Hello I have had a Smart for Four BR453 for 3 weeks. After I had picked up the car, I had fully fuelled it, since about 200 km could be with an average consumption of about 7 liters/100km. After my calculation about 14 liters should be missing in the tank. But now the tank indicator persistently shows all the beams, so fully. Normal or spins the display, because have no desire that sometime ebbe is despite full display…. Furthermore, since I have the Smart has never the Start Stop I know, before one writes now, idle foot from the clutch, certain parameters must fit etc… Does everything just show me in the instrument cluster always the orange crossed-out symbol. Does anyone have tips?
