Is the aoff button a start button or a shutdown button?

[DiSilas]

aoff is the shutdown button for the auto start-stop function in cars. The auto start-stop function can reduce exhaust emissions and save fuel, and many cars are now equipped with it. Here are the details: 1. Cars equipped with the auto start-stop function have a shutdown button, and pressing the button can turn off the auto start-stop. The shutdown button for auto start-stop is not actually aoff, but a circle with an A inside and off below the circle, which represents turning off the auto start-stop. 2. For cars with the auto start-stop function, when waiting at a red light, as long as the battery has sufficient charge and the engine water temperature reaches the normal temperature, the system will shut down the engine. If the battery charge is insufficient, the auto start-stop system will not work.
