What turns on the heated side mirrors on Kia Sportage?

In the Kia Sportage, the heated side mirrors are activated when you turn on the rear defroster. This feature is designed to help clear ice, snow, and fog from the mirrors, improving visibility in adverse weather conditions. The rear defroster button is typically located on the center console or dashboard. Once activated, the heated mirrors will operate as long as the defroster is on.
