HI all, how do i turn this off, i only want one mpg display, as i cycle through the option via the stalk , i get cons1 cons2 timer temp etc, is there no way just to have one consumption? dug out the handboook but no joy, also read that runnin the car with less than enough gas that would cover 30miles can be harmful? i have done it many times before and got to last 14miles of the thak before filling up with no issues, any ideas much appreciated
