Seat, seatbelt and SRS airbags
! 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 total load on the front
passenger's seat monitored by the front
passenger's occupant 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.
