Airbag module for driver (airbag and inflator) The airbag sensor assembly consists of a safing sensor and airbag sensor. The front airbag sensors constantly monitor the forward deceleration of the vehicle. If an impact results in a forward deceleration beyond the designed threshold level, the system triggers the airbag inflators. At this time a chemical reaction in the inflators very quickly fills the airbags with non−toxic gas to help restrain the forward motion of the occupants. The front airbags then quickly deflate, so that there is no obstruction of the driver's vision should it be necessary to continue driving. When the airbags inflate, they produce a 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. Landing hard or vehicle falling The SRS front airbags may also deploy if a serious impact occurs to the underside of your vehicle. Some examples are shown in the illustration. The SRS front airbag system consists mainly of the following components, and their locations are shown in the illustration. 1. Front airbag sensors 2. SRS warning light 3. Airbag module for front passenger (airbag and inflator) 4. "AIRBAG ON" and "AIRBAG OFF" indicator lights 5. Front passenger occupant classification system (ECU and sensors) 6.
