Hello... Recently I found that my Prius estimated Km to refuel decreased dramatically!!! 1/3 tank and it says 38Km to go and full tank says 718 Km !! Any idea? Could be the 12V battery It used to be more than 1000 Km as estimate?
very possible. i wouldn't worry too much, those estimates are suspect. how old is the 12v? do you have a volt meter to test it?
