exactly the problem ! ! ! Remember we are only talking about the Prius Even in the city you should do better than that, I remember hills in Athens. When coasting, ALWAYS keep your foot slightly on the brake pedal. Including downhill. When parked at a taxi stand, keep the car on and in ready, and windows closed! that way it is always warmed up. Sit inside, with the AC on, on LOW, be comfortable, and your battery will be comfortable. I will bet that you will have 4-6 bars purple and maybe even some green bars. Do not charge the Traffic light, coast, let it turn green before you there. Mostly the Prius responds best to conservative driving. Let the other idiot race to the light, always follow speed limits, EXACTLY. Remember Prius likes 41 MPH the best ! about 65KM/Hr. :cheer2: Your passengers will be happier and you will save fuel. Put a glass of water on your dash, 3/4 full, secure it. NOW drive without spilling a drop!
