I'm sure the question has been asked many times and if there is the definitive thread, please lead me to it. Can I get a SIMPLE explanation of the yellow bars on the engery screen. I surmise that the vertical one is a current bar graph of 'instant' mpg. But I'm lost with the horizontal one showing 'minutes' and that some bars show the car icon and other don't. How can I manage it? What is it telling me about my driving tendencies? What should my 'goals' be as I watch it? Help educate this 10 day owner. Thank you.
