What does dual mean in a car?

The dual in the car refers to the air conditioning zone control button. By pressing the dual switch, you can independently adjust the temperature of the air conditioning for either the driver's seat or the passenger seat. Below is an introduction about dual: 1. Using the dual switch can meet the different temperature requirements of occupants in two different positions inside the car. The independent temperature zones allow for flexible adjustment and switching between different temperature differences. 2. Zone air conditioning means that different temperature areas within a single cabin can be independently adjusted. Dual-zone air conditioning refers to the ability to independently adjust the temperature on the left and right sides of the car, while quad-zone air conditioning means the temperature for the front and rear rows, as well as the left and right sides, can be adjusted separately, meaning there are four zones with independently adjustable temperatures. 3. Air conditioning zoning is based on load analysis, dividing the entire air conditioning area into several temperature control zones according to the differences in air conditioning loads. The purpose of air conditioning zoning is to enable the air conditioning system to effectively track load changes, improve indoor environment, and reduce air conditioning energy consumption.
I find the dual function in the car particularly practical—it's essentially the dual-zone climate control for the vehicle's air conditioning. My passenger and I can each set our own preferred temperatures. For example, I prefer cooler air at 22°C, while the person next to me might set it to 24°C, so neither of us has to compromise. To use it, simply press the Dual button on the AC panel, then adjust the temperature knobs separately—the air vents will deliver air to each zone independently. This feature is a lifesaver on long road trips, eliminating arguments over temperature. Higher-end models even offer multi-zone control, allowing rear passengers to adjust settings independently. However, if you're commuting alone, turning it off can save some battery.
