2. Remove the fuel filler cap by turning it slowly coun-
terclockwise.
Gasoline vapor is highly flammable. Before
refueling, always first stop the engine and make
sure that there are no lighted cigarettes, open
flames or electrical sparks in the adjacent area. When opening the cap, do not remove the
cap quickly. Fuel may be under pressure and
spray out of the fuel filler neck especially in hot
weather, which may cause injury.
3. Stop filling the tank after the fuel filler pump auto-
matically 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 un-
der 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
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” section located in
chapter 3.
Never add any cleaning agents to the fuel
tank. The addition of a cleaning agent may
cause damage to the fuel system. Make sure that the cap is tightened until it
clicks to prevent fuel spillage in the event of an
accident.

states using two-wheel dynamometers in their emis-
sion testing programs have EXEMPTEDSubaru AWD
vehicles from the portion of the testing program that in-
volves a two-wheel dynamometer.
There are some states that use four-wheel dynamom-
eters in their testing programs. When properly used,
that equipment will not damage an AWD Subaru vehi- cle.
Under no circumstances should the rear wheels be
jacked off the ground, nor should the driveshaft be dis-
connected for state emission testing.
Testing of an All-Wheel Drive vehicle must
NEVERbeperformedonasingletwo-wheeldy-
namometer. Attempting to do so will result in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.
Resultant vehicle damage due to improper test-
ing is not covered under the SUBARU Limited
Warranty and is the responsibility of the state inspection program or its contractors or licens-
ees.
The EPA has issued regulations for inspecting the On-
Board Diagnostic (OBD) system as part of the state
emissions inspection. The OBD system is designed to
detect engine and transmission problems that might
cause vehicle emissions to exceed allowable limits.
These inspections apply to all 1996 model year and
newer passenger cars and light trucks. Several states
plus the District of Columbia have opted to start the
OBD system inspection prior to the required EPA reg-
ulation effective date of January 1, 2002. Other states
will add OBD system inspection in 2002. The inspection of the OBD system consists of a vi-
sual operational check of the “CHECK ENGINE”
warning light/malfunction indicator lamp (MIL) and an
examination of the OBD system with an electronic
scan tool while the engine is running A vehicle passes
the OBD system inspection if
proper the “CHECK ENGINE” warning light/MIL illu-
mination is observed, there is nostored diagnostic
trouble codes, and the OBD system readiness moni-
tors 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 ENGINE”
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 three. Under
this condition, the vehicle operator should be instruct-
ed 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 adjust-
ments 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 inflation.
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 mir-
rors.
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” po-sition.
9. Check the gauges, indicator and warning lights af-
ter starting the engine.
NOTE
Engine oil, engine coolant, brake fluid, washer flu-
id and other fluid levels should be checked daily,
weekly or at fuel stops.

Starting and operating
–CONTINUED –
Starting the engine
Do not operate the starter motor continuously
for more than ten seconds. If the engine fails to
start after operating the starter for five to ten
seconds, wait for ten seconds or more before
trying again.
Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Press the clutch pedal to the floor and shift the shift
lever into neutral. Hold the clutch pedal to the floor
while starting the engine.
The starter motor will only operate when the clutch
pedal is pressed fully to the floor.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning and indicator lights.
Refer to the “Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START” position
without depressing the accelerator pedal. Release
the key immediately after the engine has started. If the engine does not start within ten seconds, wait a
while and then turn the ignition switch to the “START”
position again while depressing the accelerator pedal
half way down.
6. Confirm that all warning and indicator lights have
gone off after the engine has started. The fuel injection
system automatically lowers the idle speed as the en-
gine warms up.
Automatic transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Shift the selector lever to the “P” or “N” position
(preferably “P” position).
The starter motor will only operate when the select le-
ver is at the “P” or “N” position.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning and indicator lights.
Refer to the “Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START” position
without depressing the accelerator pedal. Release
the key immediately after the engine has started.
If the engine does not start within ten seconds, wait a
while and then turn the ignition switch to the “START”
position again while depressing the accelerator pedal

cles. 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, there-
fore, reduce your speed and leave ample dis-
tance from other vehicles. When you feel the ABS system operating,
you should maintain constant brake pedal pres-
sure. Do not pump the brake pedal since doing
so may defeat the operation of the ABS system.
ABS system self-check
You may feel a slight shock in the brake pedal and
hear the operating sound of ABS from the engine com-
partment just after the vehicle is started. This is
caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnor-
mal condition.
ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
When driving with an insufficient battery voltage such
as when the engine is jump started, the ABS warning
light may come on. This is due to the low battery volt-
age and does not indicate a malfunction. When the
battery becomes fully charged, the light will go out.

light illuminate simultaneously, take the following steps:
1. Stop the vehicle in the nearest safe, flat place. If
you cannot avoid parking the vehicle on a slope, use
chocks to prevent the vehicle from moving.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both warning lights go
out, the system is normal and no further action is nec-essary.
4. If both warning lights come on again and stay illu-
minated 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 inspect-
ed.
6. If the brake fluid level is below the “MIN” mark, DO
NOT drive the vehicle. Instead, have the vehicle towed
to the nearest SUBARU dealer for repair.

Driving with the brake system warning light
on is dangerous. This indicates your brake sys-
tem may not be working properly. If the light re-
mains on, have the brakes inspected by a
SUBARU dealer immediately.
If at all in doubt about whether the brakes are
operating properly, do not drive the vehicle.
Have your vehicle towed to the nearest
SUBARU dealer for repair.

Driving tips

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 outside of the rim. 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 com-
pletely through the stream. The water should be shal-
low enough that it does not reach the vehicle’s
undercarriage. Water entering the engine air intake or
the exhaust pipe or water splashing onto electrical
parts may damage your vehicle and may cause it to
stall. Never attempt 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 trac-
tion and even vehicle rollover. Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads. Do not drive or park over or near flammable materi-
als such as dry grass or fallen leaves, as they may
burn easily. The exhaust system is very hot while the
engine is running and right after the engine stops. This
could create a fire hazard.
After driving through tall grass, mud, rock, sand, riv-
ers, 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 under-
body. If the vehicle is use d with these materials
trapped or adhering to the underbody, a mechanical
breakdown or fire could occur. Secure all cargo carried inside the vehicle 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 injury. 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. If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and move
the selector lever back and forth between “D” and “R”
repeatedly. Do not race the engine. For the best pos-
sible traction, avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely slippery, you can
obtain better traction by starting the vehicle with the
transmission in 2nd than 1st (both for MT and AT). Never equip your vehicle with tires larger than those
specified in this manual. Frequent driving of an AWD vehicle under hard-driv-
ing conditions such as rough roads or off roads will ne-

result in an oil leak.
11.Close the access cover by turning it clockwise and
reinstall the six clips in their original positions.
12.Pour engine oil through the filler neck.
Oil quantity (guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of oil depends on the quantity
of oil that has been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil
and the time the oil is left flowing out. After pouring oil
into the engine, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal.
14.Run the engine until it reaches the normal operat-
ing temperature. Then stop the engine and wait a few
minutes to allow the oil drain back. Check the oil level
again and if necessary, add more engine oil.
Recommended grade and viscosity
Oil grade:
API classification SL or SJ with the words “ENER-
GY CONSERVING” (if you cannot obtain the oil
with the SL or SJ grade, you may use SH or SG
grade oil.) or the new API certification mark (Star-
burst mark) displayed on the container.
API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities

Maintenance and service
Any absorbed moisture can cause improper
clutch operation.
If the vehicle requires frequent refilling, there
may be a leak. If you suspect a problem, have
the vehicle checked at your SUBARU dealer. Never use different brands of clutch fluid to-
gether. When clutch fluid is added, be careful not to
allow any dirt into the tank.
Recommended clutch fluid
FMVSS No. 116, fresh DOT 3 or 4 brake fluid
Brake booster
If the brake booster does not operate as described be-
low, have it checked by your SUBARU dealer.
1. With the engine off, depress the brake pedal sever-
al times, applying the same pedal force each time. The
distance the pedal travels should not vary.
2. With the brake pedal depressed, start the engine.
The pedal should move slightly down to the floor.
3. With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds. The
pedal height should not change.
4. Start the engine again and run for about one minute
then turn it off. Depress the brake pedal several times
to check the brake booster. Brake booster operates
properly if the pedal stroke decreases with each de-
pression.

Brake pedal
Check the brake pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. Checking the brake pedal free play
1) 0.04–0.12in(1.0–3.0mm)
Stop the engine and firmly depress the brake pedal
several times. Lightly press the brake pedal down with
one finger to check the free play with a force of less
than2lb(10N,1kg).
If the free play is not within proper specification, con- tact your SUBARU dealer.
Checking the brake pedal reserve dis- tance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approximately 66 lb
(294 N, 30 kg) and measure the distance between the
upper surface of the pedal pad and the floor.
When the measurement is smaller than the specifica-
tion, or when the pedal does not operate smoothly,
contact with your SUBARU dealer.
