Fuel
224need to add any fuel system cleaning
agents 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 15% ethanol for the proper operation
of your SUBARU.
Do not use any gasoline that contains
more than 15% ethanol, including from
any pump labeled E30, E50 or E85 (which
are only some examples of fuel containing
more than 15% 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 oper-
ators if their gasolines contain detergents
and oxygenates and if they have been
reformulated to reduce vehicle emissions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
 Fuel should be unleaded and have an
octane 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
ONLY if it does not exceed 5% of the fuel
mixture AND if it is accompanied by suffi-
cient quantities of the proper cosolvent
and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanol EXCEPT
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.

5. Set the fuel filler cap on the cap holder
inside the fuel filler lid.
WARNING
Before opening the fuel filler cap,
first touch the veh icle body or a
metal portion of the fuel pump or
similar object to discharge any
static electricity that may be present
on your body. If your body is carry-
ing 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 refueling
is in progress.
WARNING
 Gasoline vapor is highly flam-
mable. Before refueling, always
turn the ignition switch to the
“OFF” position first and then
close all vehicle doors and
windows. Make sure that there
are no lighted cigarettes, open
flames or electrical sparks in the
adjacent area. Only handle fuel
outdoors. Quickly wipe up any
spilled fuel.

Preparing to Drive
228have 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/
malfunction indicator light (MIL) and an
examination 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
observed, 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 a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle’s computer.
 A state emission in spection 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
replaced 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 readi-
ness monitors and return for an emission
re-inspection. 
Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
7-3. 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.
4. Check that no small animals enter the
engine compartment.
5. Check that the hood and trunk 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
warning lights after starting the engine.

Button Start SystemRefer to "Operating Range for Push-
Button Start System" P125.■ General Precautions When
Starting Engine
NOTEIt may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This
difficulty is caused by the electroni-
cally controlled throttle’s self-diag-
nosis function. To overcome it, keep
the ignition switch in the “ON” position
for approximately 10 seconds before
starting the engine.
 Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
 After the engine starts, the engine
speed will be kept high.
CAUTION
Small animals trapped in the cool-
ing fan and belt of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
WARNING
Never start the engine from
outside the vehicle. It may result
in an accident. 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
poisoning.
 Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
 If the engine is stopped during
driving, the catalyst may overheat
and burn. When starting the engine, be sure
to sit in the driver’s seat.
