Lane Change Assist (LCA) monitors the area behind the vehicle and the blind spot using radar sensors. At speeds between 30 and 210 km/h, the system alerts the driver of a vehicle in the blind spot or approaching quickly from behind via a visual signal from the exterior mirrors. This enhances comfort and safety, particularly when driving on the motorway. However, LCA does not actively intervene in the controlling of the vehicle and can be deactivated at any time.

Optional for all Cayenne models.
