What does the off button in the car mean?

[AdelynLee]

Car's off button represents turning off. If there is an off under a circle, it is the auto start-stop function's off button. If there is a small car on a button with two curves behind the car and off written under the curves, it is the ESP electronic body stability system's off button. The auto start-stop function is a system that automatically turns off the engine when the vehicle temporarily stops during driving and automatically restarts the engine when it needs to move forward. The electronic body stability system is a general term for systems or programs designed to improve the vehicle's handling performance while effectively preventing the car from losing control when it reaches its dynamic limit. The electronic stability program can improve the vehicle's safety and handling.
