Is that the O/Speed warning? You can actually change how high or low you want it to be, but to disable it when you turn the car on the computer asks you to hit the up or down arrow to enter the computer display setup. I think you can scroll to O/Speed and then hit set or whatever to change it to on or off. I'd give you a more decriptive answer, but its like 10 degrees and snowing outside so i dont feel like going out side to see :-). Somone else in warmer climate can probally tell you better.
