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-

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.

Starting and operating
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.

Shift into reverse ONLY when the vehicle has
completely stopped. It may cause damage to
the transmission to try shifting into reverse
when the vehicle is moving.
„ 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.

Manual transmission – 5 speeds (ex-
cept WRX-STi)
The manual transmission is a fully synchromeshed, 5-
forward-speed and 1-reverse-speed transmission.
The shift pattern is shown on the shift lever knob.
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.
