COMFORT ADJUSTMENT 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. In a severe side impact, the side airbag sensor triggers the side airbag inflator. At this time a chemical reaction in the inflators very quickly fills the airbags with non-toxic gas to help restrain the forward or lateral motion of the occupants. The airbags then quickly deflate, so that here 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 physically and safely exit the vehicle after a collision, you should do so at the first opportunity. 16st04 " 1 Side airbag module (airbag and inflator) 2 Airbag module for front passenger (airbag and inflator) 3 Side airbag sensors 4 Airbag module for driver (airbag and inflator) 5 SRS warning light 6 Airbag sensor assembly 7 Front airbag sensors 8 Door side airbag sensors 9 Occupant detection sensor 10 Seat belt buckle switch The SRS airbag system mainly consists of the above components, and their locations are shown in the illustration.
