The function is adapted for off-road driving and driving with a trailer at low speed, up to approx. 40 km/h (25 mph).
Low speed control prioritises low gears and traction. If the car is all-wheel drive, the motive force is distributed evenly in order to provide as good traction as possible on all wheels and to reduce the risk of wheel spin. The accelerator pedal is less responsive in order to facilitate traction and speed control at low speed.
The function is activated together with hill descent control, (HDC2) which means that speed down steep hills can be controlled with the accelerator pedal, reducing the need to use the brake pedal. The system facilitates a low and even speed while driving on steep downhill gradients.
