My reading is stuck at 38.7, and hasn't moved during a 200 mile trip. Does anyone have an idea where to start checking? The fuel gauge is still reading accurately, just the average miles per gallon doesn't move. Any suggestions?
Well that is certainly one way to do it... or you could just hold down the fuel (is it FCD?) button for 3 seconds.To reset the average you need to disconnect the battery. You will also need to reset you clock.
