Starting and operating
CAUTION
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.
The EPA has issued regulations for
inspecting the On-Board Diagnostic
(OBD) system as part of the state emis-
sions inspection. The OBD system is
designed to detect engine and transmis-
sion 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. Over 30 states plus the District of
Columbia have implemented the OBD
system inspection.
. The inspection of the OBD system
consists of a visual operational check of
the “CHECK ENGINE ”warning light/mal-
function indicator lamp (MIL) and an
examination of the OBD system with an
electronic scan tool while the engine is
running.
. Avehicle
passes the OBD system
inspection if proper illumination of the
“CHECK ENGINE ”warning light/MIL is
observed, there are nostored diagnostic trouble codes, and the OBD system
readiness monitors are complete.
.
A vehicle
fails the OBD inspection if the
“CHECK ENGINE ”warning light/MIL is
not properly operating or there are one or
more diagnostic trouble codes stored in
the 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 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.
. 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
inflation.
3. Look under the vehicle for any sign of
leaks.
4. Check that the hood, trunk (4-door)
and rear gate (5-door) 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.

Starting the 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.
. For non-turbo models, to protect the
engine while the shift lever is in the
neutral position (MT models)/select
lever is in the “P ” or “N ” position (AT
models), the engine is controlled so
that the engine speed may not become
too high even if the accelerator pedal is
depressed hard.
& MT models1. Apply the parking brake.
2. Turn off unnecessary lights and ac-
cessories.
3. Depress 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 depressed 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
“Warning and indicator lights ”F 3-13.
5. Turn the ignition switch to the “START”
position without depressing the accelera-
tor 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 accelerator pedal
slightly (approximately a quarter of the
full stroke). Release the accelerator
pedal as soon as the engine 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 accel-
erator pedal and turn the ignition
switch to the “START”position. If the
engine starts, quickly release the
accelerator 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 accelerator 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 turned off after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the
engine warms up.
& AT models1. Apply the parking brake.
2. Turn off unnecessary lights and ac-
cessories.
3. Shift the select lever to the “P”or “N”
position (preferably the “P”position).
The starter motor will only operate when
the select lever is at the “P”or “N”position.
4. Turn the ignition switch to the “ON”

While the engine is warming up, make
sure that the select lever is at the “P”or
“N ”position and that the parking brake is
applied.
CAUTION
If you restart the engine while the
vehicle is moving, shift the select
lever into the “N ” position. Do not
attempt to place the select lever of a
moving vehicle into the “P ” posi-
tion.
Stopping the engineThe ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
WARNING
Do not stop the engine when the
vehicle is moving. This will cause
loss of power to the power steering
and the brake booster, making steer-
ing and braking more difficult. It
could also result in accidental acti-
vation of the “LOCK ”position on the
ignition switch, causing the steering
wheel to lock.

WARNING
When shifting down a gear, ensure
that the vehicle is not travelling at a
speed exceeding the Maximum Al-
lowable Speed for the gear which is
about to be selected. Failure to
observe this precaution can lead to
engine over-revving and this in turn
can result in engine damage.
In addition, sudden application of
engine brakes when the vehicle is
travelling on a slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident
increased.
NOTENever exceed the posted speed limit.&
Driving tipsDo not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an
upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components.
When it is necessary to reduce vehicle
speed due to slow traffic, turning corners,
or driving up steep hills, downshift to a
lower gear before the engine starts to
labor.
On steep downgrades, downshift the
transmission to 4th, 3rd or 2nd gear as
necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you “ride”(over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
Driver ’s Control Center Dif-
ferential (DCCD) (STI)
WARNING
Always use the utmost care when
driving. Being overconfident be-
cause you are driving a vehicle with
a driver ’s control center differential
could easily lead to a serious acci-
dent.
CAUTION
All the indicator lights will flash in
the event that the driver ’s control
center differential has a malfunc-
tion. Have the vehicle inspected by
your SUBARU dealer.
The driver ’s control center differential
allows you to freely change the degree
of limitation of the d ifferential action
(limited slip differential (LSD) torque) of
your vehicle’ s center differential.
By using the center differential control
switch, you can set an initial LSD torque to
match the road surface conditions, driving
conditions and your driving style.

Starting and operating
system warning light and ABS warning
light illuminate simultaneously.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
during driving.
Even if the EBD system malfunctions, the
conventional braking system will still func-
tion. However, the rear wheels will be
more prone to locking when the brakes
are applied 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 location.
2. Shut down the engine, apply the
parking brake, and then restart it.
3. Release the parking brake. If both
warning lights turn off, the EBD system
may be malfunctioning. Drive carefully to
the nearest SUBARU dealer and have the
system inspected.
4. If both warning lights illuminate again
and remain illuminated after the engine
has been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level. Refer to “Brake fluid”
F 11-25. 5. If the brake fluid level is not below the
“MIN
”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
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.
WARNING
. Driving with the brake system
warning light illuminated is dan-
gerous. This indicates your brake
system may not be working
properly. If the light remains
illuminated, have the brakes in-
spected by a SUBARU dealer
immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.
Vehicle Dynamics Control
system
WARNING
Always use the utmost care in
driving –overconfidence because
you are driving with a Vehicle Dy-
namics Control system equipped
vehicle could easily lead to a ser-
ious accident.
CAUTION
. Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.
. Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-
namics Control is no guarantee

Jump starting
WARNING
. Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you,
thoroughly flush the exposed
area with water immediately. Get
medical help if the fluid has
entered your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and obtain immediate medical
help.
Keep everyone including chil-
dren away from the battery.
. The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.
. Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
. Whenever working on or around
a battery, always wear suitable eye protectors, and remove metal
objects such as rings, bands or
other metal jewelry.
. Be sure the jumper cables and
clamps on them do not have
loose or missing insulation.
Do not jump start unless cables
in suitable condition are avail-
able.
. A running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away
from the cooling fan, belts and
any other moving engine parts.
Removing rings, watches and
ties is advisable.
. Jump starting is dangerous if it
done incorrectly. If you are un-
sure about the proper procedure
for jump starting, consult a com-
petent mechanic.
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
& How to jump start1. Make sure the booster battery is 12
volts and the negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and
accessories.
4. Connect the jumper cables exactly in
the sequence illustrated.
