Where is the rearview mirror heating button on the Teana?
2 Answers
The rearview mirror heating button on the Teana is the same as the rear window defogging button, located on the air conditioning panel, and can be activated simultaneously. 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 the driver to frequently wipe the mirror manually, 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 needed, as there is an adjustment button on the driver's side. 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 a few minutes, typically between 35-60 degrees. Heat is then emitted from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporates, water droplets on the mirror surface become smaller, and fog gradually dissipates, effectively clearing frost and condensation. 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, which consume a significant amount of power. Ensure the car 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 slightly to allow air circulation between the inside and outside of the car, reducing the temperature difference and gradually clearing fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.
I've been driving a Nissan Teana for over three years, and knowing the location of the rearview mirror heating button is quite important. It's usually located on the air conditioning control panel, where there's a small rear window defrost button—pressing it activates the heating function. On rainy or snowy days, I always press it in advance, and within minutes, the water droplets or frost on the mirror surface disappear, restoring clear visibility. The button is designed in a shared mode and isn’t often marked with a separate icon, so when looking for it, glance toward the lower part of the control panel. Beginners might get confused, but they’ll remember after trying it once. Be careful not to press it forcefully before starting the engine, as it could blow a fuse and cause trouble. Regular maintenance ensures safe driving.
