The system consists of a stabiliser system, Roll Stability Control (RSC) that minimises the risk of overturning, for example, during sudden evasive manoeuvres or if the car skids.
The RSC system uses a sensor which registers changes in the car's lateral inclination angle. This information is used to calculate the risk of the car overturning. If a risk exists then the ESC system engages, engine torque is reduced and one or more wheels are braked until the car has regained its stability.
Under normal driving conditions, the RSC system improves the car's road safety, but this must not be seen as an opportunity to increase speed. Always follow the normal precautions for safe driving.
