What is the main function of the vehicle's rear window defogger system?

Question

DentroTest · Accepted Answer

The correct answer is to eliminate ice and mist. The rear window defogger (or heated rear window) is an active safety feature designed to ensure driver visibility through the interior rear-view mirror. It works via conductive filaments embedded in the glass that, when activated, heat up using electricity to evaporate condensation (mist) or melt ice and frost caused by adverse weather conditions. Explanation of incorrect options: It is not for heating passengers: The heat emitted is localized specifically to the glass surface and lacks the power to control the cabin temperature. It does not prevent breakage: The filaments are electrical components and do not serve a structural reinforcement function for the glass.
