fuel injection will be cut by the engine control
module to protect the engine from overrevving.
The engine will resume running normally after
the engine speed is reduced below the red
zone.
„ 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” po-
sition, 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.NOTE
You will see the “ ” sign in the fuel gauge
meter.
This indicates that the fuel filler door (lid) is locat-
ed on the right side of the vehicle. T
Low fuel warning light
The low fuel warning light comes on when the tank is
nearly empty [About 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 re-
plenished up to an internal fuel quantity of about
4.0 US gal (15 liters, 3.3 Imp gal).
Promptly put fuel in the tank whenever the low
fuel warning light comes on. If the engine mis-
fired as a result of an empty tank, resulting cat-
alytic converter damage could cause damage
to the turbocharger. „
Temperature gauge
1) Normal operating range
The temperature gauge shows engine coolant temper-
ature 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.

If the pointer exceeds the normal operating
range, safely stop the vehicle as soon as possi-
ble.
See the “In case of emergency” in chapter 9.
„ Outside temperature indicator
A) U.S.-spec. models
B) 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 under any of the
following conditions: y When there is too much sun.
y During idling; while running at low speeds in a traffic
jam; when the engine is restarted immediately follow-
ing a shutdown. y When the actual outside temperature falls outside
the specified indicator range.

REV indicator light and buzzer (WRX-
STi)
The REV alarm system issues a warning using the
REV indicator light (and a buzzer if additionally select-
ed) when the engine 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 outside 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. „
Setting the alarm-level engine speed
1. Turn the REV setting knob clockwise or counter-
clockwise, then release it and let it return to its initial
position. The buzzer will sound. The REV alarm sys-
tem 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 indicator will
show the engine-speed setting. yCounterclockwise (–) for less than 0.5 second:
Speed setting changes downward by 100 rpm.

Clockwise (+) for less than 0.5 second: Speed
setting changes upward by 100 rpm. y Counterclockwise (–) for 0.5 second or longer:
Speed setting changes downward by 1,000 rpm.y Clockwise (+) for 0.5 second or longer: 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 system will automatically en-
ter its next setting mode (step 3 below), in which you
can activate or deactivate the buzzer.
3. Activate or deactivate the buzzer as desired using
the REV setting knob. yTurn the knob clockwise (+) to activate the buzz-
er. 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 in-
dicator light and the buzzer.y
Turn the knob counterclockwise (–) to deactivate
the buzzer. The indicator will show “– –”, and the
buzzer will not sound. With the buzzer deactivated,
engine-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 setting procedure. The indicator will return
to showing the outside temperature.
Also, the tachometer needle will return to approxi- mately “0”.
NOTE y The REV alarm system does not operate while
settings are being entered. y The speed-setting mode terminates if 0 rpm is
selected. y The speed-setting mode is canceled if the igni-
tion switch is turned to OFF or the vehicle starts
moving before the setting procedure is finished.y Speed setting is impossible when the vehicle is
moving.y The set engine speed may differ from the engine
speed shown by the tachometer. Use the engine
speed shown by the tachometer as a rough guide.

To deactivate the REV alarm system’s REV indicator
light and buzzer functions, set the alarm-level engine
speed to 0 (zero) rpm.Meters and gauges (Except WRX-STi) „ Speedometer

Odometer
The odometer shows the total distance that the vehicle
has been driven. T Double trip meter
1) A trip meter
2) B 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 function alter-
nately. 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.
To ensure safety, do not attempt to change the
function of the indicator during driving, as an
accident could result.
NOTE
If the connection between the combination meter
and battery is broken for any reason such as vehi-
cle maintenance 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.
Do not operate the engine with the pointer of the tachometer in the red zone. In this range,
