Seat, seatbelt and SRS airbags
– CONTINUED –
! Operation
A) Driver’s side
B) Passenger’s side
The SRS airbag can function only when the ignition
switch is in the “ON” position.
The Subaru advanced frontal airbag system is de-
signed to determine activation or deactivation condi-
tion of the front passenger’s SRS frontal airbag de-
pending 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 driv-
er’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 predetermined amount of force during a frontal colli-
sion, 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). 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, backward-forward adjustment
of the driver’s seat position and fastening/unfastening
of the seatbelt 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 pas-
senger’s SRS frontal airbag. After the deployment, the
SRS airbag immediately start to deflate so that the
driver’s vision is not obstructed. The time required
