What does the Honda rear button mean?
2 Answers
The rear button on a Honda vehicle refers to the rear windshield defogger switch. Pressing this button can remove fog from the rear windshield. Typically, the rear defogger will automatically turn off after about ten minutes to protect the heating filaments. The principle behind the rear windshield defogging system involves embedding copper wires into the rear windshield. When there is moisture or fog on the rear windshield, an electric current heats up these copper wires, warming the glass and eliminating the fog. On the rear windshield of a car, you can see thin copper wires, which are the heating filaments. These metal wires are only about 0.02 to 0.04 millimeters thick. Around 400 to 500 tungsten heating filaments are spaced 2-3 millimeters apart and embedded in a thin PVB plastic film, which is then laminated between the glass layers without obstructing visibility.
In my Honda car, the REAR button controls the rear window defogging function. When I first bought the car, I tried pressing it on a foggy winter morning, and the rear window quickly cleared up, which felt quite convenient. It's not for controlling the rear seats or trunk; it's mainly for defrosting and defogging the rear glass because it has hidden heating wires that warm up when electrified. I recommend using it on rainy or snowy days or during cold starts, but don't leave it on continuously, as it may waste battery or increase fuel consumption. While driving, pay attention to the rearview mirror visibility, and just press it lightly when needed. Maintenance is simple—just remember to check the car's electrical circuits regularly to avoid button malfunctions affecting safety. Personally, I feel this small feature significantly enhances the driving experience.
