The rearview mirror heating switch button for the 2020 RAV4 Feng Shang is located on the air conditioning control panel and shares the same button as the rear window defroster. The button features a rectangle with three upward-curving arrows at the bottom. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog without the need for frequent manual wiping, thereby reducing driving hazards. 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, typically between 35-60 degrees Celsius. The heat is distributed across the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface shrink, and fog gradually dissipates, effectively clearing frost and condensation. However, in heavy rain, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The rearview mirror heating function works by incorporating electric heating wires, which consume a significant amount of power. Ensure the vehicle is running when using this feature to avoid draining the car , which could prevent the engine from starting. Avoid activating the rearview mirror heating while the car is stationary. Additional methods for defogging rearview mirrors include: Opening windows slightly to allow air circulation 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.

Speaking of the rearview mirror heating switch on the 2020 RAV4 Rongfang Fashion Edition, it's actually located in the most convenient position while driving - on the air conditioning control panel. I drive the same model and was confused when looking for it the first time too. Look at the row of air conditioning buttons in the center console, find the square icon with curved arrows and the word "REAR" on it. Every time it rains or the mirrors fog up, I just press it and both the rearview mirrors and rear windshield start heating together. After a few minutes, the visibility becomes crystal clear. However, I should remind you that this function only works when the vehicle is started, and it automatically turns off after about 20 minutes to protect the circuits. Compared to models with separate switch designs, this integrated approach is indeed much more convenient.

I often help friends locate small features in their cars. The 2020 RAV4's rearview mirror heating is quite easy to find—there's no dedicated button for it. When you're in the driver's seat, just look down at the central air conditioning panel near the temperature knob. Among the four square buttons there, the one on the far right with a wavy line symbolizing a window is the one. It combines rear window defogging and mirror heating into a single function—a space-saving and practical design. While this feature isn't needed in summer, it's particularly useful during autumn and winter mornings or rainy days when the glass fogs up. The button has a noticeable tactile feedback when pressed and lights up orange. Remember, the air conditioning must be on for this function to work. Many features in cars are designed with such interconnected functionality, and once you get used to them, they feel very intuitive.

Last year when I just got my new car, I specifically studied the manual. The rearview mirror heating switch is located at the lower right corner of the AC control panel, sharing the same button with the defogging function. Simply press to illuminate it after starting the engine - the indicator light shows it's working. Field tests show it takes effect within five minutes. This feature is particularly lifesaving during rainy or snowy weather.

I've been driving the RAV4 Fengshang for almost two years now, and I frequently use the rearview mirror heating function. Its switch is located right next to the air conditioning knob—a rectangular button with an arrow and ripple pattern. On foggy days or when the mirrors frost over in winter, I press this button and wait 3 to 5 minutes for the lenses to gradually clear up. Although the button icon looks like it's for rear window heating, it actually controls both the rear window and the rearview mirrors. One detail I've noticed is that it doesn't activate automatically when I remotely start the vehicle in advance; I have to manually press it after getting in the car. It would be even better if it could be controlled via the app. I recommend remembering to turn it on when driving in the rain to avoid poor visibility when changing lanes.

As car enthusiasts from the northeast, the rearview mirror heating function is absolutely essential for us. The 2020 RAV4 Feng Shang edition is cleverly designed - the first button on the right side of the AC panel with dotted lines and an arrow activates it. During my last self-drive trip to Changbai Mountain in heavy snow, I used this when both front and rear windows froze, and discovered that the rearview mirrors and rear window heat up simultaneously. Just note that if the outside temperature is too low, it works slower, so it's best to activate it 5 minutes in advance. The button has excellent tactile feedback with clear touch response. I really appreciate this integrated design - unlike some cars that have three or four defrost buttons that are confusing to locate.
