speed setting

I've just took delivery of my Prime this past Friday, couldn't be happier with the bike! I'm have some issues trying to set the speed limit on the display as it's a different menu set up from what I can find on YouTube or the manual. I don't have a speed limit option on the main menu or tire size setting? can anyone help with this issue? I would like to be able to adjust my speed and make sure I have the proper parameters set into my display. Thanks in advance for the help, happy riding!
