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.

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.

Starting and operating 7-17
– CONTINUED –
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. This helps prevent the loss of steering
control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h). „
ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition. „
ABS warning light
1) U.S.-spec. models
2) Canada-spec. models
The ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately two
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.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal. y The warning light comes on right af-
ter the engine is started but goes out
y
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 op-
eration of the ABS system.

700333 If the warning light behaves as fol-
lows, 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. y
The warning light does not come
on when the ignition switch is
turned to the “ON” position.
y The warning light comes on when
the ignition switch is turned to the
“ON” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
y 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.

motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the system in-
spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.
Parking your vehicle
y
Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
yIf at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest SUB-
ARU dealer for repair.
yNever leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent opera-
tion of the vehicle. Also, on hot or
sunny days, the temperature in a
closed vehicle could quickly be-
come high enough to cause se-
vere or possibly fatal injuries to
people.
yDo not park the vehicle over flam-
mable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
yBe sure to stop the engine if you
take a nap in the vehicle. If engine
exhaust gas enters the passenger
compartment, occupants in the
vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.

Driving tips 8-7

thrown around in the vehicle and cause in-
jury. Do not pile heavy loads on the roof.
Those loads raise the vehicle’s center of
gravity and make it more prone to tip over. y
If you must rock the vehicle to free it
from sand or mud, depress the accelera-
tor pedal slightly and move the selector le-
ver back and forth between “D” and “R” re-
peatedly. Do not race the engine. For the
best possible traction, avoid spinning the
wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT). y Never equip your vehicle with tires larg-
er than those specified in this manual.y Frequent driving of an AWD vehicle un-
der hard-driving conditions such as rough
roads or off roads will necessitate more
frequent replacement of engine oil, brake
fluid and transmission oil than that speci-
fied in the maintenance schedule de-
scribed in the “Warranty and Maintenance
Booklet”.
Remember that damage done to your
SUBARU while operating it off-road and
not using common sense precautions
such as those listed above is not eligible
for warranty coverage.y Wash the vehicle’s underbody after off-
road driving. Suspension components are particularly prone to dirt buildup, so they
need to be washed thoroughly.
Winter driving „
Operation during cold weath- er
Carry some emergency equipment, such
as tire chains, a window scraper, a bag of
sand, flares, a small shovel, and jumper
cables.
Check the battery and cables. Cold tem-
peratures reduce battery capacity. The
battery must be in good condition to pro-
vide enough power for cold winter starts.
Use an engine oil of proper grade and vis-
cosity for cold weather. Heavy summer oil
will cause harder starting.
