The airbag alarm ( on red letters )appears on the dashboard after driving the car for about 20 minutes and it does not go away until you turn off the car and starts all over again..
Its there a way to reset this alarm to make it go away for good?

 

That light is trying to tell you that something is wrong with the airbag system. To diagnose the problem, you need to hook the car up to a proper scanner (DRB III tool) to find the active and stored codes. Then you can fix the problem and erase the codes. In the meantime, your airbag system may not function when you need it.
Drive carefully and buckle up on your way over to the dealer to have this looked at properly. Bring lots of $.
