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.
300564
300565
300566
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.

3-4 Instruments and controls
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 ” po-
sition, turn the steering wheel slightly
to the left and right as you turn the ig-
nition switch.
If the key is attached to a keyholder
or to a large bunch of other keys, cen-
trifugal force may act on it as the vehi-
cle moves, resulting in unwanted turn-
ing of the ignition switch. Also, if a
large keyholder is attached to the key,
your knees or hands may accidentally
touch it in a way that turns the ignition switch.
ACC
In this position the electrical accessories
(radio, cigarette 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.
For vehicle with immobilizer
If your registered key fails to start the en-
gine, pull out the key once (the security in-
dicator light will blink), and then insert the
key in the ignition switch and turn it to the“ 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.
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. Children could
operate the power windows, the
sunroof or other controls or even
make the vehicle move.
Do not turn the ignition switch to the “ START ” position while the engine
is running.

Odometer/Trip meter
1) Trip meter
2) Odometer
This meter displays the odometer and two
trip meters when the ignition switch is in
the “LOCK ”, “ACC ” or “ON ” position.
If you press the trip knob when the ignition
switch is in the “LOCK ” position, the
odometer/trip meter will light up. It is pos-
sible switch between the A trip meter and
B trip meter indications while the odome-
ter/trip meter is lit up. If you do not press
the trip knob within 10 seconds of illumina-
tion of the odometer/trip meter, the odom-
eter/trip meter will go off.
Odometer
The odometer shows the total distance that the vehicle has been driven.
Double trip meter
The trip meter shows the distance that the
vehicle has been driven since you last set
it to zero.
To change the mode indication, briefly
push the knob.
Each press of the knob changes the func-
tion alternately.
To set the trip meter to zero, select the A
trip or B trip meter by pushing the knob
and keep the knob pushed for more than
2 seconds.
NOTE
If the connection between the combi-
nation meter and battery is broken for
any reason such as vehicle mainte-
nance or fuse replacement, the data re-
corded on the trip meter will be lost.
Tachometer
The tachometer shows the engine speed
in thousands of revolutions per minute.

To ensure safety, do not attempt to
change the function of the indicator
during driving, as an accident could
result.
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.

3-8 Instruments and controls
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 brak-
ing, turning or acceleration due to fuel lev-
el movement in the tank.
NOTE
You will see the “ ” sign in the fuel
gauge meter.
This indicates that the fuel filler door
(lid) is located on the right side of the
vehicle.
Low fuel warning light
The low fuel warning light comes on when
the tank is nearly empty [Approximately
2.3 US gal (9.0 liters, 1.9 Imp 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 Imp gal).
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 ac-
cordance with the outside temperature
and driving conditions.
1300615300310
Promptly put fuel in the tank when-
ever the low fuel warning light
comes on. Engine misfires as a re-
sult of an empty tank could cause
damage to the engine.

– CONTINUED –
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range. En-
gine 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.
Outside temperature indica-
tor
1) U.S.-spec. models
2) Canada-spec. models
The outside temperature indicator shows
the outside temperature in a range from –
22 to 122 F ( –30 to 50 C).
The indicator can give a false reading un-
der any of the following conditions:
When there is too much sun.
During idling; while running at low
speeds in a traffic jam; when the engine is
restarted immediately following a shut-
down.
When the actual outside temperature
falls outside the specified indicator range.
REV indicator light and buzz-
er (WRX-STI)
The REV alarm system issues a warning
using the REV indicator light (and a buzz-
er if additionally selected) when the en-
gine speed reaches a level previously set
using the REV setting knob.
If you press the trip knob when the ignition
switch is in the “LOCK ” position, the out-
side temperature indicator 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 come
on whenever the engine speed enters
the tachometer ’s red zone.
If the pointer exceeds the normal
operating range, safely stop the ve-
hicle as soon as possible.

Setting the alarm-level en-
gine speed
1. Turn the REV setting knob clockwise or
counterclockwise, then release it and let it
return to its initial position. The buzzer will
sound. The REV alarm system is now
ready to be set.
2. Turn the REV setting knob to select the
desired alarm-level engine speed.
At this time, the outside temperature indi-
cator will show the engine-speed setting.
Counterclockwise ( –) for less than 0.5
second: Speed setting changes down-
ward by 100 rpm.
Clockwise (+) for less than 0.5 sec-
ond: Speed setting changes upward by
100 rpm.
Counterclockwise ( –) for 0.5 second or longer: Speed setting changes down-
ward by 1,000 rpm.
Clockwise (+) for 0.5 second or long-
er: Speed setting changes upward by
1,000 rpm.
The speed setting will stop changing if it
reaches 0 rpm or the maximum engine
speed.

The alarm-level engine speed can be set
(in 100 rpm steps) within a range from
2,000 to 7,500 rpm.
The indicator shows the setting as follows:
Approximately three seconds after you
stop turning the knob, the REV alarm sys-
tem will automatically enter its next setting
mode (step 3 below), in which you can ac-
tivate or deactivate the buzzer. 3. Activate or deactivate the buzzer as
desired using the REV setting knob.Turn the knob clockwise (+) to acti-
vate the buzzer. The indicator will show “ ON ”, and the buzzer will sound three
times. With the buzzer activated, en-
gine-speed warnings are given by both
the REV indicator light and the buzzer.
Turn the knob counterclockwise ( –) to
deactivate the buzzer. The indicator will
show “– –” , and the buzzer will not
sound. With the buzzer deactivated, en-
gine-speed warnings are given only by
the REV indicator light.
Approximately three seconds after you
stop turning the knob, the buzzer will
sound once to indicate the end of the set-
ting procedure. The indicator will return to
showing the outside temperature.
Also, the tachometer needle will return to
approximately “0 ”.
NOTE
The REV alarm system does not op-
erate while settings are being entered.
The speed-setting mode terminates
if 0 rpm is selected.
The speed-setting mode is canceled
if the ignition switch is turned to OFF or
the vehicle starts moving before the
setting procedure is finished.
