Automatic Stability Control (ASC).

On uneven or slippery road surfaces the Automatic Stability Control (ASC) system ensures you can accelerate out of each bend safely and with maximum traction.

Automatic Stability Control (ASC) is an element of the Dynamic Stability Control (DSC) system. It prevents loss of traction on the drive wheels when setting off, when accelerating out of curves and in other critical moments. When one wheel has good traction but the other is on a slippery patch of road, the wheel with less traction is braked until it is again able to gain a grip on the road surface.
If both wheels lose traction, the engine management system also intervenes and reduces the power output, which significantly reduces the danger of the rear of the vehicle skidding out. The entire process takes place in milliseconds.
Thus ASC quickly brings the vehicle back to stability and restores traction. Drivers wishing to attain a degree of wheel slip, for example when aiming to have a certain amount of "drift", can disengage ASC if desired.
