Seat, seatbelt and SRS airbags

T Operation

A) SRS side airbag deploys as soon as a collision oc-

curs.

B) 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 of which an impact is applied.

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
