So I have a 2013 C300 with the ECO start-stop feature. I'm trying to figure out what parameters are used in actually enabling this feature. It seems to be really finicky in enabling itself, and some odd things lead to it turning on.
Some parameters I would guess would lead to the feature being enabled:
- Engine Temp
- Cabin Temp + Climate Control Usage
- Driving Style, hard acceleration, etc.
I've observed that hard acceleration definitely turns the feature off. But on the other hand, driving very slowly in Economy mode will not turn the feature on until I have reached a certain RPM for whatever reason. Driving in Sport I see the feature off more than on, but that may be due to my driving style.
Anyone have ideas what may turn the feature on/off? I'd like to get more use out of it, because I find myself sitting at stop lights with the feature off, wishing I could force it on.
