I bought a Priuc C because of the MPG. My wife has a Lexus and she is able to see how many miles she has left before needing refuel. On my Prius C I put 2 gallons and the cruise range shows 1 mile. Why is the computer not calculating correctly the miles. I tried it several time and get the same results, any input is greatly appreciated.
In my Gen 2, it warned that you might need to add 3 gallons before the computers updated. In my v it warns that you might need to add over 1.8 gallons before the computers update. I do not own a C, but I find this nebulous advice in the owners manual http://www.toyota.com/t3Portal/document/om/OM52B58U/pdf/sec_2-2.pdf (page 13 of the PDF, page 191 of the manual) I can only advise you to wait longer before doing fill ups.
