How to operate the defogging function on Changan CS75?

First press the A/C switch button, then activate the front windshield defogging button, set the temperature to the lowest level, and adjust the airflow to eliminate fogging. When the car is just started, do not turn on the air conditioner immediately. After the water temperature rises, begin heating, set the airflow to maximum, and turn on the defogging button to make the fog disappear.

As a long-term owner of the Changan CS75, operating the defogging function is actually quite straightforward. After getting in the car, start the engine first so the system can function. Then locate the defogging button on the dashboard—the icon usually resembles a combination of a small fan and the front windshield. Press it gently, and the indicator light will turn on, signaling activation. At this point, the air conditioning will automatically turn on the fan at high speed to help quickly remove moisture and fog, requiring no manual adjustment. If the fog hasn’t cleared, try setting the AC temperature around 22-24°C for a balanced cooling/heating effect. Turning on the external circulation mode is also important, as it draws in dry outside air to clear interior fog faster. In humid winter weather, I usually wait half a minute before driving off—safety first. Regularly cleaning the inner side of the windshield to remove grease buildup can reduce fog formation, ensuring smoother driving. The whole process just requires pressing a button—the CS75’s design is very user-friendly.

From an automotive technical perspective, let's discuss the defogging operation. The defogging mechanism of the Changan CS75 is based on the working principle of the air conditioning system. After starting the vehicle, pressing the dedicated defogging button simultaneously activates the fan, air conditioning compressor, and air distribution system. The button is located near the central console with clear markings for easy identification. When pressed, the system prioritizes directing airflow to the windshield area while adjusting the temperature to the optimal dehumidification state - typically recommended above 20°C to avoid excessive cooling. This process utilizes the principle of air cooling and dehumidification to remove condensation on the glass surface. If the CS75 is equipped with automatic air conditioning, pressing the AUTO button can also intelligently trigger similar functions, but directly pressing the defog button is more precise and convenient. During rainy days or periods of significant temperature variation between morning and evening, this one-button operation ensures clear visibility and enhances driving reliability. I often activate it in advance to avoid distractions while driving. The design also considers energy efficiency balance, with fan noise kept at reasonable levels.

Defogging is crucial for driving safety and should never be overlooked. Whenever I get in the car and find the windshield fogged up, I immediately start the vehicle and press the defog button. The system activates with a single touch, and the illuminated indicator shows it's in operation. During the process, I adjust the air conditioning to a slightly warmer temperature to help evaporate the fog, and I turn on the external circulation mode to speed up airflow. The key is to patiently wait for a few dozen seconds until the fog is completely cleared before driving off, as blurred vision can easily lead to accidents. In the CS75, this function is designed to be highly efficient, handling most situations with just one press. Making it a habit to check before every trip can prevent sudden dangers. Keeping the inside of the windows clean also reduces the chances of fogging. Safety comes first, and cultivating this good habit is worth promoting.

As a novice driver, I also had to figure out the defogging operation when I first drove the Changan CS75. After starting the engine, the first step is to locate the defogging button on the control panel—it has an icon resembling a fan and a windshield. Press it, and the indicator light will turn on. Then, pay attention to the air conditioning settings: adjust the temperature knob to around 22 degrees for a comfortable level, neither too hot nor too cold; the airflow will automatically direct toward the front windshield. While waiting for the fog to clear, don’t rush to drive. If the effect is slow, you can slightly open the window to help with ventilation. The whole process only requires pressing the button once—the CS75’s system is smart enough to handle the remaining steps automatically. With a bit more practice, you’ll get the hang of it. New drivers don’t need to worry; it makes driving safer and more efficient.

Considering seasonal factors, there is a higher demand for defogging in autumn and winter. When operating the defogging function on the Changan CS75, I usually press the defog button immediately after getting in the car to quickly activate the system. The button is typically located in a prominent position in the air conditioning control area—a simple press activates the fan at high speed for dehumidification. Combining this with a temperature setting between 20-25°C and using the external circulation mode yields the best results. If the CS75 is equipped with automatic air conditioning, pressing the AUTO button may sometimes trigger a similar response, but the dedicated button is more direct. In cold weather, warming up the car for a few minutes before operating the system enhances efficiency, helping to clear fog quickly. Keeping the windows clean and dry can reduce the frequency of fogging; I often wipe them to prevent oil film buildup. This design is particularly useful on rainy or snowy days, solving visibility issues with just one press.
