Principle
At blind driveway exits or when driving out of perpendicular parking spaces, road users approaching from the side are detected sooner by the cross traffic warning than is possible from the driver's seat.
General information
Two radar sensors in the rear bumper monitor the area behind the vehicle.
The system indicates approaching road users.
Depending on the vehicle equipment, the traffic area in front of the vehicle is monitored as well.
Two additional radar sensors are located in the front bumpers.
