2016 SUBARU LEGACY check engine light

Instruments and controls/Warning and indicator lights
&Door open indicator
When any of the doors, the rear gate
(Outback) or the trunk lid (Legacy) is not
fully closed, the door open indicator
appears. This function is effective even if
the ignition switch is in the“LOCK”/“OFF”
or“ACC”position (all models) or the key is
removed from the ignition switch (models
without“keyless access with push-button
start system”).
The open door is indicated by the corre-
sponding part of the door open indicator.
Always make sure this indicator does not
appear before you start to drive.
&Windshield washer
fluid warning indicator
This indicator appears 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).
&All-Wheel Drive warn-
ing light (CVT models)
WARNING
Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly parkin 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.
NOTE
If the temporary spare tire is used, the
AWD warning light may flash. Use of
the temporary spare tire should there-
fore be restricted to the minimum time
necessary. Replace the temporary
spare tire with a conventional tire as
soon as possible.
This light flashes if the vehicle is driven
with tires of different diameters fitted on its
wheels or with the air pressure exces-
sively low in any of its tires.
&Power steering warn-
ing light
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 steeringwheel 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.
&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
becomes inoperative, causing the
warning light to illuminate. Although
both the Vehicle Dynamics Control
and ABS are inoperative in this
case, the ordinary functions of the
brake system are still available. You
will be safe while driving in thiscondition, but drive carefully and
have your vehicle checked at a
SUBARU dealer as soon as possi-
ble.
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 systemmay be considered normal.
.The warning light illuminates right
after the engine is started but turns off
immediately and remains 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 turns off immediately and
remains off.
!Vehicle Dynamics Control opera-
tion indicator light
The indicator light flashes during activa-
tion of the skid suppression function and
during activation of the traction control
function.
NOTE
.The light may remain illuminated for
a short period of time after the engine
has been started, especially in cold
weather. This does not indicate the
existence of a problem. The light
should turn off as soon as the engine
has warmed up.
.The indicator light illuminates when
the engine has developed a problem
and the CHECK ENGINE warning light/
malfunction indicator light is on.
The Vehicle Dynamics Control system is

position.
.The light does not turn off even after a
period of approximately 2 seconds after
the ignition switch has been turned to the
“ON”position.
&Warning chimes and warning
indicator of the keyless ac-
cess with push-button start
system (if equipped)
Access key warning indicator
The keyless access with push-button start
system sounds a warning chime and the
access key warning indicator appears on
the combination meter in order to minimize
improper operations and help protect your
vehicle from theft.
When the warning chime sounds and/or
the warning indicator appears, take the
appropriate action.
You cannot turn the warning chimes off.
However, the volume setting of the outside
warning chime can be changed by aSUBARU dealer. Consult your SUBARU
dealer for details.
WARNING
Never drive the vehicle if the indi-
cator on the push-button ignition
switch is flashing in green when
starting the engine. This indicates
the status that the steering wheel is
not released and could result in an
accident involving serious injury or
death.
CAUTION
.When starting the engine again
after the operation indicator on
the push-button ignition switch
flashes in green, if the operation
indicator is still flashing in green,
there could be a steering lock
malfunction. Contact your
SUBARU dealer as soon as pos-
sible.

Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause damage to the
engine and/or fuel system.
&Fuel requirements
The engine is designed to operate using
unleaded gasolinewith an octane rating
of87 AKI (90 RON) or higher.
!Fuel octane rating
Using a gasoline with a lower octane
rating can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle
sometimes knocks lightly when you drive
up a hill or when you accelerate. See your
dealer or a qualified service technician if
you use a fuel with the specified octane
rating and your vehicle knocks heavily or
persistently.
!RON
This octane rating is the Research Octane
Number.!AKI
This octane rating is the average of the
Research Octane and Motor Octane
numbers and is commonly referred to as
the Anti Knock Index (AKI).
!Unleaded gasoline
The neck of the fuel filler pipe is designed
to accept only an unleaded gasoline filler
nozzle. Under no circumstances should
leaded gasoline be used because it will
damage the emission control system and
may impair driveability and fuel economy.
!California fuel
If your vehicle was certified to California
Emission Standards as indicated on the
underhood tune-up label, it is designed to
optimize engine and emission control
system performance with gasoline that
meets the clean burning low-sulfur Cali-
fornia gasoline specifications. If you live in
any other state than California, your
vehicle will operate on gasoline meeting
Federal specifications. Gasoline sold out-
side California is permitted to have higher
sulfur levels, which may affect the perfor-
mance of your vehicle’s catalytic converter
and may produce a sulfur exhaust odor or
smell. SUBARU recommends that you try
a different brand of unleaded gasoline
having lower sulfur to determine if the
problem is fuel related before returningyour vehicle to an authorized dealer for
service. The CHECK ENGINE warning
light/malfunction indicator light may also
turn on. If this occurs, return to your
authorized SUBARU dealer for diagnosis.
If it is determined that the condition is
caused by the type of fuel used, repairs
may not be covered by your warranty.
!MMT
Some gasoline contains an octane-en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/mal-
function indicator light may turn on. If this
happens, return to your authorized
SUBARU Dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not
be covered by your warranty.
!Gasoline for cleaner air
CAUTION
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty.
Your use of gasoline with detergent

ping mechanism may not func-
tion, causing fuel to overflow the
tank and creating a fire hazard.
.Stop refueling when the auto-
matic stop mechanism on the
fuel nozzle activates. If you con-
tinue to add fuel, temperature
changes or other conditions
may cause fuel to overflow from
the tank and create a fire hazard.
6. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
7. Put the cap back on, turn it clockwise
until you hear a clicking noise. Be certain
not to catch the tether under the cap while
tightening.
CAUTION
Make sure that the cap is tightened
until it clicks to prevent fuel spillage
in the event of an accident.
8. Close the fuel filler lid completely.
CAUTION
If you spill any fuel on the painted
surface, rinse it off immediately.
Otherwise, the painted surfacecould be damaged.
NOTE
.You will see the“”sign in the fuel
gauge. This indicates that the fuel filler
door (lid) is located on the right side of
the vehicle.
.If the fuel filler cap is not tightened
until it clicks or if the tether is caught
under the cap, the CHECK ENGINE
warning light/malfunction indicator
light may illuminate. Refer to“CHECK
ENGINE warning light/Malfunction in-
dicator light”F3-15.
CAUTION
.Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
.After refueling, turn the cap to the
right until it clicks to ensure that
it is fully tightened. If the cap is
not securely tightened, fuel may
leak out while the vehicle is being
driven or fuel spillage could
occur in the event of an accident,
creating a fire hazard.
.Do not let fuel spill on the exterior
surfaces of the vehicle. Because
fuel may damage the paint, be
sure to wipe off any spilled fuel
quickly. Paint damage caused by
spilled fuel is not covered under
the SUBARU Limited Warranty.
.Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit, and
your fuel tank and emission con-
trol system may be damaged. It
could also lead to fuel spillage
and a fire.
.Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
