Does anyone know if there is a break-in period for a new Prius? Is there a maximum speed a new Prius should be driven for a given period of time? Should the speed being driven vary while breaking the engine in? I am picking a new Prius up within the week and the lady I bought if from said she didn't know of any break-in period. Hopefully, this is the case as I'm going to have to drive the vehicle over 500 miles to get it home.
