The SRS airbag sensor assemblies consist of a safing sensor and
driver and front passenger airbag sensors.
In a severe frontal impact, the airbag sensors detect deceleration and
the system triggers the front airbag inflators and seat belt
pretensioners. Then a chemical reaction in the inflators momentarily
fills the airbags with non−toxic gas to help restrain the forward or
lateral motion of the occupants. Then the inflators fill the airbags
and the seat belts are quickly drawn back in by the retractors to help
restrain forward motion of the occupants.
When the SRS operates, it produces a fairly loud noise and release
some smoke along with non−toxic gas. This does not indicate a fire.
Be sure to wash off any residue as soon as possible to prevent minor
skin irritation.
Deployment of the airbags happen in a fraction of a second, so the
airbags must inflate with considerable force. While the system is
designed to reduce serious injuries, it may also cause minor burns or
abrasions and swellings.
Parts of the airbag module (steering wheel hub, dashboard) may be
hot for several minutes, but the airbags themselves will not be hot.
The airbags are designed to inflate only once.
A crash severe enough to inflate the driver and front passenger
airbags may break the windshield as the vehicle buckles. In vehicles
with a front passenger airbag, the windshield may also be damaged
by absorbing some of the force of the inflating airbag.
