State emission testing (U.S. only)
At state inspection time, remember to tell your in-
spection or service station in advance not to place
your Subaru AWD vehicle on a two-wheel dyna-
mometer. Otherwise, serious transmission dam-
age will result.
Some states have started using dynamometers in
their state inspection programs in order to meet their
obligation under federal law to implement stricter vehi-
cle emission standards to reduce air pollution from ve-
hicles. A dynamometer is a treadmill or roller-like test-
ing device that allows your vehicle’s wheels to turn
while the vehicle remains in one place. Depending on
the severity of a state’s air pollution problems, the
states must adopt either a “basic” or “enhanced” vehi-
cle emission inspection test. Normally, a portion of the
basic emission test consists of an emission inspector
inserting an analyzer probe into the exhaust pipe of an
idling vehicle for a short period of time. States with
more severe air pollution problems are required to
adopt an enhanced vehicle emission test. This test
simulates actual driving conditions on a dynamometer
and permits more accurate measurement of tailpipe
emitted pollution than the basic emission test.
The U.S. Environmental Protection Agency (EPA) and states using two-wheel dynamometers in their emis-
sion testing programs have
EXEMPTED Subaru 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
NEVER be performed on a single two-wheel dy-
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 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).

Manual transmission – 6 speeds
(WRX-STi)
The manual transmission is a fully synchromeshed, 6-
forward-speed and 1-reverse-speed transmission.
The shift pattern is shown on the shift lever knob.
Do not drive the vehicle with the clutch disen-
gaged (i.e., when the clutch pedal is depressed)
or with the shift lever in the neutral position.
Engine braking has no effect in either of these
conditions and the risk of an accident is conse-
quently increased.
„ Selecting reverse gear
1) Slider
You must raise the slider and hold it in that position be-
fore you can move the shift lever to the “R” position.
To change gears, fully depress the clutch pedal, move
the shift lever, and gradually let up on the clutch.
If it is difficult to shift into gear, put the transmission in
neutral, release the clutch pedal momentarily, and
then try again.

„ Shifting speeds
T Recommended shifting speeds
The best compromise between fuel economy and ve-
hicle performance during normal driving is ensured by
shifting up at the speeds listed in the following table. T
Maximum allowable speeds
The following tables show the maximum speeds that
are possible with each different gear. The tachome-
ter’s needle will enter the red area if these speeds are
exceeded.
With the exception of cases where sudden accelera-
tion is required, the vehicle should not be driven with
the tachometer’s needle inside the red area. Failure to
observe this precaution can lead to excessive engine
wear and poor fuel economy.
When shifting down a gear, ensure that the ve-
hicle is not travelling at a speed exceeding the
Maximum Allowable 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 slip-
pery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost
and the risk of an accident increased.
NOTE
Never exceed posted speed limits. „
Driving tips
Do 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 compo-
nents.
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
5th, 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. Re-
member, if you “ride” (over use) the brakes while de-
scending a hill, they may overheat and not work prop-
erly.
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.

When shifting from 5th gear to reverse gear, first re-
turn the shift lever to the neutral position then shift into
reverse gear.
To change gears, fully depress the clutch pedal, move
the shift lever, and gradually let up on the clutch pedal.
If it is difficult to shift into gear, put the transmission in
neutral, release the clutch pedal momentarily, and then try again.
