6-6 Interior equipment
Cigarette lighter socket
A cigarette lighter socket can be found be-
hind the ashtray lid under the climate con-
trols. Push gently on the lid to open it. A
cigarette lighter plug is an optional acces-
sory. It is available from your SUBARU
dealer.
The cigarette lighter socket may also be
used as a power source for an in-car use
electrical appliance.
Do not place any foreign objects,
especially metal ones such as
coins or aluminum foil, into the
accessory power outlet. That
could cause a short circuit. Al-
ways put the cap on the accesso-
ry power outlet when it is not in
use.
Use only electrical appliances
which are designed for 12V DC
and which consume less than
120W. Overloading the accessory
power outlet can cause a short
circuit. Do not use double adapt-
ers or more than one electrical ap-
pliance.
If the plug on your electric appli-
ance is either too loose or too
tight for the accessory power out-
let, this can result in a poor con-
tact or cause the plug to get stuck.
Only use plugs that fit properly.
Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause battery dis-
charge.
Before driving your vehicle, make
sure that the plug and the cord on
your electrical appliance will not
interfere with your shifting gears
and operating the accelerator and
brake pedals. If they do, do not
use the electrical appliance while
driving.

Use with a cigarette lighter
The cigarette lighter operates only when
the ignition switch is in the “ON ” and
“ ACC ” positions.
To use the cigarette lighter, push in the
knob and wait a few moments. It will auto-
matically spring up when ready for use.
Using as an accessory power
outlet
Electrical power (12V DC) from the battery
is available at the socket when the ignition
switch is either in the “ACC ” or “ON ” posi-
tion.
If you use the socket as an accessory
power outlet, take the following precau-
tions.
When the socket is not in use, always put
the cap on the socket to prevent any for-
eign object from entering it.
The electrical power outlet locat-
ed on the lower part of the instru-
ment panel is originally designed
to use a genuine SUBARU ciga-
rette lighter plug. Do not use non-
genuine cigarette lighter plugs in
the socket. Doing so may cause a
short-circuit and overheating, re-
sulting in a fire.
If the socket is ever used for a
plug-in accessory such as a mo-
bile phone, that may damage the
portion of the socket ’s internal
mechanism that causes a ciga-
rette lighter plug to “pop out ” af-
ter its lighter element is heated.
Therefore, do not place a cigarette
lighter plug in a socket that has
been used, even once, to power a
plug-in accessory. Doing so may
cause the plug to stick and over-
heat, creating a potential fire haz-
ard.
Do not place any foreign objects,
especially metal ones such as
coins or aluminum foil, into the
socket. That could cause a short
circuit.
To avoid being burned, never grasp
the lighter by the end with the heat-
ing element. Doing so could result
in injury and could also damage the
heating element.
600526
Do not hold the lighter pushed in,
because it will overheat.
Use only in-car use electrical ap-
pliances which are designed for
12V DC and which consume less
than 120W. Overloading the sock-
et can cause a short circuit. Do
not use double adapters or more
than one electrical appliance.

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.

lease lever up. The lever is on the floor at
the left of the driver ’s seat.
1) Open
2) Close
2. Remove the fuel filler cap by turning it
slowly counterclockwise.
3. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
4. Put the cap back on, turn it clockwise
until you hear a clicking noise. Be certain
not to catch the tether under the cap while
tightening.
5. 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 “ ” or “FUEL
DOOR ” 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 may come on. Refer to
the “Warning and indicator lights ” sec-
tion located in chapter 3.

When opening the cap, do not re-
move the cap quickly. Fuel may be
under pressure and spray out of
the fuel filler neck especially in
hot weather, which may cause in-
jury.

7-6 Starting and operating
The EPA has issued regulations for in-
specting the On-Board Diagnostic (OBD)
system as part of the state emissions in-
spection. The OBD system is designed to
detect engine and transmission problems
that might cause vehicle emissions to ex-
ceed allowable limits. These inspections
apply to all 1996 model year and newer
passenger cars and light trucks. Over 30
states plus the District of Columbia have
implemented the OBD system inspection.
The inspection of the OBD system con-
sists of a visual operational check of the “ CHECK ENGINE ” warning light/malfunc-
tion indicator lamp (MIL) and an examina-
tion of the OBD system with an electronic
scan tool while the engine is running.
A vehicle passes the OBD system in-
spection if proper the “CHECK ENGINE ”
warning light/MIL illumination is observed,
there is no stored diagnostic trouble
codes, and the OBD system readiness
monitors are complete.
A vehicle fails the OBD inspection if the
“ CHECK ENGINE ” warning light/MIL is
not properly operating or there is one or
more diagnostic trouble codes stored in
vehicle ’s computer with the “CHECK EN-
GINE ” warning light/MIL illuminated.
A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBD system readiness monitors “Not
Ready ” is greater than one. Under this
condition, the vehicle operator should be
instructed to drive his/her vehicle for a few
days to set the monitors and return for an
emission re-inspection.
Owners of rejected or failing vehicles
should contact their Subaru Dealer for
service.
Preparing to drive
You 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 infla-
tion.
3. Look under the vehicle for any sign of
leaks.
4. Check that the hood, trunk (Sedan)
and rear gate (Wagon) 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.
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Resultant vehicle damage due to im-
proper testing is not covered under
the SUBARU Limited Warranty and
is the responsibility of the state in-
spection program or its contractors
or licensees.

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.
700358
Under any of the following condi-
tions, turn the center differential
control dial to the rearmost posi-
tion to minimize the initial LSD
torque:
When a temporary spare tire is
installed
When your vehicle is towed
When the vehicle is stopped
with the manual mode selected
