Professional navigation system
If the vehicle is equipped with a Professional navigation system, the system adapts the acceleration and deceleration behavior of the vehicle to the road on which you are currently driving.
To ensure that the system has the latest information on the course of the road, use the most recent version of the navigation data.
If the vehicle position is unknown, e.g., if you have left the region covered by the map, the navigation system ceases to influence vehicle behavior.
