Immobilizer
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle’s immobilizer system can
be used to operate your vehicle. Even if
an unregistered key fits into the ignition
switch and can be turned to the “START ”
position, the engine will automatically stop
after several seconds.
Each immobilizer key contains a trans-
ponder in which the key ’s ID code is
stored. When a key is inserted into the
ignition switch and turned to the “ON ”
position, the transponder transmits thekey ’s ID code to the immobilizer system ’s
receiver. If the transmitted ID code
matches the ID code registered in the
immobilizer system, the system allows the
engine to be started. Since the ID code is
transmitted and acted upon almost in-
stantly, the immobilizer system does not
impede normal starting of the engine.
If the engine fails to start, pull out the key
once before trying again. (Refer to the“ Ignition switch ”section [chapter 3].)
This device complies with Part 15 of

& Security indicator light
Vehicle with SI-DRIVE
Vehicle without SI-DRIVE
The security indicator light deters potential
thieves by indicating that the vehicle is equipped with an immobilizer system. It
begins flashing approximately 60 seconds
after the ignition switch is turned from the“
ON ”position to the “Acc ”or “LOCK ”
position or immediately after the key is
pulled out.
If the security indicator light does not flash,
the immobilizer system may be faulty. If
this occurs, contact your SUBARU dealer
as soon as possible.
In case an unauthorized key is used (e.g.
an imitation key), the security indicator
light comes on.
NOTE
Even if the security indicator light
flashes irregularly or its fuse blows
(the light does not flash if its fuse is
blown), the immobilizer system will
function normally. & Key replacement
Your key number plate and security ID
plate will be required if you ever need a
replacement key made. Any new key must
be registered for use with your vehicle ’s
immobilizer system before it can be used.
Up to four keys can be registered for use
with one vehicle.
For security, all the keys registered with
your vehicle ’s immobilizer system will have their ID codes erased and re-
registered when a new key is made.
Therefore, all of your vehicle
’s keys must
be presented when a new key is regis-
tered. Any key that is not re-registered
when a new key is made cannot be used
after the other keys are re-registered. For
information on replacement keys and on
the registration of keys with your immo-
bilizer system, contact your SUBARU
dealer.
NOTE
A vehicle that is equipped with the
remote engine start system as the
dealer option can register up to three
keys for use with one vehicle.

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 sunroof
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 were 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. Instruments and controls
3-3
– CONTINUED –

3-4Instruments and controls
!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
CAUTION
Do not turn the ignition switch to the “ START ”position while the engine
is running.
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.
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.
. The key is near another key that
contains an immobilizer transponder. . The key is near or touching another
transmitter.

ignition switch to start the engine. This
is not an indication of a problem. &Speedometer
The speedometer shows the vehicle speed. & Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.
CAUTION
Do not operate the engine with the
pointer of the tachometer in the red
zone. In this range, fuel injection will
be cut by the engine control module
to protect the engine from overrev-
ving. The engine will resume run-
ning normally after the engine speed
is reduced below the red zone.
NOTE (3.0-liter models only)
To protect the engine while the “P ” or
“ N ” position is selected, the engine is
controlled such that the engine speed
does not become too high even if the
accelerator pedal is fully depressed. &
Fuel gauge
The fuel gauge shows the approximate
amount of fuel remaining in the tank.
When the ignition switch is in the “LOCK ”
or “Acc ”position, the fuel gauge shows “E ”
even if the fuel tank contains fuel.
The gauge may move slightly during
braking, turning or acceleration due to fuel
level movement in the tank.
If you press the trip knob while the ignition
switch is in the “LOCK ”or “Acc ”position,
the fuel gauge ’s dial and needle will light
up and the needle will indicate the amount
of fuel remaining in the tank.
If, while the fuel gauge needle is indicating
the amount of fuel remaining in the tank,
you (a) do not press the trip knob for 5
seconds or (b) open and close the driver ’s door, the fuel gauge needle will drop to the“
E ”position and the dial and needle will go
off.
The dial of the fuel gauge flashes five
times when the amount of remaining fuel
reaches 2.6 US gal (10 liters, 2.2 lmp gal).
If you turn the ignition switch to the “ LOCK ”position and back to the “ON ”
position, the dial will again flash five times.

NOTE
You will see the“”sign in the fuel
gauge.
This indicates that the fuel filler door
(lid) is located on the right side of thevehicle. !
Low fuel warning light1) Low fuel warning light
The low fuel warning light comes on when
the tank is nearly empty [Approximately
2.6 US gal (10 liters, 2.2 lmp gal)].
It only operates when the ignition switch is
in the “ON ”position.
NOTE
This light does not go out unless the
tank is replenished up to an internal
fuel quantity of approximately 4.0 US
gal (15 liters, 3.3 lmp gal).
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
comes on. Engine misfires as a
result of an empty tank could cause
damage to the engine.
& Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions. Instruments and controls
3-7
– CONTINUED –

3-8Instruments and controls
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range.
And high revving operation while the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “In case of emergency ”in
chapter 9. &
ECO gauge
The ECO gauge shows the difference
between the average rate of fuel con-
sumption and the current rate of fuel
consumption. Using the average rate of
fuel consumption since the trip meter was
last reset, if the current rate of fuel
consumption is higher than the average
rate of fuel consumption, the indicator
needle points to the “+ ” or right side, and if
the current rate of fuel consumption is
lower than the average rate of fuel
consumption, the indicator needle points
to the “ ” or left side. When the indicator
needle is pointing to the “+ ” or right side, it
indicates fuel-efficient driving. NOTE .
The ECO gauge shows only an
approximate indication. . After resetting the trip meter, the
average rate of fuel consumption is not
shown until driving 0.6 mile (1 km).
Until that time, the ECO gauge does notoperate.
