The SRS light should come on as a self test when you first start the car, but it should go out in a reasonable amount of time 6 or 8 seconds, if it stays out once driving down the road all should be OK. If it comes on and stays on there is a fault in the system and codes need to be retrieved and diagnosis done. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
