3 Answers
Open the central control multimedia screen of BYD, select and enter the air conditioning interface, then click the rear window defogging/rearview mirror heating switch to activate the rearview mirror heating function. Additionally, objects seen in the exterior rearview mirrors appear farther away than their actual distance. After adjusting the driving posture, proceed to adjust the interior and exterior rearview mirrors. Prolonged use of the rearview mirror heating and defrosting function may lead to premature aging of the mirror. Remember to turn off the defrost button when it is not needed.
As an owner of the BYD Tang, turning on the rearview mirror heating is quite simple. You just need to locate the button with a square and wavy lines on the air conditioning control panel—that’s the shared button for rear window defogging and rearview mirror heating. Press it once, and you’re good to go. It’s especially useful on rainy days or when there’s heavy fog. I often use this feature during morning rush hour, and the heating works quickly, clearing fog within minutes for better visibility. Honestly, this feature is thoughtfully designed—it doesn’t take up extra space but integrates with the system, avoiding additional switches and improving daily convenience. I recommend regularly cleaning the rearview mirror surface to prevent dust from affecting heating efficiency and ensure driving safety. In particularly wet or cold weather, start the vehicle first before pressing the button for more stable results.
As a tech enthusiast, I'm quite familiar with the rearview mirror heating operation. On the BYD Tang, this feature is integrated into the rear defogger function of the air conditioning system. Typically located in the button area of the instrument panel or center console, you can identify it by the icon showing a square with several curved lines. Simply press it to activate the heating. The principle behind rearview mirror heating involves rapid temperature rise through resistance wires to remove rain and fog, making it highly efficient. The operation is straightforward and intuitive, requiring no additional settings. During my tests, I found it responds quickly, capable of clearing fog within five minutes. From a safety perspective, it helps reduce the risk of blind spot accidents, and when combined with blind spot monitoring, it provides even greater peace of mind. Remember not to touch the mirror immediately after heating to avoid burns. Regularly check the wiring connections and fuses to prevent potential malfunctions.
