i often sit in my car reading and listening to the radio before i go to work. i have the engine off and am only using the 12v system. about 30 mins later everything shuts off. im wondering if this is just a timer sort of thing or if it shuts everything off when the 12v is getting drained. i usually will turn on the engine at that point for a few minutes thiniking im recharging the little 12v. am i saying this right and whats going on. :?

might be a fault, as it doesnt happen to mine.

Out of curiousity, what were the weather conditions outside when your Prius shut off?

weather does not seem too make a difference and the time before everything shuts down may be more than a half hour. its almost as if its reminding me that im just using the little battery too long.. and just to emphasize its only when im parked without the main abttery being used or the engine.
just curious. does not seem to hurt anything

You could always just turn the car on when you are sitting there. The engine will start for a minute to warm itself up, then shut down. The 12volt will be charged from the propulsion batteries and if needed, the ice will come on. You could also have the heat or A/C on this way. Remember that just because the hybrid system is on, does not mean that the ICE is running.
