What does AST mean in a car?
2 Answers
AST in a car stands for Automatic Station Memory, which means the radio can automatically search and store stations using this button. When using autoscan, it automatically memorizes the frequencies of stations with signals, allowing you to select stations by pressing the button later. Holding this button down automatically stores radio stations. The radio is a voice entertainment feature in cars and one of the common configurations in the vehicle's audio-visual entertainment system. Other buttons and functions of the car CD player: 1. POWER, VOL: Press to turn on/off, rotate to adjust volume; 2. TPK, MANU: MP3 track selection and browsing; 3. RPT: Repeat playback in CD/USB mode; 4. INT: Browse playback in CD/USB mode; 5. RDM: Random playback in CD/USB mode; 6. AUXINUSB: USB player interface, standard 3.5mm audio interface; 7. MEMU: Enter MP3 folder selection mode in CD/USB mode.
In our veteran driver circles, the term 'ast' commonly refers to the auto start-stop function. This feature automatically shuts off the engine when waiting at traffic lights or in traffic jams, and restarts it when the brake is released. Although it can save some fuel costs, after driving for Didi for seven or eight years, I feel it causes significant wear to the engine and battery. Especially when the air conditioning is on in summer—the compressor stops and has to restart cooling, which can actually consume more fuel. I recommend turning it off directly if stuck in traffic for more than two minutes. Newer cars have a button with an 'A' on the steering wheel to control this function.
