The Driving Assist Plus feature (only available with Automatic Transmission Steptronic) includes not only Approach Warning and Lane Departure Warning, but also Active Cruise Control with Stop&Go function. This provides assistance when driving on highways in both critical and stable traffic situations.
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.
