2016 SUBARU LEGACY check engine light

as a result of an empty tank
could cause damage to the en-
gine. Continuing to operate your
vehicle at an extremely low fuel
level may result in a reduction of
engine performance.State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.
CAUTION
.At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
.Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program or
its contractors or licensees.
California and a number of federal stateshave Inspection/Maintenance programs to
inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspec-
tion of the OBDII system.
.The inspection of the OBDII system
consists of a visual operational check of
the“CHECK ENGINE”warning light/mal-
function indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
.A vehicle
passes the OBDII system
inspection if proper operation of the
“CHECK ENGINE”warning light is ob-
served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
Starting and operating/State emission testing (U.S. only)
–CONTINUED–7-7

Starting and operating/Preparing to drive
.A vehiclefails the OBDII inspection if
the“CHECK ENGINE”warning light is not
properly operating (light is illuminated or is
not working due to a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle’s computer.
.A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors“NOT
READY”is greater than one. If the
vehicle’s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a few
days to reset the readiness monitors and
return for an emission re-inspection.
.Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being put
on a dynamometer, tell your emission
inspector
not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer.Otherwise, serious transmis-
sion damage will result.The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
program have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer. There are some states that
use four-wheel dynamometers in their
testing program. When properly used, this
equipment should not damage a SUBARU
AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
Preparing to drive
You should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition
of the tires. Also check tires for proper
inflation.
3. Look under the vehicle for any sign of
leaks.
4. Check that the hood, trunk (Legacy)
and rear gate (Outback) are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside
and outside mirrors.
7. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
8. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the“ON”position.
9. Check the gauges, indicator and warn-
ing lights after starting the engine.
10. Check that no small animals enter the
engine compartment.

NOTE
.Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
.For a short time after the engine has
started, the engine speed is kept high.
When the warm-up is completed, the
engine speed lowers automatically.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel and the usage condition (repeated
driving of a distance in which the
engine has not warmed up sufficiently).
In such a case, it is recommended that
you change to a different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly
such as a rapid start-up and a rapid
acceleration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.After the engine starts, the engine
speed will be kept high until the engine
has warmed up sufficiently.!MT models

&Stopping the engine
WARNING
Do not stop the engine when the
vehicle is moving. This will cause
loss of power to the power steering
and the brake booster, making steer-
ing and braking more difficult. It
could also result in accidental acti-
vation of the“LOCK”position on theignition switch, causing the steering
wheel to lock.
The ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
&Steering lock (models with-
out“keyless access with
push-button start system”)
After stopping the engine and the key is
removed from ignition switch, the steering
wheel will be locked due to the steering
lock function.
When the engine is restarted, the steering
lock will be automatically canceled.

point will prevent starting or cause the
engine to stop.
The remote engine start system is acti-
vated by pressing the fob button on your
remote engine starter transceiver (fob)
twice within 3 seconds. If the fob is withinoperating range of the system and the
start request is received, the following will
occur.
.The fob flashes and beeps once.
.The horn sounds once.
.The side marker lights, tail lights, and
parking lights flash once.
If the fob is not within range (the user is
too far away from the vehicle), the fob will
indicate two long flashes without beeping.
The system will check certain safety
preconditions before starting, and if all
conditions are met, the engine will start
within 5 seconds. After the engine starts,
the following will occur.
.The fob flashes and beeps twice.
.The horn sounds once.
.The side marker lights, tail lights, and

.You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.
.You might hear the sound of ABS
operating from the engine compart-
ment.
&Disc brake pad wear warning
indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle inspected by
the nearest SUBARU dealer.
ABS (Anti-lock Brake Sys-
tem)
WARNING
Always use the utmost care in
driving–overconfidence because
youaredrivingwithanABS
equipped vehicle could easily lead
to a serious accident.
CAUTION
.The ABS does not always de-
crease stopping distance. You
should always maintain a safe
following distance from other
vehicles.
.When driving on badly surfaced
roads, gravel roads, icy road, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS than
one without. When driving under
these conditions, therefore, re-
duce your speed and leave ample
distance from other vehicles.
.When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do notpump the brake pedal since
doing so may defeat the opera-
tion of the ABS.
The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when
the ABS operates.
The ABS will not operate when the vehicle
speed is below approximately 6 mph (10
km/h).
&ABS self-check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.
&ABS warning light
Refer to“ABS warning light”F3-18.
Starting and operating/ABS (Anti–lock Brake System)7-33

Starting and operating/Electronic Brake Force Distribution (EBD) system
Electronic Brake Force Dis-
tribution (EBD) system
The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
function fails, the EBD system also stops
working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
&Steps to take if EBD system
malfunctions
If a malfunction occurs in the EBD system,
the system stops working and the brake
system warning light and ABS warning
light illuminate simultaneously.
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. Apply the parking brake and turn off
the engine.
3. Restart the engine.
4. 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.
If both warning lights illuminate again
and remain illuminated after restarting
the engine:
1. Turn off the engine again.
2. Apply the parking brake.
3. Check the brake fluid level. For details
about checking the brake fluid level, refer
to“Checking the fluid level”F11-19.
.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
