Instrum ents and controlsIgnition switch
The ignition switch has four positions:
LOCK, ACC, ON and START.
LOCK
The key can only be inserted or removed
in this position. The ignition switch will lock
the steering wheel when you remove the
key.
If turning the key is difficult, turn the steer-
ing wheel slightly to the right and left as
you turn the key.
Automatic transmission vehicles
The key can be turned from “ACC ” to
“ LOCK ” only when the selector lever is in
the “P ” position.Manual transmission vehicles
The key can be turned from “ACC ” to
“ LOCK ” only when the key is pushed in
while turning it.

300565
300566
Never turn the ignition switch to “ LOCK ” while the vehicle is being
driven or towed because that will
lock the steering wheel, prevent-
ing steering control. And when
the engine is turned off, it takes a
much greater effort than usual to
steer.

Starting the engine
Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and acces-
sories.
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 ” po-
sition and check the operation of the warn-
ing 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 accelera-
tor pedal. Release the key immediately af-
ter the engine has started. If the engine does not start, try the follow-
ing.
1) Turn the ignition switch to the “OFF ”
position and wait for at least 10 sec-
onds. After checking that the parking
brake is firmly set, turn the ignition
switch to the “START ” position while de-
pressing 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 ” posi-
tion and wait for at least 10 seconds.
Then fully depress the accelerator ped-
al 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 ” posi-
tion. 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, con-
tact 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 auto-
matically lowers the idle speed as the en-
gine warms up.
NOTE
The engine may be difficult to start
when the battery has been disconnect-
ed 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 approximately 10
seconds before starting the engine.
Automatic transmission vehi-
cle
1. Apply the parking brake.
2. Turn off unnecessary lights and acces-
sories.
3. Shift the selector lever to the “P ” or “N ”
position (preferably “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 ” po-
sition and check the operation of the warn-
ing 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 accelera-
tor pedal. Release the key immediately af-
ter the engine has started.
If the engine does not start, try the follow-

Manual transmission – 6
speeds (WRX-STI)
The manual transmission is a fully syn-
chromeshed, 6-forward-speed and 1-re-
verse-speed transmission.
The shift pattern is shown on the shift le-
ver knob.
Selecting reverse gear
1) Slider
You must raise the slider and hold it in that
position before you can move the shift le-
ver 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
Recommended shifting speeds
The best compromise between fuel econ-
omy and vehicle performance during nor-
mal driving is ensured by shifting up at the
speeds listed in the following table.
700140
Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral posi-
tion. Engine braking has no effect in
either of these conditions and the
risk of an accident is consequently
increased.

The manual transmission is a fully syn-
chromeshed, 5-forward-speed and 1-re-
verse-speed transmission.
The shift pattern is shown on the shift le-
ver knob. When shifting from 5th gear to
reverse gear, first return 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.

Maximum allowable speeds
The following table shows the maximum
speeds that are possible with each differ-
ent gear.
Never exceed the speed limit listed in the
following table for each gear position ex-
cept for brief acceleration in an emergen-
cy. The tachometer ’s needle will enter the
red area if these speeds are exceeded.
Failure to observe this precaution can
lead to excessive engine wear and poor
fuel economy.

7-18 Starting and operating
the original gear position.
While climbing a grade
When driving up hill, undesired upshift to
4th gear is prevented from taking place
when the accelerator pedal is released.
This minimizes the chances of subse-
quent downshifting to a lower gear when
accelerating again. This prevents repeat-
ed upshifting and downshifting resulting in
a smoother operation of the vehicle.
NOTE
The transmission may downshift to
2nd or 1st gear, depending on the way
the accelerator pedal is pressed to ac-
celerate the vehicle again.
While going down a hill
When descending a steep hill, depressing
the brake pedal will cause the transmis-
sion to downshift to 3rd gear, thus apply-
ing engine braking. Reacceleration for a
short time will cause the transmission to
upshift normally.
NOTE
In some cases, depressing the brake
pedal on a downhill grade does not re-
sult in an automatic downshift to 3rd
gear. This can happen when the auto-
matic transmission fluid temperature is
very low, for example, during driving shortly after the vehicle has been
parked for an extended period of time.
When the ATF temperature has risen to
a certain level, automatic downshift
normally takes place. In the meantime,
downshift manually for engine braking
as required.
Also, downshifting when braking
downhill will not occur at speeds
above approximately 48 mph (78 km/h).
3 (Third)
This position is for using engine braking
when going down a hill or for climbing a
grade.
The transmission automatically shifts into
a suitable gear from 1st to 3rd according
to the vehicle speed and the acceleration
you require.
When more acceleration is required in this
position, press the accelerator pedal fully
to the floor and hold that position. The
transmission will automatically downshift
to 2nd or 1st gear. When you release the
pedal, the transmission will return to the
original gear position.
2 (Second)
This position is for using engine braking
when going down a hill or for climbing a
steep grade.
In this position, the transmission holds in the 2nd gear.
Use this position when starting off from a
standstill on slippery road surfaces such
as mud or snow. It will ensure greater trac-
tion.
1 (First)
This position is for driving up or down very
steep grades, or driving through mud or
sand, or on slippery surfaces. In this posi-
tion, the transmission holds in the 1st
gear.
Maximum speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When shifting down a gear, it is important
to confirm that the current vehicle speed is
not in excess of the Maximum Allowable
Speed of the gear which is about to be se-
lected.

Parking your vehicle
Parking brake
To set the parking brake, press the brake
pedal firmly and hold it down while fully
pulling up the parking brake lever.
To release the parking brake, pull the le-
ver up slightly, press the release button,
then lower the lever while keeping the but-
ton pressed.
When the parking brake is set while the
engine is running, the parking brake warn-
ing light comes on. After starting the vehi-
cle, be sure that the warning light has
gone out before the vehicle is driven. Re-
fer to the “Warning and indicator lights ”
section (chapter 3).
Parking tips
When parking your vehicle, always set the
parking brake firmly and put the shift lever
in the “1 ” (1st) for an upgrade or “R ” (Re-
verse) for a downgrade for manual trans-
mission vehicles, or in the “P ” (Park) posi-
tion for automatic transmission vehicles.
Always set the parking brake firmly when
parking your vehicle. Never rely on the
transmission alone to hold the vehicle.
Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
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.
700336
Never drive while the parking brake
is set because this will cause unnec-
essary wear on the brake linings.
Before starting to drive, always
make sure that the parking brake
has been fully released.

7-28 Starting and operating
The vehicle will maintain the desired
speed.
Vehicle speed can be temporarily in-
creased while driving with the cruise con-
trol activated. Simply depress the acceler-
ator pedal to accelerate the vehicle. When
the accelerator pedal is released, the ve-
hicle will return to and maintain the previ-
ous cruising speed.
To temporarily cancel the
cruise control
There are five ways to cancel the cruise
control temporarily:
Pull the control lever in the “CANCEL ”
direction.
Depress the brake pedal.
Depress the clutch pedal (manual trans-
mission vehicles only).
Shift the selector lever into the “N ” posi-
tion (automatic transmission vehicles
only).
Shift the shift lever into neutral position
(manual transmission vehicles only).
The “ ” indicator light in the combi-
nation meter goes off when the cruise
control is cancelled.
To resume the cruise control after it has
been temporarily canceled and with vehi-
cle speed of approximately 20 mph (32
km/h) or more, push the control lever up-
ward in the “RES/ACC ” direction to return
to the original cruising speed automatical-
ly.
The “ ” indicator light in the combi-
nation meter will automatically come on at
this time.
To turn off the cruise control
There are two ways to turn off the cruise
control:
Push the main switch again.
Turn the ignition switch to the “ACC ” or
“ LOCK ” position (but only when the vehi-
cle is completely stopped).
To change the cruising speed
To increase the speed (by control le-
ver)
Push the control lever upward in the “ RES/ACC ” direction and hold it until the
vehicle reaches the desired speed. Then,
release the control lever. The vehicle
speed at that moment will be memorized
and treated as the new set speed.
When the difference between the actual
vehicle speed and the set speed is less
than 4 mph (6.8 km/h), the set speed can
be increased 1 mph (1.6 km/h) each time
by pressing the control lever upward in the “ RES/ACC ” direction quickly.
