1-52 Seat, seatbelt and SRS airbags
! Operation
1) Driver’s side
2) Passenger’s side
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
passenger’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
airbag control module detect a predeter-
mined 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 passen-
ger ’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 passen-
ger ’s SRS frontal airbag. After deploy-
ment, the SRS airbag immediately starts
to deflate so that the driver’s vision is not
obstructed. The time required from detect-
ing impact to the deflation of the SRS
airbag after deployment is shorter than the
blink of an eye.
Both when only the driver’s SRS frontal
airbag deploys and the driver’s and front
passenger’s SRS frontal airbags deploy,
the driver’s and front passenger’s seatbelt
pretensioners operate at the same time.
Although it is highly unlikely that the SRS
airbag would activate in a non-accident
situation, should it occur, the SRS airbag
will deflate quickly, not obscuring vision
and will not interfere with the driver’s
ability to maintain control of the vehicle.
When the SRS airbag deploys, a sudden,
fairly loud inflation noise will be heard and
some smoke will be releas ed. Thes e
occurrences are a normal result of the
deployment. This smoke does not indicate
a fire in the vehicle.
