button on the end of the left steering wheel stalk to cycle thru the data, as I remember.

 

That toggles from MPG to Miles driven to Date, etc...but only within the selected default trip. Let's say that setting was in Trip A, and i wanted to see my instant gas mileage average from my current drive since turning the car on (Trip Auto), is there a quick way?
