How to turn on the air conditioning cold air in Audi A4L?

Press the middle fan speed button (the '-' button) on the air conditioning panel. Keep pressing until the fan speed reaches 'O', and the air conditioning system will turn off. Press the ECON button on the air conditioning panel to light up the button's indicator. This will turn off the air conditioning cold air system, allowing only natural air or warm air to be used. Rotate the fan speed switch to the minimum position. When the system turns off and the ECON light is on, the air conditioning cold air system will be turned off.
After starting the car, I usually press the AC button with the snowflake icon on the center console to activate the compressor, then turn the left temperature knob toward the blue direction to lower the temperature. At this point, the air conditioning will automatically start cooling, and the fan speed will adjust automatically based on the cabin temperature. If it doesn't feel cool enough, you can manually increase the fan speed or press the medium fan speed increase button. If the car is particularly hot when first getting in, I prefer to open the windows for ventilation for a few dozen seconds before closing them and turning on the AC, as this cools the car down faster. Remember to press the recirculation button to prevent hot outside air from entering, which improves cooling efficiency. Once the temperature drops, you can switch to fresh air mode to maintain air circulation. Audi's automatic climate control system is quite intelligent—once you set the temperature, you don't need to worry about it anymore.
