What does 'car' mean on a vehicle?

[CodyAnn]

On a vehicle, 'car' refers to the vehicle's onboard computer information, which is used to quickly access the car system settings interface. Pressing this button allows the multimedia central control screen to directly switch to display the car system interface. Within this interface, various vehicle settings can be adjusted, such as driving mode selection, seat and air conditioning adjustments, parking assistance systems, settings, and services. Different buttons on the vehicle have different functions: 1. The SEL button is a menu selection confirmation button, typically located on the multifunction steering wheel; 2. The OK button has the exact same function as the SEL button, with some vehicles using SEL and others using OK; 3. The AC button is the compressor switch, which is the air conditioning cooling switch.
