A bit of a random question...on the screen between the tachometer and speedometer, you can cycle through various views and one of them in labeled Fuel Economy. When on that view you can move right or left to see two different views of fuel economy. I assumed one was for the current trip and the other was for fuel economy since the user last reset but...a) the fuel economy is the same for both, all of the time and b) when I do reset, by holding the OK button, they both reset. Any ideas on what their differences should be and how best to operate them? PS I know I could read the manual and find out but I don't have it handy at work and being a first time Jeep owner I'm trying to engage more on boards.
