„Fuel requirements
T 2.5-liter 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 2.5-liter turbo models and 3.0-liter models
The 2.5-liter turbo engine and 3.0-liter en-
gine are designed to operate using premi-
um unleaded gasoline with an octane rat-
ing of 91 AKI or higher. If premium unlead-
ed gasoline is not available, regular un-
leaded gasoline with an octane rating of
87 AKI or higher may be temporarily used.
For optimum engine performance and
driveability, it is required (for 2.5-liter turbo
models), and recommended (for 3.0-liter
models) that you use premium grade un-
leaded 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 f iller 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 California fuel
If your vehicle was certified to California
Emission Standards as indicated on the underhood tune-up label,
it is designed to
optimize engine and emission control sys-
tem performance with gasoline that meets
the clean burning low-sulfur California
gasoline specifications. If you live in any
other state than Calif ornia, your vehicle
will operate on gasoline meeting Federal
specifications. Gasoline sold outside Cali-
fornia is permitted to have higher sulfur
levels, which may affect the performance
of your vehicle’s catalytic converter and
may produce a sulfur exhaust odor or
smell. SUBARU recomm ends 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. The CHECK ENGINE warning
light/Malfunction indicator lamp may also
turn on. If this occurs, return to your autho-
rized SUBARU dealer for diagnosis. If it is
determined that the condition is caused by
the type of fuel us ed, repairs may not be
covered by your warranty. 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-
Use of a fuel which is low in quality
or use of an inappropriate fuel addi-
tive may cause engine damage.

3. Remove the fuel filler cap by turning it
slowly counterclockwise.
4. Stop filling the tank after the fuel filler
pump automatically cl icks off. Do not add
any more fuel.
5. 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.
6. 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.

y
When opening the cap, do not re-
move the cap quickly. Fuel may be
under pressure and spray out ofthe fuel filler neck especially in
hot weather, which may cause in-
jury.

y Never add any cleaning agents to the fuel tank. The addition of a
cleaning agent may cause dam-
age to the fuel system.
y Make sure that the cap is tight-
ened until it clicks to prevent fuel
spillage in the event of an acci-
dent.
y Do not let fuel sp ill on the exterior
surfaces of the vehicle. Fuels may
cause paint damage, which is not
covered under the SUBARU Limit-
ed Warranty.

Starting and operating 7-7
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 li ght trucks. Over 30
states plus the Distr ict of Columbia have
implemented the OBD system inspection. y The inspection of the OBD system con-
sists of a visual operational check of the “ CHECK ENGINE ” warning light/malfunc-
tion indicator lamp (MIL) and an examina-
tion 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, trunk (Sedan)
and rear gate (Station wagon) 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.

“Warning and indicator lights” section
(chapter 3).
5. Turn the ignition sw itch 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
(approximately a quarter of the full
stroke). Release th e accelerator pedal
as soon as the engine starts.
2) If this fails to start the engine, turn theignition 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.

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. „

4) If the engine still refuses to start, con-
tact your nearest SUBARU dealer forassistance.
6. Confirm that all warning and indicator
lights have gone out after the engine has
started. The fuel in jection 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.
Stopping the engine
The ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
Manual transmission
The manual transmission is a fully syn-
chromeshed, 5-forward-speed and 1-re-
verse-speed transmission.
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 a ccidental activation
of the “LOCK” position on the igni-
tion switch, causing the steering
wheel to lock.Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral posi-
tion. Engine braking has no effect in
either of these conditions and the
risk of an accident is consequently
increased. Shift into reverse ONLY when the
vehicle has completely stopped. It
may cause damage to the transmis- sion to try shifti ng into reverse
when the vehicle is moving.

Starting and operating 7-15
– CONTINUED –
Gearshifts can be performed using the se-
lector lever.
Using the selector lever
Shift to the next-higher gear by briefly
pushing the selector
lever toward the “+”
end of the manual gate.
Shift to the next-lower gear by briefly pull-
ing the selector lever toward the “–” end of
the manual gate.
NOTE
Please read the following points care-
fully and bear them in mind when using
the manual mode.y The transmission does not automati-
cally shift up in the manual mode. Per-
form gearshifts in accordance with
road conditions so that the tachometer
needle does not enter the red zone. If the engine speed reaches a predeter-
mined level, a fuel-cut function will op-
erate. Shift up if this happens.y
If you attempt to sh ift down when the
engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible. y If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.y You can perform a skip-shift (for ex-
ample, from 4th to 2nd) by operating
the selector lever twice in rapid suc-
cession. y The transmission automatically se-
lects 1st gear when the vehicle stops moving. y If the temperature of the automatic
transmission fluid becomes too high,
the “AT OIL TEMP” warning light will
come on and upshifts to 4th gear will
not be possible. Immediately stop the
vehicle in a safe place and let the en-
gine idle until the warning light goes off. „
Maximum speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When down shifting, it is important to con-
firm that the current vehicle speed is not in
excess of the Maximum Allowable Speed
of the gear which is about to be selected.
700111
When down shifting, ensure that the
vehicle is not travelling at a speed
exceeding the Maximum Allowable
Speed for the gear which is about to
be selected. Failure to observe this
precaution can lead to engine over-
revving and this in turn can result in
engine damage.
In addition, sudden application of
engine braking caused by down
shifting when the vehicle is travel-
ling on a slippery surface can lead to
wheel locking; as a consequence,
control of the vehicle may be lost
and the risk of an accident in-
creased.

7-22 Starting and operating
transmission will automatically switch
back from manual mode to normal mode.
NOTE
Please read the following points care-
fully and bear them in mind when using the manual mode.yWhen the temperature of the auto-
matic transmission fluid is higher than
normal, warning beeps are emitted and
the shift position in dicator shows “–”.
If these warnings are issued, deselect
the manual mode to protect the auto-
matic transmission from damage. y When the temperature of the engine
oil is higher than normal, warning
beeps are emitted and the shift posi-
tion indicator shows “–”. If these warn-
ings are issued, deselect the manual
mode to protect th e engine from dam-
age. (3.0-liter models only)y The transmission does not automati-
cally shift up in the manual mode. Per-
form gearshifts in accordance with
road conditions so that the tachometer
needle does not enter the red zone. If
the engine speed reaches a predeter-
mined level, a fuel-cut function will op-
erate. Shift up if this happens. (Also, in
the case of a 3.0-liter model, the trans-
mission may automatically shift up to
protect the engine.) y If you attempt to shift down when the engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible. y
If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond. y You can perform a skip-shift (for ex-
ample, from 4th to 2nd) by operating
the selector lever or a steering-wheel
switch twice in rapid succession.y The transmission automatically se-
lects 1st gear when the vehicle stops
moving. y If the temperature of the automatic
transmission fluid becomes too high,
the “AT OIL TEMP” warning light will
come on and upshifts to 5th gear will
not be possible. Immediately stop the
vehicle in a safe place and let the en-
gine idle until the warning light goesoff. „

7-26 Starting and operating
„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 inspected by the
nearest SUBARU dealer. ABS (Anti-lock Brake Sys-
tem)
The ABS system prev
ents 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 no t 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.
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 road, 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.
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.
