What is the function of the mode button in a car?

[LaDavid]

mode stands for mode, and it is used to switch between multimedia modes. Here is a detailed introduction: 1. Specific functions of the mode button: The mode button is commonly found on multifunction steering wheels and center consoles. It is generally used to switch between radio FM, radio AM, CD, or USB modes. Alternatively, it can be used to switch the car's air conditioning vent modes, typically cycling between foot-level, head-level, and windshield defrost modes. 2. How the mode button works: If the MMI system is playing the radio, CD, or an external audio source, pressing the mode button synchronizes the display between the tachometer and speedometer with the MMI system. Then, by pressing the buttons on the left side of the mode button, you can scroll through songs on the central display screen. Pressing the wheel downward confirms the song selection. Pressing the mode button again returns to normal mode. 3. Specific operations of the mode button: Holding the mode button for ≥1 second triggers a prompt sound from the dashboard, activating the dashboard's operation and enabling the three-button adjustment function on the steering wheel. The dashboard display will show the last-used trip computer interface. Once the three-button adjustment function is activated, briefly pressing the mode button allows you to: enter submenus, select menu items, or make settings. The mode button on the center console operates similarly.
