Warning and indicator lights Several of the warning and indicator lights
illuminate when the ignition switch is
initially turned to the “ ON ” position. This
permits checking the operation of the
bulbs.
Apply the parking brake and turn the
ignition switch to the “ ON ” position. For
the system check, the following lights
illuminate and then turn off after several
seconds or after the engine has started.
: Seatbelt warning light
(The seatbelt warning light turns off

Instruments and controls/Warning and indicator lights
& Front passenger ’ s frontal
airbag ON and OFF indica-
tors
ON / : Front passenger ’ s frontal airbag ON
indicator
/ : Front passenger ’ s frontal airbag OFF
indicator
The front passenger ’ s frontal airbag ON
and OFF indicators show you the status of
the front passenger ’ s SRS frontal airbag.
The indicators are located next to the
clock in the center portion of the dash-
board.
When the ignition switch is turned to the
“ ON ” position, both the ON and OFF
indicators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators turn
off for 2 seconds. After that, one of the indicators illuminates depending on the
status of the front passenger ’ s SRS frontal
airbag determined by the SUBARU ad-
vanced frontal airbag system monitoring.
If the front passenger ’ s SRS frontal airbag
is activated, the passenger ’ s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain off.
If the front passenger ’ s SRS frontal airbag
is deactivated, the passenger ’ sfrontal
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 indica-
tors remain illuminated or off simulta-
neously even after the system check
period, the system is malfunctioning.
Contact your SUBARU dealer immedi-
ately for an inspection. & CHECK ENGINE warn-
ing light/Malfunction in-
dicator light CAUTIONIf 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 a problem or potential
problem somewhere in the emission con-
trol system.
! If the light illuminates steadily
If the light illuminates steadily while driving
or does not turn off 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.3-16

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
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 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
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 11-13.
CAUTIONDo not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
& Engine low oil level
warning indicator (ex-
cept STI) This indicator appears when the engine oil
level decreases to the lower limit.
If the engine low oil level warning indicator
appears 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 -
13.
If the warning indicator does not disappear
after refilling the engine oil, or the warning
indicator appears even though the engine
oil level is within the normal range, have
the vehicle checked by a SUBARU dealer.Instruments and controls/Warning and indicator lights

Instruments and controls/Warning and indicator lights
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 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
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 “ Brake system
warning light ” F 3-21.
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 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,3-20

Instruments and controls/Warning and indicator lights
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, 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.
! Electronic parking brake system
warning (models with electronic
parking brake system)
The brake system warning light illumi-
nates when the electronic parking brake
system is malfunctioning. If the warning light illuminates, 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 pushed. For details, refer to
“ Electronic parking brake (models with
electronic parking brake system) ” F 7-44.
! Frequent operation warning
The brake system warning light illumi-
nates 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 sys-
tem.
! Vacuum pump system warning (ex-
cept STI)
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.3-22

& Door open warning
lightThe 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 place 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. & Power steering warn-
ing light (except STI) 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.
CAUTIONWhen 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 fre-
quently, that may result in a malfunc-
tion of the power steering control
system.
& LED headlight warning
light (if equipped) This light illuminates if the LED headlights
malfunction. Have your vehicle inspected
at a SUBARU dealer as soon as possible.Instruments and controls/Warning and indicator lights
