SO a third time this happens to me! I started to read somethings on the web about this "light" because everyone I talked to (non mechanics) had no idea what it was (when i bought the car it had no manual). It's the Supplemental Restraint System. It lights up when you start the car and "runs a test" to make sure that the seatbelt, airbags, and some other things are in working order. It stays on for about 6 seconds and then goes off, that means everything is ok. When it comes back on you have a problem. So I am reading all these stories about people paying hundreds of dollar to get this light reset because if you are driving along at 60mph and that lights on your airbags could deploy and cause you to wreck, hurt yourself, others, or even die! I also read that the light coming on (in my case) could potentially be caused by low battery voltage. I still have no idea what is wrong with this hunk of metal! I had a new battery put in before all of this started happening. and when i towed the car to have that battery looked at they said it wasn't the battery and they didn't know what it was. took it somewhere else they said the alternator was bad, had that replaced, still didn't work! then we talked to someone and they said to check the fuses. we did and we thought that was it, some blown fuses, we replaced them and the car worked fine.. for a week then the same problem again.
