What does an A in a car circle mean?

[VonAngelina]

The A in a car circle refers to the engine start-stop technology, and that A button is called the auto-hold system. After turning on this switch, when your vehicle comes to a complete stop during driving, even if you release the brake pedal, the vehicle will not move forward. It will only resume driving when you press the accelerator, at which point the system automatically cancels the hold function. To deactivate it, you must manually turn it off. Below is an introduction to engine start-stop technology: 1. Technical Introduction: Engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. 2. Working Principle: When the vehicle stops due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks three conditions: the engine is idling and in neutral, the wheel speed sensors of the anti-lock system show zero rotation, and the electronic battery sensor indicates sufficient energy for the next start. If all three conditions are met, the engine automatically stops running.
