    After nearly 10 years driving the Gen ll Prius, I must say that I am not coping too well having changed it for the Gen III - often press the 'Start' button instead of 'P' Toyota having changed the layout and too many buttons and options!

    Bit disappointed to see the mpg has dropped from my normal 58 - 60 mpg to around 51mpg and wondered if the hybrid battery is charging properly. When braking going downhill, the CHG on the display moves right over to the left, but when just going downhill without braking the CHG barely moves more than a 1/8". Lot of hills where I live. Also, the battery never seems to fully charge, although Dr.Prius indicates it is as good condition and similar to the Gen II.

    Any thoughts would be appreciated.

    what year and how many miles?

    the battery sounds fine, but there are a million other things that can cause lower mpg.
    how long have you owned it?
    how many miles have you driven at 60mpg, and how many at 50?
    do you measure mpg when you fill the tank?
    has anything changed in your driving route?
    had any work been done on the car just before the change?
