The rearview mirror heating switch for the Envision is located on the center console buttons. The "REAR" button, which features an icon of a rectangle with three wavy lines, serves as the heating switch for both the rearview mirrors and the rear windshield. 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. How to use the rearview mirror heating function: There are generally 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 dedicated adjustment button. Principle of the rearview mirror heating function: After rotating the knob, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. The heat is then distributed across the left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface shrink, and fog gradually dissipates, effectively defrosting the mirror. However, in heavy rain, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The heating principle involves electric heating wires embedded in the rearview mirror, which consume significant power. Ensure the vehicle is running when using this function to avoid draining the battery, which could prevent the car from starting. Other methods for defogging rearview mirrors include: Opening windows for air circulation: 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. Using the car's air conditioning: Adjust the air conditioning to the appropriate setting to blow warm air for defogging.
