Instruments and controls/Warning and indicator lights
If the engine coolant temperature in-
creases over the specified range, the
indicator light/warning light blinks in
RED. At this time, the engine is close to
overheating.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
When the indicator light/warning light
blinks in REDor illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps to take in the
case of engine overheating. Refer to
“ Engine overheating ”F 9-12. After that,
have the system checked by your nearest
SUBARU dealer.
Also, if the indicator light/warning light
often blinks in RED, the electrical system
may be malfunctioning. Contact your
SUBARU dealer for an inspection.
NOTE
If the engine is restarted after a certain
driving condition, this indicator light/
warning light may illuminate in RED.
However, this is not a malfunction if the
indicator light/warning light turns off
after a short time.
&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
illuminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to
“Engine oil ”F 11-10.
CAUTION
Do not operate the engine with the
oil pressure warning light illumi-
nated. This may cause serious en-
gine damage.
&Engine low oil level
warning light
This light illuminates when the engine oil
level decreases to the lower limit.
If the engine low oil level warning light
illuminates 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 ”F 11-10.
If the warning light does not turn off after
refilling the engine oil, or the warning light
illuminates 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
light will turn off.

.The warning light may illuminate
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 light
This light illuminates 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.
&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
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 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
Instruments and controls/Warning and indicator lights
–CONTINUED –3-19

Instruments and controls/Warning and indicator lights
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 keepdriving straight ahead while gradu-
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 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 more than 25 mph (40
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 25 mph (40 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 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 25 mph
(40 km/h).
– The warning light illuminates
during 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 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
“Electronic
Brake Force Distribution (EBD) system
warning ”F 3-22.
NOTE
If the warning light behavior is as
described in the following conditions,
the ABS may be considered normal.
. The warning light illuminates when
the ignition switch is turned to the
“ ON ”position and turns off approxi-
mately 2 seconds after the engine has
started.
. 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 25 mph (40
km/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
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.
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.
The brake system warning light has the
following functions.
! 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

Instruments and controls/Warning and indicator lights
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
location 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 location.
2. Shut down the engine, apply the
parking brake and then restart it.
3. Release the parking brake. Even 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.
! Vacuum pump system warning
(turbo models)
This light illuminates when a malfunction
is detected in the vacuum pump system.NOTE
The vacuum pump system assists the
boost pressure when driving at high
altitudes while the engine is cold.
&Low fuel warning light
The low fuel warning light illuminates
when the tank is nearly empty, at approxi-
mately 2.6 US gal (10.0 liters, 2.2 Imp gal).
It only operates when the ignition switch is
in the “ON”position.
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light
illuminates. Engine misfires as a
result of an empty tank could cause
damage to the engine.
NOTE
This light does not turn off unless the
tank is replenished up to an internal
fuel quantity of approximately 4.5 US
gal (17 liters, 3.7 Imp gal).

!Hill start assist warning light
While the engine is running, if there are
any malfunctions in the Hill start assist
system, the warning light will illuminate.
WARNING
When the Hill start assist warning
light illuminates, have the vehicle
inspected at an authorized SUBARU
dealer.
! Hill start assist OFF indicator light
While the Hill start assist system is
deactivated, the Hill start assist OFF
indicator light illuminates continuously to
inform the driver that the Hill start assist
system is not operational.
&Door open warning
light
The warning light illuminates if any door or
the rear gate 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 (CVT models)
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
If the AWD warning light flashes,
promptly park in a safe location then
check whether all four tires are the
same diameter and whether any of
the tires has a puncture or has lost
air pressure for some other reason.
Continuing to drive with the AWD
warning light flashing can lead to
powertrain damage.
&Power steering warn-
ing light
This warning light illuminates when the
ignition switch is turned to the
“ON ”
position and turns off after the engine
has started. This indicates that the warn-
ing system is working properly. 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.

Instruments and controls/Warning and indicator lights
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 fre-
quently, that may result in a malfunc-
tion of the power steering control
system.
&Vehicle Dynamics
Control warning light/
Vehicle Dynamics Con-
trol operation 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.
Although both the Vehicle Dynamics
Control system and ABS 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 system
malfunctions.
The Vehicle Dynamics Control system is
probably inoperative under any of the
following conditions. Have your vehicle
checked at a SUBARU dealer immedi-
ately.
. The warning light does not illuminate when the ignition switch is turned to the
“ON
”position.
. The warning light illuminates while the
vehicle is running.
NOTE
If the warning light behavior is as
described in the following examples,
the Vehicle Dynamics Control system
may be considered normal.
. The warning light illuminates when
the ignition switch is turned to the
“ ON ”position and turns off approxi-
mately 2 seconds after the engine has
started.
. The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
. The warning light illuminates after
the engine has started and turns off
while the vehicle is subsequently being
driven.
. The warning light illuminates during
driving, but it turns off immediately and
remains off.
. The warning light illuminates when
the engine has stalled and continues to
illuminate after the engine has been
restarted. However, it will turn off once
the vehicle starts moving.
