What does HDC displayed on the car mean?

[EliRose]

HDC on the vehicle stands for Hill Descent Control system, which enables automatic braking when the car is descending steep slopes. Here are the precautions for using the HDC system: 1. The HDC system must be set up before use to ensure the driver focuses on driving. After setting up the HDC system, the driver should release all pedals to avoid interfering with the HDC system's operation. 2. When using the HDC system to descend a slope, the driver does not need to press any pedals, and the vehicle will drive autonomously at a speed of around 8 km/h. During autonomous driving, the driver only needs to steer the wheel. 3. If the HDC system detects a fault, the car's computer display will show the message "HDC-FAULT-SYSTEM-NOT-AVAILABLE". In this case, the use of the HDC system should be stopped, and the vehicle should be operated manually. 4. HDC is an auxiliary system. Do not rely entirely on the HDC system for descending slopes to avoid unexpected situations.
