I hope someone is in the know here on this. I've done no electrical or dash work when all of the sudden today, the Air Bag light to the left of the gas gauge began blinking red. I tried the resetting trick (off, on, off when blinking begins...5 mississippi's etc. ) three separate times. It did reset each time and remain off for a few miles before it began blinking red again. I'm wondering if it could something more serious than just needing a reset. I drive it over 400 miles a day for work and need the security of a working air bag. Please advise...BTW, it's an 09 1.6 hatch with 240k on it. Thanks

You may need to see your dealer on this. Take a look at the SRS link.
