MPG never changes!

I got my 23 platinum tundra in October and my MPG has been at 11.9 since the day I got it. It never fluctuates at all. Was wondering if anybody else has this issue or if your MPG is constantly changing and if there is some sort of software reset or something to fix??

 

You should be able to reset it via the giant screen if you go into settings and I believe there's like a trip history where you can clear the current MPG reading or store it as a data point and then it resets it (it'll show a bar graph of past entries).

You can also reset it by using the steering wheel controls. You just need to scroll to the fuel monitoring display then press and hold the okay or whatever its labeled button on the left hand side of the steering controls.

 

Holding the ok button fixed it right up!! Thanks for the help!!
