Defrosting or defogging
To direct warm air to the windshield and front door win-
dows:
1. Set the air flow control dial to the “ ” position.
2. Set the temperature control dial to the red side.
3. Set the fan speed control dial at the highest speed.
The air conditioner compressor automatically oper-
ates when the air flow control dial set in the “ ” or
“ ” position to provide better defogging perfor-
mance.
However, the air conditioner indicator light does not
come on at this time. Automatic climate control system (if
equipped)
NOTE
Operate the automatic climate control 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 compartment is sufficiently cool,
the air conditioner compressor does not operate.
For efficient defogging or dehumidifying in cold
weather, press the “A/C” switch on. 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” indicator light on
the control panel comes on.
The automatic climate control system automatically
controls outlet air temperature, fan speed, air flow dis-
tribution air-inlet control, and air conditioner compres-
sor operation. It activates when the “AUTO” switch is
pressed, and is used in conjunction with the Temper-
ature control dial to maintain a constant, comfortable
climate within the passenger compartment.
The temperature can be set within a range of 65 –

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 accerela-
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.

Interior equipment
Accessory power outlets are provided in the center
console and in the cargo area.
Electrical power (12V DC) from the battery is on tap at
thesocketwhentheigniti
on switch is either in the
“ACC” or “ON” position.
You can use an in-car use electrical appliance by con-
necting it to the socket.
When both outlets are used at the same time, the total
power consumption of the electric appliances must be
120W or less.
Do not attempt to use a cigarette lighter in the accessory power outlet.
Do 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. 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. 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. 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. 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

Do not hold the lighter pushed in, because it
will overheat.
Using as an accessory power outlet
Electrical power (12V DC) from the battery is on tap at
the socket when the ignition switch is either in the
“ACC”or“ON”position.
If you use the socket as an accessory power outlet,
take the following precautions.
When the socket is not in use, always put the cap on
the socket to prevent any foreign object from entering
it.
Use only in-car use electrical appliances
which are designed for 12V DC and which con-
sume less than 120W. Overloading the socket
can cause a short circuit. Do not use double
adapters or more than one electrical appliance. If the plug on your electric appliance is either
too loose or too tight for the socket, this can re-
sult in a poor contact or cause the plug to get
stuck. Only use plugs that fit properly.
Use of an electric appliance in the socket for
alongperiodoftimewhiletheengineisnot
running can cause battery discharge. 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.
If the socket has been used for electrical appliances,
damage may have been done to the internal mecha-
nism that causes a cigarette lighter to “pop out” after
its element has been heated. For that reason, a ciga-
rette lighter, even if it is a genuine part, should not be
used in the socket. If you want to use the socket for a
cigarette lighter again, or to protect your purchaser be-
fore you sell your car, have your SUBARU dealer re-
place the socket with a new one.

Fuel
Use of a fuel which is low in quality or use of an
inappropriate fuel additive may cause engine
damage.
Fuel requirements
The 2.5 Liter engine is designed to operate using un-
leaded gasoline with an octane rating of 87 AKI or
higher. Fuel octane rating
This octane rating is the average of the Research Oc-
tane and Motor Octane numbers and is commonly re-
ferred to as the Anti Knock Index (AKI).
Using a gasoline with a lower octane rating can cause
persistent and heavy knocking, which can damage the
engine. Do not be concerned if your vehicle some-
times knocks lightly when you drive up a hill or when
you accelerate. See your dealer or a qualified service
technician if you use a fuel with the specified octane
rating and your vehicle knocks heavily or persistently.
Unleaded gasoline
The neck of the fuel filler pipe is designed to accept
only an unleaded gasoline filler nozzle. Under no cir-
cumstances should leaded gasoline be used because
it will damage the emission control system and may
impair driveability and fuel economy. Gasoline for California-certified LEV
Your vehicle was certified to California’s low emission
vehicle (LEV) standards as indicated on the under-
hood tune-up label. It is designed to optimize engine
and emission performance with gasoline that meets
the clean burning low-sulfur California gasoline speci-
fications. If you live in any other state than California,
your vehicle will operate on gasoline meeting Federal
specifications. Gasoline sold outside California is per-
mitted to have higher sulfur levels, which may affect
the performance of your vehic le’s catalytic converter
and may produce a sulfur exhaust odor or 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 vehi-
cle to an authorized dealer for service. 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

1) Open
2) Close
2. Remove the fuel filler cap by turning it slowly coun-
terclockwise.
Gasoline vapor is highly flammable. Before
refueling, always first stop the engine and make
sure that there are no lighted cigarettes, open
flames or electrical sparks in the adjacent area. When opening the cap, do not remove the
cap quickly. Fuel may be under pressure and
spray out of the fuel filler neck especially in hot
weather, which may cause injury.
3. Stop filling the tank after the fuel filler pump auto-
matically stops. Do not add any more fuel.
4. Put the cap back on, turn it clockwise until you hear
a clicking noise. Be certain not to catch the tether un-
der the cap while tightening.
5. Close the fuel filler lid completely.
If you spill any fuel on the painted surface, rinse it off
immediately. Otherwise, the painted surface could be
damaged.
NOTE
If the fuel filler cap is not tightened until it clicks or
if the tether is caught under the cap, the CHECK
ENGINE warning light may come on. Refer to the
“Warning and indicator lights” section located in
chapter 3.
Never add any cleaning agents to the fuel
tank. The addition of a cleaning agent may
cause damage to the fuel system. Make sure that the cap is tightened until it
clicks to prevent fuel spillage in the event of an
accident.

states using two-wheel dynamometers in their emis-
sion testing programs have EXEMPTEDSubaru AWD
vehicles from the portion of the testing program that in-
volves a two-wheel dynamometer.
There are some states that use four-wheel dynamom-
eters in their testing programs. When properly used,
that equipment will not damage an AWD Subaru vehi- cle.
Under no circumstances should the rear wheels be
jacked off the ground, nor should the driveshaft be dis-
connected for state emission testing.
Testing of an All-Wheel Drive vehicle must
NEVERbeperformedonasingletwo-wheeldy-
namometer. Attempting to do so will result in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.
Resultant vehicle damage due to improper test-
ing is not covered under the SUBARU Limited
Warranty and is the responsibility of the state inspection program or its contractors or licens-
ees.
The EPA has issued regulations for inspecting the On-
Board Diagnostic (OBD) system as part of the state
emissions inspection. The OBD system is designed to
detect engine and transmission problems that might
cause vehicle emissions to exceed allowable limits.
These inspections apply to all 1996 model year and
newer passenger cars and light trucks. Several states
plus the District of Columbia have opted to start the
OBD system inspection prior to the required EPA reg-
ulation effective date of January 1, 2002. Other states
will add OBD system inspection in 2002. The inspection of the OBD system consists of a vi-
sual operational check of the “CHECK ENGINE”
warning light/malfunction indicator lamp (MIL) and an
examination of the OBD system with an electronic
scan tool while the engine is running A vehicle passes
the OBD system inspection if
proper the “CHECK ENGINE” warning light/MIL illu-
mination is observed, there is nostored diagnostic
trouble codes, and the OBD system readiness moni-
tors are complete. A vehicle fails
the OBD inspection if the “CHECK
ENGINE” warning light/MIL is not properly operating
