RADIO (1-800-967-2346). & Sirius satellite radio
Sirius satellite radio is a recent innovation
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.com or call 1-888-539-SIRIUS
(7474) for more information. Sirius, the
Sirius dog logo, channel names and logos

Satellite 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. !
XMTMsatellite radio reception tips
for antenna on the windshield (for
U.S.A. only —if equipped)
For some models, the satellite radio
antenna is fixed to the upper right hand
corner of the windshield.
The XM
TMsatellite radio receiver that is
fitted to your vehicle receives the neces-
sary signals from two specially designated
satellites that are in a geostationary 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 line of sight Audio

Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.
& Fuel requirements
! Non-turbo models
The engine is designed to operate using
unleaded gasoline with an octane rating
of 87 AKI (90 RON) or higher .
! Turbo models
! Except STI
The engine is designed to operate usingpremium 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. NOTE
Be 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 willresult. !
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 forservice. Starting and operating
