The low fuel warning light illuminates
when the tank is nearly empty approxi-
mately 2.6 US gal (10.0 liters, or 2.2 Imp
gal). It only operates when the ignition
switch is in the “ON ”position. When this
light illuminates, fill the fuel tank immedi-
ately. NOTE
This light does not turn off unless the
tank is replenished up to an internal
fuel quantity of approximately 3.7 US
gal (14 liters, 3.1 Imp gal).
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
illuminates. Engine misfires as a
result of an empty tank could cause
damage to the engine. &
Hill start assist warning
light (MT models)
When the ignition switch is in the “ON ”
position, the Hill start assist warning light
illuminates and turns off after approxi-
mately 2 seconds. While the engine is
rotating, if there are any malfunctions, the
light will illuminate.
WARNING
When the Hill start assist system
light illuminates, have the vehicle
inspected at an authorized SUBARU
dealer.
& Door open warning light
The door open warning light illuminates if
any door or the rear gate is not fullyclosed.
Always make sure this light is out before
you start to drive. &All-Wheel Drive warn-
ing light (AT models)
The All-Wheel Drive warning light illumi-
nates when the ignition switch is turned tothe “ON ”position and turns off after the engine has started.
This light illuminates when All-Wheel
Drive is disengaged and the drive me-
chanism is switched to Front Wheel Drive
for maintenance or similar purposes.
It flashes if the vehicle is driven with tires
of differing diameters fitted on the wheels
or with an excessively low air pressure in
any of the tires.
CAUTION
Continuing to drive with the AWD
warning light flashing can damage
the powertrain. If the AWD warning
light starts to flash, promptly park in
a safe place and check whether the
tires have differing diameters and
whether any of the tires has an
excessively low inflation pressure.
& Automatic headlight
beam leveler warning
light (models with HID headlights)
The automatic headlight beam leveler
warning light illuminates when the ignition
switch is turned to the “ON ”position and
turns off after approximately 3 seconds.
This light illuminates when the automatic
headlight beam leveler does not operate

normally.
If this light illuminates while driving or does
not turn off approximately 3 seconds after
turning the ignition switch to the“ON ”
position, have your vehicle inspected at
your SUBARU dealer. & Vehicle Dynamics
Control operation indi-
cator light
This light illuminates when the ignition
switch is ON and turns off approximately 2
seconds later.
It blinks when the skid suppression func-
tion is activated. It illuminates when only
the traction control function is operating.
The Vehicle Dynamics Control system is
probably malfunctioning under any of the
following conditions. Have your vehicle
checked at a SUBARU dealer immedi-
ately. .The light does not illuminate when the
ignition switch is turned to the “ON ”
position.. The light does not turn off even after a
period of approximately 2 seconds after
the ignition switch has been turned to the“ ON ”position. &
Vehicle Dynamics
Control warning light/
Vehicle Dynamics Con-
trol OFF indicator light
This warning light has both the function of
indicating malfunctions in the Vehicle
Dynamics Control system and the function
of indicating that the Vehicle Dynamics
Control system has been deactivated.
It illuminates in the event of a malfunction
in the system and is on when the system
is not operating.
This warning light illuminates when the
ignition switch is turned to the “ON ”
position and turns off several seconds
after the engine has started. It indicates
that the Vehicle Dynamics Control system
is in normal operation. ! Vehicle Dynamics Control warning light
The Vehicle Dynamics Control system is
probably inoperative under any of the
following conditions. Have your vehicle
checked at a SUBARU dealer immedi-
ately. . The warning light does not illuminate
when the ignition switch is turned to the “ ON ”position.
. The warning light illuminates while the
vehicle is running. .
If the electrical circuit of the Vehicle
Dynamics Control system itself becomes
faulty, the warning light only illuminates. At
this time, the ABS (Anti-lock Brake Sys-
tem) remains fully operational. . The warning light illuminates when the
electronic control system of the ABS/
Vehicle Dynamics Control system mal-functions.
The Vehicle Dynamics Control system
provides its ABS control through the
electrical circuit of the ABS system.
Accordingly, if the ABS is inoperative, the
Vehicle Dynamics Control system be-
comes unable to provide ABS control. As
a result, the Vehicle Dynamics Control
system also becomes inoperative, caus-
ing the warning light to illuminate. Though
both the Vehicle Dynamics Control and
ABS systems are inoperative in this case,
the ordinary functions of the brake system
are still available. You will be safe while
driving with this condition, but have your
vehicle checked at a SUBARU dealer as
soon as possible.
NOTE
If the warning light behavior is as
described below, the Vehicle Dynamics
Control system may be considerednormal. . The warning light illuminates right Instruments and controls

vehicle is subsequently being driven.. The warning light illuminates during
driving, but it turns off immediately and
remains off. ! Vehicle Dynamics Control OFF in-
dicator light
. It illuminates when the Vehicle Dy-
namics Control OFF switch is pressed. . It also illuminates when the Vehicle
Dynamics Control system is deactivated. NOTE . The light may remain on for a while
after the engine has been started,
especially in cold weather. This does
not indicate the existence of a problem.
The light should turn off as soon as the
engine has warmed up.. The indicator light illuminates when
the engine has developed a problem
and the CHECK ENGINE warning light/
malfunction indicator lamp is on.
The Vehicle Dynamics Control system is
probably faulty under the following condi-
tion. Have your vehicle checked at a
SUBARU dealer as soon as possible. . The light does not turn off even after the lapse of several minutes (the engine
has warmed up) after the engine hasstarted. &
Security indicator light
The security indicator light deters potential
thieves by indicating that the vehicle is
equipped with an immobilizer system. It
begins flashing (approximately once every
3 seconds) approximately 60 seconds
after the ignition switch is turned from the“ON ”position to the “Acc ”or “LOCK ”
position or immediately after the key is
pulled out.
If the security indicator light does not flash,
the immobilizer system may not be func-
tioning properly. If this occurs, contact
your SUBARU dealer as soon as possible. In case an unauthorized key is used (e.g.,
an imitation key), the security indicator
light illuminates. NOTE
Even if the security indicator light
flashes irregularly or its fuse blows
(the light does not flash if its fuse is
blown), the immobilizer system will
function normally. &
SPORT mode indicator
light (AT models)
This light illuminates when the ignition
switch is turned to the “ON ”position and
turns off after the engine has started.
When the select lever is moved to the
manual gate, the SPORT mode is se-
lected and the indicator light illuminates.

Operating tips for heater and
air conditioner &Cleaning ventilation grille
Always keep the front ventilation inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept clean
because cooling performance is impaired
by any accumulation of insects and leaves
on the condenser. &Efficient cooling after parking
in direct sunlight
After parking in direct sunlight, drive with
the windows open for a few minutes to
allow outside air to circulate into the heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency.
& Lubrication oil circulation in
the refrigerant circuit
Operate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil. & Checking air conditioning
system before summer sea-son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer. & Cooling and dehumidifying in
high humidity and low tem-
perature weather conditions
Under certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate
any problem with the air conditioning system. &
Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steepupgrade. & Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od of adding, changing or checking the
refrigerant is different from the method for
CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty.

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 2.5-liter non-turbo engine is designed
to operate using unleaded gasoline with
an octane rating of 87 AKI or higher.
! Turbo models
The 2.5-liter turbo engine is designed to
operate using premium unleaded gaso-
line with an octane rating of 91 AKI or
higher . If premium unleaded gasoline is
not available, 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
gasoline of 91 AKI or higher for turbo
engine models. If other gasoline (lower than 91 AKI) is used, knocking, re-
duced output and poor accelerator
response will result. !
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. ! 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
determined that the condition is caused
by the type of fuel used, repairs may not
be covered by your warranty.

WARNING
. When refueling, insert the fuel
nozzle securely into the fuel filler
pipe. If the nozzle is lifted or not
fully inserted, its automatic stop-
ping mechanism may not func-
tion, causing fuel to overflow the
tank and creating a fire hazard.
. Stop refueling when the auto-
matic stop mechanism on the
fuel nozzle activates. If you con-
tinue to add fuel, temperature
changes or other conditions
may cause fuel to overflow from
the tank and create a fire hazard.
4. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
5. Put the cap back on, turn it clockwise
until you hear a clicking noise. Be certain
not to catch the tether under the cap whiletightening.
6. Close the fuel filler lid completely.
If you spill any fuel on the painted surface,
rinse it off immediately. Otherwise, the
painted surface could be damaged. NOTE .
You will see the “”sign in the fuel
gauge. This indicates that the fuel filler
door (lid) is located on the right side of
the vehicle.. 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/malfunction indicator
lamp may illuminate. Refer to “CHECK
ENGINE warning light/Malfunction in-
dicator lamp ”F 3-12.
CAUTION
. Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
. After refueling, turn the cap to the
right until it clicks to ensure that
it is fully tightened. If the cap is
not securely tightened, fuel may
leak out while the vehicle is being
driven or fuel spillage could
occur in the event of an accident,
creating a fire hazard.
. 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.
. 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 emission control system
may be damaged. It could also
lead to fuel spillage and a fire.
. Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank
could cause damage to the en-gine. Starting and operating
