It's not from opening the door(s). That's just a co-inkydink. It'll happen before or after opening the door. Sit there long enough, & it'll go off before the door opens, sometimes. Jump out quick, & it'll go off after, sometimes. But sometimes, not at all. It just depends on the need for recharge.

Spent some time with my Toyota Service Manager, and he listened and convinced me, as did Tom, that it was the brake accumulation pump, and is a normal function on the Prius. Thanks for all the replys.
