What does the rear sign on a car mean?
2 Answers
Car's rear sign means the rear window defrosting and defogging function. The principle of the rear window defogging device is to embed copper wires in the rear window. When there is moisture or fog, it uses electric current to heat some of the copper wires, thereby heating the window to disperse the fog. After pressing the rear button for 10 minutes, the system will automatically shut down to protect the heating wires. Precautions for using car air conditioning: 1. Avoid turning on the air conditioning immediately after getting in the car, as this will not quickly reduce the temperature inside the car but will increase the operating pressure of the car; 2. Avoid using the internal circulation system for a long time, as this will lead to poor air quality inside the car, affecting the respiratory systems of the driver and passengers; 3. Do not leave the air conditioning unused for a long time, as prolonged disuse can breed mold.
When I first learned to drive, I was also confused by the 'rear' label on the dashboard. It actually controls the rear functions of the car. The most common is the 'rear' button on the air conditioning panel, which adjusts the temperature for the rear seats, making passengers more comfortable. On rainy days when the windows fog up, using it to activate the rear defroster is especially effective, quickly heating the defogging lines on the rear window. I've driven several different models, and in SUVs, it can also control the direction of the rear air vents. Don't confuse it with the 'front' label, which controls the front. Make it a habit to observe these labels while driving to avoid mistakes, like preventing rear window fog from obstructing your view on the highway. Remember, the button usually lights up when activated, and turning it off before shutting down saves power. Regular maintenance, like checking the wiring for good contact, is simple but important.
