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 Â’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.

6-8 Interior equipment
If the socket has been used for electrical
appliances, damage may have been done
to the internal mechanism that causes a
cigarette lighter to “pop out ” after its ele-
ment has been heated. For that reason, a
cigarette lighter, even if it is a genuine
part, should not be used in the socket. If
you want to use the socket for a cigarette
lighter again, or to protect your purchaser
before you sell your vehicle, have your
SUBARU dealer replace the socket with a
new one.
Ashtray
To open the ashtray, push lightly on the lid
below the climate controls.
Fully close the lid after using it to help re-
duce residual smoke.
To remove the ashtray for cleaning, hold
the right and left sides of the ashtray and
pull it out.
NOTE
Particles of ash and tobacco will accu-
mulate around the hinges of the ash-
tray Â’s inner lid. Clean them off using a
toothbrush or other narrow-ended im-
plement.
If the plug on your electric appli-
ance is either too loose or too
tight for the socket, this can result
in a poor contact or cause the
plug to get stuck. Only use plugs
that fit properly.
Use of an electric appliance in the
socket for a long period of time
while the engine is not running
can cause battery discharge.
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.
600222
Do not use ashtrays as waste recep-
tacles or leave a lighted cigarette in
an ashtray. This could cause a fire.

door release.
The floor mat is secured using the built-in
grommet, by placing the grommet over the
pin and pushing downward.
Coat hook
The coat hook is attached to the rear left
passenger Â’s hand grip.
600513
Make sure the driver Â’s floor mat is
placed back in its proper location
and correctly secured on its retain-
ing pin. If the floor mat slips forward
and interferes with the movement of
the pedals during driving, it could
cause an accident.
600481
Never hang anything on the coat
hook that might obstruct the driv-
er Â’s view or that could cause injury
in sudden stops or in a collision.
And do not hang items on the coat
hook that weigh 2.2 lbs (1 kg) or
more.

tents from direct sunlight. This cover is de-
tachable to make room for additional car-
go.
Using the cover
To extend the cover, pull the end of the
cover out of the housing, then insert its
hooks into the catches as shown. To re-
wind it, unhook it from the catches and it
will rewind automatically. You should hold
on to the cover and guide it back into the
cover housing while it is rewinding.
To remove the cover
1. Rewind the cover. 2. Pull either sleeve on the end of the cov-
er housing to shorten the cover
Â’s length.
3. Take it off the retainer.
Stowage of the cover
600225
Do not place anything on the ex-
tended cover. Putting excessive
weight on the extended cover can
break it and an object on the cover
could tumble forward in the event of
a sudden stop or collision. This
could cause serious injury.
Be careful not to scratch the rear
gate stays while extending and re-
winding the cover.
Scratches on the stays could cause
leakage of gas from the stays, which
may result in their inability to hold
the rear gate open.

er housing to shorten the cover Â’s length.
2. Insert the projections located on the
both ends of the sleeve into the recesses
of the retainers.
Cargo tie-down hooks (Wag-
on – if equipped)
The cargo area is equipped with four tie-
down hooks so that cargo can be secured
with a cargo net or ropes.
When using the tie-down hooks, turn them
down out of the storing recesses. When
not in use, put the hooks up into the stor-
ing recesses.
600228

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 Â’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 Â’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.

problem is fuel related before returning
your vehicle to an authorized dealer for
service.
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.
Gasoline for cleaner air
Your use of gasoline with detergent addi-
tives will help prevent deposits from form-
ing in your engine and fuel system. This
helps keep your engine in tune and your
emission control system working properly,
and is a way of doing your part for cleaner
air. If you continuously use a high quality
fuel with the proper detergent and other
additives, you should never need to add
any fuel system cleaning agents to your
fuel tank.
Many gasolines are now blended with ma-
terials called oxygenates. Use of these fu- els can also help keep the air cleaner. Ox-
ygenated blend fuels, such as MTBE (Me-
thyl Tertiary Butyl ether) or ethanol (ethyl
or grain alcohol) may be used in your ve-
hicle, but should contain no more than
15% MTBE or 10% ethanol for the proper
operation of your SUBARU.
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station oper-
ators if their gasolines contain detergents
and oxygenates and if they have been re-
formulated to reduce vehicle emissions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following.
Fuel should be unleaded and have an
octane rating no lower than that specified
in this manual.
Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLY if it does not exceed 5% of the fuel
mixture AND if it is accompanied by suffi-
cient quantities of the proper cosolvents
and corrosion inhibitors required to pre- vent damage to the fuel system. Do not
use fuel containing methanol
EXCEPT un-
der these conditions.
If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
Fuel system damage or driveability
problems which result from the use of im-
proper fuel are not covered under the
SUBARU Limited Warranty.
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty.
