What is that below the start button of the Mercedes-Benz A200L?

Below the start button of the Mercedes-Benz A200L is the auto start-stop switch. Meaning of auto start-stop: Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a traffic light) during driving. When it's time to move forward again, the system automatically restarts the engine. This is achieved by equipping traditional engines with an enhanced motor that has idle start-stop functionality, allowing the engine to completely shut off when idle stop conditions are met. Advantages of auto start-stop: It can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. In urban traffic, while waiting at traffic lights or during traffic jams, it minimizes engine idling time. Additionally, after the engine shuts off, the electrical system can replace the belt-driven functions to power the engine cooling fan and in-car air conditioning.
I've been driving a Mercedes-Benz A200L for two years, and the round button below the start button is the automatic air conditioning mode button. When it's unbearably hot in the summer, pressing it automatically adjusts the temperature and fan speed, which is much more convenient than manual control. The position is ergonomically designed—your right hand can naturally reach it after pressing the start button. For daily temperature adjustments, just turn the knob next to the central control screen—no need to press AUTO every time. If the airflow feels off, check if you accidentally pressed the recirculation button or if the filter needs replacing. Automatic air conditioning is quite common in luxury cars like Mercedes-Benz and is practically a standard feature.
