Hi. The average Mpg gauge shows a blank space where the mpg should be and my average speed gauge says my average speed is 1mph. The owners manual doesn't say much about the gauges. Anyone have the same issue? Any solutions that worked?
If you put it on Trip A it will show you totals from last reset (hold trip in a few seconds). When the power is turned off after a drive the display will show details for that drive. If you don't move and turn the power on and off it will show 1MPH and blank MPG
On my 2013 Prius Three, I reset Trip A and the "Avg Speed" figure seems stuck on about 22 mph, which is not even close to what it should be. Does anyone have an idea of what is going on, or are you having the same problem?
