Where is the rearview mirror heating switch on the Envision?

[SanAdrian]

The rearview mirror heating button on the Envision is located in the air conditioning control area of the center console. The button is positioned above the AC button and features an icon of a rectangle with three wavy lines. Note that the Envision's rearview mirror heating button is the same as the rear window defogging/heating button. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for frequent manual wiping by the driver and thereby reducing driving hazards. The rearview mirror heating function can generally be activated in two ways: one is combined with the power-adjustable rearview mirror control 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 required, as there is a control button on the driver's side. When the button is pressed, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature (usually between 35-60°C) within minutes, distributing heat to both left and right mirrors. Simultaneously, due to the rising temperature and evaporation, water droplets on the mirror surface will shrink, and fog will gradually disappear, effectively defogging and deicing the mirror. However, in heavy rain, the effect may diminish and become less noticeable. The principle of rearview mirror heating involves the addition of electric heating wires to the mirrors. These wires consume a significant amount of power. Therefore, when using the rearview mirror heating function, ensure the vehicle is running. Avoid activating this function while the car is stationary to prevent draining the battery, which could lead to insufficient power for starting the vehicle. Other methods for defogging rearview mirrors include: 1. Opening windows slightly to create airflow between the inside and outside of the car, reducing the temperature difference and allowing fog to dissipate gradually. 2. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.
