What does 'push' mean on a car?

[MacRemington]

The 'push' on a car indicates that the button is operated by pressing. Typically, 'push' appears alongside corresponding function icons or characters, signifying that the function can be activated by pressing. 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. Below are specific applications of 'push' in cars: 1. Airflow direction: The 'PUSH' in the middle of the airflow direction (also called mode) knob (with a defrosting symbol below) lights up when pressed to activate rear window defrosting. 2. Temperature: The 'PUSH' in the middle of the temperature (also called heating/cooling) knob (with an air recirculation symbol below) lights up when pressed to activate air recirculation. 3. Handbrake: On some vehicles, 'push' may appear on the handbrake. The handbrake, technically known as an auxiliary brake, operates differently from the main brake system. It uses a steel cable connected to the rear brake shoes to apply braking force. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation, which is irreversible and can reduce effectiveness over time, also increasing the handbrake's travel distance.
