What is the symbol for auto start-stop?
2 Answers
Auto start-stop button symbol is: an unclosed circle with a small arrow on it and the letter A inside the circle. Information about engine auto start-stop is as follows: 1. Auto shutdown: Automatically shuts off when the vehicle comes to a temporary stop during driving (e.g., waiting at a red light). 2. Auto restart: When it's time to move forward, the system automatically restarts the engine. Extended information: 1. How the start-stop system works: When the vehicle stops due to traffic or at an intersection, the driver presses the brake pedal and shifts to neutral. After these three conditions are met, the engine automatically stops. 2. The start-stop system is called "Start-Stop System" in English; When the vehicle is in a stopped state (not in park), the engine will pause operation (instead of traditional idle speed maintenance). During this pause, the lubricating oil inside the engine continues to circulate, maintaining internal lubrication.
In my years of vehicle maintenance experience, the auto start-stop indicator is typically an intuitive icon on the dashboard or center console. The most common is a button or indicator light with the letter 'A' inside a circle, which lights up green when the system is active and shuts off the engine when parked to save fuel. Identifying its location is straightforward: in most cars, it can be found near the steering wheel within the instrument cluster, such as in Volkswagen or Toyota models where it's easily visible. If the icon doesn't appear, it may be due to the function being turned off or low battery power. I'd like to add that this design has been used in energy-efficient vehicles since the 1980s and has now become standard; it helps reduce urban driving fuel consumption by 5%, but frequent starts may accelerate engine wear, so beginners are advised to read the manual for details. In fact, the indicator color sometimes uses a blue hue to emphasize the energy-saving concept, and different brands like Mercedes may use variant symbols—familiarizing yourself with it can help avoid accidents on slippery roads.
