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 different 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.

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.
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
1) Open
2) Close2. 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
yYou 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 of
the fuel filler neck especially in
hot weather, which may cause in-
jury.

yNever 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 spill on the exterior
surfaces of the vehicle. Fuels may
cause paint damage, which is not
covered under the SUBARU Limit-
ed Warranty.

State emission testing (U.S. only)At state inspection time, remember to
tell your inspection or service station
in advance not to place your SUBARU
AWD vehicle on a two-wheel dyna-
mometer. Otherwise, serious transmis-
sion damage will result.
Some states have started using dyna-
mometers in their state inspection pro-
grams in order to meet their obligation un-
der federal law to implement stricter vehi-
cle emission standards to reduce air pollu-
tion from cars. A dynamometer is a tread-
mill or roller-like testing device that allows
your vehicle’s wheels to turn while the ve-
hicle remains in one place. Depending on
the severity of a state’s air pollution prob-
lems, the states must adopt either a “ba-
sic” or “enhanced” vehicle emission in-
spection test. Normally, a portion of the
basic emission test consists of an emis-
sion inspector inserting an analyzer probe
into the exhaust pipe of an idling vehicle
for a short period of time. States with more
severe air pollution problems are required
to adopt an enhanced vehicle emission
test. This test simulates actual driving
conditions on a dynamometer and permits
more accurate measurement of tailpipe emitted pollution than the basic emission
test.
The U.S. Environmental Protection Agen-
cy (EPA) and states using two-wheel dy-
namometers in their emission testing pro-
grams have
EXEMPTED SUBARU AWD
vehicles from the portion of the testing
program that involves a two-wheel dyna-
mometer.
There are some states that use four-wheel
dynamometers in their testing programs.
When properly used, that equipment will
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.
y 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 might be
damaged.
Testing of an All-Wheel Drive vehi-
cle must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in un-
controlled vehicle movement and
may cause an accident or injuries to
persons nearby.

Starting and operating
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/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 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 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.NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Resultant vehicle damage due to im-
proper testing is not covered under
the SUBARU Limited Warranty and
is the responsibility of the state in-
spection program or its contractors
or licensees.
