The indicator light located on the combi-
nation meter will illuminate when the front
fog lights are on. Wiper and washer
WARNING
In freezing weather, do not use the
windshield washer until the wind-
shield is sufficiently warmed by the
defroster.
Otherwise the washer fluid can
freeze on the windshield, blocking
your view.
CAUTION
. Do not operate the washer con-
tinuously for more than 10 sec-
onds, or when the washer fluid
tank is empty. This may cause
overheating of the washer motor.
Check the washer fluid level
frequently, such as at fuel stops.
. Do not operate the wipers when
the windshield or rear window is
dry. This may scratch the glass,
damage the wiper blades and
cause the wiper motor to burn
out. Before operating the wiper
on a dry windshield or rear
window, always use the wind-
shield washer. .
In freezing weather, be sure that
the wiper blades are not frozen to
the windshield or rear window
before switching on the wipers.
Attempting to operate the wiper
with the blades frozen to the
window glass could cause not
only the wiper blades to be
damaged but also the wiper mo-
tor to burn out. If the wiper
blades are frozen to the window
glass, be sure to operate the
defroster, wiper deicer (if
equipped) or rear window defog-
ger before turning on the wiper.
. If the wipers stop during opera-
tion because of ice or some other
obstruction on the window, the
wiper motor could burn out even
if the wiper switch is turned off. If
this occurs, promptly stop the
vehicle in a safe place, turn the
ignition switch to the “LOCK ”
position and clean the window
glass to allow proper wiper op-eration.
. Use clean water if windshield
washer fluid is unavailable. In
areas where water freezes in
winter, use SUBARU Windshield
Washer Fluid or the equivalent.

Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.
& Fuel requirements
! 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. ! 2.5-liter turbo models
The 2.5-liter turbo engine is designed to
operate using premium unleaded gasoline
with an octane rating of 91 AKI or higher. If
premium unleaded gasoline is not avail-
able, regular unleaded gasoline with an
octane rating of 87 AKI or higher may be
temporarily used. For optimum engine
performance and driveability, it is required
that you use premium grade unleadedgasoline. NOTE
Be sure to use premium unleaded
gasoline of 91 AKI or higher for a 2.5-
liter turbo engine model. If other gaso-
line (lower than 91 AKI) is used, knock-
ing, reduced output and poor accelera-
tor response will result. !
3.0-liter models
The 3.0-liter engine is designed to operate
using unleaded gasoline with an octane
rating of 91 AKI or higher. Regular
unleaded gasoline with an octane rating
of 87 AKI or higher may be used. However
for optimum engine performance and
driveability, it is recommended that you
use 91 AKI or higher grade unleaded
gasoline. You may experience reduced
output, poor accelerator response, and
reduced fuel economy when using gaso-
line with an octane rating lower than 91
AKI, depending on your driving habits and
conditions. If you experience any of these
conditions while using a lower octane
rated fuel, you may want to return to using
91 AKI octane rated fuel as soon as
possible. Additionally, if your vehicle
knocks heavily or persistently, or if you
are driving with heavy loads such as when
towing a trailer, the use of 91 AKI or higher
grade unleaded gasoline is required. !
Fuel octane rating
This octane rating is the average of the
Research Octane and Motor Octane
numbers and is commonly referred to as
the Anti Knock Index (AKI).
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. 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. ! 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. ! 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
system performance with gasoline that
meets the clean burning low-sulfur Cali-
fornia gasoline specifications. If you live in
any other state than California, your Starting and operating
7-3
– CONTINUED –

7-4Starting and operating
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. The CHECK ENGINE warning
light/malfunction indicator lamp may also
turn on. If this occurs, return to your
authorized SUBARU dealer for diagnosis.
If it is determined that the condition is
caused by the type of fuel used, repairs
may not be covered by your warranty. ! 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-
function indicator lamp 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
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.
Your use of gasoline with detergent
additives 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 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 MTBE
(Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in
your vehicle, 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
operators 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 thefollowing. .
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 ANDif 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 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. & Fuel filler lid and cap
CAUTION
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.
! Refueling
WARNING
Gasoline vapor is highly flammable.
Before refueling, always first stop
the engine and make sure that there
are no lighted cigarettes, open
flames or electrical sparks in the
adjacent area.
CAUTION
. Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system. .
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels
may cause paint damage, which
is not covered under the
SUBARU Limited Warranty.
1. To open the fuel filler lid, pull the lid
release lever up. The lever is on the floor

WARNING
When opening the cap, do not
remove the cap quickly. Fuel may
be under pressure and spray out of
the fuel filler neck especially in hot
weather, which may cause injury.
3. Remove the fuel filler cap by turning it
slowly counterclockwise.
4. Stop filling the tank after the fuel filler
pump automatically turns off. Do not add
any more fuel.
CAUTION
Make sure that the cap is tightened
until it clicks to prevent fuel spillage
in the event of an accident.
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 whiletightening.
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
. 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
lamp may come on. Refer to the“ Warning and indicator lights ”section
located in chapter 3.
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
comes on. Engine misfires as a
result of an empty tank could cause
damage to the engine.

7-8Starting and operating
not properly operating or there is one or
more diagnostic trouble codes stored invehicle ’s computer with the “CHECK
ENGINE ”warning light/MIL illuminated.
. 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. . 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.
