What is the button with a circle and 'off'?

[MartinAnn]

a circle with 'off' is the auto start-stop function switch. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Additional information: 1. Auto Start-Stop: The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. 2. Auto Hold: Auto Hold refers to an automatic braking function. After activating this function, for example when stopping at a red light, it's equivalent to not needing to pull the handbrake, which can avoid using the handbrake or electronic parking brake and simplify operations. For automatic transmission models, it also eliminates the need for frequent switching between D to N or D to P.
