OCCUPANT RESTRAINT SYSTEM " 1 Front passenger occupant classification system (ECU and sensors) 2 Side and curtain shield airbag sensor assemblies 3 Side airbag modules (airbag and inflator) 4 Curtain shield airbag modules (airbag and inflater) 5 Curtain shield airbag sensor assemblies 6 SRS warning light 7 Front passenger's seat belt buckle switch 8 "AIRBAG OFF" and "AIRBAG ON" indicator lights 9 Airbag sensor assembly The SRS side airbag and curtain shield airbag system consists mainly of the above components, and their locations are shown in the illustration. The SRS side airbag and curtain shield airbag system is controlled by the airbag sensor assembly. The airbag sensor assembly consists of a safing sensor and airbag sensor. In a severe side impact, the side and curtain shield airbag sensor and/or the curtain shield airbag sensor trigger(s) the side airbag inflators and/or the curtain shield airbag inflators. At this time a chemical reaction in the inflators quickly fills the airbags with non−toxic gas to help restrain the lateral motion of the occupants. When the airbags inflate, they produce a fairly loud noise and release some smoke and residue along with non−toxic gas. This does not indicate a fire. This smoke may remain inside the vehicle for some time, and may cause some minor irritation to the eyes, skin or breathing. Be sure to wash off any residue as soon as possible to prevent any potential skin irritation with soap and water. If you can safely exit from the vehicle, you should do so immediately. 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. Front seats as well as parts of the front and rear pillars, and roof side rail may be hot for several minutes, but the airbags themselves will not be hot. The airbags are designed to inflate only once. CAUTION SRS side airbags and curtain shield airbags inflate with considerable force. To reduce the possibility of death or serious injury when they inflate, the driver, front passenger and rear outboard passengers must: D Wear their seat belts properly. D Remain properly seated with their backs upright and against the seats at all times. 134
