Electronic stability control (ESC) - general
The activation of the ESC system during braking may be noticed as a throbbing sound. The car may accelerate slower than expected when the accelerator pedal is depressed.
- The stability system ESC is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
- ESC is not a substitute for the driver's attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
The ESC system consists of the following functions:
- Active Yaw Control
- Spin Control
- Traction control system
- Engine drag control - EDC
- Corner Traction Control - CTC
- Trailer Stability Assist - TSA
Active Yaw Control
The function checks the driving and brake force of the wheels individually in order to stabilise the car.
The function prevents the driving wheels from spinning against the road surface during acceleration.
Traction control system
The function is active at low speed and transfers power from the driving wheel that is spinning to the one that is not.
Engine drag control - EDC
EDC (Engine Drag Control) prevents involuntary wheel locking, e.g. after shifting down or engine braking when driving in low gears on slippery road surfaces.
Involuntary wheel locking while driving can, amongst other things, impair the driver's ability to steer the car.
Corner Traction Control - CTC*
CTC compensates for understeer and allows higher than normal acceleration in a bend without wheelspin on the inner wheel, e.g. on an arcing motorway entrance road to quickly reach the prevailing traffic speed.
