Where is the rearview mirror heating switch on the Buick Verano?
1 Answers
The rearview mirror heating switch on the Buick Verano is located directly above the air conditioning fan speed knob, labeled "REAR." Turning on this switch activates heating for both the side mirrors and the rear window. A yellow light indicates that the heating function is on, and the light turns off when heating is deactivated. The heating function will automatically turn off after a period of use. Rearview mirror heating is particularly useful in rainy or snowy weather, as the heater behind the mirror quickly warms the surface, gradually removing rain or fog without the need for manual wiping, 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 mirror adjustment knob—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. How rearview mirror heating works: After rotating the knob, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature (usually between 35-60°C) within minutes, distributing heat across both side mirrors. As the temperature rises, water droplets and fog on the mirror surface gradually evaporate, clearing the glass. However, in heavy rain, the effect may be less noticeable. Precautions when using the rearview mirror heating function: Rearview mirror heating relies on electric heating wires embedded in the mirrors, which consume significant power. Ensure the vehicle is running when using this feature to avoid draining the battery, which could prevent the car from starting. Other methods to defog rearview mirrors include: Opening windows slightly to allow air circulation, reducing the temperature difference between inside and outside the car, which helps eliminate fog. Adjusting the car's air conditioning to blow warm air onto the mirrors for defogging.
