TCS (Traction Control System):

TCS is an anti-slip function which provides improved traction. The control module employs both reduction of engine torque (request to engine management system) and brake application on the drive wheels during TCS modulation.

The rear wheel speed is used as a reference for comparing the speed of the front wheels individually. When one of the drive wheels rotates faster than the rear wheels, the wheel is said to spin. The magnitude of this wheelspin and the speed of the car are decisive to how the system operates. Traction is given priority when wheelspin exceeds a limit value when the speed is lower than 40 km/h. The system then employs brake application first and then engine torque limitation.

The transfer of lateral forces to maintain steering ability is given priority when wheelspin exceeds a limit value at speeds above 40 km/h. The system then employs engine torque limitation first.

A certain degree of wheelspin is always allowed so that the sporty feel and handling of the car will still be retained. This varies with the speed of the car, the friction between the tyres and the road surface and how "aggressively" the car is being driven (position of the accelerator pedal).
