What is the purpose of the button on the automatic transmission lever?

[JulietFitz]

The button on the automatic transmission lever is called the shift lock. It is a mechanism designed to prevent accidental operation, differing from the serpentine transmission design commonly found in Japanese and Korean models. Below is an introduction to the automatic transmission shift lock button: 1. When shifting from P to R, the button must be pressed to engage the gear. Similarly, R to P requires pressing the button, while R to N does not. N to R requires pressing the button, but N to D does not. D to N does not require pressing, while D to S does. S to D does not require pressing, and D to +/- can be directly engaged. 2. As the name suggests, an automatic transmission does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on driving speed and traffic conditions.
