Hill Descent Control*
The function for assisting when driving downhill (HDC1) is a low-speed function with increased engine braking. The function makes it possible to increase or decrease the vehicle's speed on steep downhill gradients by only using the accelerator pedal, without applying the brakes.
In vehicles equipped with drive mode control*, the function is included in the Off Road drive mode.
HDC is designed for driving on rough roads at low speeds and downhill gradients with slippery or otherwise difficult road surfaces. The driver does not need to use the brake pedal but can instead focus on steering.
Warning
HDC is only intended to be a supplementary braking aid and it does not function in all situations.
The driver is always ultimately responsible for operating the vehicle in a safe manner.
Function
Hill Descent Control allows the vehicle to move forward or backward at very low speeds assisted by the brake system. The driver can increase the speed by pressing the accelerator pedal. When the accelerator pedal is released, the vehicle will return to very low speed regardless of how steep the hill is and without the brakes needing to be applied. The brake lights will illuminate when the function is activated.
The driver can brake to stop or slow the vehicle at any time by depressing the brake pedal.
HDC is activated along with Low Speed Control (LSC2), which facilitates and improves traction and control on rough and slippery surfaces. The system is intended to be used at low speeds, up to approximately 40 km/h (25 mph).
To keep in mind when using HDC
- If the function is switched off while driving on a steep downhill gradient, braking effect will be gradually reduced.
- HDC can be used in gear positions D and R, and in manual gears 1 or 2.
- It is not possible to manually shift to third gear or higher when HDC is active.
