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.

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.

is at the proper level but the light remains
on, contact your nearest SUBARU dealer
immediately.
AT OIL TEMPerature
warning light (AT vehi-
cles)
The AT oil temperature warning light
comes on when the ignition switch is
turned to the
“ON ” position and goes out
after approximately two seconds.
If this light comes on when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light comes on while driving, it is un-
necessary to stop the vehicle, but avoid
driving up steep grades or in stop and go
traffic.
Automatic transmission control
system warning
If the light flashes after the engine starts,
it may indicate that the automatic trans-
mission control system is not working
properly. Contact your nearest SUBARU dealer for service immediately.
Rear differential oil tem-
perature warning light
(WRX-STI)
If this light comes on when the engine is
running, it may indicate that the rear differ-
ential oil temperature is too hot.
At this time, the driver
’s control center dif-
ferential will automatically cancel the cur-
rent torque-distribution ratio setting and
adopts its minimum ratio.
If the light comes on while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place.
Park the vehicle for several minutes. After
the light goes out, you can start driving.
If the light does not go out, contact the
nearest SUBARU dealer for service.
NOTE
If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.
The rear differential oil will deterio-
rate if its temperature increases
enough for the rear differential oil tem-
perature warning light to come on. It is
advisable to have the rear differential
oil replaced as soon as possible.
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ” posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
comes on. Continued driving with
this light on can damage the rear dif-
ferential and other parts of the pow-
ertrain.
If the warning light behaves as fol-
lows, the ABS system may not work
properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.

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.

seconds, wait for ten seconds or
more before trying again.

7-16 Starting and operating
Automatic transmission
The automatic transmission is electroni-
cally controlled with 4-forward speeds and
1-reverse speed.
NOTE
When the engine coolant tempera-
ture is still low, your vehicle ’s automat-
ic transmission will up-shift at higher
engine speeds than when the coolant
temperature is sufficiently high in or-
der to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor-
mal timing after the engine has warmed
up.
Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
the on-board computer has collected
and stored in memory to allow the
transmission to shift at the most ap-
propriate times for the current condi-
tion of your vehicle. Optimized shifting
will be restored as the vehicle contin-
ues to be driven for a while.
Selector lever for automatic
transmission
Do not shift from the “P ” or “N ” po-
sition into the “D ”, “3 ”, “2 ”, “1 ” or
“ R ” position while depressing the
accelerator pedal. This may cause
the vehicle to jump forward or back-
ward.
Shift into the “P ” or “R ” position
only after the vehicle is complete-
ly stopped. Shifting while the ve-
hicle is moving may cause dam-
age to the transmission.
Do not race the engine for more
than five seconds in any position
except the “N ” or “P ” position
when the brake is set or when
chocks are used in the wheels.
This may cause the automatic
transmission fluid to overheat.
Avoid shifting from one of the for-
ward driving positions into the “ R ” position or vice versa until the
vehicle has completely stopped.
Such shifting may cause damage
to the transmission.
When parking the vehicle, first se-
curely apply the parking brake
and then place the selector lever
in the “P ” position. Avoid parking
for a long time with the selector le-
ver in any other position as doing
so could result in a dead battery.

: With the brake pedal depressed,
move the lever along the gate.
: Move the lever along the gate.
The selector lever has seven positions.
P (Park)
This position is for parking the vehicle and
starting the engine.
In this position, the transmission is me-
chanically locked to prevent the vehicle
from rolling freely.
When you park the vehicle, first set the
parking brake fully, then shift into the “P ”
position. Do not hold the vehicle with only
the transmission.
A shift interlock function is employed in
the automatic transmission system to en- sure safe starting of the vehicle.
To shift the selector lever from the
“P ” to
the any other position, you have to de-
press the brake pedal fully when the igni-
tion switch is in the “ON ” position. This
prevents the vehicle from lurching when it
is started.
If the shift lever does not move from the “ P ” position with the brake pedal de-
pressed, refer to the “Shift lock release ”
section in this chapter.
R (Reverse)
This position is for backing the vehicle.
To shift from the “N ” to “R ” position, first
stop the vehicle completely then move the
lever to the “R ” position.
N (Neutral)
This position is for restarting a stalled en-
gine.
In this position the wheels and transmis-
sion are not locked. In this position, the
transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless
the parking brake or foot brake is on.
Avoid coasting with the transmission neu-
tral.
During coasting, there is no engine brak-
ing effect.
NOTE
If you stop the engine with the selector
lever in the “N ” position, move the se-
lector lever to the “P ” position immedi-
ately. Otherwise, you may find that the
selector lever soon cannot be moved
to the “P ” position. If you find that the
selector lever cannot be moved from
the “N ” position to the “P ” position,
turn the ignition switch to the “ON ” po-
sition and try again.
D (Drive)
This position is for normal driving.
The transmission automatically shifts into
a suitable gear from 1st to 4th 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 3rd, 2nd or 1st gear. When you release
the pedal, the transmission will return to
700332
Do not drive the vehicle with the se-
lector lever in the “N ” (neutral) posi-
tion. Engine braking has no effect in
this condition and the risk of an ac-
cident is consequently increased.
