Hill Start Assist serves to stop your vehicle from rolling back while on a hill by automatically operating the brake system for about 3 seconds, even if you release your foot from the brake pedal. Hill-start assist works by sensing the car is on an incline and holding the brakes for a few seconds, even after the handbrake has been released. In these precious nanoseconds, the clutch's biting point is found and the car can move forwards with no risk of rolling back. How hill-hold control works.
