What does 'push' mean on a car?

[LilahRose]

The 'push' on a car indicates that the button should be pressed. Here is some related information about 'push': 1. Corresponding function: Usually, 'push' appears alongside a relevant function icon or text, indicating that pressing it will activate that function. If a knob has 'push' in the middle, it means the knob can be pressed in the center, and pressing it will activate a certain function. 2. Identification method: For the airflow (also called mode) control knob, pressing the 'push' in the middle will turn on the rear window defroster when the light is on. For the temperature (also called climate) control knob, pressing the 'push' in the middle will turn on the recirculation mode when the light is on.
