The braking system increases driving comfort and safety.On one hand it helps to perform critical braking manoeuvres with the basic function of the ABS anti-lock braking system while convenience functions make coping with daily driving situations easier on the other.
By priming the brakes the brake linings are already applied should the driver takes his foot abruptly off the accelerator. The valuable time won as a result shortens the brakes' response time and can thus reduce the stopping distance.
The HOLD function relieves the driver when stopping at traffic lights or in stop-and-go traffic by preventing unintentional rolling back of the vehicle. If the brake pedal is firmly depressed for a short time, it then maintains the braking pressure, allowing the driver to take his foot off the brake. The function switches itself off again automatically as the car moves off.
The system also intervenes to support the driver on uphill gradients, thereby helping to make the journey more relaxed. The Hill-Start Assist function prevents the vehicle from rolling back when moving from the brake to the accelerator pedal
And finally, the brake drying function provides a further boost to safety: In wet conditions, short braking impulses, unnoticeable to the driver, ensure that the water film which forms on the brake discs in wet conditions is removed and the response time of the brakes can be considerably shortened.
