Hyundai Ioniq Hybrid - no 12v battery?

I saw a Hyundai Ioniq Hybrid on my way home today and it looked fancy, which of course made me curious enough to look it up when I got home. One of the first things I saw in the Wikipedia article on it was that it doesn't have a 12V battery. Does anyone know what it would use as a replacement? I thought it was required by federal law that the high-voltage battery be completely isolated when the vehicle was turned off (hence why even the Tesla has a 12V battery), but I don't know how that would work if there's no low-voltage battery in the vehicle. The lights, locks, etc. wouldn't work if the vehicle was off, and the Start button would have to mechanically connect the high-voltage battery relay when pressed.

I'm wondering if maybe the article cited as the source for that information on Wikipedia is not entirely accurate in saying it doesn't have a 12V battery and they're using something like a smaller Li-Po or Li-Ion 12V battery (which my dad's motorcycle has instead of a lead-acid or AGM now).

One of the features that has to happen by Federal standard is the Emergency Flashers must operate for a given period of time (not sure, but I think it is 12 hours). Usually these are operated by the 12v system, so what ever source is used has to live for that period of time.
