I did not know that autostop turned on or off based upon outside temperature. I thought it did turn itself on or off based upon your climate controls. If your AC had a demand for cool air it would turn off autostop. If the heat was on it would disengage. Apparently from what you have written it wasn't actually based upon climate controls but outside temp. Interesting.Before buying my 2021 trailblazer I had a 2017 Chevy Cruze. The auto stop feature on the Cruze would disengage when the outdoor temp was below +5c I think, plus or minus a few centigrade. My trailblazer seems to auto stop well below zero. Is this normal?
I read an interesting article on this subject:Do you think that stopping the engine at intersections is good? And you know that starting the engine is a critical situation and the wear of the engine at startup is much greater than when it is running evenly. When I was studying, we were told about this in the discipline of RELIABILITY. And it really is! To put it another way, then one start of the engine (and indeed any device) is equivalent to a certain time of operation of this device in normal mode. Of course, I can't say how many minutes of engine operation is equivalent to starting it, but our reliability experts calculated that turning on and off a color lamp TV once is equivalent to 2.5 hours of its normal operation. Thus, it makes no sense to turn off such a TV for less than 2.5 hours. This is from the point of view of its technical resource. So the same thing happens with the car. Engine wear is stronger at startup than at idle. And if you stop it at every intersection, then its resource is consumed more than if you didn't stop it. Yes, of course you save fuel, but at the same time you will need to repair the engine on your car earlier than if you did not have an automatic stop function. In this regard, on my car, I turn off this fugktion every time I go. And I have a question for my colleagues. Maybe someone knows how to disable this function so that the car remembers that it never needs to be used??
A wonderful device. Except for the cost.....Try this site. Not endorsing.
