The SRS airbag can function only when
the ignition switch is in the “ON” position.
The Subaru advanced frontal airbag sys-
tem is designed to determine the activa-
tion or deactivation condition of the front
passenger’s SRS frontal airbag depend-
ing on the total load on the front passen-
ger’s seat monitored by the front passen-
ger’s occupant detection system weight
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 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
