It means that with the windows closed, the air conditioning's ventilation achieves the function of exchanging indoor and outdoor air, refreshing the indoor air. How to use car air conditioning: If your car does not have an automatic speed adjustment device, then the car air conditioning system cannot be turned on first. The best practice is to start the engine before turning on the air conditioning when using it. Automatic transmission: For automatic transmission cars, when the driving speed reaches 120 kilometers, you should not turn on the air conditioning. Additionally, manual transmission cars should turn off the air conditioning at 110 kilometers. This can reduce the working pressure on the air conditioning and prevent shortening its lifespan.

The DUAL button on the Haval H6 refers to the independent control switch for the dual-zone climate system. My family owns a third-generation Haval H6, and this feature is particularly practical—when the button light is on, I can set my driver's side to 18°C while my wife on the passenger side sets hers to 26°C, with both vents operating at separate temperatures. This means no more arguments about the AC temperature during family trips. Normally, my wife feels cold while I prefer it cooler, but now we can each control our own zones, with even the rear seats having independent temperature settings. However, during long drives, turning off DUAL and switching to single-zone mode increases airflow. The specific button is located on the central control AC panel, marked with the letters 'DUAL'.

Many new car owners don't quite understand this feature. The DUAL mode essentially allows separate operation of the driver and passenger climate zones, enabling independent temperature and airflow settings for each side. Think of it this way: there are temperature sensors on both the left and right sides of the steering wheel, functioning like sentinels that monitor their respective areas. When you press the DUAL button on the center console and the indicator light comes on, adjusting the passenger-side temperature knob won't affect the driver's temperature settings. However, it's recommended to turn off DUAL mode during winter heating, as this allows warm air to circulate more quickly. Practical tests have shown that in sub-zero conditions, using dual-zone mode can reduce heating efficiency.

This feature is a godsend for temperature control enthusiasts! After picking up my car last year, I spent quite some time figuring out that the DUAL button is the switch for dual-zone climate control. When illuminated, the temperature knob on the left side of the steering wheel only adjusts the air vent temperature for the driver's side, while the right knob controls the passenger side. Last week during a road trip with a friend - she prefers it cold while I like it warm - we each adjusted our own zones and stayed comfortable throughout the journey. Remember, the indicator light on the button must be on for dual-zone control to activate, otherwise adjusting the passenger side temperature will alter the driver's settings too. While single occupants might find this feature redundant, it's incredibly practical when traveling with family.

Specifically, it's the dual-zone climate control switch. A few days ago, my sister just picked up her new car and asked me why adjusting the temperature on the passenger side didn't work. Actually, she forgot to press the button labeled "DUAL" on the center console. After pressing it, the indicator light turns on, and only then can the temperature control knobs for the driver and passenger be adjusted independently. The principle is that there are two temperature sensors in the car, each collecting temperature data from their respective seating areas. A practical scenario is when the driver needs warm air to defog the windshield while the passenger prefers cool air—it's especially convenient then. Turning off the dual-zone mode also has a benefit—the air conditioner operates at full power for a single zone, warming up the air about 30% faster.

This is Haval's unique dual-zone independent air conditioning switch. When activated, the driver and front passenger can set different temperatures: you can enjoy 23°C warm air while driving, while your front passenger can still have 18°C cool air. The small illuminated button on the AC panel is the switch, which displays blue backlighting around the knobs when activated. Practical tests show it works best during seasons with large morning-evening temperature differences - your passenger won't need to readjust when morning warmth gives way to afternoon heat. Just remember: turning off dual-zone mode before starting the AC allows faster cabin heating and better fuel efficiency. Overall, this feature doubles everyone's comfort.
