for repair. &
Seatbelt warning light
and chime
Your vehicle is equipped with a seatbelt
warning device at the driver ’s seat, as
required by current safety standards.
There is a seatbelt warning light in the
combination meter.
If the driver has not yet fastened the
seatbelt 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 remain
lit for 15 seconds. If the driver ’s seatbelt is
still not fastened even 15 seconds later
(21 seconds after turning ON the ignition
switch), the warning lights will alternate
between flashing and steady illumination
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
after fastening, the seatbelt warning
device operates as follows according
to the vehicle speed.
.At speeds lower than approxi-
mately 9 mph (15 km/h)
The warning light will alternate
between flashing and steady illumi-
nation 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
between flashing and steady illumi-
nation 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. When the ignition switch is
turned ON next time, however, the
complete sequence of the warning
operation resumes. For further details
about canceling the warning operation,
please contact your SUBARU dealer. & SRS airbag system

&CHECK ENGINE warn-
ing light/Malfunction in-
dicator lamp
CAUTION
If the CHECK ENGINE light comes
on while you are driving, have your
vehicle checked/repaired by your
SUBARU dealer as soon as possi-
ble. Continued vehicle operation
without having the emission control
system checked and repaired as
necessary could cause serious da-
mage, which may not be covered by
your vehicle ’s warranty.
If this light comes on steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential
problem somewhere in the emission con-
trol system. ! If the light comes on steadily:
If the light comes on steadily while driving
or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately. NOTE
This light also comes on 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 lamp coming on
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
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, 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 thefollowing. . Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble.. Stop towing a trailer as soon as
possible. The CHECK ENGINE warning light may
stop blinking and come on steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately. &
Charge warning light
If this light comes on when the engine is
running, it may indicate that the charging
system is not working properly.
If the light comes on while driving or does
not go out 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 on, contact
your nearest SUBARU dealer immedi-
ately. &Oil pressure warning light
If this light comes on 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 comes on while driving or does
not go out 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 remains on,

contact your nearest SUBARU dealer
immediately.
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
& AT OIL TEMPerature
warning light (AT vehi- cles)
The AT oil temperature warning light
comes on when the ignition switch is
turned to the “ON ”position and goes out
after the engine has started.
If this light comes on when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light comes on while driving, it is
unnecessary to stop the vehicle, but avoid
driving up steep grades or in stop and go
traffic. ! Automatic transmission control
system warning
If the light flashes after the engine starts, it
may indicate that the automatic transmis-
sion control system is not working prop-
erly. Contact your nearest SUBARU deal- er for service immediately.
& Rear differential oil
temperature warning
light (WRX-STI)
CAUTION
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
comes on. Continued driving with
this light on can damage the rear
differential and other parts of thepowertrain.
If this light comes on 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
adopts its minimum ratio.
If the light comes on while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place.
Park the vehicle for several minutes. After
the light goes out, you can start driving.
If the light does not go out, 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 come on. It is
advisable to have the rear differential
oil replaced as soon as possible. & ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ”
position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, the ABS system may not
work properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. Instruments and controls

Engine overheating
WARNING
Never attempt to remove the radia-
tor 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
coolant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe place. & If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down. & If no steam is coming from
the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays at the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the
“LOW ”
mark, add coolant up to the “FULL ”mark.
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. Towing
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following
procedures for safety.
WARNING
Never tow AWD vehicles (both AT
and MT) with the front wheels raised
off the ground while the rear wheels
are on the ground, or with the rear
wheels raised off the ground while
the front wheels are on the ground.
This will cause the vehicle to spin
away due to the operation or dete-
rioration of the center differential. In case of emergency

11-12Maintenance and service
&Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or
used for heavy-duty applications such as
towing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM (or SL): SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
& Synthetic oil
You can use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner ’s Manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule. Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
CAUTION
. The cooling system has been
filled at the factory with a high
quality, corrosi on-inhibiting,
year-around coolant which pro-
vides protection against freezing
down to 33 8F( 36 8C). For add-
ing, use genuine SUBARU cool-
ant or an equivalent: a mixture of
50% soft water (or clear and
drinkable water) and 50% phos-
phate or non-amine type coolant.
Use of improper coolants may
result in corrosion in the cooling
system. It is important to main-
tain protection against freezing
and corrosion, even if freezing temperatures are not expected.
Never mix different kinds of cool-ant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con- nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Check the fuse and replace it
if necessary. If the fuse is not blown, have
the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.
Page 289 of 364
&Engine coolant
! Checking the coolant level
1) “FULL ”level mark
2) “LOW ”level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the “ LOW ”level mark, add coolant up to the
“ FULL ”level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.
3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
CAUTION
. Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface. !
Changing the coolant
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant isreplaced.
Change the engine coolant and add

vehicle weight and dividing by two. . Vehicle normal load on a tire
Load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal occu-
pant weight and dividing by two. & Tire care –maintenance and
safety practices
. Check on a daily basis that the tires
are free from serious damage, nails,
and stones. At the same time, check the tires for abnormal wear. .
Inspect the tire tread regularly and
replace the tires before their tread
wear indicators become visible. When
a tire ’s tread wear indicator becomes
visible, the tire is worn beyond the
acceptable limit and must be replaced
immediately. With a tire in this condi-
tion, driving at even low speeds in wet
weather can cause the vehicle to
hydroplane. Possible resulting loss
of vehicle control can lead to an
accident. . To maximize the life of each tire
and ensure that the tires wear uni-
formly, it is best to rotate the tires
every 7,500 miles (12,500 km). Rotat-
ing the tires involves switching the
front and rear tires on the right-hand
side of the vehicle and similarly
switching the front and rear tires on
the left-hand side of the vehicle.
(Each tire must be kept on its original
side of the vehicle.) Replace any
damaged or unevenly worn tires at
the time of rotation. After tire rotation,
adjust the tire pressures and make
sure the wheel nuts are correctly
tightened. A tightening torque specifi-
