Night View Assist PLUS uses infrared technology to improve the driver’s range of vision in the dark and when there is oncoming traffic:

Two separate headlamps illuminate the road with invisible and, therefore, non-reflective infrared light. A windscreen-mounted camera designed to pick up precisely this type of light records what happens in front of the car and sends the image to a display on the dashboard or the instrument cluster. The clear, needle-sharp greyscale image that appears here shows the scene in front of the car, allowing the driver to see pedestrians, cyclists or obstacles on the road at an early stage.
