The manual states that the car will auto turn off after one hour of being kept in 'run' mode (I think that is what it is called). It says while in 'ACC' mode only certain accessories are available. Since the pacifica has a battery that is around 12x that of the prius, will it run heat/ac and charge electronics while in ACC mode, since in run mode it will timeout? Then the engine will turn on periodically to recharge the battery, like the prius? Hope this makes sense.
