[AdrianaLee]

raar button means rear window defogging. The following is an introduction to the relevant content: Meaning: The literal meaning of rear is the back or rear part, and the rear button on the car appears in the car air conditioning, which is actually the rear window defogging button. However, many models now omit the English word rear and directly use an icon. Defogging: The copper wires seen on the rear window of the car are heating wires. By clicking the rear button, the rear window heating wires are activated for defogging. Automatic shutdown: After the rear window defogging switch is turned on, it will automatically shut down after about ten minutes to protect the heating wires.
