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 seatbelts by
illuminating the warning lights in the loca-
tions indicated in the following illustration
and sounding a chime.

Driver’s warning light

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
illuminate for 6 seconds, to warn that the
seatbelt(s) is/are unfastened. If the driver’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)
The warning light(s) for unfastened

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.

If there is no passenger on the front
passenger’s seat, the seatbelt warning
device for the front passenger’s seat will
be deactivated. The front passenger’s
occupant detection system monitors
whether or not there is a passenger on
the front passenger’s seat.
Observe the following precautions. Failure
to do so may prevent the device from
functioning correctly or cause the device to
fail.
.

Do not install any accessory such as a

table or TV onto the seatback.
.

Do not store a heavy load in the

seatback pocket.
.

Do not allow the rear seat occupant to

place his/her hands or legs on the front
passenger’s seatback, or allow him/her to
pull the seatback.
.

Do not use front seats with their back-

ward-forward position and seatback not
being locked into place securely. If any of
them are not locked securely, adjust them

again. For adjusting procedure, refer to
“Front seats” F1-2.

If the seatbelt warning device for the front
passenger’s seat does not function cor-
rectly (e.g., it is activated even when the
front passenger’s seat is empty or it is
deactivated even when the front passen-
ger has not fastened his/her seatbelt), take
the following actions.
.

Ensure that no article is placed on the

seat other than a child restraint system and
its child occupant, although we strongly
recommend that all children sit in the rear
seat properly restrained.
.

Ensure that there is no article left in the

seatback pocket.
.

Ensure that the backward-forward po-

sition and seatback of front passenger’s
seat are locked into place securely by
moving the seat back and forth.

If still the seatbelt warning device for front
passenger’s seat does not function cor-
rectly after taking relevant corrective ac-
tions described above, immediately con-
tact your SUBARU dealer for an inspec-
tion.

is deactivated, the passenger’s frontal
airbag ON indicator will remain off while
the OFF indicator will illuminate.
With the ignition switch turned to the “ON”
position, if both the ON and OFF indicators
remain illuminated or off simultaneously
even after the system check period, the
system is malfunctioning. Contact your
SUBARU dealer immediately for an in-
spection.

CHECK ENGINE warn-
ing light/Malfunction in-
dicator light

CAUTION

If the CHECK ENGINE light illumi-
nates while you are driving, have
your vehicle checked/repaired by
your SUBARU dealer as soon as
possible. Continued vehicle opera-
tion without having the emission
control system checked and re-
paired as necessary could cause
serious damage, which may not be
covered by your vehicle’s warranty.

If this light illuminates steadily or blinks
while the engine is running, it may indicate
that there is at least one problem or
potential problem somewhere in the emis-
sion control system.

If the light illuminates steadily

If the light illuminates steadily while driving

NOTE

This 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 light

If 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
light

If 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 remains

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 indicator

This 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.

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 recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pres-
sure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires.)

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,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the

replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
Should the warning light illuminate steadily
after blinking for approximately one min-
ute, have the system inspected by your
nearest SUBARU dealer as soon as
possible.

WARNING

If this light does not illuminate
briefly after the ignition switch is
turned ON or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.

If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Other-
wise an accident involving serious
vehicle damage and serious perso-
nal injury could occur.

1) Keep driving straight ahead while

gradually reducing speed.

2) Slowly pull off the road to a safe

place.

If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, refer to “Flat tires” F9-4.

When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the Low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.

If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.

CAUTION

The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire

pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven to a vehicle speed of at
least 20 mph (32 km/h). After adjust-
ing the tire pressures, increase the
vehicle speed to at least 20 mph (32
km/h) to start the TPMS re-checking
of the tire inflation pressures. If the
tire pressures are now above the
severe low pressure threshold, the
low tire pressure warning light
should turn off a few minutes later.
Therefore, be sure to install the
specified size for the front and rear
tires.

ABS warning light

CAUTION

If any of the following conditions

occur, we recommend that you
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.

– The warning light does not

illuminate when the ignition
switch is turned to the “ON”
position.

– The warning light illuminates

when the ignition switch is
turned to the “ON” position,
but it does not turn off even
after starting the vehicle.

– The warning light illuminates

while driving.

When the warning light is on (and

the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper-
ate normally.

The ABS warning light illuminates together
with the brake system warning light if the
EBD system malfunctions. For further
details of the EBD system malfunction
warning, refer to “Brake system warning
light” F3-21.

NOTE

If the warning light behavior is as
described in the following conditions,
the ABS system may be considered
normal.
.

The warning light illuminates when

the ignition switch is turned to the “ON”
position and turns off approximately 2
seconds after the engine has started.
.

The warning light illuminates right

after the engine is started but turns off
immediately, remaining off.

When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction. When
the battery becomes fully charged, the
light will turn off.

Brake system
warning light

WARNING

Driving with the brake system

warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains illuminated,
have the brakes inspected by a
SUBARU dealer immediately.

If at all in doubt about whether the

brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.

For models with the electronic

parking brake: If the brake sys-
tem warning light illuminates, the
electronic parking brake system
may be malfunctioning. Immedi-
ately stop your vehicle in a safe
location, use tire stops under the
tires to prevent the vehicle from
m o v i n g a n d c o n t a c t y o u r
SUBARU dealer. For details, refer
to “Electronic parking brake
(models with electronic parking
brake system)” F7-43.

NOTE

For models with the electronic parking
brake:
.

Even if the brake system warning

light illuminates, if the warning light
behavior is as described in the follow-
ing examples, the electronic parking
brake system is not malfunctioning.

– The warning light turns off when
the electronic parking brake is ap-
plied or released.
– The warning light turns off when
the ignition switch is turned to the
“ON” position again.

The brake system warning light may

illuminate immediately after the engine
is started. However, it is not malfunc-
tioning if the warning light turns off

after the electronic parking brake is
released.
.

The brake system warning light may

illuminate after the electronic parking
brake is frequently applied and re-
leased. However, the electronic parking
brake system is not malfunctioning if
the light turns off for a short period of
time.
.

When the engine is started while the

electronic parking brake is applied/
released, the system may judge an
abnormal situation and the warning
light may illuminate. If the warning light
illuminates, turn the ignition switch
once to the “LOCK”/“OFF” position
and then restart the engine. Then,
apply/release the electronic parking
brake. If the warning light turns off,
the system will be restored.

Brake fluid level warning

This light illuminates when the brake fluid
level has dropped to near the “MIN” level of
the brake fluid reservoir with the ignition
switch in the “ON” position and with the
parking brake fully released.

If the brake system warning light should
illuminate while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN” mark in the
reservoir, do not drive the vehicle. Have
the vehicle towed to the nearest SUBARU
dealer for repair.

Electronic Brake Force Distribution
(EBD) system warning

The brake system warning light also
illuminates if a malfunction occurs in the
EBD system. In that event, it illuminates
together with the ABS warning light.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
while driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more

prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps.
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, apply the
parking brake and then restart it.
3. Release the parking brake. If both
warning lights turn off, the EBD system
may be malfunctioning. Drive carefully to
the nearest SUBARU dealer and have the
system inspected.
4. If both warning lights illuminate again
and remain illuminated after the engine
has been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle.
Instead, have the vehicle towed to the
nearest SUBARU dealer for repair.

Door open warning light

The warning light illuminates if any door or
the trunk lid is not fully closed. This
function is effective even if the ignition
switch is in the “LOCK”/“OFF” or “ACC”
position, or the key is removed from the
ignition switch.

Always make sure this light is not illumi-
nated before you start to drive.

All-Wheel Drive warn-
ing light (if equipped)

This light flashes if the vehicle is driven
with tires of differing diameters fitted on the
wheels or with an excessively low air
pressure in any of the tires.

WARNING

Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly park
in a safe location and then check
whether all four tires are the same
diameter and whether any of the
tires has a puncture or has lost air
pressure.

NOTE

If the temporary spare tire is used, the
AWD warning light may flash. Use of the
temporary spare tire should therefore
be restricted to the minimum time
necessary. Replace the temporary
spare tire with a conventional tire as
soon as possible.

Power steering warning
light (except STI)

While the engine is running, this warning
light illuminates when a malfunction has
been detected in the electric power steer-
ing system.

CAUTION

When the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.

NOTE

If the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent the
system components, such as the con-
trol computer and drive motor, from
overheating.
.

The steering wheel is operated fre-

quently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel
parking.
.

The steering wheel remains in the

fully turned position for a long period of
time.

At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power
assist limitation to occur too frequently,
that may result in a malfunction of the
power steering control system.

Vehicle Dynamics Con-
trol warning light/Vehicle
Dynamics Control op-
eration indicator light

Vehicle Dynamics Control warning
light

CAUTION

The Vehicle Dynamics Control sys-
tem provides its ABS control
through the electrical circuit of the
ABS. Accordingly, if the ABS is
inoperative, the Vehicle Dynamics
Control system becomes unable to
provide ABS control. As a result, the
Vehicle Dynamics Control system
also becomes inoperative, causing
the warning light to illuminate.
Though both the Vehicle Dynamics
Control and ABS are inoperative in
this case, the ordinary functions of
the brake system are still available.
You will be safe while driving with

this condition, but drive carefully
and have your vehicle checked at a
SUBARU dealer as soon as possi-
ble.

NOTE

If the electrical circuit of the Vehicle

Dynamics Control system itself mal-
functions, the warning light only illumi-
nates. At this time, the ABS (Anti-lock
Brake System) remains fully opera-
tional.
.

The warning light illuminates when

the electronic control system of the
ABS/Vehicle Dynamics Control system
malfunctions.
