The A-circle button in a car represents the auto start-stop function. Here are the specific details about auto start-stop: How to use the auto start-stop function in a car: 1. For automatic cars: When parking, press the brake for 1 to 2 seconds, and this function will automatically stop the engine. Simply lightly press the accelerator or turn the steering wheel to restart the engine. 2. For manual cars: The computer determines the start-stop function based on actions such as pressing the clutch, shifting to neutral, and pulling the handbrake. 3. Situations to turn off start-stop: You can choose to disable this function when slowly moving forward in congested traffic, reversing into a parking space, or driving on steep slopes.
I've been driving for over a decade, and this 'A' circle button represents the auto start-stop function. It means the engine automatically shuts off when you stop at a red light to save fuel, and restarts when you press the accelerator. I often use it in city driving, which can reduce fuel consumption by about 5% and lower emissions, which is great. But after prolonged use, I've noticed issues: frequent start-stop in traffic jams causes noticeable vibrations, affecting driving comfort, especially when the air conditioning cuts off during summer, which is annoying. I recommend beginners start using it in simple road conditions and learn to toggle it flexibly once accustomed. If the battery ages quickly or the starter wears out, turn it off promptly to ensure safety. Overall, the design aims to be eco-friendly and energy-saving, but don't neglect maintenance to avoid increased repair hassles.
