How to Use a Manual Car Air Conditioner?

Generally, 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 a moderate temperature. The middle button controls the fan speed, and the one on the far right adjusts the mode, allowing you to switch between blowing air to the feet, hands, windshield, or even using two modes simultaneously. The white line on the left adjusts the temperature. If it feels too warm, you can set it to the middle. To turn off the air conditioner, simply switch off the central fan.
Manual air conditioning operation is quite straightforward, I've been using it for years. After starting the engine, the first step is to adjust the temperature knob, usually turning it towards the blue section for cold air, adjusting according to the weather—turn colder on hot days. The fan speed knob controls the airflow, from low to high, just test the feel. The mode knob selects the airflow direction, commonly used for face or face and feet combination. Don't forget to press the AC button to activate the compressor for cooling—it's also effective for defogging in winter. In summer, open the windows for a few minutes before closing them and turning on the AC to cool down quickly and save fuel. For safety, avoid direct airflow to the face to prevent dizziness, use external circulation on rainy days to reduce fogging, and regularly clean the AC filter to prevent dust buildup and bad odors that affect health.
As a new car owner, I'm a bit unfamiliar with manual air conditioning. After starting the car, I first turn the temperature knob towards the cold air direction. If the car feels hot, I adjust it to the blue end; the fan speed starts from the minimum and gradually increases to check comfort level; the mode knob tries different combinations of blowing on windows or feet. Remember to press the AC switch to activate the cooling, otherwise it's just blowing air. At high speeds, a higher fan speed makes it cooler, while in the city, medium speed saves some fuel. When the AC is on, keeping the windows closed improves efficiency, but occasionally opening the sunroof helps regulate the air inside and outside. At first, forgetting to adjust the mode and blowing directly can feel too cold and uncomfortable, but after a few tries, it becomes very handy. Don't forget in winter to use the warm air direction and AC defogging together to avoid blurred windows affecting visibility.
