Where is the rearview mirror heating button on the Envision?

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.

I've been driving my Envision for over three years, and the rearview mirror heating button is actually very easy to find—it's integrated into the air conditioning control panel and shares the same button as the rear window defroster. For most model years, the design places it on the center console, near the knob or below the screen, where you'll see an icon resembling a square with wavy lines inside. Just press it. When the weather is humid or foggy, pressing it activates the system automatically for a few minutes, quickly heating the mirrors to clear fog—super practical. Personally, I recommend turning it on right after starting the car in winter to preheat the mirrors and avoid poor visibility of side and rear traffic. Remember to check if the air conditioning settings are on; a small light will illuminate when the function is active, ensuring everything works properly. This design is smart, combining frequently used features to save space and make operation easier.

To locate the rearview mirror heating button in the Envision, simply look for the rear window heating button on the right side of the center console—usually the same button with a windshield-like icon. Operation is straightforward: press it to simultaneously activate both front and rear heating elements, quickly melting frost or fog on the mirrors in winter. I often use it before driving in rain or snow, significantly improving visibility and safety without extra tools. The Envision’s integrated system eliminates multiple buttons—just check the indicator light to confirm activation. Keep the panel clean to prevent button jams; this streamlined design aligns well with modern automotive trends.

As an experienced driver using the Envision, the rearview mirror heating button is located in the air conditioning control area, sharing a key with the rear window heating function, making it easy to identify. Look for the small icon resembling thermal lines on the panel – just press it lightly. During wet and cold weather, the feature automatically operates to remove fog, preventing safety hazards. I usually activate it for a few minutes before driving in the early morning or evening, which significantly improves mirror clarity and helps avoid blind spot accidents. Familiarizing yourself with the button position makes life easier, especially for elderly drivers who won't need to bend over or struggle with operation.
