Seat White Indicator Lights - Hill Descent Control (HDC) Indicator Light
It lights up white. Hill Descent Control is active.
It lights up grey. Hill Descent Control is not active. The system is switched on, but is not adjusting.
After starting the descent of a slope below 30 km/h (18 mph), speed is limited to a minimum of 2 km/h (1 mph) and a maximum of 30 km/h (18 mph). When appropriate, the driver may increase or decrease the speed within the limit by pressing the accelerator or the brake. At this point the function is interrupted and, if necessary, it is then reactivated.
Even so, it is imperative that the surface guarantees sufficient adhesion. For this reason, the Hill Descent Control will not fulfil its function when, for example, descending a slope with a frozen or slippery surface.
