Where is the rearview mirror heating switch on the Envision?
1 Answers
The rearview mirror heating switch on the Envision is located on the center console buttons. The "REAR" button, which features a rectangle with three wavy lines, serves as the heating switch for both the rearview mirrors and the rear windshield. 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 rain 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 needed, 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 (typically between 35-60°C) within minutes, distributing heat to both left and right mirrors. As the temperature rises, water droplets on the mirror surface evaporate, and fog gradually dissipates, effectively defrosting the mirrors. However, in heavy rain, the effect may be less noticeable. Precautions for using the rearview mirror heating function: The heating function relies on electric heating wires embedded in the rearview mirrors, which consume significant power. Ensure the vehicle is running when using this feature to avoid draining the battery, which could prevent the car from starting. Other methods for defogging rearview mirrors include: Window ventilation: Slightly opening both side windows creates air convection between the interior and exterior, reducing temperature differences and gradually eliminating fog. Using the car's air conditioning: Adjusting the air conditioning to blow warm air can also help defog the mirrors.
