What is the symbol for car rearview mirror heating?
1 Answers
The rearview mirror heating symbol is a pattern of three upward-curving arrows combined with a rectangle. The location of the rearview mirror heating switch varies among different car models, but the symbol is generally similar. Car rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for frequent manual wiping by the driver and thereby reducing driving hazards. Methods to use the rearview mirror heating function: There are typically two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is required, as the driver's side has a control button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, usually between 35-60 degrees Celsius. Heat is then emitted from the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface become smaller, and fog gradually disappears, effectively defogging and deicing the mirror. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror, which consume a significant amount of power. When using this function, ensure the car is in an active state. Avoid activating rearview mirror heating while the car is stationary to prevent draining the battery and potentially leaving insufficient power to start the car. Other methods to defog rearview mirrors include: Opening windows for airflow: Crack open the side windows slightly to allow air exchange between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.
