Does a 2009 Prius need to be reprogrammed after a new battery is replaced?


If you disconnect all sources of 12V power to the car a few things will need re-programmed, such as the windows and radio settings. They are all very simple (run the windows up and down, input the desired radio stations, etc.) and there is nothing that will keep the car from operating fine. (I'm assuming you refer to the small 12V battery, not the one that moves the car.)
