The 'scan' on a car means scanning, which refers to searching for radio stations and then stopping. Generally, only older car models have a physical 'scan' button. It searches for radio stations and stops immediately after the search is completed. When pressed in CD playback mode, the display will show 'SCAN', and the music will start scanning from the next track of the currently playing song, playing a few seconds of each track before moving to the next one in a loop. When the user hears a track they like and presses the button again, the audio system will start playing from that track. Introduction to other car buttons: The buttons on a car are functional buttons for various configurations. These buttons are usually concentrated on the center console and surrounding areas for easy blind operation and quick access by the driver. The car's center console is likely the area with the most buttons, integrating air conditioning controls and multimedia controls. Some high-end models may use LCD touch screens to replace these buttons. Generally, the multifunction steering wheel integrates audio controls and dashboard information center controls on both sides. Some other configurations may also be placed on the steering wheel. Behind the steering wheel, car light controls and wiper controls are integrated on separate levers. Some models may also have adaptive cruise control.
