" 1 Airbag module for front passenger
(airbag and inflator)
2 Airbag module for driver (airbag and inflator)
3 SRS warning light
4 Airbag sensor assembly
5 Front airbag sensor
The airbag sensor assembly consists of a safing sensor and
airbag sensors.
In a severe frontal impact, the airbag sensors detect
deceleration and the system triggers the front airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non−toxic gas to help restrain the forward or
lateral motion of the occupants.

When the SRS operates, it produces a fairly loud noise and
release some smoke and residue along with non−toxic gas.
This does not indicate a fire. This gas is normally harmless;
however, for those who have delicate skin, it may cause minor
skin irritation. Be sure to wash off any residue as soon as
possible to prevent any potential skin irritation.
Deployment of the airbags happens 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 swelling.
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.
