Does Tesla Have Heated Rearview Mirrors?
1 Answers
Tesla is equipped with heated rearview mirrors, which are integrated with the rear windshield defroster under a single button. The button features an icon of three upward-curving arrows paired with a rectangular shape. Pressing this button activates the heating function. Heated rearview mirrors are 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. How to use the heated rearview mirror function: The heated rearview mirror function typically has two activation methods. One is combined with the electric rearview mirror adjustment knob—simply rotate the knob to activate it. The other is located on the air conditioning control panel—press the heating button to turn it on. No manual angle adjustment is required, as the driver's side has a dedicated control button. Principle of the heated rearview mirror 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, distributing heat across both left and right mirrors. Meanwhile, due to the temperature rise and evaporation, water droplets on the mirror surface shrink, and fog gradually dissipates, effectively clearing frost and condensation. In heavy rain, the effect may diminish and become less noticeable. Precautions for using the heated rearview mirror function: The heating principle involves electric heating wires embedded in the mirrors, which consume significant power. Ensure the car is running when using this function to avoid draining the battery in a stationary state, which could prevent engine startup. Other methods for defogging rearview mirrors include: Window ventilation: Crack open both side windows slightly to create airflow between the interior and exterior, reducing temperature differences and allowing fog to dissipate slowly. Adjusting the car's air conditioning to the appropriate setting can also direct warm air toward the mirrors for defogging.
