What does 'hold' mean on a car key in Chinese?

[DiMariana]

The DUAL switch on a car is an air conditioning zone control button, usually displayed together with AUTO. Here's what the DUAL function does: 1. Temperature adjustment: DUAL indicates dual-zone, allowing separate adjustment of the air conditioning temperature for the driver's seat or the passenger seat, meeting the different temperature requirements of passengers in two different positions inside the car. Independent temperature zones can be adjusted and switched freely between different temperature differences. 2. Automatic air conditioning: AUTO means automatic air conditioning. When pressed, the air conditioning will automatically adjust the temperature and airflow based on weather, road conditions, etc. 3. Other information: The DUAL switch may vary in different car models. Most models now call it the SYNC switch, and its working principle is roughly the same as the DUAL switch. Not all car series use the name DUAL; some models use the SYNC button for adjustment. The name of this button may differ depending on the car model, but the function is basically the same.
