Adaptive cruise control
Adaptive cruise control is a safety system that maintains a safe distance between you and the vehicle in front of you when you’re using cruise control. The system uses radar sensors, a camera and sometimes even a laser sensor to detect spacing between you and the vehicle in front of you. It feeds that data into a computer to detect spacing and the speed at which you or the other vehicle is increasing or decreasing the space. The cruise control responds by slowing or speeding up your vehicle.
The sensors are usually installed in the grille area and require special calibration whenever a repair is made to the bumper, grille or radiator.
