I've been driving in winter conditions in the mountains and there were situations in which there was some slippage.
I know than in general with other cars when the ESP is activated a light in the dash board tells you.
Does the DSC light turns on when it kicks in ? I've never seen it in two years...

Yes, it does. You are not trying hard enough
If you turn DSC off, the light on the dash stays on. Phil

Thought the same as the old BMW the DSC blinked a lot during slippery winter conditions
The Freely is another thing and has to be very slippery to get a DSC blink and as phil says, you have to try hard to make it lock inn.  2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

Strange.... I guess I'll have to try harder.
