Just a thought. Has anyone actually tried doing the change from Miles to Kms or vice versa. If so maybe they could talk me through it. Here's hoping!
Yes. Jeff's link describes it. The Fuel Consumption Display cycles round 3 displays each time you press it. Live fuel consumption (updates every 15 secs); Average fuel consumption; nothing.
Holding the button down for 2 secs on 'Ave' fuel consumption will reset the average. On mine, this is shown as miles per litre. But other european models show km/l or l/100km
Holding the button for 2 secs when you have cycled the display to nothing will change the distance units from miles to km and back.
I usually keep mine on Average, and reset it every time I fill up.
There is no option for changing from litres to gallons that I have found. Both my UK models have shown miles per litre.
