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.

2) Close2. 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
yYou 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.
y 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.
(Turbo model only) Promptly put fuel in
the tank whenever the low fuel warning
light comes on. Engine misfires as a re-
sult of an empty tank could cause dam-
age to the engine.
y Gasoline vapor is highly flamma-
ble. Before refueling, always first
stop the engine and make sure
that there are no lighted ciga-
rettes, open flames or electrical
sparks in the adjacent area.

y
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.
300121
yNever add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause dam-
age to the fuel system.
y Make sure that the cap is tight-
ened until it clicks to prevent fuel
spillage in the event of an acci-
dent.
y Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels may
cause paint damage, which is not
covered under the SUBARU Limit-
ed Warranty.

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.
yThe 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
y 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. y
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.
y 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.
y Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Preparing to driveYou 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 and rear gate 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.NOTEEngine 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.

Stopping the engineThe ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
If you restart the engine while the
vehicle is moving, shift the selector
lever into the “N” position. Do not
attempt to place the selector lever of
a moving vehicle into the “P” posi-
tion.
Do not stop the engine when the ve-
hicle is moving. This will cause loss
of power to the power steering and
the brake booster, making steering
and braking more difficult. It could
also result in accidental activation
of the “LOCK” position on the igni-
tion switch, causing the steering
wheel to lock.

Starting and operating
„Disc brake pad wear warning
indicatorsThe disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, imme-
diately have your vehicle checked by your
SUBARU dealer.
ABS (Anti-lock Brake Sys-tem)The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. This helps prevent the loss of steering
control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h).
„ABS system self-checkYou may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition.
700040
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident.
yThe ABS system does not always
decrease stopping distance. You
should always maintain a safe fol-
lowing distance from other vehi-
cles.
y When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be longer
for a vehicle with the ABS system
than one without. When driving
under these conditions, therefore,
reduce your speed and leave am-
ple distance from other vehicles.
y When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the op-
eration of the ABS system.

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
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system ad-
justs the engine’s output and the wheels’
respective braking forces to help maintain
traction and directional control.
yTraction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dynam-
ics Control operation indicator light.
y Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
NOTEy
Slight twitching of the brake pedal
may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.
y When driving off immediately after
starting the engine, a short-lived oper-
ation noise may be noticed coming
from the engine compartment. This
noise is generated as a result of a
check being performed on the Vehicle
Dynamics Control system and is nor-
mal.
y Depending on the timing of activa-
tion of the brakes, certain situations
may occur just after driving off where
the brake pedal seems to exhibit a jolt-
ing motion. This too is a consequence
of the Vehicle Dynamics Control opera-
tional check and is normal.
y In the circumstances listed in the fol-
lowing, the vehicle may be more unsta- ble than it feels to the driver. The Vehi-
cle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault.
y on gravel-covered or rutted roads
y on unfinished roads
y when the vehicle is towing a trailer
y when the vehicle is fitted with
snow tires or winter tires
y Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly dif-
ferent compared to that for normal con-
ditions.
y Even if the vehicle is equipped with a
Vehicle Dynamics Control system, it is
important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand).
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the ve-
hicle in such a condition.
y It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with Ve-
hicle Dynamics Control.
– Keep the tire pressure at the
proper level as shown on the
placard attached to the vehi-
cle’s door pillar.
– Use only the special temporary spare tire to replace a flat tire.
With a temporary spare tire, the
effectiveness of the Vehicle Dy-
namics Control system is re-
duced and this should be taken
into account when driving the
vehicle in such a condition.

Driving tips
Off road drivingBecause of the AWD feature and higher
ground clearance, your SUBARU can be
driven on ordinary roads or off-road. But
please keep in mind that an AWD
SUBARU is a passenger car and is nei-
ther a conventional off-road vehicle nor an
all-terrain vehicle. If you do take your
SUBARU off-road, certain common sense
precautions such as the following should
be taken:
yMake certain that you and all of your
passengers are wearing seatbelts.
y Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
y Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
y Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and the
like.
y Do not drive across steep slopes. In-
stead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or down slopes that are too steep.
y
Avoid sharp turning maneuvers, espe-
cially at higher speeds.
y Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead drive
with your fingers and thumbs on the out-
side of the rim.
y If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and completely through the stream. The
water should be shallow enough that it
does not reach the vehicle’s undercar-
riage. Water entering the engine air intake
or the exhaust pipe or water splashing
onto electrical parts may damage your ve-
hicle and may cause it to stall. Never at-
tempt to drive through rushing water; re-
gardless of its depth, it can wash away the
ground from under your tires, resulting in
possible loss of traction and even vehicle
rollover.
y Always check your brakes for effective-
ness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
y Do not drive or park over or near flam- mable materials such as dry grass or fall-
en leaves, as they may burn easily. The
exhaust system is very hot while the en-
gine is running and right after the engine
stops. This could create a fire hazard.
y
After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur.
y Secure all cargo carried inside the vehi-
cle and make certain that it is not piled
higher than the seatbacks. During sudden
stops or jolts, unsecured cargo could be
thrown around in the vehicle and cause in-
jury. Do not pile heavy loads on the roof.
Those loads raise the vehicle’s center of
gravity and make it more prone to tip over.
y If you must rock the vehicle to free it
from sand or mud, depress the accelera-
tor pedal slightly and move the selector le-
ver back and forth between “D” and “R” re-
peatedly. Do not race the engine. For the
best possible traction, avoid spinning the
wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission

Make sure that all the tires on your vehicle
are properly inflated to the pressure spec-
ified on the tire placard located on the driv-
er’s side center pillar.
Trailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer manufacturer’s
specifications.„ Trailer towing tips
T Before starting out on a trip
y Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer.
y Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable.
y Check that the tire pressures are cor-
rect.
y Check that the vehicle and trailer are
connected properly. Confirm that – the trailer tongue is connected prop-
erly to the hitch ball.
– the trailer lights connector is connect-
ed properly and trailer’s brake lights illu-
minate when the vehicle’s brake pedal
is pressed, and that the trailer’s turn sig- nal lights flash when the vehicle’s turn
signal lever is operated.
– the safety chains are connected prop-
erly.
– all cargo in the trailer is secured safe-
ty in position.
– the side mirrors provide a good rear-
ward field of view without a significant
blind spot.
y Sufficient time should be taken to learn
the “feel” of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up.
T Driving with a trailer
y You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may re-
sult in skidding or jackknifing and loss of
control.
y Avoid abrupt starts and sudden acceler-
ations. If your vehicle has a manual trans-
mission, always start out in first gear and
release the clutch at moderate engine rev-
olution.
y Avoid uneven steering, sharp turns and
rapid lane changes.
y Slow down before turning. Make a long-
er than normal turning radius because the
trailer wheels will be closer than the vehi-
cle wheels to the inside of the turn. In a
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’s electrical
system and cause a malfunction of
your vehicle’s lighting system.
y
Never exceed 45 mph (72 km/h)
when towing a trailer in hilly coun-
try on hot days.yWhen towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. For
safety’s sake, you should employ
extra caution when towing a trail-
er and you should never speed.
You should also keep the follow-
ing tips in mind:
