2016 SUBARU IMPREZA 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 following sensors 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 front sub sensors
. the impact sensors in the airbag control
module
On the driver ’s side, the SRS knee airbag
also inflates with the SRS frontal airbag.

the cabin is stored in the roof side
(between the front pillar and a point over
the rear seat). An“SRS AIRBAG”mark is
located at the top of each center pillar.
In a moderate to severe side impact
collision, the SRS curtain airbag on the
impacted side of the vehicle deploys
between the occupant and the side
window and supplements the seatbelt by
reducing the impact on the occupant ’s
head.
For Crosstrek models, in a rollover, SRS
curtain airbags on both sides of the
vehicle deploy between the occupant
and the side window and supplement the
seatbelt by reducing the impact to the
occupant ’s head.
In an offset frontal collision, SRS curtain
airbags on both sides of the vehicle
deploy between the occupant and the
side window and supplement the seatbelt
by reducing the impact to the occupant ’s
head and chest.
! Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ON”position.
The following airbags deploy indepen-
dently of each other since each has its
own impact sensor. .
Driver ’s SRS side airbag
. Front passenger ’s SRS side airbag
. SRS curtain airbag (right-hand side)
. SRS curtain airbag (left-hand side)
Therefore, they may not both deploy in the
same accident. Also, the SRS side airbag
and SRS curtain airbag deploys indepen-
dently of the driver ’s and front passen-
ger ’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
For Crosstrek models, a rollover sensor is
also located inside the airbag control
module.
If both of the following sensors together
sense an impact force above a predeter-
mined 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.
. the impact sensor that is located under the rear center seat
.
one of the center pillar impact sensors
or front door impact sensors
If both of the following 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.
. the impact sensor that is located under
the rear center seat
. one of the rear wheel house impact
sensors
For Crosstrek models, if the rollover
sensor detects rollover of the vehicle, the
control module inflates the SRS curtain
airbags on both sides. 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 inflated
for a while following deployment then
slowly deflates.
