NOTEThis light also illuminates when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator light illuminating
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering with
the sealing of the cap. Tightening the cap
will not make the CHECK ENGINE warn-
ing light/malfunction indicator light turn off
immediately. It may take several driving
trips. If the light does not turn off, take your
vehicle to your authorized SUBARU dealer
immediately.
!If the light is blinking
If the light is blinking while driving, an
engine misfire condition has been de-
tected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should do the
following.
.Reduce vehicle speed.
.Avoid hard acceleration.
.Avoid steep uphill grades.
.Reduce the amount of cargo, if possi-
ble.The CHECK ENGINE warning light may
stop blinking and illuminate steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately.
&Charge warning lightIf this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good
condition but the light remains illuminated,
contact your nearest SUBARU dealer
immediately.&Oil pressure warning
lightIf this light illuminates when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is
at the proper level but the light remainsilluminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to
“Engine oil”F11-13.
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.&Engine low oil level
warning indicator
(except STI)This indicator appears when the engine oil
level decreases to the lower limit.
If the engine low oil level warning indicator
appears while driving, park the vehicle in a
safe and level location, and then check the
engine oil level. When the engine oil level
is not within the normal range, refill with
engine oil. Refer to“Engine oil”F11-13.
If the warning indicator does not disappear
after refilling the engine oil, or the warning
indicator appears even though the engine
oil level is within the normal range, have
the vehicle checked by a SUBARU dealer.

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.

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

gine&General precautions when
starting/stopping engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
.Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can cre-
ate a fire hazard at high tempera-
tures.
.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.
CAUTION
.Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
.When starting the engine, be sureto sit in the driver’s seat (except
when using the remote engine
start system).
NOTE.Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
.Until the engine is warmed up suffi-
ciently, the engine speed is maintained
high. The engine speed will gradually
drop as the engine warms up.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly such
as a rapid start-up and a rapid accel-
eration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.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

Engine overheating
WARNING
Never attempt to remove the radiator
cap until the engine has been shut
off and has fully cooled down. When
the engine is hot, the coolant is
under pressure. Removing the cap
while the engine is still hot could
release a spray of boiling hot cool-
ant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.&If steam is coming from the
engine compartment.Turn off the engine and get everyone
away from the vehicle until it cools down.
.Contact an authorized SUBARU deal-
er.
&If no steam is coming from the
engine compartment1. Keep the engine running at idling
speed.
2. Open the engine hood to ventilate the
engine compartment. Refer to“Engine
hood”F11-9.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.Temperature gauge
1) Normal operating rangeIf temperature gauge stays in the over-
heated zone, turn off the engine. Refer to
“Temperature gauge”F3-11.4. After the engine has fully cooled down,
check the coolant level in the reserve tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
NOTEFor details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-17.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank. Then
remove the radiator cap and fill the radiator
with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
