the direction of low frequencies to high fre-
quencies only.
Automatic tuning may not function proper-
ly if the station reception is weakened by
distance from the station or proximity to
tall buildings and hills.
Selecting preset stations
Presetting a station with a “Preset ” button
(7) allows you to select that station in a
single operation. Up to six AM, FM1 and
FM2 stations each may be preset.
How to preset stations
1. Press the “FM/AM ” selection button to
select AM, FM1 or FM2 reception.
2. Press the “SCAN ” button (5) or tune
the radio manually until the desired station
frequency is displayed.
3. Press one of the “Preset ” buttons (7)
for at least 1.5 seconds to store the fre-
quency. The frequency of the station will
flash once on the display at this time. If the
button is pressed for less than 1.5 sec-
onds, the preceding selection will remain
in memory.
NOTE
If the connection between the radio
and battery is broken for any reason
such as vehicle maintenance or radio
removal, all stations stored in the pre-
set buttons are cleared. If this occurs,
it is necessary to reset the preset but-
tons.
If a cell phone is placed near the ra-
dio, it may cause the radio to emit
noise when it receives calls. This noise
does not indicate a radio fault.

7-2 Starting and operating
Starting and operatingFuel
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.
WRX
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 unleaded
gasoline.
NOTE
Be sure to use premium unleaded gas-
oline of 91 AKI or higher for WRX. If
other gasoline (lower than 91 AKI) is
used, knocking, reduced output and poor accelerator response will result.
WRX-STI
The 2.5-liter turbo engine is designed to
operate using super-premium unleaded
gasoline with an octane rating of 93 AKI or
higher. If super-premium unleaded gaso-
line with an octane rating of 93 AKI or
higher is not available, premium unleaded
gasoline with an octane rating of 91 AKI or
higher may be temporarily used. For opti-
mum engine performance and driveability,
it is required that you use super-premium
grade unleaded gasoline with an octane
rating of 93 AKI or higher.
NOTE
Be sure to use super-premium unlead-
ed gasoline of 93 AKI or higher for
WRX-STI. If other gasoline (lower than
93 AKI) is used, knocking, reduced out-
put and poor accelerator response will
result.
Fuel octane rating
This octane rating is the average of the
Research Octane and Motor Octane num-
bers and is commonly referred to as the
Anti Knock Index (AKI).
Using a gasoline with a lower octane rat-
ing 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.
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
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 Califor-
nia gasoline specifications. If you live in
any other state than California, your vehi-
cle will operate on gasoline meeting Fed-
eral specifications. Gasoline sold outside
California is permitted to have higher sul-
fur levels, which may affect the perfor-
mance of your vehicle ’s catalytic convert-
er 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
Use of a fuel which is low in quality
or use of an inappropriate fuel addi-
tive may cause engine damage.

Manual transmission – 5
speeds (except WRX-STI)
The manual transmission is a fully syn-
chromeshed, 5-forward-speed and 1-re-
verse-speed transmission.
The shift pattern is shown on the shift le-
ver knob. When shifting from 5th gear to
reverse gear, first return the shift lever to
the neutral position then shift into reverse
gear.
To change gears, fully depress the clutch
pedal, move the shift lever, and gradually
let up on the clutch pedal.
If it is difficult to shift into gear, put the
transmission in neutral, release the clutch
pedal momentarily, and then try again.
Shifting speeds
Recommended shifting speeds
The best compromise between fuel econ-
omy and vehicle performance during nor-
mal driving is ensured by shifting up at the
speeds listed in the following table.
Maximum allowable speeds
The following table shows the maximum
speeds that are possible with each differ-
ent gear.
Never exceed the speed limit listed in the
following table for each gear position ex-
cept for brief acceleration in an emergen-
cy. The tachometer ’s needle will enter the
red area if these speeds are exceeded.
Failure to observe this precaution can
lead to excessive engine wear and poor
fuel economy.

Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral posi-
tion. Engine braking has no effect in
either of these conditions and the
risk of an accident is consequently
increased.
Shift into reverse ONLY when the
vehicle has completely stopped. It
may cause damage to the transmis-
sion to try shifting into reverse
when the vehicle is moving.

Starting and operating 7-15
Turn the dial rearward to reduce the initial
LSD torque; when the white line reaches
the rearmost position, the initial LSD
torque will be minimum and the “ ” indi-
cator light will come on. Under this condi-
tion, only the Mechanical LSD torque will
limit the differential action.
NOTE
A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. If you become stuck in
snow or mud, turning the center differ-
ential control dial to the frontmost po-
sition will help move the vehicle out.
(The “LOCK ” indicator will come on at
the frontmost position.)
During cornering or when making
turns (especially when getting into the
garage), the rotational difference be-
tween the front and rear wheels may
cause a braking effect accompanied by vibration and noise. This does not indi-
cate a problem. The phenomenon will
disappear when you turn the center dif-
ferential control dial to the rearmost
position (minimum initial LSD torque
position).
Use the center-differential indicator
light only as a rough indication of the
initial LSD torque.
If you operate the center differential
control dial while quickly accelerating
or turning a tight corner, you may feel
slight shocks. This is due to differential
action by the center differential and
does not indicate a problem.
Temporary release
When the driver stops the vehicle and
pulls the parking-brake lever after manual-
ly setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator in the combination meter
continues to show the driver ’s selected ini-
tial LSD torque. When the driver releases
the parking-brake lever, the initial LSD
torque set by the driver is restored.
Do not turn the control dial when
a wheel slippage occurs. Wait un-
til the wheelspin has been
brought under control.

Under any of the following condi-
tions, turn the center differential
control dial to the rearmost posi-
tion to minimize the initial LSD
torque:

7-18 Starting and operating
the original gear position.
While climbing a grade
When driving up hill, undesired upshift to
4th gear is prevented from taking place
when the accelerator pedal is released.
This minimizes the chances of subse-
quent downshifting to a lower gear when
accelerating again. This prevents repeat-
ed upshifting and downshifting resulting in
a smoother operation of the vehicle.
NOTE
The transmission may downshift to
2nd or 1st gear, depending on the way
the accelerator pedal is pressed to ac-
celerate the vehicle again.
While going down a hill
When descending a steep hill, depressing
the brake pedal will cause the transmis-
sion to downshift to 3rd gear, thus apply-
ing engine braking. Reacceleration for a
short time will cause the transmission to
upshift normally.
NOTE
In some cases, depressing the brake
pedal on a downhill grade does not re-
sult in an automatic downshift to 3rd
gear. This can happen when the auto-
matic transmission fluid temperature is
very low, for example, during driving shortly after the vehicle has been
parked for an extended period of time.
When the ATF temperature has risen to
a certain level, automatic downshift
normally takes place. In the meantime,
downshift manually for engine braking
as required.
Also, downshifting when braking
downhill will not occur at speeds
above approximately 48 mph (78 km/h).
3 (Third)
This position is for using engine braking
when going down a hill or for climbing a
grade.
The transmission automatically shifts into
a suitable gear from 1st to 3rd according
to the vehicle speed and the acceleration
you require.
When more acceleration is required in this
position, press the accelerator pedal fully
to the floor and hold that position. The
transmission will automatically downshift
to 2nd or 1st gear. When you release the
pedal, the transmission will return to the
original gear position.
2 (Second)
This position is for using engine braking
when going down a hill or for climbing a
steep grade.
In this position, the transmission holds in the 2nd gear.
Use this position when starting off from a
standstill on slippery road surfaces such
as mud or snow. It will ensure greater trac-
tion.
1 (First)
This position is for driving up or down very
steep grades, or driving through mud or
sand, or on slippery surfaces. In this posi-
tion, the transmission holds in the 1st
gear.
Maximum speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When shifting down a gear, it is important
to confirm that the current vehicle speed is
not in excess of the Maximum Allowable
Speed of the gear which is about to be se-
lected.
