Brake assistant
When you apply the brakes rapidly, this system automatically produces the maximum braking force boost. It thus helps to achieve the shortest possible braking distance during full braking.
This system utilizes all of the benefits provided by ABS.
Do not reduce the pressure on the brake pedal for the duration of the full braking.
