Hill Descent Control
Hill descent control automatically brakes individual wheels to hold a low, steady speed when driving down steep slopes.
What is Hill Descent Control?
It is common on SUVs and off-road vehicles. The driver controls steering while the system keeps the speed, which can often be adjusted with the cruise control buttons or pedals. It works best together with low range or a low gear. The brake noise and pulsing during operation are normal because the ESC pump is working.
How it works
The ESC unit applies brake pressure to the wheels to stop the car from accelerating down the slope.
Why it matters for your car
Long use can heat the brakes; the system may warn and switch off if they get too hot. It has an upper speed limit and is not meant for normal roads.
