On my old car there was one button you mushed to reset and start the odometer and I used it quite often. This NEW car has so many steps you have to go through on the computer that you cannot do it while driving. Have to pull over to set it- what a pain. I hate all the technology on this car - too much that is unnecesary. It is so much trouble that I rarely ever use it but I am paying for it every month in my payment!
