Which button is the rearview mirror heating switch on the 2021 Teana?
1 Answers
The rearview mirror heating switch on the 2021 Teana is the same button as the rear window heating. On the air conditioning panel, there is a square button with an upward arrow, which serves as the switch. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog, eliminating the need for the driver to manually wipe the mirror frequently and thus 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 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 dissipates from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly disappears, effectively defogging and deicing the mirror. 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 adding electric heating wires to the mirror. These wires consume a significant amount of power. When using this function, ensure the car is in an active state (engine running). Avoid activating the rearview mirror heating while the car is stationary to prevent draining the battery, which could lead to insufficient power for starting the car. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Crack open both 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, as blowing warm air from the AC can effectively remove fog.
