2015 Why did Maintenance Mode start?

As it is elsewhere, it is very cold in Toronto this week. The ICE on my 2015 has run every day for long periods of time over the week. I have burned at least 3 liters and gone over 30km with the ICE running.

So why did Maintenance Mode execute this morning? What was the purpose of the 10 minute MM run given all the exercise the ICE had this past week due to ERDTLT?

ERDTT doesn't get the engine fully warmed up, only gets it warm enough to provide cabin heat. The engine still needs to run maintenance mode to get nice and hot. Every now and then you could put it in hold mode in the winter for your commute and avoid the EMM.

I don't have hold in my 2012, but since my range is so limited in these temps I have no issue needing EMM. Otherwise I put it in mountain mode for a few minutes when it is low to get nice and hot.
