Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.&Fuel requirements!STI
The engine is designed to operate at
maximum performance usingunleaded
gasolinewith an octane rating of93 AKI
(98 RON) or higher. If 93 AKI (98 RON)
fuel is not readily available in your area,
unleaded gasoline with an octane rating of
91 AKI (95 RON) may be used with no
detriment to engine durability or driveabil-
ity. However, you may notice a slight
decrease in maximum engine perfor-
mance while using 91 AKI (95 RON) fuel.
Use of 91 AKI (95 RON) fuel will not affect
your warranty coverage.
!Except STI
The engine is designed to operate using
unleaded gasolinewith an octane rating
of91 AKI (95 RON) or higher. If 91 AKI
(95 RON) fuel is not readily available,
unleaded gasoline with an octane rating of87 AKI (90 RON) may be used.
Regular unleaded gasoline with an octane
rating of 87 AKI (90 RON) or higher may
also be used. Using regular unleaded
gasoline will not be detrimental to engine
durability, nor will it affect your warranty
coverage. However, depending on your
driving habits and conditions, you may
notice a decrease in maximum engine
performance, fuel economy or slight en-
gine vibration or knocking. If you experi-
ence any of these conditions while using a
lower octane rated fuel, you may want to
return to using 91 AKI (95 RON) octane
rated fuel as soon as possible. Addition-
ally, if your vehicle knocks heavily or
persistently, the use of 91 AKI (95 RON)
or higher grade unleaded gasoline is
required.
!Fuel octane rating
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 sometimes
knocks lightly when you drive up a hill or
when you accelerate. Contact your
SUBARU dealer if you use a fuel with the
specified octane rating and your vehicle
knocks heavily or persistently.!RON
This octane rating is the Research Octane
Number.
!AKI
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).
!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.
!Gasoline for California-certified
LEV
If 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 Cali-
fornia gasoline specifications. If you live in
any other state than California, your
vehicle will operate on gasoline meeting
Federal specifications. Gasoline sold out-
side California is permitted to have higher
sulfur levels, which may affect the perfor-
mance of your vehicle’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 vehicle to an authorized dealer for
service.
!MMT
Some gasoline contains an octane-enhan-
cing additive called MMT (Methylcyclo-
pentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/Mal-
function indicator light may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not be
covered by your warranty.
!Gasoline for cleaner air
Your use of gasoline with detergent ad-
ditives will help prevent deposits from
forming 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 cleaningagents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as ethanol
(ethyl or grain alcohol) may be used in your
vehicle, but should contain no more than
10% ethanol for the proper operation of
your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from any
pump labeled E15, E30, E50 or E85 (which
are only some examples of fuel containing
more than 10% ethanol).
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 op-
erators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
.Fuel should be unleaded and have anoctane rating no lower than that specified
in this manual.
.Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLYif it does not exceed 5% of the fuel
mixtureANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanolEXCEPT
under these conditions.
.If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
.Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
CAUTION
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.

&Fuel filler lid and cap!Refueling
Only one person should be involved in
refueling. Do not allow others to approach
the area of the vehicle near the fuel filler
pipe while refueling is in progress.
Be sure to observe any other precautions
that are posted at the service station.
Fuel lid release lever1. To open the fuel filler lid, pull the lid
release lever up. The lever is on the floor at
the left of the driver’s seat.
WARNING
Before opening the fuel filler cap,
first touch the vehicle body or a
metal portion of the fuel pump or
similar object to discharge any sta-
tic electricity that may be present on
your body. If your body is carrying
an electrostatic charge, there is a
possibility that an electric spark
could ignite the fuel, which could
burn you. To avoid acquiring a new
static electric charge, do not get
back into the vehicle while refuelingis in progress.
1) Open
2) Close2. Remove the fuel filler cap by turning it
slowly counterclockwise.
WARNING
.Gasoline vapor is highly flam-
mable. Before refueling, always
first stop the engine and close all
vehicle doors and windows.
Make sure that there are no
lighted cigarettes, open flames
or electrical sparks in the adja-
cent area. Only handle fuel out-
doors. Quickly wipe up any
spilled fuel.

.When opening the cap, grasp it
firmly and turn it slowly to the left.
Do not remove the cap quickly.
Fuel may be under pressure and
spray out of the fuel filler neck,
especially in hot weather. If you
hear a hissing sound while you
are removing the cap, wait for the
sound to stop and then slowly
open the cap to prevent fuel from
spraying out and creating a fire
hazard.3. Set the fuel filler cap on the cap holder
inside the fuel filler lid.
WARNING
.When refueling, insert the fuel
nozzle securely into the fuel filler
pipe. If the nozzle is lifted or not
fully inserted, its automatic stop-
ping mechanism may not func-
tion, causing fuel to overflow the
tank and creating a fire hazard.
.Stop refueling when the auto-
matic stop mechanism on the
fuel nozzle activates. If you con-
tinue to add fuel, temperature
changes or other conditions
may cause fuel to overflow from
the tank and create a fire hazard.
4. Stop filling the tank after the fuel filler
pump automatically stops. 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.
CAUTION
Make sure that the cap is tightened
until it clicks to prevent fuel spillage
in the event of an accident.
6. Close the fuel filler lid completely.
CAUTION
If you spill any fuel on the painted
surface, rinse it off immediately.
Otherwise, the painted surface
could be damaged.NOTE.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.
.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/malfunction indicator
light may illuminate. Refer to“CHECK
ENGINE warning light/Malfunction in-
dicator light”F3-16.
CAUTION
.Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
.After refueling, turn the cap
clockwise until it clicks to ensure
that it is fully tightened. If the cap
is not securely tightened, fuel
may leak out while the vehicle is

being driven or fuel spillage
could occur in the event of an
accident, creating a fire hazard.
.Do not let fuel spill on the exterior
surfaces of the vehicle. Because
fuel may damage the paint, be
sure to wipe off any spilled fuel
quickly. Paint damage caused by
spilled fuel is not covered under
the SUBARU Limited Warranty.
.Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting and your fuel tank
and emission control system
may be damaged. It could also
lead to fuel spillage and a fire.
.Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank could
cause damage to the engine.
Continuing to operate your vehi-
cle at an extremely low fuel level
may result in a reduction of
engine performance.
State emission testing
(U.S. only)
WARNING
Only use a four-wheel dynamometer
when testing an All-Wheel Drive
(AWD) model.
TestingofanAWDmodelmust
NEVER be performed on a single
two-wheel dynamometer. Attempt-
ing to do so will result in uncon-
trolled vehicle movement and may
cause an accident or injuries to
persons nearby.
CAUTION
.At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
.Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program orits contractors or licensees.
California and a number of federal states
have Inspection/Maintenance programs to
inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspection
of the OBDII system.
.The inspection of the OBDII system
consists of a visual operational check of
the“CHECK ENGINE”warning light/mal-
function indicator light (MIL) and an ex-
amination of the OBDII system with an
electronic scan tool.
.A vehicle passes the OBDII system
inspection if proper operation of the
“CHECK ENGINE”warning light is ob-

served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
.A vehicle fails the OBDII inspection if
the“CHECK ENGINE”warning light is not
properly operating (light is illuminated or is
not working due to faulty LED [Light
Emitting Diode]) or there is one or more
diagnostic trouble codes stored in the
vehicle’s computer.
.A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors“NOT
READY”is greater than one. If the
vehicle’s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a
few days to reset the readiness monitors
and return for an emission re-inspection.
.Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being puton a dynamometer, tell your emission
inspector not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer.Otherwise, serious transmis-
sion damage will result.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
program have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer. There are some states that
use four-wheel dynamometers in their
testing program. When properly used, this
equipment should not damage a SUBARU
AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected in
an attempt to bypass AWD for state
emission testing. An AWD vehicles must
be tested using an AWD dynamometer
with all 4 wheels driven and loaded.
Preparing to driveYou 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
inflation.
3. Look under the vehicle for any sign of
leaks, and check that no small animal is
under the vehicle.
4. Check that no small animal enters the
engine compartment.
5. Check that the hood and trunk lid are
fully closed.
6. Check the adjustment of the seat.
7. Check the adjustment of the inside and
outside mirrors.
8. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
9. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the“ON”position.
10. Check the gauges, indicator and warn-
ing lights after starting the engine.

gine&General precautions when
starting/stopping engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
.Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can cre-
ate a fire hazard at high tempera-
tures.
.Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
CAUTION
.Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
.When starting the engine, be sureto sit in the driver’s seat (except
when using the remote engine
start system).
NOTE.Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
.Until the engine is warmed up suffi-
ciently, the engine speed is maintained
high. The engine speed will gradually
drop as the engine warms up.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly such
as a rapid start-up and a rapid accel-
eration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
