Floozie

HelloI have had my Skoda Scala about 7 months and filled about with the view at the dashboard for the driver in front of the steering wheel and can't seem to get the true mileage back on I can get the trip milometer on miles-per-gallon everything else but I just can't find the total mileage so looking for someone who can help me get that back on an advise whether the engine needs to be running or off many thanks
