OnStar services require vehicle electrical system and
wireless service to be available and operating for fea-
tures to function properly. OnStar uses existing emer-
gency service providers as well as wireless and satel-
lite technologies.
In order to provide you with excellent service, calls
with the OnStar Center may be monitored or recorded. OnStar Service is: y available in the 48 contiguous United States, Alas-
ka, Hawaii; y available when the vehicle is within the operating
range of a cellular provider;y subject to limitations caused by atmospheric condi-
tions, such as severe weather or topographical condi-
tions, such as mountainous terrain; y subject to cellular carrier equipment limitations.
Global positioning locating capabilities will not be
available if satellite signals are obstructed. OnStar will not function if the vehicle’s battery is dis-
charged or disconnected. It may also be inoperative if
the vehicle is in an accident and the OnStar or vehicle
electrical system components are damaged.
OnStar is the communication link between you and ex-
isting governmental emergency and roadside service
providers. OnStar will receive your call and use rea-
sonable effort to contact an appropriate provider. On-
Star cannot promise that the providers will respond in
a timely manner or at all.
If metallic objects, including roof-mounted accessories
or metallic cargo within the accessory, are placed in
the immediate vicinity of the OnStar antenna, the an-
tenna’s performance will be degraded. This may pre-
vent the OnStar system from functioning properly.
Therefore, please use caution when installing roof-top

Use of a fuel which is low in quality or use of an
inappropriate fuel additive may cause engine

„ Fuel requirements
T 2.5 Liter models
The 2.5 Liter engine is designed to operate using un-
leaded gasoline with an octane rating of 87 AKI or
higher. T 3.0 Liter models
The 3.0 Liter engine is designed to operate using pre-
mium unleaded gasoline with an octane rating of 91
AKI or higher. Regular unleaded gasoline with an oc-
tane rating of 87 AKI may be used if necessary. For
optimum engine performance and driveability, it is rec-
ommended that you use premium grade unleaded
gasoline. T Fuel octane rating
This octane rating is the average of the Research Oc- tane and Motor Octane numbers and is commonly re-
ferred 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 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 filler pipe is designed to accept
only an unleaded gasoline filler nozzle. Under no cir-
cumstances 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 la-
bel. It is designed to optimize engine and emission
control system performance with gasoline that meets
the clean burning low-sulfur California gasoline speci-
fications. If you live in any other state than California,
your vehicle will operate on gasoline meeting Federal
specifications. Gasoline sold outside California is per-
mitted to have higher sulfur levels, which may affect
the performance of your vehicle’s catalytic converter

7-3

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 vehi-
cle 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, re-
pairs may not be covered by your warranty. TMMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may deteriorate and the CHECK
ENGINE warning light/Malfunction 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. T Gasoline for cleaner air
Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels containing alcohol may cause paint damage, which is not covered un-
der 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 continu-
ously 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 con-
tain no more than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
In addition, some gasoline suppliers are now produc-
ing reformulated gasolines, which are designed to re-
duce 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 detergents and oxygenates and if they have

7-4
Starting and operating
been reformulated to reduce vehicle emissions.
As additional guidance, only use fuels suited for your
vehicle as explained below. 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 sufficient
quantities of the proper cosolvents and corrosion in-
hibitors required to prevent damage to the fuel system.
Do not use fuel containing methanol EXCEPT under
these conditions.y If undesirable driveability problems are experienced
and you suspect they may be fuel related, try a differ-
ent brand of gasoline before seeking service at your
SUBARU dealer.y Fuel system damage or driveability problems which
result from the use of improper fuel are not covered
under the SUBARU Limited Warranty. „

yYou will see the “FUEL DOOR ” sign in the
combination meter. This indicates that the fuel fill-
er door (lid) is located on the right side of the ve-
hicle. 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” section located in
chapter 3.
y Never add any cleaning agents to the fuel
tank. The addition of a cleaning agent may
cause damage to the fuel system. y Make sure that the cap is tightened until it
clicks to prevent fuel spillage in the event of an
accident. 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. 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 emis-
sion control system might be damaged.
State emission testing (U.S. only)
Testing of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel dy-
namometer. Attempting to do so will result in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.
Resultant vehicle damage due to improper test-
ing is not covered under the SUBARU Limited
Warranty and is the responsibility of the state
inspection program or its contractors or licens-
ees.
At state inspection time, remember to tell your in-
spection or service station in advance not to place
your SUBARU AWD vehicle on a two-wheel dyna-
mometer. Otherwise, serious transmission dam-
age will result.
Some states have started using dynamometers in
their state inspection programs in order to meet their

in vehicle’s computer with the “ CHECK ENGINE”
warning light/MIL illuminated. y A state emission inspection may reject (not pass or
fail) a vehicle if the number of OBD system readinessmonitors “ Not Ready ” is greater than three. 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 adjust-
ments 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 the hood, trunk and rear gate are fully
closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and outside mir-rors.
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” po- sition.
9. Check the gauges, indicator and warning lights af-
ter starting the engine.
NOTE
Engine oil, engine coolant, brake fluid, washer flu-
id and other fluid levels should be checked daily,
weekly or at fuel stops.
