Safety precautions when
driving&Seatbelt and SRS airbag
WARNING
.All persons in the vehicle must
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent.
.To obtain maximum protection in
the event of an accident, the
driver and all passengers must
always wear seatbelts when in
the vehicle. The SRS (Supple-
mental Restraint System) airbag
does not do away with the need to
fasten seatbelts. In combination
with the seatbelts, it offers the
best combined protection in case
of a serious accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.

NOTEEven if the REV alarm system is not set,
the REV indicator light will flash when-
ever the engine speed enters the red
zone of the tachometer.
To change the REV indicator settings,
perform the procedures described in
“REV settings (STI)”F3-43.
Warning and indicator lightsSeveral of the warning and indicator lights
illuminate when you initially turn the igni-
tion switch to the“ON”position. This
permits checking 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 then turn off after several
seconds or after the engine has started.: Seatbelt warning light
(The seatbelt warning light turns off
only when the driver fastens the seat-
belt.): Front passenger’s seatbelt warning
light

NOTE.After replacing or adding the engine
oil, if the engine oil level is within the
normal range when restarting the en-
gine on a level surface, the warning
indicator will be off.
.The warning indicator may appear
temporarily in the following conditions
because a low oil level may be detected
as a result of significant oil movement
in the engine.
–when the vehicle is considerably
inclined on an uphill or steep slope
–when the vehicle has continu-
ously accelerated and decelerated
–when the vehicle is continuously
turned
–when the vehicle is driven on a
road that alternates continuously
between uphill and downhill&Windshield washer
fluid warning indicatorThis indicator appears when the fluid level
in the windshield washer fluid tank de-
creases to the lower limit (approximately
1.1 US qt, 1.0 liter, 0.9 Imp qt).
&AT OIL TEMP warning
light (CVT models)If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, im-
mediately stop the vehicle in a safe place
and let the engine idle until the warning
light turns off.
!Transmission control system warn-
ing
If the“AT OIL TEMP”warning light flashes
after the engine has started, it may indicate
that the transmission control system is not
working properly. Contact your nearest
SUBARU dealer for service immediately.&Rear differential oil
temperature warning
light (STI)
CAUTION
If the R.DIFF TEMP warning light
illuminates, reduce vehicle speed
and stop the vehicle in a safe loca-
tion as soon as possible. Continuing
to drive with this light illuminated
may 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 in the
nearest safe location. 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.

switch is“ON”. When it appears, it indi-
cates that the driver’s control center
differential is set to the auto mode. It
disappears when the driver’s control cen-
ter differential is set to the manual mode.

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 (C.
DIFF/DCCD) (STI)”F7-18.
If a malfunction occurs in the vehicle (for
example, when the rear differential oil
becomes hot), all of the indicators may
disappear. In this case, the setting value
for the initial limited slip differential (LSD)
torque of the driver’s control center differ-
ential (C.DIFF/DCCD) will be cancelled.
However, it does not indicate a malfunction
of the C.DIFF/DCCD itself.
&REV indicator light (STI)This indicator light illuminates when the
engine speed reaches the level that was
previously set. This indicator light also
flashes when the tachometer needle en-
ters the red zone. For details, refer to“REV
