Where is the rearview mirror heating button located on the Avalon?

The rearview mirror heating button on the Avalon is located on the center console buttons. Its icon features three upward-curving arrows within a square frame. Pressing this button activates the heating function. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain droplets or fog, eliminating the need for drivers to manually wipe the mirrors frequently 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 adjustment buttons. 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. Heat is then emitted from both left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defogging and deicing the mirror. However, if the rainfall is particularly heavy, the effect 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 significant power. When using this function, ensure the vehicle is running. Avoid activating rearview mirror heating while the car is stationary to prevent draining the battery, which could leave insufficient power to start the vehicle. Other methods for defogging rearview mirrors include: Opening windows for air convection: Crack open both side windows slightly to allow air exchange between the interior and exterior, reducing temperature differences 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.
I've been driving the Avalon for several years, and the rearview mirror heating button is usually located on the driver's side door panel, specifically near or slightly above the window control buttons, marked with a small icon resembling waves or water droplets. If you can't find it there, it might be on the air conditioning panel alongside the rear window defogger button, requiring a press to activate. I find this feature incredibly useful, especially during rainy or foggy weather, as it quickly clears water droplets and frost from the mirror surface, ensuring clearer rear visibility and safer driving. I've used it multiple times myself—just activate it and wait quietly for a few minutes to see the effect. However, the button's location can vary depending on the model year; for instance, newer models might require setting it up in the touchscreen menu. If you really can't locate it, I recommend checking the user manual or asking a technician at the 4S dealership. Don't underestimate this feature—it's particularly crucial for nighttime driving.
