What is the function of the car aoff button?

[Maria]

The function of the car aoff button is auto start-stop. Meaning of auto start-stop: Engine auto start-stop 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. This is achieved by equipping traditional engines with an enhanced motor featuring idle start-stop capability, allowing the engine to completely shut off when idle stop conditions are met. Advantages of auto start-stop: It can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. In urban traffic when waiting at traffic lights or during traffic jams, it minimizes engine idling time. Moreover, after the engine shuts off, the power supply can replace the belt pulley to provide operating power for the engine cooling fan and in-car air conditioning.
