What does the car circle a mean?

Car circle a is the engine start-stop system. Pressing the circle a button, when the moving vehicle is braked to a stop, even if the brake is released, the vehicle will not continue to move. Stepping on the accelerator will automatically make the vehicle move. The functions of the start-stop system are: 1. When encountering a red light or other reasons to stop while driving, the engine will automatically shut off after stepping on the brake for two seconds; 2. When ready to start again, simply release the brake, step on the accelerator, or turn the steering wheel, and the engine will restart. The working principle of the automatic start-stop is: when the system recognizes that the gear is in neutral, the handbrake is pulled, and the clutch is released, it will automatically shut off the engine. When the clutch is pressed again, the engine will automatically start.
When driving, I often notice a light on the dashboard with a circle and an 'A' inside. After researching, I found out that this symbol actually indicates the Traction Control System (TCS) is turned off. Most modern vehicles come equipped with an Electronic Stability Program, of which TCS is a part. It primarily prevents wheel spin by controlling engine power output. However, in certain conditions—like when stuck in snow and needing to dig out, or when off-roading to test the vehicle's limits—manually turning off TCS can be helpful. But it's generally best to keep it on, as the system automatically prevents skidding on slippery roads. If you haven't touched the TCS off button on the center console but this light is on, there might be a fault in the system. Safety comes first, so if the light stays on, it's best to have a professional technician check the fault codes.
