Steve, each time you dab the INFO button it will scroll tho the following
Trip A (I use this as my daily log of miles)
Trip B (I reset when refueled)
Miles to empty (counts down & triggers the 50 mile warning light)
Average MPG (note in US galls), since last reset
MPG bar graph
Timer
and finally a blank screen
after you start the car, whatever you've scrolled too will stay as your display (which you can change en-route)
Thank you Jon, really appreciate the detail here.
It is the 3rd option I had not spotted (Miles to empty), will set this as my 'home screen'.
