I have a 2008 aveo ls sedan took car in to see why the air bag light in instrument cluster was lit, they told me that the clock on the dash was bad causing the error. I never heard of this and they also said it would need reprogramming when replaced another what on my part. I do understand the it has a light to tell you that the passenger air bag is on. If it is something I can do myself I would rather do it then pay 270.00 for them to do it.
