7-2 Starting and operating
Starting and operatingFuel
„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.

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. T
Gasoline for cleaner air
Your use of gasoline with detergent addi-
tives will help prevent deposits from form-
ing 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 ma-
terials called oxygenates. Use of these fu-
els can also help keep the air cleaner. Ox-
ygenated blend fuels, such as MTBE (Me- thyl Tertiary Butyl ether) or ethanol (ethyl
or grain alcohol) may be used in your ve-
hicle, 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 oper-
ators if their gasolines contain detergents
and oxygenates and if they have been re-
formulated to reduce vehicle emissions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following. y
Fuel should be unleaded and have an
octane rating no lower than that specified
in this manual. y 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 AND if it is accompanied by suffi-
cient quantities of the proper cosolvents
and corrosion inhibitors required to pre-
vent damage to the fuel system. Do not
use fuel containing methanol EXCEPT un-der these conditions.y
If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a di fferent brand of gaso-
line before seeking service at your
SUBARU dealer.y Fuel system damage or driveability
problems which result from the use of im-
proper fuel are not covered under the
SUBARU Limited Warranty.
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 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.

cation, contact your SUBARU dealer. Replacement of brake pad and lining
The right front disc brake and the right rear
disc brake have audible wear indicators
on the brake pads. If the brake pads wear
close to their service limit, the wear indica- tor makes a very audible scraping noise
when the brake pedal is applied.
If you hear this scraping noise each time

Wheel balance
Each wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance caus-
es the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle’s straight-l ine stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not cor-
rectly balanced, have them checked and
adjusted by your SUBARU dealer. Also
have them adjusted after tire repairs and
after tire rotation.
NOTE
Loss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability.
Contact your SUBARU dealer if you no-
tice abnormal tire wear.
*: The suspension system is designed to hold
each wheel at a certain alignment (relative to
the other wheels and to the road) for optimum
straight-line stability and cornering perfor-
mance. „
Wear indicators
1) New tread
2) Worn tread
3) Tread wear indicator
Each tire incorporates a tread wear indica-
tor, which becomes visible when the depth
of the tread grooves decreases to 0.063 in
(1.6 mm). A tire must be replaced when
the tread wear indicator appears as a solid
band across the tread.
NOTE For safety, inspect th e tire tread regu-
larly and replace the tires before their
tread wear indicators become visible. „ Tire rotation
12 3
B00327
When a tire’s tread wear indicator
becomes visible, the tire is worn be-
yond the acceptable limit and must
be replaced immediately. With a tire
in this condition, driving at high
speeds in wet weather can cause
the vehicle to hydroplane. The re-
sulting loss of vehicle control can
lead to an accident.
