Should DUAL be turned on when using the air conditioner?
2 Answers
When using the car air conditioner, the DUAL function can be turned on or off according to personal needs. The usage method of the car air conditioner is as follows: Distinguish colors: The blue button on the left side of the car represents cold air, while the red one represents warm air, and the middle one represents moderate temperature; Rotate the knob: To turn on the cold air, adjust the left knob towards the blue area. When warm air is needed, adjust it towards the red area, then press the AC switch. The middle button controls the fan speed, and the knob on the far right adjusts the mode, which can be set to blow air only to the feet, hands, or windshield, or both sides simultaneously; Identify temperature: The white line on the left adjusts the temperature. If it feels too warm, adjust it to the middle. When the air conditioner is not in use, simply turn off the middle fan.
I have ten years of driving experience, and whether to turn on DUAL when using the air conditioning depends on the situation. If I'm alone in the car, I simply turn on the air conditioning without DUAL, as the system defaults to unified temperature control, which is hassle-free and energy-efficient. However, if there's someone in the passenger seat with different temperature preferences—like being more sensitive to heat or cold—I activate DUAL for dual-zone adjustment. This creates a more harmonious atmosphere in the car, avoiding temperature-related disputes. DUAL mode does consume slightly more fuel, but the impact is minimal. The key is to keep the temperature difference within a few degrees. It's good practice to check the air conditioning status when starting the car to maintain system stability. Car air conditioning is designed to adapt to various needs, so use it flexibly. There's no need to activate DUAL every time—it varies from person to person.
