The button's icon is a rectangle with three upward-curving lines with arrows from the bottom to the top. How the Rearview Mirror Heating Works: The principle of rearview mirror heating is quite simple. It involves embedding an electric heating film behind the mirror, utilizing the resistance heating principle to achieve temperatures between 35-60°C. This feature is particularly noticeable in winter or foggy conditions, while its effect is less obvious at normal temperatures. Generally, rearview mirror heating does not turn off automatically, so remember to switch it off after use to avoid draining the battery. Although the heating power is not high, prolonged use is not recommended to prevent damage to the heating element. Function of Rearview Mirror Heating: With the rearview mirror heating function, frost or ice on the mirror surface quickly disappears, ensuring that drivers' visibility remains unaffected even in harsh weather conditions, making it highly convenient. Additionally, the rearview mirror heating button and the rear window defogger switch in this vehicle model are interconnected. This means that activating the rearview mirror heating system also turns on the rear window defogging system, allowing both to operate simultaneously.
