Are user settings stored in non-volatile memory?

The GV70 has a ridiculous number of user settings. The most recent one I came across is setting the proportion of seat heat going to the back and the bottom. Are all of these settings stored in non-volatile memory so you don't lose them if you change the battery?

Are you worried that you might chill your bottom if your battery dies?
