System operation
CAUTION
Do not touch the SRS airbag system
components with bare hands right
after deployment. Doing so can
cause burns because the compo-
nents can be very hot as a result of
deployment.
The SRS airbags can function only when
the ignition switch is in the
“
ON
”
position.
When the SRS airbag(s) deploy(s), a
sudden, fairly loud inflation noise will be
heard and some smoke will be released.
These occurrences are a normal result of
the deployment. This smoke does not
indicate a fire in the vehicle.

SUBARU advanced frontal airbag
operation
1) Driver

’
s side
The SUBARU advanced frontal airbag
system is designed to determine the
activation or deactivation condition of the
front passenger
’
s SRS frontal airbag
depending 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
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 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
passenger
’
s SRS frontal airbag.
After deployment, the SRS airbag imme-
diately starts to deflate so that the driver
’
s
vision is not obstructed and the driver

s
ability to maintain control of the vehicle is
