2010 SUBARU LEGACY check engine

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)
The AT oil temperature warning light “AT
OIL TEMP ”illuminates when the ignition
switch is turned to the “ON ”position and
turns off after approximately 2 seconds. 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- Instruments and controls

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 when the engine is started im-
mediately after the electronic parking
brake is applied or released. However,
the electronic parking brake system is
not malfunctioning if the warning light
turns off after the electronic parking brake is applied or released after that. .
The brake system warning light may
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 fully 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 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
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.
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 7-34.
! Parking brake apply inhibit warning
The brake system warning light flashes for
10 seconds and a chirp sound will be
heard if the parking brake switch is
operated when the parking brake cannot be applied. !
Frequent operation warning
The brake system warning light flashes for
20 seconds and a chirp sound will be
heard if the parking brake switch is
operated too frequently. In this case, the
operation of the parking brake switch is
restricted to protect the electronic parking
brake system.
NOTE
Wait until the warning light turns off. ! Emergency released warning
The brake system warning light flashes
when the parking brake is automatically
released in case of an emergency. & Hill Holder indicator light
WARNING

switch is turned to the “ON ”position and
turns off several seconds after the engine
has started. This lighting pattern indicates
that the Vehicle Dynamics Control system
is operating normally. ! Vehicle Dynamics Control warning light
CAUTION
The Vehicle Dynamics Control sys-
tem provides its ABS control
through the electrical circuit of the

ABS system. 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 systems are inop-
erative 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 possible.
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 systemmalfunctions.
