What is the operation of windshield heat when outside air temperature is 30 degrees or above on the ground?

When the outside air temperature is 30 degrees or above, the operation of windshield heat is designed to optimize performance and efficiency. At this temperature, the need for windshield heat diminishes significantly because the air is warm enough that the likelihood of ice or snow forming on the windshield is low. Consequently, it is beneficial for the system to turn off the windshield heat to conserve energy and reduce unnecessary wear on the heating elements. The system is programmed to operate under these conditions, allowing for better energy management and enhancing overall operational effectiveness, thus making turning off the windshield heat the appropriate response in this scenario.
