The 7 Series and the S-Class also have night-vision features. The BMW uses a thermal-imaging camera mounted in the front bumper. The body heat of humans and animals crossing your path or on the side of it shows up as bright spots on the display through the iDrive screen on the dashboard. Adding to this safety feature is a new pedestrian-detection system that highlights potential hazards on the screen with bright yellow triangles and audible warnings. The Benz uses a near-infra-red camera, which requires a special set of lights in the headlamp cluster to produce a luminous image on the instrument screen. All relevant information is displayed on the COMAND's eight-inch screen, which sits in the driver's central field of vision. This way you always have your central settings before your eyes. The Audi offers a radar at the front, thermal-based night-vision camera hidden in the right-most ring of the grille's four-ring badge and rear-facing radar. All you need to do is select all the driver-assist tools through the MMI and then the adaptive cruise determines whether the car in the rear is too close for comfort or if the adjacent lanes are clear while overtaking. It also keeps a tab on whether you're changing lanes, if there is a crossing coming up using the navigation system and even if the car in front has a turn signal on (using the front camera); then it adjusts your car speed accordingly. There's more. The systems offer collision mitigation, lane departure warning and stop-go active cruise and infra-red night vision that recognises pedestrians and cyclists and alerts you through the display between the speedometer and tachometer, if they encroach upon your path. Scary technology, but doubly reassuring for all the passengers of the car.
