What does rear mean in a car?

[Ray]

The rear button on a car typically appears in the air conditioning system and serves as the rear windshield defogger button. Nowadays, many car models omit the English word "rear" and simply use an icon instead. Below are some relevant details: 1. On the rear windshield of a car, you will notice thin copper wires, which are heating elements. Pressing the rear button activates these heating wires to defog the rear windshield. 2. Usually, the rear windshield defogger switch automatically turns off after about ten minutes to protect the heating elements. 3. Most cars currently on the market are equipped with a rear windshield heating function. While the button location may vary, the functionality remains the same. After turning on the rear windshield heating switch, the fog on the rear windshield typically disappears within about a minute.
