2016 SUBARU WRX sensor

Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
! Operation
A) Driver ’ s side
B) Passenger ’ s side
1) SRS AIRBAGs deploy as soon as a collision occurs.
2) After deployment, SRS AIRBAGs start to deflate immediately so that the driver ’ s vision is not
obstructed. The SRS airbags can function only when
the ignition switch is in the “ ON ” position.
The SUBARU advanced frontal airbag
system is designed to determine the
activation or deactivation condition of the
front passenger ’ s SRS frontal airbag
depending on the characteristic of item
(s) or person on the front passenger ’ s seat
monitored by the front passenger ’ s occu-
pant detection system 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 and the impact
sensors in the airbag control module
detect a predetermined 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 passenger ’ s modules)
instructing the module(s) to inflate the
SRS frontal airbag(s). On driver ’ s side, the
SRS knee airbag also inflates with the
SRS frontal airbag.1-46

A hands-free microphone or
other accessory in such a loca-
tion could be propelled through
the cabin with great force by the
curtain airbag, or it could prevent
correct deployment of the curtain
airbag. In either case, the result
could be serious injuries.
. Never hang or place coat hangers
or other hard or pointed objects
near the side windows. If such
items are present when the SRS
curtain airbags deploy, they
could be thrown through the
passenger compartment and
cause serious injuries. They
could also prevent proper opera-
tion of the SRS curtain airbags. WARNINGDo not put any kind of cover or
clothes or other objects over either
front seatback and do not attach
labels or stickers to the front seat
surface on or near the SRS side
airbag. They could prevent proper
deployment of the SRS side airbag,
reducing protection available to the
front seat ’ s occupant.
! Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ ON ” position.
The driver ’ s and front passenger ’ s SRS
side airbags and SRS curtain airbags
deploy independently of each other since
each has its own impact sensor. There-
fore, they may not both deploy in the same
accident. Also, the SRS side airbag and
SRS curtain 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
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
. Under the rear center seat
If the impact sensor that is located under
the rear center seat 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 under
the rear center seat 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, the 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 ’ s SRS frontal
airbag deploys or the driver ’ s and pas-
senger ’ s SRS frontal airbags deploy in aSeat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)

! Examples of the types of acci-
dents in which the SRS side
airbag and SRS curtain airbag
are not designed to deploy in
most cases
1) The vehicle is involved in frontal collision
with another vehicle (moving or station- ary).
2) The vehicle is struck from behind.
3) The vehicle pitches end over end.
In the event of accidents like those
illustrated, the SRS side airbag and SRS
curtain airbag are not designed to deploy
in most cases.
1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbag
In an accident where the vehicle is struck
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact.
Example: In the case of a double side
impact collision, first with one vehicle and
immediately followed by another from the same direction, once the SRS side airbag
and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second.
& SRS airbag system monitors
A diagnostic system continually monitors
the readiness of the SRS airbag system
(including front seatbelt pretensioners)
while the vehicle is being driven. The
SRS airbag system warning light will show
normal system operation by illuminating
for approximately 6 seconds when the
ignition switch is turned to the “ ON ”
position.
