What does rear mean inside the car?
2 Answers
Inside the car, rear refers to the rear windshield defogging function. Pressing the rear button removes fog from the rear windshield. The rear windshield defogging function mainly works on the principle of heating with resistance wires. Typically, the rear defogger switch turns off automatically after about ten minutes. The rear windshield has heating wires, which are visible as thin copper lines. Pressing the rear button activates these heating wires to defog the rear windshield. The rear defogger switch usually turns off automatically after about ten minutes to protect the heating wires. If the defogging effect is unsatisfactory after activating the rear defogger, it might be due to aging from prolonged use.
I noticed many new drivers are confused by the English abbreviations in cars. "Rear" in a car generally refers to things at the back, most commonly the rear window defogger button—the one with a square icon and the letters REAR. Pressing it activates the heating wires embedded in the rear window glass, evaporating the condensation. Last time, my colleague forgot to turn it on, and the rearview mirror was completely fogged up, which was very dangerous. Some cars place this button on the left panel of the steering wheel, making it easy to press in winter when fogging occurs—just three minutes and you can see the road behind clearly again.
