to OFF, OFF to ON, or the vehicle starts
moving before the setting procedure isfinished..Setting the speed is impossible
when the vehicle is moving.. The set engine speed may differ
from the engine speed shown by the
tachometer. Use the engine speed
shown by the tachometer as a roughguide.. If the setting operation is performed
with the engine switch turned off, the
REV indicator light turns off and the
setting operation is aborted when you
have stopped the setting operation for
approximately 10 seconds. . If the setting operation is performed
with the engine switch turned off, the
REV indicator light turns off and the
setting operation is aborted when you
open and close the driver ’s door.
& Deactivating the REV alarm system
To deactivate the REV indicator light and
buzzer functions of the REV alarm system,
set the thousands place of the alarm-level
engine speed to “–”. Warning and indicator lights
Several of the warning and indicator lights
illuminate momentarily and then turn off
when the ignition switch is initially turned
to the
“ON ”position. This permits check-
ing the operation of the bulbs.
Apply the parking brake and turn the
ignition switch to the “ON ”position. For
the system check, the following lights
illuminate and turn off after several sec-
onds or after the engine has started:
: Seatbelt warning light (The seatbelt warning light turns off
only when the driver fastens theseatbelt.)
: Front passenger ’s seatbelt warning
light

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 and front
passenger ’s seat, as required by current
safety standards.
With the ignition switch turned to the “ON ”
position, this device reminds the driver
and front passenger to fasten their seat-
belts by illuminating the warning lights in
the locations indicated in the following
illustration and sounding a chime.
Driver ’s warning light (turbo models)
Driver ’s warning light (non-turbo models)
Front passenger ’s warning light
! Operation
If the driver and/or front passenger have/
has not yet fastened the seatbelt(s) when
the ignition switch is turned to the “ON ”
position, the seatbelt warning light(s) will
flash for 6 seconds, to warn that the
seatbelt(s) is/are unfastened. If the dri-ver ’s seatbelt is not fastened, a chime will
also sound simultaneously. NOTE . If the driver ’s and/or front passen-
ger ’s seatbelt(s) are/is still not fastened
6 seconds later, the seatbelt warning
device operates as follows according
to the vehicle speed.
–At speeds lower than approxi-
mately 9 mph (15 km/h)

is not working properly. Contact your
nearest SUBARU dealer for service im-
mediately. &Rear differential oil
temperature warning
light (STI)
CAUTION
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
illuminates. Continued driving with
this light illuminated can damage
the rear differential and other parts
of the powertrain.
If this light illuminates when the engine is
running, it may indicate that the rear
differential oil temperature is too hot.
At this time, the driver ’s control center
differential will automatically cancel the
current torque-distribution ratio setting and
adopt its minimum ratio.
If the light illuminates while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place. Park the vehicle for
several minutes. After the light turns off,
you can start driving.
If the light does not turn off, contact the
nearest SUBARU dealer for service. NOTE .
If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.. The rear differential oil will deterio-
rate if its temperature increases en-
ough for the rear differential oil tem-
perature warning light to illuminate. It is
advisable to have the rear differential
oil replaced as soon as possible. & Low tire pressure
warning light (U.S.-spec. models)
When the ignition switch is turned to the “ON ”position, the low tire pressure warn-
ing light will illuminate for approximately 2
seconds to check that the tire pressure
monitoring system (TPMS) is functioning
properly. If there is no problem and all tires
are properly inflated, the light will turn off.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for thosetires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle
’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver ’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, Instruments and controls

Driver ’s control center differ-
ential auto indicator light (STI)
This light functions while the ignition
switch is “ON ”. When illuminated, it
indicates that the driver ’s control center
differential is set to the auto mode. It turns
off when the driver ’s control center differ-
ential is set to the manual mode. For
details, refer to “Driver ’s Control Center
Differential (DCCD) (STI) ”F 7-18.

!Warning light
All the indicator lights will flash in the event
that the driver ’s control center differential
has a malfunction. Have the vehicle
inspected by your SUBARU dealer. For
details, refer to “Driver ’s Control Center
Differential (DCCD) (STI) ”F 7-18.
& REV indicator light (STI)
This light illuminates when the engine
speed reaches a level set by driver or
when the tachometer needle enters the
red zone. Clock
The time changes by 1 minute each time the
“+ ” button or “ ” button is pressed.
Pressing the “+ ” button moves the dis-
played time forward, while pressing the “ ”
button moves the displayed time back.
Pressing and holding either button
changes the displayed time continuously.
CAUTION
To ensure safety, do not attempt to
set the time while driving, as an
accident from inadequate attention
to the road could result.
NOTE
If the battery is disconnected, the time
will be erased. After reconnecting the
battery, set the correct time.
