Where is the Lexus rearview mirror heating button located?
1 Answers
The Lexus rearview mirror heating button is located on the center console panel, below the hazard light button. The rearview mirror heating switch for the Lexus NX is a three-position rotary knob, corresponding to the left rearview mirror, rearview mirror heating, and right rearview mirror. Turning the Lexus NX's rearview mirror option to the heating position sets it to "auto mode," activating the car's automatic heated rearview mirror function. Rearview mirror heating is particularly useful in rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for the driver to frequently wipe the mirrors 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 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 (usually between 35-60°C) within minutes. The heat is then distributed across the left and right rearview mirrors. As the temperature rises and evaporates, water droplets on the mirror surface shrink, and fog gradually disappears, effectively defrosting and dehumidifying the mirrors. However, in heavy rain, its effectiveness may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The heating function relies on electric heating wires embedded in the mirrors, which consume significant power. Ensure the car is running when using this feature 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 convection 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.
