How to Use the Hill Start Assist Function in a Car?

[VonValentina]

The method to use the hill start assist function is: when the vehicle's gear is not in P (do not put it in P, other gears are acceptable), press the brake pedal firmly until you hear a "beep" sound, at which point the hill start assist system activates (working time is two seconds), and the brake lights will illuminate to automatically generate braking force. When starting on a steep or slippery slope, if the driver switches from the brake pedal to the accelerator pedal, the vehicle may roll backward, making it difficult to start. To prevent this, the hill start assist control temporarily applies braking force to all four wheels to prevent the vehicle from rolling back. When the vehicle is on an uphill slope, at the moment the foot leaves the brake pedal to press the accelerator, the HAC system will automatically maintain brake fluid pressure for 2 to 3 seconds, preventing the vehicle from rolling back due to gravity and inertia.
