Auto-darkening Work In The Cold?

I just got my first auto-darkening helmet, from Harbor Freight for about $40. In spite of the price it is adjustable in various ways and seems to work fine. I think it will really help me improve my very limited welding skills.

Anyway, to the question: The manual gives an operating temperature range of 131 to 23 deg (F). It's Feb. in Minnesota and gets colder than that. What if anything will happen if I try to use it in temps of, say, 15 deg?
