2016 SUBARU LEGACY sensor

passenger’s occupant detection system
have failed, the SRS airbag system
warning light will illuminate. Have the
system inspected by your SUBARU deal-
er immediately if the SRS airbag system
warning light illuminates.
If your vehicle has sustained impact, this
may affect the proper function of the
SUBARU advanced frontal airbag system.
Have your vehicle inspected at your
SUBARU dealer. Do not let anyone use
the front passenger’s seat while you are
driving the vehicle to your SUBARU deal-
er.
!Passenger’s frontal airbag ON and
OFF indicators
Refer to“Front passenger’s frontal airbag
ON and OFF indicators”F3-14.
!Occupant detection system
The occupant detection system sensor is
installed under the seat and monitors the
total load on the front passenger’s seat.
The system has another sensor that
monitors the tension of the front passen-
ger’s seatbelt. Using the total seat load
and seatbelt tension data from the sen-
sors, the occupant detection system de-
termines whether the following airbags
should be deployed or not.

indicator
/: Front passenger’s frontal airbag OFF
indicator
If the front passenger’s frontal airbag ON
and OFF indicators do not work properly
even when the front passenger’s seat is
dry, do not allow anyone to sit on the front
passenger’s seat and have the occupant
detection system checked by your
SUBARU dealer.
!Conditions in which front passen-
ger’s SRS frontal airbag is not
activated
The front passenger’s SRS frontal airbag
will not be activated when any of the
following conditions are met regarding thefront passenger’s seat:
.The seat is empty.
.The seat is equipped with an appro-
priate child restraint system and an infant
is restrained in it. (See WARNING that
follows.)
.The front passenger’s occupant detec-
tion system is malfunctioning.
WARNING
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
PASSENGER’S SEAT EVEN IF THE
FRONT PASSENGER’S SRS FRON-
TAL AIRBAG IS DEACTIVATED. Be
sure to install it in the REAR seat in
a correct manner. Also, it is strongly
recommended that any forward fa-
cing child seat or booster seat be
installed in the REAR seat, and that
even children who have outgrown a
child restraint system be also
seated in the REAR seat. This is
because children sitting in the front
passenger’s seat may be killed or
severely injured should the front
passenger’s SRS frontal airbag de-
ploy. REAR seats are the safest
place for children.

!SUBARU advanced frontal airbag
operation
1) Driver’s side
2) Passenger’s side
The SUBARU advanced frontal airbag
system is designed to determine theactivation or deactivation condition of the
front passenger’s SRS frontal airbag
depending on the total load on the front
passenger’s seat monitored by the front
passenger’s occupant detection system
weight sensor. For this reason, only the
driver’s SRS frontal airbag may deploy in
the event of a collision, but this does not
mean failure of the system.
If the front sub sensors inside both front
fenders and the impact sensors in the
airbag control module detect a predeter-
mined amount of force during a frontal
collision, the control module sends signals
to the airbag module(s) (only driver’s
module or both driver’s and front passen-
ger’s modules) instructing the module(s)
to inflate the SRS frontal airbag(s). The
driver’s and front passenger’s SRS frontal
airbags use dual stage inflators. The two
inflators of each airbag are triggered either
sequentially or simultaneously, depending
on the severity of impact in the case of the
driver’s SRS frontal airbag and depending
on the severity of impact and the total load
on the seat in the case of the front
passenger’s SRS frontal airbag.
After deployment, the SRS airbag imme-
diately starts to deflate so that the driver’s
vision is not obstructed and the driver’s
ability to maintain control of the vehicle isnot impaired. The time required from
detecting impact to the deflation of the
SRS airbag after deployment is shorter
than the blink of an eye.
The driver’s and front passenger’s seat-
belt pretensioners operate at the same
time in both of the following cases.
.When only the driver’s SRS frontal
airbag deploys
.When driver’s and front passenger’s
SRS frontal airbags deploy
The driver’s SRS frontal airbag and front
passenger’s SRS frontal airbag are de-
signed to deploy in the event of an
accident involving a moderate to severe
frontal collision. They are not designed to
deploy in most lesser frontal impacts
because the necessary protection can be
achieved by the seatbelt alone. Also, they
are not designed to deploy in most side or
rear impacts or in most rollover accidents
because deployment of these airbags
would not help the occupant in those
situations. The driver’s and front passen-
ger’s SRS frontal airbags are designed to
function on a one-time-only basis.
SRS airbag deployment depends on the
level of force experienced in the passen-
ger compartment during a collision. That
level differs from one type of collision to
another, and it may have no bearing on

!SRS seat cushion airbag operation
1) Driver’s side
2) Passenger’s side
WARNING
The SRS seat cushion airbag is
designed not to deploy when the
seatbelt for the corresponding seat
is not fastened. For safety, all per-
sons in the vehicle should fasten
their seatbelts.
The SRS seat cushion airbags are de-
signed to deploy simultaneously when the
SRS frontal airbags deploy. For details
about the operating conditions, refer to
“SUBARU advanced frontal airbag opera-
tion”F1-57.
The front passenger’s SRS seat cushion
airbag is designed not to deploy in either
of the following conditions.
.The front passenger’s seatbelt is not
fastened (even when the front passen-
ger’s frontal airbag ON indicator illumi-
nates while the OFF indicator remains off).
.The front passenger’s frontal airbag
ON indicator is off while the OFF indicator
illuminates.
NOTE
When the front passenger’s SRS fron-
tal airbag is deactivated by the occu-
pant detection system, the front pas-
senger’s SRS seat cushion airbag is
also deactivated.
!SRS side airbag and SRS curtain
airbag operation
The driver’s and front passenger’s SRS
side airbags and SRS curtain airbags
deploy independently of each other be-
cause each has its own impact sensor.
Therefore, they may not both deploy in the
same accident. Also, the SRS side airbag
deploys independently of the driver’s and
front passenger’s SRS frontal airbags in
the steering wheel and instrument panel.
An impact sensor, which senses impact

Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
force, is located in each of the following
locations.
.In the left and right front doors
.In the left and right center pillars
.In the left and right rear wheel houses
.In the airbag control module
.In the left and right front fenders (only
SRS curtain airbags are designed to
deploy when the front sub sensors sense
a severe impact.)
A rollover sensor is also located inside the
airbag control module.
If the impact sensor that is located in the
airbag control module and one of the
center pillar impact sensors or front door
impact sensors together sense an impact
force above a predetermined level in a
side collision, the control module causes
both the SRS side airbag and curtain
airbag on the impacted side to inflate
regardless of whether the rear wheel
house impact sensor on the same side
senses an impact.
If the impact sensor that is located in the
airbag control module and one of the rear
wheel house impact sensors together
sense an impact force above a predeter-
mined level in a side collision, the control
module causes only the SRS curtain
airbag on the impacted side to inflate.Even if a frontal collision occurs, both right
and left SRS curtain airbags will deploy
when the front sensor and the control unit
determine that the impact results from an
offset frontal collision.
The SRS curtain airbags are designed to
deploy when the driver’sSRSfrontal
airbag deploys or the driver’s and pas-
senger’s SRS frontal airbags deploy in a
frontal collision, and also when the system
determines that the collision is an offset
frontal collision. The SRS curtain airbags
are basically designed not to deploy in a
frontal collision when the SRS frontal
airbags do not deploy or the system
determines that the collision is other than
an offset frontal collision.
If the rollover sensor detects rollover of the
vehicle, the control module inflates the
SRS curtain airbags. At this time, the
driver’s and front passenger’s seatbelt
pretensioners also operate at the same
time.
After the deployment, the SRS side airbag
immediately starts to deflate. The time
required from detection of an impact to
deflation of an SRS side airbag after
deployment is shorter than the blink of
an eye.
The SRS curtain airbag remains inflatedfor a while following deployment then
slowly deflates.
The SRS side airbag and SRS curtain
airbag deploy even when no one occupies
the seat on the side on which an impact is
applied.
The SRS side airbag and SRS curtain
airbag are designed to deploy in the event
of an accident involving a moderate to
severe side impact collision. They are not
designed to deploy in most lesser side
impact. Also, they are not designed to
deploy in most rear impacts because SRS
side airbag and SRS curtain airbag
deployment would not help the occupant
in those situations.
The SRS side airbag and SRS curtain
airbag deployment depend on the level of
force experienced in the passenger com-
partment during a side impact collision.
That level differs from one type of collision
to another, and it may have no bearing on
the visible damage done to the vehicle
itself.
The SRS curtain airbags are also de-
signed to deploy when the vehicle is in an
extremely inclined state such as during a
rollover. They are not designed to deploy
in most lesser inclined state.

If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system.
.Flashing or flickering of the warn-
ing light
.No illumination of the warning
light when the ignition switch is
first turned to the“ON”position
.Continuous illumination of the
warning light
.Illumination of the warning light
while driving
Immediatelytakeyourvehicleto
your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, theseatbelt pretensioners and/or SRS
airbags will operate improperly (e.g.
SRS airbags may inflate in a very
minor collision or not inflate in a
severe collision), which may in-
crease the risk of injury.
&SRS airbag system servicing
WARNING
.When discarding an airbag mod-
ule or scrapping the entire vehi-
cle damaged by a collision, con-
sult your SUBARU dealer.
.The SRS airbag has no user-
serviceable parts. Do not use
electrical test equipment on any
circuit related to the SRS airbag
system. For required servicing of
the SRS airbag, consult your
nearest SUBARU dealer. Tamper-
ing with or disconnecting the
system’s wiring could result in
accidental inflation of the SRS
airbag or could make the system
inoperative, which may result in
serious injury.
