What does Aoff on a car mean?

[DiCali]

On a car, Aoff refers to the button that turns off the auto start-stop function. The auto start-stop function can reduce exhaust emissions and save fuel. When the auto start-stop function is enabled, simply pressing the brake pedal while driving will cause the engine to automatically shut off after the vehicle comes to a complete stop for a few seconds. Releasing the brake or turning the steering wheel will automatically restart the engine. Additional information is as follows: 1. Function of Aoff: When the Aoff light is on, it indicates that the vehicle's engine auto start-stop function is active. This feature effectively protects the engine from damage and reduces fuel consumption, making it very practical. 2. When to turn off Aoff: Normally, the Aoff function can remain on, but it needs to be turned off when the vehicle is driving through deep water to prevent engine damage. As for how deep the water must be to require turning off Aoff, use the car's tires as a reference. If the water depth exceeds half the diameter of the car's tires, the Aoff function must be turned off; otherwise, the engine may be damaged.
