The SRS airbag can function only when

the ignition switch is in the “ON” position.

The Saab advanced frontal airbag system

is designed to determine the activation or

deactivation condition of the front passen-

ger’s SRS frontal airbag depending on the

total load on the front passenger’s seat

monitored by the front passenger’s occu-

pant detection system weight sensor. For

this reason, only the driver’s SRS frontal

airbag may deploy in the event of a colli-

sion, but this does not mean failure of the

system.

If the front sub sensors inside both front

fenders and the impact sensors in the air-

bag control module detect a predeter-

mined amount of force during a frontal col-

lision, 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 in-

flate the SRS frontal airbag(s). The driv-

er’s and front passenger’s SRS frontal air-

bags use dual stage inflators. The two in-

flators of each airbag are triggered either

sequentially or simultaneously, depending

on the severity of impact, backward-for-

ward adjustment of the driver’s seat posi-

tion and fastening/unfastening of the seat-

belt 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
