Fuel„Fuel requirementsT 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.
T 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 unleaded
gasoline.NOTEBe sure to use premium unleaded gas-
oline of 91 AKI or higher for a 2.5-liter
turbo engine model. If other gasoline
(lower than 91 AKI) is used, knocking, reduced output and poor accelerator
response will result.
T
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.
T 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.
T 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
problem is fuel related before returning
your vehicle to an authorized dealer for
service.
T
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 deter-
mined that the condition is caused by the
type of fuel used, repairs may not be cov-
ered by your warranty.
T Gasoline for cleaner air
Your use of gasoline with detergent addi-
tives will help prevent deposits from form-
Use of a fuel which is low in quality
or use of an inappropriate fuel addi-
tive may cause engine damage.

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).
T3 (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.
T 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.
T
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.
T 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.
mph (km/h)
NOTEIn order to prevent over-revving during
deceleration of the vehicle, the trans-
mission will remain in the current gear
if the speed of the vehicle is in excess
of the Maximum Allowable Speed for
the gear to which the selector lever has
been moved.T Driving tips
y Always apply the foot or parking brake
when the vehicle is stopped in the “D”, “3”,
“2”, “1” or “R” position.
y Always set the parking brake when

When shifting down a gear, ensure
that the vehicle is not travelling at a
speed exceeding the Maximum Al-
lowable Speed for the gear which is
about to be selected. Failure to ob-
serve this precaution can lead to en-
gine over-revving and this in turn
can result in engine damage.In addition, sudden application of
engine brakes when the vehicle is
travelling on a slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident in-
creased.

„ABS warning light1) U.S.-spec. models
2) Canada-spec. modelsThe ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.
NOTEIf the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal.
yThe warning light comes on right af-
ter the engine is started but goes out immediately, remaining off.
y
The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).
y The warning light comes on during
driving, but it goes out immediately
and remains off.

If the warning light behaves as fol-
lows, the ABS system may not be
working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.
yThe warning light does not come
on when the ignition switch is
turned to the “ON” position.
y The warning light comes on when
the ignition switch is turned to the
“ON” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12

y The warning light comes on dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.

Starting and operating
Electronic Brake Force Dis-
tribution (EBD) system (if equipped)The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS system and uses some of the ABS
system’s components to perform its func-
tion of optimizing the distribution of brak-
ing force. If any of the ABS components
used by the EBD function fails, the EBD
system also stops working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
„Steps to take if EBD system
fails1) U.S.-spec. models
2) Canada-spec. modelsIf a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light come on simultaneously.
The EBD system may be faulty if the brake
system warning light and ABS warning
light illuminate simultaneously during driv-
ing.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are ap-
plied harder than usual and the vehicle’s motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the system in-
spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.

Starting and operating
The following situations could indicate a
malfunction of the Vehicle Dynamics Con-
trol system; if any should occur, have an
authorized SUBARU dealer carry out an
inspection of the system at the first avail-
able opportunity.
yThe warning light does not turn on when
the ignition switch is turned to the ON po-
sition.
y The warning light turns on while the ve-
hicle is being driven.
y When a malfunction has occurred in the
Vehicle Dynamics Control electrical sys-
tem, only the warning light will turn on. In
such an event, the ABS will still be operat-
ing normally.
y The warning light will also turn on when
a problem occurs with the ABS or Vehicle
Dynamics Control electronic control sys-
tems.
Because the Vehicle Dynamics Control
system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical sys-
tem, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halts and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using normal braking. The Vehicle Dynamics
Control system and the ABS do not ad-
versely affect operation of the vehicle in
any way when they are inoperable; how-
ever should such a situation occur, drive
with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity.
NOTEWhen the warning light turns on and
off in the following way, it indicates
that the Vehicle Dynamics Control sys-
tem is operating normally.
y
Although turning on after the engine
has been started, the warning light
quickly turns off and stays off.
y The warning light turns on when the
vehicle is being driven; it then turns off
and stays off.
V Vehicle Dynamics Control OFF indi-
cator light
This light comes on to indicate that the Ve-
hicle Dynamics Control system is in non-
operation mode. This does not constitute
failure of the Vehicle Dynamics Control
system.NOTEy The indicator light may stay on for a
while after the engine has been started, especially in cold weather. This occurs
because the engine has not yet
warmed up and is completely normal.
The light will turn off when the engine
has reached a suitable operating tem-
perature.
y
When an engine problem occurs and
the malfunction indicator lamp turns
on, the indicator light will also come
on.
The following two situations could indicate
malfunction of the Vehicle Dynamics Con-
trol system; if either should occur, have an
authorized SUBARU dealer carry out an
inspection of that system at the first avail-
able opportunity.
y The indicator light does not turn on
when the ignition switch is turned to the
ON position.
y The indicator light fails to turn off after
the engine is started, even when several
minutes have passed to allow the engine
to heat up sufficiently.

T
Vehicle placard
The vehicle placard is affixed to the
driver’s side door pillar.
Example: The vehicle placard shows original
tire size, recommended cold tire infla-
tion pressure on each tire at maxi-
mum loaded vehicle weight, seating
capacity and loading information.
T
Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to rapidly
become hot. A sharp increase in tem-
perature could cause tread separa-
tion, and failure of the tire(s). Possible
resulting loss of vehicle control could
lead to an accident.
T
Measuring and adjusting air
pressure to achieve proper infla-
tion
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and be-
fore any long journey. Check the tire
pressures when the tires are cold.
Use a pressure gauge to adjust the
tire pressures to the specific values.
Driving even a short distance warms
up the tires and increases the tire
pressures. Also, the tire pressures are affected by the outside tempera-
ture. It is best to check tire pressure
outdoors before driving the vehicle.
When a tire becomes warm, the air in-
side it expands, causing the tire pres-
sure to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
