Ok i've had my prius for 3 days now and love it! I know that there are certain sounds or noises that sometimes come from the ICE or electric engine when just starting or shutting down. I've read that they're normal. But could someone explain what each of the different noises or sounds mean? I read it somewhere on the Yahoo forum way way back, but cant seem to find it now. I just need to explain it better to my wife so she wont worry about it. Manual says it'll be from the coolant system, hybrid battery, brakes... but they dont specifically say what kind of sound.

Thanks!
