How to use the air conditioning in an old Audi A6: 1. There are red and blue color marks on both sides of the air conditioning adjustment switch. The red area gradually increases the temperature, and the blue area gradually decreases the temperature. Simply turn the knob; 2. For automatic air conditioning, set a temperature and press the AUTO button, and the automatic air conditioning will adjust automatically according to the temperature inside the car. The functions of the air conditioning are: 1. To cool, heat, ventilate, and purify the air inside the car; 2. To provide a comfortable environment for passengers, reduce driver fatigue, and improve driving safety. Maintenance methods for the air conditioning: 1. Clean the air conditioning vents in time; 2. Maintain the air conditioning condenser in time; 3. Clean or replace the air conditioning filter element in time.

After starting the engine, I usually press the air conditioning button, which typically has a small snowflake symbol. When it lights up, the cooling function is activated. Then, I adjust the temperature knob - the blue side on the left represents cooler air, while the red side on the right provides heating. Setting it to the right position makes things much more comfortable. Don't forget to adjust the fan speed; there's a rotary knob that controls the airflow intensity, ranging from gentle to powerful. The air vent position knob is crucial - choose to blow air on the windshield to defog it and prevent misting, or direct it at your face for cooling and to avoid stuffiness. Older car air conditioning systems are prone to aging, so I recommend regularly replacing the filter to prevent odors. It's normal for the heating to take longer to warm up in winter, so no need to worry. Checking the pipes before long trips to prevent leaks provides peace of mind.

After turning the key to start the engine, I always press the AC button first to activate the air conditioning. The humming sound gives me peace of mind. Turn the left knob to adjust the temperature, setting the target temperature without fluctuation. Use the fan switch to control the speed—lower in summer to avoid excessive cooling and higher in winter for quicker warmth. Don’t overlook the mode dial; choose foot-level airflow for warmth or windshield airflow for defogging—it’s highly practical. My old Audi’s AC occasionally malfunctions; when the vents get dirty, I spray cleaner to maintain it, extending its lifespan effortlessly. For daily use, cracking the windows slightly improves air circulation inside the car.

After ignition, press the AC switch to activate the system, and use the temperature control knob to set your comfort level. Adjust the fan speed lever to prevent excessive airflow. For older Audi models, select front/rear or mixed air distribution modes for easy operation. Remember to regularly clean the filters to maintain efficiency.
