What is the function of the REAR button in a car?
1 Answers
The REAR button in a car is for the rear window defogging and defrosting function. Pressing it can remove fog from the rear windshield. Below is some related information about defogging: 1. Open windows for convection: Open a gap in both side windows to allow air convection inside the car. When the interior temperature approaches the outside temperature, the fog will dissipate. 2. Use air conditioning for defogging: Press the A/C button (A/C stands for air conditioning cooling), lower the temperature, turn on the window defogging button, and set the fan speed to maximum. This quickly reduces the temperature of the window glass by evaporating surface moisture, achieving the defogging effect. 3. Use defogging spray: The principle of defogging spray is to apply a layer on the windshield, forming an effective protective film.
