Seat, seatbelt and SRS airbags The SRS side airbag is basically not designed to deploy if the vehicle is involved in a frontal collision or is struck from behind. Examples of such accidents are illustrated. J SRS airbag system monitors 1) First impact 2) Second impact In an accident where the vehicle is struck from the side more than once, the SRS side airbag deploys only once. Example: In the case of a double side impact collision, first with one vehicle and immediately followed by another from the same direction, once the SRS side airbag is activated on the first impact, it will not be activated on the second. A diagnostic system continually monitors the readiness of the SRS airbag system while the vehicle is being driven. The SRS airbag system warning light "AIRBAG" will show normal system operation by lighting for about 6 seconds when the ignition key is turned to the "ON" position. The following components are monitored by the indicator: D Front sub sensor (Right hand side) D Front sub sensor (Left hand side) D Airbag control module (including impact sensors) D Frontal airbag module (Driver's side) - CONTINUED - 1-63
