If you can't figure it out, you can always disconnect the battery and re-connect it, that may reset the light.

Just remember that you will need the radio code handy so that you can use your radio once you reconnected the battery.

Believe it or not, I have saved myself many trips to the dealer for lights that just go on, sometimes without real reason.

If it continues to come on, then you should definately go and get it checked out.

Good Luck
