What does the AST button in the car mean?

The AST on the car CD refers to automatic-broadcast-station-storage, which means automatic station memory. Using this button, the radio can automatically search and store stations. Here are other buttons on the car CD and their functions: 1. POWER/VOL (left rotary knob): Press to turn on/off, rotate to adjust volume. 2. TPK/MANU (right rotary knob): MP3 track selection and browsing. 3. RPT: Repeat playback in CD/USB mode.
I remember when I first saw that AUTO button in the car, as a veteran driver with over 20 years of experience, I initially found it mysterious. Later, I learned that it's the switch for the automatic air conditioning mode. Once pressed, the system automatically senses the temperature and humidity inside and outside the vehicle, adjusting the fan speed and air temperature to reach your set target temperature. For example, setting it to 24°C in summer and 20°C in winter will blow cool or warm air to achieve comfort. The fan speed adapts automatically, so no need to worry about it being too noisy; you can also manually intervene, like lowering the speed if the airflow feels too strong. Additionally, the system automatically switches between recirculation and fresh air modes, but if you're stuck in city traffic, I recommend manually switching to recirculation to prevent exhaust fumes from entering the cabin. This button really makes driving more worry-free, especially on long trips, allowing you to focus on the road without distractions from adjusting the AC.
