The key can be turned from “ACC” to “LOCK” only
when the selector lever is in the “P” position. T
Manual transmission vehicles
The key can be turned from “ACC” to “LOCK” only
when the key is pushed in while turning it.
y Never turn the ignition switch to “LOCK”
while the vehicle is being driven or towed be-
cause 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.y
Before leaving the vehicle, always remove
the key from the ignition switch for safety and
never allow an unattended child to remain in
the vehicle. Failure to follow this procedure
could result in injury to a child or others. They
could operate the power windows, the sunroof
or other controls or even make the vehicle
move.
„ ACC
In this position the electrical accessories (radio, ciga-
rette lighter, etc.) can be used. „ ON
This is the normal operating position after the engine
is started. „ START
The engine is started in this position. The starter
cranks the engine to start it. When the key is released
(after the engine has started), the key automatically
returns to the “ON” position.

condition has been detected which may damage the
emission control system.
To prevent serious damage to the emission control
system, you should do the following:
yReduce vehicle speed.
y Avoid hard acceleration.
y Avoid steep uphill grades.
y Reduce the amount of cargo, if possible.
y Stop towing a trailer as soon as possible.
The CHECK ENGINE warning light may stop blinking
and come on steadily after several driving trips. You
should have your vehicle checked by an authorized
SUBARU dealer immediately. „ Charge warning light
If this light comes on when the engine is running, it
may indicate that the charging system is not working
properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the alternator belt. If the belt is
loose, broken or if the belt is in good condition but the
light remains on, contact your nearest SUBARU deal-
er immediately. „
Oil pressure warning light
If this light comes on when the engine is running, it
may indicate that the engine oil pressure is low and the
lubricating system is not working properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the engine oil level. If the oil lev-
el is low, add oil immediately. If the engine oil is at the
proper level but the light remains on, contact your
nearest SUBARU dealer immediately.
Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.
„ AT OIL TEMPerature warning
light (for AT vehicles)
The AT oil temperature warning light comes on when
the ignition switch is turned to the “ON” position and
goes out after about two seconds.
If this light comes on when the engine is running, it
may indicate that the automatic transmission fluid tem-
perature is too hot.

If the light comes on while driving, it is unnecessary to
stop the vehicle, but avoid driving up steep grades or
in stop and go traffic. TAutomatic transmission control system warn- ing
If the light flashes after the engine starts, it may indi-cate that the automatic transmission control system is
not working properly. Contact your nearest SUBARU
dealer for service immediately. „ Rear differential oil temperature
warning light (WRX-STi)
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 differential
and other parts of the powertrain.
If this light comes on when the engine is running, it
may indicate that the rear differential oil temperature is
too hot.
At this time, the driver’s control center differential will automatically cancel the current torque-distribution ra-
tio 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 y
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 tem-
perature.y The rear differential oil will deteriorate if its tem-
perature increases enough for the rear differential
oil temperature warning light to come on. It is ad-
visable 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” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.

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. „

Starting and operating
Automatic transmission
The automatic transmission is electronically controlled
with 4-forward speeds and 1-reverse speed.
NOTE
Immediately after a disconnected battery is recon-
nected (Turbo model only) or ATF (automatic
transmission fluid) is replaced, you may feel that
the automatic transmission operation is some-
what unusual.
This results from erasure or invalidation of data
the on-board computer has collected and stored in memory to allow the transmission to shift at the
most appropriate times for the current condition
of your vehicle. Optimized shifting will be restored
as the vehicle continues to be driven for a while.
Do not shift from the “P” or “N” position into
the “D”, “3”, “2”, “1” or “R” position while de-
pressing the accelerator pedal. This may cause
the vehicle to jump forward or backward.
y
Shift into the “P” or “R” position only after
the vehicle is completely stopped. Shifting
while the vehicle is moving may cause damage
to the transmission.y Do not race the engine for more than five sec-
onds in any position except the “N” or “P” po-
sition when the brake is set or the tires are on
blocks. This may cause the automatic transmis-
sion fluid to overheat. y Avoid shifting from one of the forward driving
positions into the “R” position or vice versa un-
til the vehicle has completely stopped. Such
shifting may cause damage to the transmis-
sion.
