Where is the Mercedes rearview mirror heating switch located?
1 Answers
The Mercedes rearview mirror heating and rear window heating share the same REAR button, located on the center console. When activated, it heats both rearview mirrors simultaneously. The icon features three curved upward arrows paired with a rectangle. Rearview mirror heating 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 electric rearview 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 required, as there is an adjustment button on the driver's side. 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, distributing heat to both left and right mirrors. Meanwhile, as the temperature rises, water droplets on the mirror surface gradually shrink, and fog slowly dissipates, effectively removing frost. However, in heavy rain, the effect may diminish and become less noticeable. The principle of rearview mirror heating involves electric heating wires embedded in the mirror, which consume significant power. When using this function, ensure the car is running. Avoid activating it while the vehicle is stationary to prevent draining the battery and potentially causing starting issues. Alternative methods for defogging rearview mirrors include: Opening windows slightly to create air convection between the interior and exterior, reducing temperature differences and gradually eliminating fog. Adjusting the car's air conditioning to blow warm air, which can also help remove fog.
