OK, I got a reply as to how to change the mileage. There is apparently a set of buttons I found them under the cd player, I can just remember 1 button, "menu" I hit this button and something came up asking me if i wanted the mileage in us or metric, i pressed another button and it changed it back to US which I wanted, I also got the interior lights to work which never worked since i bought the suv, I bought this car last August 19th and have yet learned all the things it does. It helps if the car companies would supply a manual like they did way back when, but the almighty dollar comes first. Hope this helps
