Hello, I have a 2017 Titanium Fusion Energi. Recently I filled up with a new tank of gas and wanted to reset the instantaneous MPG (shown in the Empower and Engage displays). I found where to reset and did so, but now the MPG continuously shows 999.9 MPG, even after all battery power has been used and Hybrid/gas has kicked in. What did I do wrong? Or should I do something else to get it to start "calculating" again? Thanks, David
