We were just about to go out for a drive, this morning when our very reliable Prius went 'ping' and then flashed 3 symbols at us. One was the car sign with an excaimation mark. This is the hybrid system warning apparently. Also the power steering sign and finally an electric engine warning.

It'll take a trip down to Toyota tomorrow but until then, any ideas on what might have happened? We've looked in the engine but can't see anything obvious. Not that we would recognise anything anyway.
