As I remember, and it's been quite a while for me, it's one of the four or five icon that pop up on the first screen to present after a boot. I'm guessing it's labeled something like info.....not sure. You get this boot up when you go ignition on without the brake pedal depressed. Also not holding the button depressed for an extended amount of time as in when loading a tune. I looked in my files and have yet to locate my instructions, and I'm so very reluctant to go out in the very cold garage to do a walk through right now. Maybe later if no one else remembers better than me. BRRRR!!!
