Stability control is enabled (ie, controlling under- and over-steer by applying brakes to individual wheels)
Hitting the DSC button once: turns on DTC (Dynamic Traction Control) mode
This mode appears to disable the "helps to keep the vehicle on a steady course" aspect of DSC - the under/oversteer control bit. Traction control is still enabled, and sounds like the car won't engage individual brakes to correct yaw movement. Somehow this is supposed to help with getting/staying moving on unplowed snowy roads, gravel roads, and the like. Probably because in such low-traction conditions, there's so much slippage that DSC would be constantly engaging, to the detriment of actually getting anywhere.
Holding the DSC button for 5-10 seconds: turns on DSC OFF mode
"Stability is reduced." But the manual also says "the DSC system is switched off." So I'm not clear to what degree the nannies are deactivated, but the implication is that both traction and stability controls are effected.
Then there are the driving modes:
ECOPRO, COMFORT and SPORT are known.
SPORT+ isn't clearly described in the manual. "Limited driving stabilization. The driver handles several of the stabilization tasks." It also illuminates the DSC OFF indicator, same as the 5-10 second button press. The implication, in my mind, is that SPORT+ accomplishes exactly the same thing in terms of stability/traction control as the 5-10 second button press. (Whether that's completely off, or just partially off, the stability programs I don't know. I haven't had the opportunity in an obstruction-free parking lot to test these modes.)

I think sport+ is sport plus DTC on. no?
