What do AUTO and DUAL mean?

[LeJuliana]

AUTO refers to the automatic air conditioning, while DUAL is the air conditioning zone control button. In automatic mode, regardless of whether cooling or heating is selected, the system can cool when the temperature is above 25 degrees and heat when it's below 25 degrees. DUAL is the air conditioning zone control button. After pressing the DUAL button, you can set the air conditioning temperature for the driver and passenger seats separately. Once the desired temperature is adjusted, turning off this button will allow the automatic air conditioning to regulate the temperature according to the set values. Below is an introduction to air conditioning maintenance: 1. Comprehensive air conditioning inspection: When using the air conditioning for the first time in summer, you should first check the air conditioning system, such as inspecting the refrigerant through the reservoir, checking if the air filter is too dirty, and whether there are any foreign objects in the radiator. 2. Pay attention to air conditioning cleaning: The air filter should be replaced regularly; otherwise, the air conditioning may produce a musty odor. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning.
