    the car will go into a "sleep mode" to conserve power... also this car may be equipped with an IBS (or intelligent battery sensor), that will monitor the state of charge and age of the battery, as the vehs state of charge gets lower and/or the battery gets older the length of time that these will stay on gets shorter. not sure what year it was off the top of my head that they implemented that.
