I just purchased a 2004 Ford F-350 Lariat Diesel, with 56,000 miles on it. I am having trouble reseting the overhead counsel (MPG read out). I really want the MPG in real time so I can get the optimum MPG when hauling a heavy load. Trouble reseting the Avg MPG as well. Can anyone help??

Thankx Dru

 

To reset select the mpg reading, press and hold both overhead buttons at the same time. You do not have the option of instaneous, only avg.
