I believe there is a date you set for when your kit expires. It's under one of the options in the settings screen. I'm guessing your current date shows it expired. Check the date printed on your kit and input that into the settings.I keep getting 'Service tire mobility kit' Message on my screen. Any idea how to turn off the message? I press OK every time so the message disappears but then reappears as i start my mach E next time!
