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
