I seem to remember that those of us with US cars don't have folding mirrors, at least in 2015. We do have the ability to dip the right side mirror when reversing, and I will report that it was -17 C today here, and my right side mirror dipped as usual. However, my blind spot assist didn't work and on other cold days I have gotten a message that my oil level was low, and I should check it the next time I refuel, although I didn't get that message today. When I have checked the oil, it seems ok. I must say that the GLA dipstick is really hard to read.
