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 at least one problem or
potential problem somewhere in the emis-
sion control 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.NOTEThis 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 warn-
ing light turn off immediately. It may take
several driving trips. If the light does not
turn off, take your vehicle to your author-ized 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.

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 lightThis 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”F11 -
8.
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

NOTE.The warning light may stay illumi-
nated when the engine is started
straight after topping up or changing
the engine oil. In such cases, park the
vehicle on a level surface and wait for
more than a minute until the oil level
settles, after which 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 lightThis light illuminates when the fluid level in
the windshield washer fluid tank de-
creases to the lower limit (approximately
0.6 US qt, 0.6 liter, 0.5 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.

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 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 pres-
sure threshold, the low tire pressure
warning light should turn off a few
minutes later. Therefore, be sure to
install the specified size for the frontand 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
after the vehicle is started.
–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, Vehicle Dynamics
Control warning light, and brake systemwarning light illuminate simultaneously if
the EBD system malfunctions. For further
details of the EBD system malfunction
warning, refer to“Electronic Brake Force
Distribution (EBD) system warning”F3-
21.
NOTEIf 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 approximately 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 while driving.
.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 (red)This 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 properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.
The brake system warning light has the
following functions.
!Brake fluid level warningThis 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
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 EBD system may be malfunctioning if
the brake system warning light
/
,
Vehicle Dynamics Control 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 vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light
/
,
Vehicle Dynamics Control warning light
and ABS warning light
/
illuminate
simultaneously, take the following steps.
1. Stop the vehicle in the nearest safe, flatlocation.
2. Shut down the engine, apply the
parking brake and then restart it.
3. Fully release the parking brake.
4. Even if all the warning lights do not
come back on, the EBD system may have
a possible malfunction. Drive carefully to
the nearest SUBARU dealer and have the
system inspected.
5. If all the warning lights stay illuminated
or come back on after approximately 2
seconds, shut down the engine, apply the
parking brake and check the brake fluid
level.
.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.
.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 pressure system warning
The brake system warning light
/
will
illuminate when the vacuum pressure
sensor is malfunctioning or brake booster
pressure is decreasing.

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 lightThe 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.
For some models, only the open doors are
indicated by the warning lights.
Always make sure this light is not illumi-
nated before you start to drive.
&All-Wheel Drive warn-
ing light (CVT models)This light blinks 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.NOTEIf the temporary spare tire is used, the
AWD warning light may flash. Use of the
temporary spare tire should therefore
be restricted to the minimum time
necessary. Replace the temporary
spare tire with a conventional tire as
soon as possible.

&Power steering warning
lightWhile 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.NOTEIf 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 frequently,
that may result in a malfunction of the
power steering control system.
&Vehicle Dynamics Con-
trol warning light/Vehicle
Dynamics Control op-
eration 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 DynamicsControl 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
BrakeSystem)remainsfullyopera-
tional.
.The warning light illuminates when
the electronic control system of the
ABS/Vehicle Dynamics Control system
malfunctions.
.The Vehicle Dynamics Control warn-
ing light, ABS warning light, and brake
