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
