Our Electronic Stabilisation Control (ESC) detects critical situations at an early stage, and takes action to stop skidding and help bring your car safely back under control. It uses sensors to monitor the progress of your wheels. If they start to slip, ESC takes over by applying the brakes to one or more wheels and reducing engine power if necessary. ESC links to your car's electronic systems, such as the anti-lock brakes (ABS) and engine braking control (EBC). It has sensors on the wheels and steering wheel, plus a yaw movement sensor. The new Comfort Braking Assistant, the latest form of Hydraulic Brake Assist (HBA), helps even unskilled drivers reduce braking distance by around 25 per cent. The ESC plays a further role, using electronic differential lock and traction control to help correct oversteer, understeer and loss of stability of the car. The result is optimum traction when rounding bends.
