My AutoStop was working tonight, even though the Civic's Temperature Gauge showed 1 Degree and the Climate Control was set to HI (AC was turned off). It would stay in AutoStop for up to 45 Seconds, then the engine would come back on. This worked only after the engine temp reached near normal (a long time...). But I was surprised that it worked at all since I believe the manual said it would not work below 10 degrees or if the fan speed was on high, which it is when the Climate Control is at Max.

Of course, the cold weather is causing low mileage...FE is showing 39.5 MPG, lower than at any time in four tanks after 350 miles. I also noticed that it is very difficult (impossible?) to get it into cylinder shut off mode with electric assist at any speed...can't do it anywhere that I can when the temps were up around 30 degrees. But, I can't complain...it's still better than the Sub (13 MPG in this cold weather).
