Is the downhill descent control of Song Pro automatically activated?

Song Pro's downhill descent control is not automatically activated; it requires manual activation. Below is relevant information: Introduction: The downhill descent control system, also known as the slope control system, is commonly found in off-road SUVs. Its full English name is Hill-Descent-Control, abbreviated as HDC. It is an automatic control system applied during downhill driving. Principle: The working principle of the HDC system is to coordinate the brakes and ABS, allowing the vehicle to maintain a low speed and not lose traction when descending steep slopes. Generally, the HDC system sets a speed limit to enable the driver to control the vehicle more comfortably.
In my experience driving the BYD Song Pro, the hill descent control feature doesn't activate automatically—it requires manual operation. Typically, before driving down a steep slope, you need to press a button or activate it via the touchscreen in advance. The system then takes over brake control to help maintain a stable speed on rugged terrain. I think this design is quite good because if it were automatic, it might accidentally engage when not needed, causing interference. Manual control offers more flexibility—use it when you want, don't when you don't. This feature is especially practical for beginners, preventing wheel slippage or loss of control during descents. I recommend familiarizing yourself with the button location before each trip so you won't fumble in critical moments. Overall, it's not smart enough to activate automatically, but the manual approach ensures both safety and convenience.
