Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause damage to the
engine and/or fuel system.
&Fuel requirements
! Non-turbo models
The engine is designed to operate using
unleaded gasoline with an octane rating
of 87 AKI (90 RON) or higher .
! Turbo models
The engine is designed to operate at
maximum performance using unleaded
gasoline with an octane rating of 93 AKI
(98 RON) or higher . Unleaded gasoline
with an octane rating of 91 AKI (95 RON)
or higher may be used with no detriment to
engine durability or driveability. However,
you may notice a slight decrease in
maximum engine performance while using
91 AKI (95 RON) fuel.
Regular unleaded gasoline with an octane
rating of 87 AKI (90 RON) or higher may
also be used. Using regular unleaded gasoline will not be detrimental to engine
durability, nor will it affect your warranty
coverage. However, depending on your
driving habits and conditions, you may
notice a decrease in maximum engine
performance, fuel economy or slight en-
gine vibration or knocking. If you experi-
ence any of these conditions while using a
lower octane rated fuel, you may want to
return to using 91 AKI (95 RON) octane
rated fuel as soon as possible. Addition-
ally, if your vehicle knocks heavily or
persistently, or if you are driving with
heavy loads such as when towing a trailer,
the use of 91 AKI (95 RON) or higher
grade unleaded gasoline is required.
!
Fuel octane rating
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.
!RON
This octane rating is the Research Octane
Number. !
AKI
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).
! 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
Starting and operating/Fuel
–CONTINUED –7-3

Starting and operating/Fuel
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 light 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.
! Gasoline for cleaner air
Your use of gasoline with detergent
additives will help prevent deposits from
forming 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
materials called oxygenates. Use of these
fuels can also help keep the air cleaner. Oxygenated blend fuels, such as MTBE
(Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in
your vehicle, but should contain no more
than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from
any pump labeled E15, E30, E50 or E85
(which are only some examples of fuel
containing more than 10% ethanol).
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
operators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
.
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 ANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanol EXCEPT
under 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
improper fuel are not covered under the
SUBARU Limited Warranty.
CAUTION
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.

left. Do not remove the cap
quickly. Fuel may be under pres-
sure and spray out of the fuel
filler neck, especially in hot
weather. If you hear a hissing
sound while you are removing
the cap, wait for the sound to
stop and then slowly open the
cap to prevent fuel from spraying
out and creating a fire hazard.
3. Set the fuel filler cap on the cap holder
inside the fuel filler lid.
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 while
tightening.
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
light may illuminate. Refer to
“CHECK
ENGINE warning light/Malfunction in-
dicator light ”F 3-16.
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
7-6

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. Continuing to operate your
vehicle at an extremely low fuel
level may result in a reduction of
engine performance.State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.
CAUTION
. At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
. Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program or
its contractors or licensees.
California and a number of federal states have Inspection/Maintenance programs to
inspect your vehicle
’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’ s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’ s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspec-
tion of the OBDII system.
. The inspection of the OBDII system
consists of a visual operational check of
the “CHECK ENGINE ”warning light/mal-
function indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
. A vehicle
passes the OBDII system
inspection if proper operation of the
“ CHECK ENGINE ”warning light is ob-
served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before 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.
Starting and stopping the
engine (models without
push-button start system)
&Starting engine
CAUTION
Do not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.
NOTE
It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
controlled throttle ’s self-diagnosis
function. To overcome it, keep the
ignition switch in the “ON ”position
for approximately 10 seconds before
starting the engine. !
General precautions when starting
engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
. Do not start the engine near dry
foliage, paper, or other flam-
mable substances. The exhaust
pipe and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
. If the engine is stopped during
driving, the catalyst may over-
heat and burn.
