Mazda mx6 has problem with air bag warning light. Light was blinking on and off. It stopped blinking but it does not come on when the car is started or when the key is in the 3rd position. Now I am getting a warning beep of 5 beeps for 5 times when the car is started. It's very annoying. I can't find anything in the manuals or diagrams that have. Is there an easy reset/fix for this or do I really need to take it to the dealer? Please say there is hope.
