Hill Descent Control (HDC)

Operating principle: HDC is a downhill speed control system that reduces vehicle speed on steep descents, helping you maintain better control of the vehicle in these difficult conditions.

Without any intervention on your part, the vehicle moves at a speed slightly higher than walking pace.

HDC can be switched on at speeds up to 35 km/h. When descending a hill, the vehicle speed is reduced to approximately 8 km/h, which is slightly above walking pace, and is maintained at this level.

You can change the speed within the range from 5 km/h to 25 km/h by pressing the brake or accelerator pedal. The speed within this range can also be set using the "+/–" buttons of the cruise control system.

At speeds above 60 km/h, the HDC system switches off automatically.

Switching on the system: Press the specified button – the indicator lamp will illuminate.

When the automatic system is braking the vehicle, the indicator lamp flashes.

Switching off the system: Press the button again – the indicator lamp will go out.

The HDC system also switches off when the speed exceeds 60 km/h and when the ignition is switched off.

Using the HDC system: If the vehicle is equipped with a manual transmission, switch on the HDC system only in first gear and reverse gear, since engine braking is reduced in higher gears.

If the vehicle is equipped with an automatic transmission, the HDC system can be switched on in any driving position of the selector lever.

In case of malfunction: The indicator lamp does not illuminate when the HDC system is switched on, or goes out during operation: the HDC system is temporarily unavailable due to overheating of the brakes.
