Where is the rearview mirror heating switch for the 2021 RAV4?
1 Answers
The rearview mirror heating and rear windshield heating for the 2021 RAV4 share the same button. It is located in the middle of the bottom row of the center console, labeled with the word "REAR." Pressing this button activates the heating function. The 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, eliminating the need for frequent manual wiping and reducing driving hazards. Rearview mirror heating function principle: 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. The heat is distributed across the left and right rearview mirrors. Meanwhile, as the temperature rises and evaporation occurs, water droplets on the mirror surface shrink, and fog gradually dissipates, effectively clearing frost and fog. However, if the rain 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. These wires consume a significant amount of power. When using the rearview mirror heating function, ensure the car is running. Avoid activating the heating function while the car is stationary to prevent draining the battery and potentially leaving insufficient power for starting the engine. 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. This reduces the temperature difference, causing the fog to gradually disappear. Adjusting the car's air conditioning to the appropriate setting can also help by blowing warm air to defog the mirrors.
