards to reduce air pollution
from vehicles. A dynamometer is a tread-
mill or roller-like testing device that allows
your vehicle
’s wheels to turn while the
vehicle remains in one place. Depending
on the severity of a state ’s air pollution
problems, the states must adopt either a“ basic ”or “enhanced ”vehicle emission
inspection test. Normally, a portion of the
basic emission test consists of an emis-
sion inspector inserting an analyzer probe
into the exhaust pipe of an idling vehicle
for a short period of time. States with more
severe air pollution problems are required
to adopt an enhanced vehicle emission
test. This test simulates actual driving
conditions on a dynamometer and permits
more accurate measurement of tailpipe
emitted pollution than the basic emission test.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
programs have
EXEMPTEDSubaru AWD
vehicles from the portion of the testing
program that involves a two-wheel dy-
namometer.
There are some states that use four-wheel
dynamometers in their testing programs.
When properly used, that equipment will
not damage an AWD Subaru vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
WARNING
Testing of an All-Wheel Drive vehicle
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby. Starting and operating

vehicles.
. When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS
system than one without. When
driving under these conditions,
therefore, reduce your speed and
leave ample distance from othervehicles.
. When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the
operation of the ABS system.
& ABS system self-check
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is
caused by an automatic functional test of
the ABS system being carried out and
does not indicate any abnormal condition. &
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ”
position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.
CAUTION
If the warning light behaves as
follows, the ABS system may not
be working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. . The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. The warning light comes on when
the ignition switch is turned tothe “ON ”position, but it does not
go out even when the vehicle
speed exceeds approximately 8
mph (12 km/h).
. The warning light comes on dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.
NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. . The warning light comes on right
after the engine is started but goes out
