Our Brake Assist System (BAS) is designed to help in emergency braking situations. This safety function can substantially shorten your car's stopping distance. The system detects that full braking power is needed and automatically boosts the brake pressure up to the ABS threshold, and continues to do so whilst you keep the brake pedal pressed down. If you then ease off the pedal, the system will reduce the brake pressure again to match the brake pedal's position.
