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.
The key can be turned from “Acc ”to
“ LOCK ”only when the key is pushed in
while turning it. Instruments and controls

The key is near or touching another
transmitter. & Key reminder chime
The reminder chime sounds when the driver ’s door is opened and the ignition
switch is in the “LOCK ”or “Acc ”position.
The chime stops under the followingconditions. . when the ignition switch is turned to the
“ ON ”position
. when the key is removed from the
ignition switch. when the driver ’s door is closed
& Ignition switch light
For easy access to the ignition switch in
the dark, the ignition switch light illumi-
nates when the driver ’s door is opened or
when the driver ’s door is unlocked using
the remote keyless entry transmitter.
The light remains illuminated for several
tens of seconds and then gradually turns
off under the following conditions. . when the driver ’s door is closed

NOTE
If the connection between the combina-
tion meter and battery is broken for any
reason such as vehicle maintenance or
fuse replacement, the data recorded on
the trip meter will be lost. &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. This may cause severe da-
mage to the engine. &
Fuel gauge
1) Low fuel warning light
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 will light up and indicate the
amount of fuel remaining in the tank.
If, while the fuel gauge is indicating the
amount of fuel remaining in the tank, you
(a) do not press the trip knob for 10
seconds or (b) open and close the driver ’s door, the fuel gauge indication will turn off.
NOTE
You will see the “”sign in the fuel
gauge meter.

&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.
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 when 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 “Engine overheating ”F9-
12. REV indicator light and buz-
zer (STI)
The REV alarm system issues a warning
using the REV indicator light (and a
buzzer if additionally selected) when the
engine speed reaches a level previously
set using the trip knob.
If you press the trip knob, the odometer/
trip meter will show the engine speed that
has already been set.

NOTE
Even if the REV alarm system is not set,
the REV indicator light will illuminate
whenever the engine speed enters thetachometer’s red zone.

board.
When the ignition switch is turned to the “ON ”position, both the ON and OFF
indicators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators turn
off for 2 seconds. After that, one of the
indicators illuminates depending on the
status of the front passenger ’s SRS frontal
airbag determined by the SUBARU ad-
vanced frontal airbag system monitoring.
If the front passenger ’s SRS frontal airbag
is activated, the passenger ’s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain off.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’s frontal
airbag ON indicator will remain off while
the OFF indicator will illuminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain illuminated or off simulta-
neously even after the system check
period, the system is malfunctioning.
Contact your SUBARU dealer immedi-
ately for an inspection. &
CHECK ENGINE warn-
ing light/Malfunction in-
dicator light
CAUTION
If the CHECK ENGINE light illumi-
nates while you are driving, have
your vehicle checked/repaired by
your SUBARU dealer as soon as
possible. Continued vehicle opera-
tion without having the emission
control system checked and re-
paired as necessary could cause
serious damage, which may not be
covered by your vehicle ’s warranty.
If this light illuminates steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential
problem somewhere in the emission con-
trol system. ! If the light illuminates steadily
If the light illuminates steadily while driving
or does not turn off after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately. NOTE
This light also illuminates when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator light illuminating
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not turn off, take your vehicle to your
authorized SUBARU dealer immediately. !
If the light is blinking
If the light is blinking while driving, an
engine misfire condition has been de-
tected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should do thefollowing. . Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble. Instruments and controls
