Afs Off- Any Help As To What This Is?

[absenthminded]

I am getting a flashing AFS off on my dash of my 04 LS430. I don't have a manual, it is on back order, and the AFS acronym is the only one i haven't figured out. I can hit the button, but it makes no difference. It comes and goes. Some times on for a half hour and then goes off or other times it will stay on all day. Any help would be appreciated.
