Where is the rearview mirror heating button on the Buick Verano?

[VonGabrielle]

The rearview mirror heating switch on the Buick Verano is located directly above the air conditioning fan speed knob. This switch is labeled "rear." Turning it on activates heating for both the upper and lower rearview mirrors as well as the rear window. A yellow light indicates that the heating function is active, and the light turns off when the heating is deactivated. The heating function will automatically turn off after a period of use. 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 drivers to manually wipe the mirrors and reducing driving hazards. How to use the rearview mirror heating function: The rearview mirror heating function can typically be activated in two ways: either by rotating a knob combined with the electric mirror adjustment controls or by pressing a dedicated button on the air conditioning control panel. No manual angle adjustment is required, as the driver's side has a dedicated adjustment button. Principle of the rearview mirror heating function: When the button is pressed, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature, usually between 35-60 degrees Celsius, within a few minutes. Heat is then emitted from both left and right rearview mirrors. As the temperature rises, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively defogging and deicing the mirror. However, in heavy rain, the effect may be diminished and less noticeable. Precautions for using the rearview mirror heating function: The rearview mirror heating function works by incorporating electric heating wires into the mirror. These wires consume a significant amount of power. To avoid draining the car battery, ensure the vehicle is running when using this function. Avoid activating rearview mirror heating while the car is stationary to prevent insufficient battery power for starting the engine. 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 eliminating fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.
