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

[StBradley]

Automatic transmission cars: When the vehicle's gear is not in the P position (do not put it in P, any other gear is fine), press the brake pedal firmly until you hear a beep. At this point, the hill start assist system activates (working for two seconds), and the brake lights will illuminate, automatically generating braking force. Manual transmission cars: When starting on a steep or slippery slope, the system maintains braking for about three seconds, allowing the driver to smoothly transition from the brake to the accelerator pedal. If the car has this function, no setup is required—it's all automatic. Below is how the hill start assist system works: 1. When the vehicle is on an incline, the moment your foot leaves the brake pedal to press the accelerator, the HAC system automatically maintains brake fluid pressure for 2-3 seconds, preventing the vehicle from rolling back due to gravity and inertia. 2. When you press the accelerator, the system gradually reduces braking force. Once the HAC's brake control ends, the vehicle moves forward smoothly as you accelerate. 3. If you do not press the accelerator, the HAC's automatic brake control will also end after 2-3 seconds, so you can take your time to press the accelerator.
