What does 'dual' mean on a Haval car?

[LaGia]

Haval car's dual switch is an air conditioning zone control button. Explanation of the dual switch: The presence of this switch indicates that the vehicle is equipped with dual-zone automatic air conditioning, meaning it has two temperature zones. The left and right sides of the front cabin can independently adjust their respective temperatures. Function of dual-zone air conditioning: Dual-zone air conditioning can meet the different temperature requirements of passengers in two different positions inside the car. Independent temperature zones allow for flexible adjustment between different temperature differences. The most common example is when the driver adjusts the cabin temperature to a level that feels comfortable for themselves, but the passenger in the front seat keeps complaining that the set temperature is either too high or too low. In this situation, the dual-zone automatic air conditioning can play its role.
