COMFORT ADJUSTMENT In a severe frontal impact, the front airbag sensors detect deceleration and the system triggers the front airbag inflators. In a severe side impact, the side and curtain shield airbag sensor and/or the curtain shield airbag sensor trigger(s) the side and curtain shield airbag inflators and/or the curtain shield airbag inflator. 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 airbags operate, they produce 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, front seats, parts of the front and rear pillars and roof side) 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 front 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. 16L352a " 1 Side airbag module (airbag and inflator) 2 Airbag module for front passenger (airbag and inflator) 3 Side and curtain shield airbag sensor assembly 4 Airbag module for driver (airbag and inflator) 5 SRS warning light 6 Airbag sensor assembly 7 Curtain shield airbag module (airbag and inflator) 8 Curtain shield airbag sensor assembly 9 Front airbag sensors The SRS airbag system consists mainly of the above components, and their locations are shown in the illustration.
