Guilliman: The car reports 7.7kWH per KM and this would probably have been since the first owner.
You can reset that. whilst that screen is displayed on the dash, hold down the dot button (next to the squares button) until it blanks out. 7.7km/kWh is pretty high. My best average over a month in summer is about 7.3km/kWh. Last Christmas we drove from Warkworth to Eltham and on that trip with highway driving it was more like 6.3km/kWh.
