The predictive efficiency assist helps the driver to drive with anticipation and therefore helps to save fuel. The system accesses predictive trip data (including speed limits, inclines and the radius of curves) from the navigation system*. Information from the camera-based traffic sign recognition* is also applied to recognize traffic signs page 104. The messages displayed depend on the navigation data* being up-to-date and the correct identification by the traffic sign recognition*.
When adaptive cruise control* is switched off, the predictive efficiency assist only provides notifications without controlled interventions. When adaptive cruise control* is switched on, the system responds to upcoming situations automatically. Predictive messages appear in the instrument cluster display to show the driver the appropriate time to coast when a situation ahead requires you to drive at a lower speed. The messages are only shown if the cruise control system* or adaptive cruise control* is switched off.
The adaptive cruise control system is a combination of speed and distance regulation. It assists the driver by both regulating the speed and maintaining a distance to the vehicle driving ahead, within the limits of the system. If the system detects a vehicle driving ahead, the adaptive cruise control can brake and accelerate your vehicle. This increases driving comfort during long trips on highways and in stop-and-go traffic (automatic transmission*).
