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
flash for 6 seconds, to warn that the
seatbelt(s) is/are unfastened. If the dri-ver ’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
seatbelt(s) will alternate between
steady illumination and flashing at
15-second intervals. The chime will
not sound. – At speeds higher than approxi-
mately 9 mph (15 km/h)
The warning light(s) for unfastened
seatbelt(s) will alternate between
flashing and steady illumination at
15-second intervals and the chime
will sound while the warning light(s)
is/are 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.
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“ Manual seat ”F1-3 (models equipped
with manual seats only).

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. . 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. (Models
equipped with manual seats only)
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.

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 a problem or potential
problem somewhere in the emission con-
trol system. ! If the light illuminates constantly
If the light illuminates constantly while
driving or does not turn off after the engine
starts, an emission control system mal-
function has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately.
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 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/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 conform
to the following instructions. . 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

&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
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
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
illuminated, contact your nearest
SUBARU dealer immediately.
& Engine low oil level
warning light
This light illuminates when the engine oil
level decreases to the lower limit. The
illuminating conditions and remaining oil
level are shown in the following items.
2.5 L models:.when the ignition switch is in the “ON ”
position but the engine is not running:
approximately 1.9 US qt (1.8 liters, 1.6
Imp qt) . while the engine is running: approxi-
mately 3.2 US qt (3.0 liters, 2.6 Imp qt)
3.6 L models: . when the ignition switch is in the “ON ”
position but the engine is not running:
approximately 4.0 US qt (3.8 liters, 3.3
Imp qt) . while the engine is running: approxi-
mately 5.6 US qt (5.3 liters, 4.7 Imp qt)
If the engine low oil level warning light
illuminates while driving, park the vehicle
at 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 if necessary. Refer to
“Engine oil ”F 11-12.
If the warning light does not turn off after
refilling with engine oil or the warning light
illuminates even though the engine oil
level is within the normal range, have the
system checked by a SUBARU dealer.
NOTE . The engine low oil level warning
light will not turn off immediately even
if you replace or add engine oil. It will
turn off only when the vehicle is idling
and the engine is warmed up comple-
tely.. When the vehicle is considerably
inclined on an uphill or steep slope, the
warning light may illuminate tempora-
rily due to the movement of engine oil
in the engine. & AT OIL TEMP warning
light (AT and CVT mod-els)
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.
& 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 go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for thosetires.)
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 malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of re-
placement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. 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 stea-
dily after blinking for approximately one
minute, 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 and keep
driving straight ahead while gradu- Instruments and controls

ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
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, replace it with a spare tire
as soon as possible.
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 minute,
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 more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion 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
when the vehicle speed ex-
ceeds approximately 12 km/h
(8 mph).
– The warning light illuminates
during driving.
– The warning light flashes.
. When the warning light is on (and
brake system warning light is
off), the ABS function shuts
down; however, the conventional
brake system continues to oper-
ate normally.
. When the warning light is flash-
ing, the ABS system may be
malfunctioning. However, the
conventional brake system con-
tinues to operate normally.
The ABS warning light illuminates to-
gether with the brake system warning light
if the EBD system malfunctions. For
further details of the EBD system mal-

function warning, refer to“Brake system
warning light ”F 3-17.
NOTE
If the warning light behavior is as
described in the following conditions,
the ABS system may be considered normal. . The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.. The warning light remains illumi-
nated after the engine has been started,
but it turns off when the vehicle speed
reaches approximately 8 mph (12km/h).. The warning light illuminates during
driving, but it turns off immediately and
remains 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 prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.
. If the brake system warning light
flashes, the electronic parking
brake system may be malfunc-
tioning. Immediately stop your
vehicle in a safe location, use
tire stops under the tires to
prevent the vehicle from moving
and contact your SUBARU deal-
er. For details, refer to “Electro-
nic parking brake ”F 7-31. NOTE .
When the ignition switch is turned to
the “LOCK ”position with the electronic
parking brake applied, the brake sys-
tem warning light remains illuminated
for approximately 30 seconds and then
turns off.. When the electronic parking brake
switch is pressed to apply the electro-
nic parking brake while the ignition
switch is in the “LOCK ”position, the
brake system warning light illuminates,
remains illuminated for approximately
30 seconds and then turns off.. Even if the brake system warning
light flashes, if the warning light beha-
vior is as described in the following
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
flash immediately after the engine is
started. However, it is not malfunction-
ing if the warning light turns off after
the electronic parking brake is re-leased. . The brake system warning light may Instruments and controls

flash after the electronic parking brake
is frequently applied and released.
However, the electronic parking brake
system is not malfunctioning if the light
turns off for a short period of time.
This light has the following functions: ! Parking brake warning
The light illuminates with the parking
brake applied while the ignition switch is
in the “ON ”position. It turns off when the
parking brake is released. ! 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 released.
If the brake system warning light should
illuminate while driving (with the parking
brake released and with the ignition switch
positioned in “ON ”), it could be an indica-
tion 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
during 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 vehi-cle ’s motion may therefore become some-
what 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, 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. Refer to
“Brake fluid ”
F 11-25.
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. ! Electronic parking brake system warning
The brake system warning light flashes
when the electronic parking brake system
is malfunctioning. If the warning light
flashes, promptly park in a safe location
as soon as possible and contact your
SUBARU dealer.
The brake system warning light remains
illuminated when the parking brake cannot
be released even if the parking brake
switch is pulled. For details, refer to“ Electronic parking brake ”F 7-31.
! Parking brake apply inhibit warning
