What is the function of the button in front of the gear lever on the Lavida?

[HarperLee]

The button in front of the gear lever on the Lavida is designed for safety purposes. It ensures that the reverse gear or parking gear can only be engaged when this button is pressed. Some vehicles require this button to be pressed for any gear shift, primarily to prevent accidental gear changes caused by unintentional contact with the gear lever during driving. When the gear is in the P (Park) position, it is impossible to shift without pressing this button, effectively eliminating potential safety hazards caused by misoperation. Detailed usage instructions: When shifting from P to R, the button must be pressed to engage the gear; the same applies when shifting from R to P. However, shifting from R to N does not require pressing the button. Shifting from N to R requires pressing the button, while shifting from N to D does not. Shifting from D to N does not require pressing the button, but shifting from D to S does. Shifting from S to D does not require pressing the button, and shifting from D directly does not require pressing the button either.
