How to Activate the Hill Start Assist Function?

[VanWyatt]

The method to activate the Hill Start Assist function is: 1. When the handbrake is not engaged, the gear lever of a manual transmission vehicle should be in the neutral position; 2. For automatic transmission vehicles, the gear lever should be in a position other than P; 3. The accelerator pedal is not pressed; 4. The vehicle is in a stationary state; 5. Press the ESP button. The working principle of the Hill Start Assist function is: When starting on a slope, as the foot moves from the brake pedal to the accelerator, the HAC system automatically maintains brake hydraulic pressure for 2 to 3 seconds, preventing the vehicle from rolling backward. Once the accelerator is pressed, the HAC system gradually reduces brake force. If the accelerator is not pressed, the HAC system's automatic brake control will also end after 2 to 3 seconds.
