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 lamp
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 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.

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 lamp illuminat-
ing 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 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 thefollowing. . 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.

approximately 2 seconds when the igni-
tion switch is turned to the “ON ”position.
After that, this indicator light/warning light
changes to BLUEand maintains illumina-
tion in BLUE. This BLUE illuminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature in-
creases over the specified range, the
indicator light/warning light blinks inRED . 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 9-13. 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.
& AT OIL TEMP warning
light (AT models)
If this light illuminates when the engine is
running, it may indicate that the automatic
transmission 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. !Automatic transmission control
system warning
If the “AT OIL TEMP ”warning light flashes
after the engine starts, it may indicate that
the automatic transmission control system

is not working properly. Contact your
nearest SUBARU dealer for service im-
mediately. &Rear differential oil
temperature warning
light (STI)
CAUTION
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
illuminates. Continued driving with
this light illuminated can 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 at the
nearest safe place. 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
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.

&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 8 mph
(12 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.
With a vehicle equipped with an EBD
system, the ABS warning light illuminates together 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) systemwarning ”F 3-22.
NOTE
If the warning light behavior is as
described in the following conditions,
the ABS system may be considerednormal. . 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.
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. Instruments and controls
3-21
– CONTINUED –

3-22Instruments and controls
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.
& Low fuel warning light
The low fuel warning light illuminates
when the tank is nearly empty approxi-
mately 2.6 US gal (10.0 liters, or 2.2 Imp
gal). It only operates when the ignition
switch is in the “ON ”position. When this light illuminates, fill the fuel tank immedi-
ately.
NOTE
This light does not turn off unless the
tank is replenished up to an internal
fuel quantity of approximately 3.7 US
gal (14 liters, 3.1 Imp gal).
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.

!Vehicle Dynamics Control warning
light (yellow)
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
