that allows the listener to experience
digital sound quality and to have a greater
variety of channels.
Use of satellite radio (Sirius) requires a
tuner, antenna and a service contract. For
details, please contact your SUBARU dealer or visit Sirius Satellite Radio at
www.sirius.ca or call 1-888-539-7474 for
more information. Sirius, the Sirius dog

Satellite radio receptionSatellite radio signals are best received in
areas with a clear view of the open sky. In
areas where there are tall buildings, trees,
tunnels or other structures that may
obstruct the signal of the satellites, there
may be signal interruptions. Other circum-
stances that may result in signal loss
include driving near a wall, steep cliff, hill
or driving on the lower level of a multi-
tiered road or inside of a parking garage.
To help reduce this condition, satellite
radio providers have installed ground-
based repeaters in heavily populated
areas. However, you may still experience
reception problems in some areas. !

satellite radio receiver
that is fitted to your vehicle receives the
necessary signals from two specially
designated satellites that are in a geosta-
tionary orbit over the equator. One satellite
covers the east coast and the other covers
the west coast. Both of them direct their
signals north. These signals are then
relayed throughout the radio reception
area by a network of ground repeater
stations. The satellite radio signals are
transmitted as “line of sight”signals. The

Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.& Fuel requirements! Except STI
The engine is designed to operate using
premium unleaded gasoline with an
octane rating of 91 AKI (95 RON) or
higher . If premium unleaded gasoline is
not available, regular unleaded gasoline
with an octane rating of 87 AKI (90 RON)
or higher may be temporarily used. For
optimum engine performance and drive-
ability, it is required that you use premium
grade unleaded gasoline.NOTEBe sure to use premium unleaded
gasoline of 91 AKI (95 RON) or higher.
If other gasoline (lower than 91 AKI (95
RON)) is used, knocking, reduced out-
put and poor accelerator response will
result. !
STI
The engine is designed to operate at
maximum performance using unleaded
gasoline with an octane rating of 93 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.
! 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. Contact
your SUBARU dealer 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.
!
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-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 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
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 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 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.
CAUTION
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.&
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.

whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank
could cause damage to the en-
gine.
State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled 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 or
its 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 inspec-
tion 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
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 ob-
served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.Starting and operating

Starting and operating
. 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 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 put
on 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 for
state emission testing.
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 the hood, trunk (4-door)
and rear gate (5-door) 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.

Starting and operating
Stopping the engineThe ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
WARNING
Do not stop the engine when the
vehicle is moving. This will cause
loss of power to the power steering
and the brake booster, making steer-
ing and braking more difficult. It
could also result in accidental acti-
vation of the “LOCK ”position on the
ignition switch, causing the steering
wheel to lock.
Remote engine start system
(dealer option)
WARNING
. Do not start the engine using the
remote start system in an en-
closed environment (e.g., in a
closed garage). Prolonged opera-
tion of a motor vehicle in an
enclosed environment can cause
a harmful build-up of Carbon
Monoxide. Carbon Monoxide is
harmful to your health. Exposure
to high levels of Carbon Monox-
ide can cause headaches, dizzi-
ness or in extreme cases uncon-
sciousness and/or death.
. Before performing any servicing
of the vehicle, temporarily place
the remote engine start system in
service mode to prevent the
system from unexpectedly start-
ing the engine.
& Starting your vehicleThe remote engine start system is acti-
vated by pressing the “
”button twice
within 3 seconds on your remote engine
start transmitter. The system will check
certain pre-conditions before starting, and
if all safety parameters are correct, the
engine will start within 5 seconds. While
the vehicle is operating via remote engine
start, the vehicle ’s power window features
will be disabled. Also, the system has a
timer and will shut down after 15 minutes if
you do not operate the vehicle. Press and
hold the “
”button for 2 seconds again to
turn the vehicle off. If the vehicle’ s starter
cranks but does not start or starts and
stalls, the remote engine start system will
power off then attempt to start the vehicle
