To change the REV indicator settings,
perform the procedures described in “ REV

Warning and indicator lights Several of the warning and indicator lights
illuminate when the ignition switch is
initially turned 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
seatbelt.)
: Front passenger ’ s seatbelt warning
light
(The seatbelt warning light turns off
only when the front seat passenger
fastens the seatbelt.)

Instruments and controls/Warning and indicator lights
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
location as soon as possible. Con-
tinuing to drive with this light illumi-
nated may damage the rear differ- ential and other parts of the power-
train.
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.3-18

trol Center Differential (C.DIFF/DCCD)

! Driver ’ s control center dif-
ferential auto [+] indicator
(STI)
When the AUTO [+] mode is set, the
AUTO [+] indicator appears.
For details, refer to “ Driver ’ sControl
Center Differential (C.DIFF/DCCD) (STI) ”
F 7-19.
! Driver ’ s control center dif-
ferential auto [ − ] indicator
(STI)
When the AUTO [ − ] mode is set, the
AUTO [ − ] indicator appears.
For details, refer to “ Driver ’ sControl
Center Differential (C.DIFF/DCCD) (STI) ”
F 7-19. & Driver ’ s control center differ-
ential indicator and warning
(STI) ! Indicator
When you select the manual mode of the
driver ’ s control center differential, the
initial limited slip differential (LSD) torque
that is currently selected for the center
differential is indicated by the illumination
of these indicator. ! Warning indicator
All the indicators 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 (C.
DIFF/DCCD) (STI) ” F 7-19.
If a malfunction occurs in the vehicle (for
example, when the rear differential oil
temperature warning light illuminates), all
of the indicators may disappear and the
setting value for the initial limited slip
differential (LSD) torque of the driver ’ s
control center differential (C.DIFF/DCCD)
may be cancelled. However, it does not
indicate a malfunction of the C.DIFF/
DCCD itself.3-36

Climate control/Operating tips for heater and air conditioner
& Efficient cooling after parking
in direct sunlightAfter parking in direct sunlight, drive with
the windows open for a few minutes to
allow outside air to circulate into the
heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency.
& Lubrication oil circulation in
the refrigerant circuitOperate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.
& Checking air conditioning
system before summer sea-
sonCheck the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer. & Cooling and dehumidifying in
high humidity and low tem-
perature weather conditions Under certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate
any problem with the air conditioning
system.
& Air conditioner compressor
shut-off when engine is
heavily loaded To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving up a steep
incline. & Refrigerant for your climate
control system
1) Air conditioner label
Your air conditioner uses ozone friendly
refrigerant HFC134a (as shown on the air
conditioner label). Therefore, the method
of adding, changing or checking the
refrigerant is different from the method
for CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty.4-10

CAUTIONTrapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
NOTE Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops. Starting and stopping the
engine (models without
push-button start system) & Starting engine CAUTIONDo not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.
NOTE It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
controlled throttle ’ s self-diagnosis
function. To overcome it, keep the
ignition switch in the “ ON ” position
for approximately 10 seconds before
starting the engine. ! General precautions when starting
engine
WARNING. Never start the engine from out-
side the vehicle. It may result in
an accident.
. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
. Do not start the engine near dry
foliage, paper, or other flam-
mable substances. The exhaust
pipe and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
. If the engine is stopped during
driving, the catalyst may over-
heat and burn.Starting and operating/Starting and stopping the engine (models without push – button start system)
