Seat, seatbelt and SRS airbags
C) After deployment, SRS side airbag starts to deflate im-
mediately.
The SRS side airbag can function only when the igni-
tion switch is in the “ON” position.
The driver’s and front passenger’s SRS side airbags
deploy independently of each other since each has its
own impact sensor. Also, the SRS side airbag deploys
independently of the frontal airbags in the steering
wheel and instrument panel.
An impact sensor is incorporated into each of the ve-
hicle’s center pillars. If either sensor detects a certain
predetermined amount of force during a side impact
collision, the control module sends a signal to the side
airbag module on the impacted side of the vehicle, in-
structing it to inflate the SRS side airbag. Then the
side airbag module produces gas, which instantly in-
flates the SRS side airbag. After the deployment, the
SRS side airbag immediately starts to deflate. The
time required from detecting impact to the deflation of
the SRS side airbag after deployment is shorter than
the blink of an eye.
The SRS side airbag deploys even when no one occu-
pies the seat on the side on which an impact is ap-
plied.
When the SRS side airbag deploys, a sudden, fairly
loud inflation noise will be heard and some smoke will
be released. These occurrences are normal result of
the deployment. This smoke does not indicate a fire in
the vehicle.
Do not touch the SRS side airbag system com-
ponents around the front seatback with bare
hands right after deployment. Doing so can
cause burns because the components can be
very hot as a result of deployment.
The SRS side airbag is designed to deploy in the event
of an accident involving a moderate to severe side im-
pact collision. It is basically not designed to deploy in
lesser side impact. Also, it is basically not designed to
deploy in frontal or rear impacts because SRS side air-
bag deployment would not help the occupant in those
situations.
Each SRS side airbag is designed to function on a
one-time-only basis.
SRS side airbag deployment depends on the level of
force experienced in the passenger compartment dur-
ing a side impact collision. That level differs from one
