Should the car DUAL button generally be turned on?

This button is the car air conditioning's dual-zone temperature adjustment button. If you want to adjust the temperature in separate zones, you can press this button. If you do not want to adjust the temperature in separate zones, there is no need to press this button. Below is relevant information about the DUAL button: 1. The DUAL button in a car is the dual-zone air conditioning adjustment button, also known as the dual-zone air conditioning button. This button is only present in cars equipped with dual-zone automatic air conditioning. Additionally, not all car models refer to this button as DUAL—some models use the SYNC button for adjustment. The name of this button may vary depending on the car model, but the function is essentially the same. 2. When the DUAL switch is pressed and the indicator light turns on, you can individually adjust the air conditioning temperature for the driver's seat or the passenger seat. After adjusting to the desired temperature, turning off this button will allow the automatic air conditioning to regulate the temperature according to the set values.
