The SRS components are in operational readiness if the 1 indicator lamp is not lit when the engine is running. A malfunction in the system has been detected if the 1 indicator lamp: fails to go out after approximately 4 seconds after the engine was started does not come on at all comes on after the engine was started or while driving i For information on infants and children traveling with you in the vehicle and restraint systems for infants and children, see "Children in the vehicle" ( page 83). 66
