Auto start-stop stopped working

The auto start stop doesnt work anymore the button doesnt light up green when i press it, but its not the button problem because it lights up when i press it with the engine off. it was working just fine and suddenly one day it stopped working. does winter have anything to do with it? it gets to about 2 degrees celcius and even lower sometimes if that has anything to do with it. so what may be the problem here?

If the 12V starter battery is weak it might be a cause, if the CLS have an aux battery that is another cause.
