The Driving Assist Plus feature includes not only Approach Warning and Lane Departure Warning, but also Active Cruise Control with Stop&Go function. This provides assistance when driving on motorways in both critical and stable traffic situations. This option is only available in conjunction with the Navigation System Business or Professional.
The Approach Warning responds in stages. Depending on whether a vehicle ahead brakes suddenly or a stationary object is detected, the reaction ranges from a visual signal to active braking and even a complete standstill. Should the car begin to change lanes unintentionally, the Lane Departure Warning quickly provides a warning by means of vibrations in the steering wheel.
The Active Cruise Control maintains a constant selected speed between 30 km/h and 210 km/h or automatically adjusts to conform with the cars driving in front if the distance control is activated. The Stop&Go function even controls speed down to a standstill, accelerating again easily when the gas pedal is pressed, for example in dense moving traffic.
