low 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 con-
ditioner 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 op-
eration 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 conditioning sys-
tem.
„ Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is de-
signed to temporarily shut off during air
conditioner operation whenever the accel-
erator is fully depressed such as during
rapid acceleration 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 (if
equipped)
If your vehicle’s air conditioning system is
equipped with an air filtration system, re-
place the filter element according to the
replacement schedule shown in the fol-
lowing. This schedule should be followed
to maintain the filter’s dust collection abili-
ty. Under extremely dusty conditions, the
filter should be replaced more frequently.
It is recommended that you have your fil-
ter checked or replaced by your SUBARU
dealer. For replacement, use only a genu-
ine SUBARU air filter kit.
Replacement schedule:
Every 12 months or 7,500 miles (12,000
km) whichever comes first
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter:
– Reduction of the air flow throughthe vents.
– Windshield gets easily fogged or misted.

„Fuel requirements
T Non-turbo models
The 2.5-liter non-turbo engine is designed
to operate using unleaded gasoline with
an octane rating of 87 AKI or higher. T Turbo models
The 2.5-liter turbo engine is designed to
operate using premium unleaded gasoline
with an octane rating of 91 AKI or higher.
If premium unleaded gasoline is not avail-
able, regular unleaded gasoline with an
octane rating of 87 AKI or higher may be
temporarily used. For optimum engine
performance and driveability, it is required
that you use premium grade unleaded
gasoline.
NOTE
Be sure to use premium unleaded gas-
oline of 91 AKI or higher for a 2.5-liter
turbo engine model. If other gasoline
(lower than 91 AKI) is used, knocking, reduced output and poor accelerator
response will result. T
Fuel octane rating
This octane rating is the average of the
Research Octane and Motor Octane num-
bers and is commonly referred to as the
Anti Knock Index (AKI).
Using a gasoline with a lower octane rat-
ing 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. T Unleaded gasoline
The neck of the fuel filler pipe is designed
to accept only an unleaded gasoline filler
nozzle. Under no circumstances should
leaded gasoline be used because it will
damage the emission control system and
may impair driveability and fuel economy. T Gasoline for California-certified LEV
Your vehicle was certified to California’s
low emission vehicle (LEV) standards as
indicated on the underhood tune-up label,
it is designed to optimize engine and
emission performance with gasoline that meets the clean burning low-sulfur Califor-
nia gasoline specifications. If you live in
any other state than California, your vehi-
cle will operate on gasoline meeting Fed-
eral specifications. Gasoline sold outside
California is permitted to have higher sul-
fur levels, which may affect the perfor-
mance of your vehicle’s catalytic convert-
er 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 vehicle to an authorized dealer for
service. T
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 deter-
mined that the condition is caused by the
type of fuel used, repairs may not be cov-
ered by your warranty.
Use of a fuel which is low in quality
or use of an inappropriate fuel addi-
tive may cause engine damage.

7-4 Starting and operating
1. To open the fuel filler lid, pull the lid re-
lease lever. The lever is on the floor at the
left of the driver’s seat.1) Open
2) Close 2. Remove the fuel filler cap by turning it
slowly counterclockwise.
3. Stop filling the tank after the fuel filler
pump automatically 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 under 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 y
You will see the “ ”
sign in the fuel gauge. This indicates
that the fuel filler door (lid) is located
on the right side of the vehicle. y 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” sec-
tion located in chapter 3.
(Turbo model only) Promptly put fuel in
the tank whenever the low fuel warning
light comes on. Engine misfires as a re-
sult of an empty tank could cause dam-
age to the engine.

y
Gasoline vapor is highly flamma-
ble. Before refueling, always first
stop the engine and make sure
that there are no lighted ciga-
rettes, open flames or electrical
sparks in the adjacent area.
yWhen opening the cap, do not re-
move the cap quickly. Fuel may be
under pressure and spray out of
the fuel filler neck especially in
hot weather, which may cause in-
jury.

7-6 Starting and operating
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.
The EPA has issued regulations for in-
specting the On-Board Diagnostic (OBD)
system as part of the state emissions in-
spection. The OBD system is designed to
detect engine and transmission problems
that might cause vehicle emissions to ex-
ceed allowable limits. These inspections
apply to all 1996 model year and newer
passenger cars and light trucks. Over 30
states plus the District of Columbia have
implemented the OBD system inspection. yThe inspection of the OBD system con-
sists of a visual operational check of the
“CHECK ENGINE” warning light/mal-
function indicator lamp (MIL) and an ex-
amination of the OBD system with an
electronic scan tool while the engine is
running y A vehicle passes
the OBD system in-
spection if proper the “CHECK ENGINE”
warning light/MIL illumination is observed,
there is no stored diagnostic trouble
codes, and the OBD system readiness
monitors are complete. y A vehicle fails
the OBD inspection if the “CHECK ENGINE”
warning light/MIL is
not properly operating or there is one or
more diagnostic trouble codes stored in
vehicle’s computer with the “CHECK EN-
GINE” warning light/MIL illuminated.
y A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBD system readiness monitors “Not
Ready” is greater than one. Under this
condition, the vehicle operator should be
instructed to drive his/her vehicle for a few
days to set the monitors and return for an
emission re-inspection. y Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Preparing to drive
You should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition of
the tires. Also check tires for proper infla-
tion.
3. Look under the vehicle for any sign of
leaks.
4. Check that the hood and rear gate are
fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and
outside mirrors.
7. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
8. Check the operation of the warning and
indicator lights when the ignition switch is
turned to the “ON” position.
9. Check the gauges, indicator and warn-
ing lights after starting the engine.
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.

Starting the engine
„Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and acces-
sories.
3. Press the clutch pedal to the floor and
shift the shift lever into neutral. Hold the
clutch pedal to the floor while starting the
engine.
The starter motor will only operate when
the clutch pedal is pressed fully to the
floor.
4. Turn the ignition switch to the “ON” po-
sition and check the operation of the warn-
ing and indicator lights. Refer to the
“Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START”
position without depressing the accelera-
tor pedal. Release the key immediately af-
ter the engine has started. If the engine does not start, try the follow-
ing.
1) Turn the ignition switch to the “OFF”
position and wait for at least 10 sec-
onds. After checking that the parking
brake is firmly set, turn the ignition
switch to the “START” position while de-
pressing the accelerator pedal slightly
(about a quarter of the full stroke). Re-
lease the accelerator pedal as soon as
the engine starts.
2) If this fails to start the engine, turn the
ignition switch back to the “OFF” posi-
tion and wait for at least 10 seconds.
Then fully depress the accelerator ped-
al and turn the ignition switch to the
“START” position. If the engine starts,
quickly release the accelerator pedal.
3) If this fails to start the engine, turn the
ignition switch again to the “OFF” posi-
tion. After waiting for 10 seconds or
longer, turn the ignition switch to the
“START” position without depressing
the accelerator pedal.
4) If the engine still refuses to start, con-
tact your nearest SUBARU dealer for
assistance.
6. Confirm that all warning and indicator
lights have gone off after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the en-
gine warms up.
NOTE
The engine may be difficult to start
when the battery has been disconnect-
ed and reconnected (for maintenance
or other purposes). This difficulty is
caused by the electronically controlled
throttle’s self-diagnosis function. To
overcome it, keep the ignition switch in
the “ON” position for approximately 10
seconds before starting the engine. „ Automatic transmission vehi-
cle
1. Apply the parking brake.
2. Turn off unnecessary lights and acces-
sories.
3. Shift the selector lever to the “P” or “N”
position (preferably “P” position).
The starter motor will only operate when
the select lever is at the “P” or “N” position.
4. Turn the ignition switch to the “ON” po-
sition and check the operation of the warn-
ing and indicator lights. Refer to the
“Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START”
position without depressing the accelera-
tor pedal. Release the key immediately af-
ter the engine has started.
If the engine does not start, try the follow-
ing.
Do not operate the starter motor
continuously for more than ten sec-
onds. If the engine fails to start after
operating the starter for five to ten
seconds, wait for ten seconds or
more before trying again.

7-8 Starting and operating
1) Turn the ignition switch to the “OFF”
position and wait for at least 10 sec-
onds. After checking that the parking
brake is firmly set, turn the ignition
switch to the “START” position while de-
pressing the accelerator pedal slightly
(about a quarter of the full stroke). Re-
lease the accelerator pedal as soon as
the engine starts.
2) If this fails to start the engine, turn the
ignition switch back to the “OFF” posi-
tion and wait for at least 10 seconds.
Then fully depress the accelerator ped-
al and turn the ignition switch to the
“START” position. If the engine starts,
quickly release the accelerator pedal.
3) If this fails to start the engine, turn the
ignition switch again to the “OFF” posi-
tion. After waiting for 10 seconds or
longer, turn the ignition switch to the
“START” position without depressing
the accelerator pedal.
4) If the engine still refuses to start, con-
tact your nearest SUBARU dealer for
assistance.
6. Confirm that all warning and indicator
lights have gone out after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the en-
gine warms up.
While the engine is warming up, make
sure that the selector lever is at the “P” or “N” position and that the parking brake is
applied.
NOTE
The engine may be difficult to start
when the battery has been disconnect-
ed and reconnected (for maintenance
or other purposes). This difficulty is
caused by the electronically controlled
throttle’s self-diagnosis function. To
overcome it, keep the ignition switch in
the “ON” position for approximately 10
seconds before starting the engine.
Stopping the engine
The ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
If you restart the engine while the
vehicle is moving, shift the selector
lever into the “N” position. Do not
attempt to place the selector lever of
a moving vehicle into the “P” posi-
tion.
Do not stop the engine when the ve-
hicle is moving. This will cause loss
of power to the power steering and
the brake booster, making steering
and braking more difficult. It could
also result in accidental activation
of the “LOCK” position on the igni-
tion switch, causing the steering
wheel to lock.

7-16 Starting and operating
when a tire is punctured. This could cause
a loss of control of the vehicle. Keep driv-
ing straight ahead while gradually reduc-
ing speed. Then slowly pull off the road to
a safe place. „Brake system
T Two separate circuits
Your vehicle has two separate circuit
brake systems. Each circuit works diago-
nally across the vehicle. If one circuit of
the brake system should fail, the other half
of the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle. T Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn off the engine while driving because
that will turn off the brake booster, result-
ing in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to push the pedal much harder
than normal and the braking distance will
increase. „
Disc brake pad wear warning
indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, imme-
diately have your vehicle checked by your
SUBARU dealer. ABS (Anti-lock Brake Sys-
tem)
700040
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident. y
The ABS system does not always
decrease stopping distance. You
should always maintain a safe fol-
lowing distance from other vehi-
cles.
y When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be longer
for a vehicle with the ABS system
than one without. When driving
under these conditions, therefore,
reduce your speed and leave am-
ple distance from other vehicles.
