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 tracks. 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” warn-
ing light/malfunction indicator lamp (MIL) and an ex-
amination 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 illumi-
nation is observed, there is no stored diagnostic trou-
ble 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 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 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 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, trunk 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 “ON” position while depressing the accelerator
pedal slightly (about a quarter of the full stroke). Re-
lease 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 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. „
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 “ON” position while depressing the accelerator
pedal slightly (about a quarter of the full stroke). Re-
lease 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 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 out after the engine has started. The fuel injec-
tion system automatically lowers the idle speed as the
engine warms up.
While the engine is warming up, make sure that the
selector lever is at the “P” or “N” position and that the
parking brake is applied.
If you restart the engine while the vehicle is
moving, shift the selector lever into the “N” po-sition. Do not attempt to place the selector lever
of a moving vehicle into the “P” position.
Stopping the engine
The ignition switch should be turned off only when the
engine is idling.
Do not stop the engine when the vehicle is mov-
ing. This will cause loss of power to the power
steering and the brake booster, making steer-
ing and braking more difficult. It could also re-
sult in accidental activation of the “LOCK” po-
sition on the ignition switch, causing the steer-
ing wheel to lock.

Driver’s Control Center Differential
(DCCD) (WRX-STi)
Always use the utmost care when driving. Be-
ing overconfident because you are driving a ve-
hicle with a driver’s control center differential
could easily lead to a serious accident.
In the event of failure of the driver’s control
center differential, the “ ” indicator light will
flash and the auto mode and manual mode will
both stop functioning. Have the vehicle in-
spected by your Subaru dealer.
„ Auto mode
This system automatically adjusts the differential-ac-
tion limiting factor (torque-distribution ratio between
the front and rear wheels) of the center differential to

suit driving and road-surface conditions. When the ig-
nition switch is turned ON, the “AUTO” indicator light
in the combination meter comes on. The system can
be switched to a manual mode. „Manual mode
The manual mode allows the driver to set the differen-
tial-action limiting factor of the center differential as
desired to suit driving and road-surface conditions.
When this mode is selected, the “AUTO” indicator light
in the combination meter goes off. T Manual switch
Press the “DCCD-MANU” switch on the center con- sole to switch from auto mode to manual mode. The
“AUTO” indicator light in the combination meter will go
off. Press the switch again to go back to auto mode.
The “AUTO” indicator light in the combination meter
will come on. T
Center differential control dial and indicator
light
The control dial is located beside the parking-brake le-
ver. By turning the control dial forward and rearward,
it is possible to change the differential-action limiting
factor of the center differential.
The center-differential indicator lights in the combina-
tion meter give six levels of indication. The indicator

lights and control dial are linked; when the dial is
turned to change the differential-action limiting factor
(front/rear torque-distribution ratio), the illumination
position of the indicator lights change accordingly.
Turn the dial forward to increase the differential-action
limiting factor. If the white line on the dial reaches the
frontmost position, the center differential will be almost
completely locked and the “LOCK” indicator light will come on.
Turn the dial rearward to reduce the differential-action
limiting factor. If the white line on the dial reaches the
rearmost position, the factor will be minimal and the
“ ” indicator light will come on.
y
Do not turn the control dial when a wheel slip-
page occurs. Wait until the wheelspin has been
brought under control or select the auto mode. y When the vehicle has been fitted with a tem-
porary spare tire or is to be towed, turn the con-
trol dial fully rearward (to minimize the differen-
tial-action limiting factor) or select the auto

mode.
NOTE yIf the differential-limiting factor is large during
cornering maneuvers, a small speed difference
between the front and rear wheels may cause tight
corner braking (a phenomenon accompanied by
vibration and noise). This phenomenon does not
indicate a problem. It will disappear if the differen-
tial-action limiting factor is reduced.y Use the center-differential indicator light only as
a rough indication of the differential-action limit-
ing factor.y If you rapidly depress and release the accelera-
tor pedal while driving at low speed, you may hear
a knocking sound from the vicinity of the center
differential and rear differential. This sound oc-
curs because of the structure of the center differ-
ential. It does not indicate a problem. „ Temporary release
When the driver stop the vehicle and pulls the parking-
brake lever after manually setting the differential-ac-
tion limiting factor, the factor is temporarily minimized.
The indicator in the combination meter continues to
show the driver’s selected differential-action limiting factor. When the driver releases the parking-brake le-
ver, the factor set by the driver is restored.
