mitted to have higher sulfur levels, which may affect
the performance 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 problem is fuel related before returning your vehi-
cle to an authorized dealer for service. TMMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may deteriorate and the CHECK
ENGINE warning light/Malfunction indicator lamp 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. T 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 continu-
ously 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 con-
tain no more than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
In addition, some gasoline suppliers are now produc-
ing reformulated gasolines, which are designed to re-
duce 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 detergents and oxygenates and if they have
been reformulated to reduce vehicle emissions.
As additional guidance, only use fuels suited for your
vehicle as explained below.y
Fuel should be unleaded and have an octane rating
no lower than that specified in this manual.y 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 sufficient
quantities of the proper cosolvents and corrosion in-
hibitors required to prevent damage to the fuel system.
Do not use fuel containing methanol EXCEPT under

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.
y Never add any cleaning agents to the fuel
tank. The addition of a cleaning agent may
cause damage to the fuel system. y Make sure that the cap is tightened until it
clicks to prevent fuel spillage in the event of an
accident. 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. y 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 emis-
sion control system might be damaged.

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. y 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 y A vehicle passes
the OBD system inspection if
proper the “CHECK ENGINE” warning light/MIL illu-
mination is observed, there is no stored diagnostic
trouble codes, and the OBD system readiness moni-
tors 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 ENGINE”
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 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. y 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 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.

7-10
Starting and operating
If the engine does not start, try the following:
1) Turn the ignition switch to the “OFF” position and
wait for at least 10 seconds. After checking that the
parking brake is firmly set, turn the ignition switch to
the “START” position while depressing the acceler-
ator pedal slightly (about a quarter of the full stroke).
Release the accelerator pedal as soon as the en-
gine starts.
2) If this fails to start the engine, turn the ignition
switch back to the “OFF” position and wait for at
least 10 seconds. Then fully depress the accelerator
pedal and turn the ignition switch to the “START”
position. If the engine starts, quickly release the ac-
celerator pedal.
3) If this fails to start the engine, turn the ignition
switch again to the “OFF” position. After waiting for
10 seconds or longer, turn the ignition switch to the
“START” position without depressing the accelera-
tor pedal.
4) If the engine still refuses to start, contact your
nearest SUBARU dealer for assistance.
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.
NOTE
The engine may be difficult to start when the bat- tery has been disconnected and reconnected (for
maintenance or other purposes). This difficulty is
caused by the electronically controlled throttle’s
self-diagnosis function. To overcome it, keep the
ignition switch in the “ON” position for approxi-
mately 10 seconds before starting the engine. „
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, try the following: 1) Turn the ignition switch to the “OFF” position and
wait for at least 10 seconds. After checking that the
parking brake is firmly set, turn the ignition switch to
the “START” position while depressing the acceler-

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. y 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.
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 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.
yDriving 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. y 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.

adjusts 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 surfac-
es, thereby helping to maintain traction and directional
control. Activation of this function is shown by steady
illumination of the Vehicle Dynamics 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 op-
erations. Activation of this function is shown by flash-
ing of the Vehicle Dynamics Control operation indica-
tor light.
NOTE y Slight twitching of the brake pedal may be felt
when the Vehicle Dynamics Control system oper-
ates; a small degree of vehicle or steering wheel
shaking may also be noticed in this situation.
These are normal characteristics of Vehicle Dy-
namics Control operation and are no cause for
alarm. y
When driving off immediately after starting the
engine, a short-lived operation noise may be no-
ticed coming from the engine compartment. This
noise is generated as a result of a check being per-
formed on the Vehicle Dynamics Control system
and is normal. y Depending on the timing of activation of the
brakes, certain situations may occur just after
driving off where the brake pedal seems to exhibit
a jolting motion. This too is a consequence of the
Vehicle Dynamics Control operational check and
is normal. y In the circumstances listed below, the vehicle
may be more unstable than it feels to the driver.
The Vehicle Dynamics Control System may there-
fore operate. Such operation does not indicate a system fault. yon gravel-covered or rutted roads
