Where is the rearview mirror heating switch on the Hyundai Elantra?

The rearview mirror heating function is located in the air conditioning control area. There is a button with a square frame and three curved lines, which is the rear window defroster button and also serves as the rearview mirror heating button. The rearview mirror heating function 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 the driver to manually wipe the mirror frequently and thus reducing driving hazards. How to use the rearview mirror heating function: The rearview mirror heating function can generally be activated in two ways. 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 dedicated adjustment 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 a few minutes, typically between 35-60 degrees Celsius. The heat is then distributed across the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defrosting and defogging the mirror. However, in heavy rain, its effectiveness may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves electric heating wires embedded in the mirror, which consume a significant amount of power. When using this function, ensure the vehicle is running. Avoid activating the rearview mirror heating while the car is stationary to prevent draining the battery and potentially leaving insufficient power to start the engine. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Slightly lowering both side windows creates airflow between the interior and exterior, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting can also help by blowing warm air to defog the mirrors.
