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.

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.
See the
“In case of emergency ” in
chapter 9.

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.
Speed setting is impossible when

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.
Fuel gauge
1) Low fuel warning light
The fuel gauge shows the approximate
amount of fuel remaining in the tank.
The gauge does not return to “E ” even
though the ignition switch is in the “ACC ”
or “LOCK ” position.
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 “FUEL DOOR ”
sign near the fuel gauge.
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).
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.

corresponding system.
Consult your authorized SUBARU dealer
for repair.
Seatbelt warning light
and chime
Your vehicle is equipped with a seatbelt
warning device at the driver
’s seat, as re-
quired by current safety standards. There
is a seatbelt warning light in the combina-
tion meter.
If the driver has not yet fastened the seat-
belt when the ignition switch is turned to
the “ON ” position, the seatbelt warning
light will flash for 6 seconds, to warn that
the seatbelt is unfastened. If the driver ’s
seatbelt is not fastened, a chime will also
sound simultaneously.
If the driver ’s seatbelt is still not fastened
6 seconds later, the warning light will re-
main lit for 15 seconds. If the driver ’s seat-
belt is still not fastened even 15 seconds
later (21 seconds after turning ON the ig-
nition switch), the warning lights will alter-
nate between flashing and steady illumi-
nation at 15-second intervals, and the
chime will sound while the warning light is
flashing.
Alternate flashing and steady illumination
of the warning lights and sounding of the chime will continue until the driver fastens
the seatbelt.
NOTE
If the driver unfastens the seatbelt af-
ter fastening, the seatbelt warning de-
vice operates as follows according to
the vehicle speed.
At speeds lower than approximate-
ly 9 mph (15 km/h)
The warning light will alternate be-
tween flashing and steady illumina-
tion at 15-second intervals. The
chime will not sound.
At speeds higher than approxi-
mately 9 mph (15 km/h)
The warning light will alternate be-
tween flashing and steady illumina-
tion at 15-second intervals and the
chime will sound while the warning
light is flashing.
It is possible to cancel the warning
operation that follows the 6-second
warning after turning ON the ignition
switch by unfastening and refastening
the driver ’s seatbelt. When the ignition
switch is turned ON next time, howev-
er, the complete sequence of the warn-
ing operation resumes. For further de-
tails about canceling the warning oper-
ation, please contact your SUBARU
dealer.

SRS airbag system
warning light
When the ignition switch is turned to the “ON ” position, the SRS airbag system
warning light will come on for approxi-
mately six seconds and go out. This
shows the SRS airbag and SRS side air-
bag (if equipped) and seatbelt pretension-
ers are in normal operation.
Front passenger ’s frontal air-
bag ON and OFF indicators
: Front passenger ’s frontal airbag
ON indicator
: Front passenger ’s frontal airbag
OFF indicator
The front passenger ’s frontal airbag ON
and OFF indicators show you the status of
the front passenger ’s SRS frontal airbag.
The indicators are located next to the
clock in the center portion of the dash-
board. When the ignition switch is turned to the“
ON ” position, both the ON and OFF indi-
cators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators ex-
tinguish 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
advanced frontal airbag system monitor-
ing.
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 extinguished.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’s frontal air-
bag ON indicator will remain extinguished
while the OFF indicator will illuminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain lit or extinguished simulta-
neously even after the system check peri-
od, the system is faulty. Contact your
SUBARU dealer immediately for an in-
spection.
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase the risk of injury.
