987C.1 Traction Control Off on Icy Roads?

[jcelee]

I live on a hill surrounded by hills. These hills are rarely salted or treated in any way. I'm planning to swap over to winter tyres this weekend but am wandering whether traction control is best switched off on potentially icy roads?

I had a Jag with a reasonably crude TC system which would grab a brake if it sensed any slip making a bad situation (slight slip on ice) a whole lot worse and unpredictable. It would automatically grab a brake without warning in one instance sending 17ft of car very sideways across the road....

Many thanks for your thoughts

Thanks, so we just think PSM cuts power, it doesn't apply brakes?

The issue I've experienced in the past (not in the Cayman yet) was patches of black ice going down hill. The issue with automatic braking here is that it turns a small slip into a much larger and sudden slide.

Am I right to assume then that PSM is smart enough not to jam on a brake when it detects slight loss of traction because of ice?
