I have a 2017 F150, all of a when I start the truck the dash display is showing the trailer display screen. It used to display the milage display. How do I get to go back to the milage display?

 

Use the arrow and "OK" buttons on the left side of the steering wheel to scroll through the menus.

 

Do you have something (like a hitch receiver with a light) or whatever plugged into the trailer connection at all times? Because if you do, it will default to thinking a trailer is plugged in and start on that screen
