How to Use Hill Descent Control?
2 Answers
The method of using hill descent control is: 1. Before descending a slope, turn on the HDC switch, then release the brake and clutch; 2. Press the brake or accelerator to turn it off. The function of hill descent control is: By applying a brief braking force to the front axle of the car, it compensates for engine braking, thereby improving the controllability of the car when driving on steep slopes. Precautions for using hill descent control are: 1. Hill descent control must be set before use to ensure the driver focuses on driving. After setting the hill descent control, the driver should release all pedals to avoid interfering with its operation; 2. When descending a slope with hill descent control, the driver does not need to press any pedals. The car will automatically drive at a speed of about 8 km/h. During automatic driving, the driver only needs to steer the wheel properly.
When I first started driving, I often used Hill Descent Control (HDC), which is most suitable for descending steep off-road trails or mountain roads. The first step is to start the vehicle and maintain a slow speed—don’t rush. The second step is to locate the HDC button near the steering wheel and press it gently to activate the system. At this point, avoid pressing the accelerator or brake, as the system will automatically control wheel speed for a stable descent. I believe the most crucial part is observing the road ahead—avoid areas with loose gravel or slippery surfaces in advance, as the system isn’t foolproof. It prevents brake overheating and wheel slippage, but the driver must still stay focused. I always use it in my SUV, saving me from many tense moments. I also advise beginners to practice on flat ground first to get a feel for it. For safety, it’s best to pair it with four-wheel-drive mode, and manually take over during sharp turns or obstacles to avoid accidents. During regular maintenance, check the button and sensors to ensure the function remains operational.
