Ignition switch
WARNING
. Never turn the ignition switch to
“ LOCK ”while the vehicle is
being driven or towed because
that will lock the steering wheel,
preventing steering control. And
when the engine is turned off, it
takes a much greater effort than
usual to steer.
. Before leaving the vehicle, al-
ways 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. Children could operate
the power windows, the moon-
roof or other controls or even
make the vehicle move.
CAUTION
Do not attach a large key holder or
key case to either key. If it banged
against your knees or hands while
you are driving, it could turn the
ignition switch from the “ON ”posi- tion to the
“Acc ”or “LOCK ”posi-
tion, thereby stopping the engine.
Also, if the key is attached to a
keyholder or to a large bunch of
other keys, centrifugal force may act
on it as the vehicle moves, resulting
in unwanted turning of the ignitionswitch.
The ignition switch has four positions:
LOCK, Acc, ON and START. NOTE . Keep the ignition switch in the
“ LOCK ”position when the engine is
not running. . Using electrical accessories for a
long time with the ignition switch in the
"ON" or “Acc ”position can cause the battery to go dead..
If the ignition switch will not move
from the “LOCK ”position to the “Acc ”
position, turn the steering wheel
slightly to the left and right as you turn
the ignition switch. & 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
steering 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.
& Acc
In this position the electrical accessories
(radio, accessory power outlet, 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 tothe “ON ”position.
CAUTION
Do not turn the ignition switch to the “ START ”position while the engine
is running.
! For vehicle with immobilizer
If your registered key fails to start the
engine, pull out the key once (the security
indicator light will blink), and then insert
the key in the ignition switch and turn it tothe “START ”position and again try to start the engine.
NOTE
The engine may not start in the follow-
ing cases:
. The key grip is touching another key
or a metallic key holder.

contact your nearest SUBARU dealer
immediately.
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
& 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 the engine has started.
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
unnecessary 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 transmis-
sion control system is not working prop-
erly. Contact your nearest SUBARU deal- er for service immediately.
& Rear differential oil
temperature warning
light (WRX-STI)
CAUTION
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 thepowertrain.
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 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 en-
ough 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 ”
position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, 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. Instruments and controls

Mirrors
Always check that the inside and outside
mirrors are properly adjusted before you
start driving. &Inside mirror
The inside mirror has a day and night
position. Pull the tab at the bottom of the
mirror toward you for the night position.
Push it away for the day position. The
night position reduces glare from head-lights. !
Auto-dimming mirror/compass (ifequipped)
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The auto-dimming mirror has an anti-glare
feature which automatically reduces glare
coming from headlights of vehicles behind
you. It also contains a built-in compass. . By pressing and releasing the left
button, the automatic dimming function is
toggled on or off. When the automatic
dimming function is on, the auto dimming
indicator light (green) located to the right
of the button will illuminate. . By pressing and releasing the right
button, the compass display is toggled on
or off. When the compass is on, an illuminated compass reading will appear
in the lower part of the mirror.
Even with the mirror in anti-glare mode,
the mirror surface turns bright if the
transmission is shifted into reverse. This
is to ensure good rearward visibility duringreversing. !
Photosensors
The mirror has a photosensor attached on
both the front and back sides. If the glare
from the headlights of vehicles behind you
strikes the mirror, these sensors detect it
and make the reflection surface of the
mirror dimmer to help prevent you from
being blinded. For this reason, use care
not to cover the sensors with stickers, or
other similar items. Periodically wipe the
sensors clean using a piece of dry soft

the tank whenever the low fuel warning
light comes on. Engine misfires as a
result of an empty tank could cause
damage to the engine.
CAUTION
. Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
. Make sure that the cap is tigh-
tened until it clicks to prevent
fuel spillage in the event of anaccident.
. Do not let fuel spill on the exterior
surfaces of the vehicle.
Fuels may cause paint damage,
which is not covered under the
SUBARU Limited Warranty.
. Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting, and your fuel
tank and emission control sys-
tem might be damaged. State emission testing (U.S. only)
At state inspection time, remember to
tell your inspection or service station in
advance not to place your Subaru AWD
vehicle on a two-wheel dynamometer.
Otherwise, serious transmission da-
mage will result.
Some states have started using dynam-
ometers in their state inspection programs
in order to meet their obligation under
federal law to implement stricter vehicle
emission standards to reduce air pollution
from vehicles. A dynamometer is a tread-
mill or roller-like testing 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 ”vehicle emission
inspection test. Normally, a portion of the
basic emission test consists of an emis-
sion 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 emission testing
programs have
EXEMPTEDSubaru AWD
vehicles from the portion of the testing
program that involves a two-wheel dy-
namometer.
There are some states that use four-wheel
dynamometers in their testing programs.
When properly used, that equipment will
not damage an AWD Subaru vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
WARNING
Testing of an All-Wheel Drive vehicle
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby. Starting and operating

Starting the engine
CAUTION
Do not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.
& Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and ac- cessories.
3. Press the clutch pedal to the floor and
shift the shift lever into neutral. Hold the
clutch pedal to the floor while starting theengine.
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 accelera-
tor 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 “START ”position
while depressing 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 ”
position and wait for at least 10
seconds. Then fully depress the accel-
erator pedal 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 ”
position. 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,
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 auto- matically lowers the idle speed as the
engine warms up.
NOTE
The engine may be difficult to start
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty 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 ve- hicle
1. Apply the parking brake.
2. Turn off unnecessary lights and ac- cessories.
3. Shift the selector lever to the “P ”or “N ”
position (preferably “P ”position).
The starter motor will only operate when
the selector lever 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 syn-
chromeshed, 6-forward-speed and 1-re-
verse-speed transmission.
The shift pattern is shown on the shift
lever knob.
WARNING
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 position.
Engine braking has no effect in
either of these conditions and the
risk of an accident is consequentlyincreased.
& Selecting reverse gear
1) Slider
You must raise the slider and hold it in that
position before 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.
CAUTION
Shift into reverse ONLY when the
vehicle has completely stopped. It
may cause damage to the transmis-
sion to try shifting into reverse when
the vehicle is moving.
& Shifting speeds
! Recommended shifting speeds
The best compromise between fuel econ-
omy and vehicle performance during
normal driving is ensured by shifting up
at the speeds listed in the following table.
Shift up mph (km/h)
1st to 2nd 15 (24)
2nd to 3rd 25 (40) 3rd to 4th 40 (64)
