Can the Heater Defog Windows?
1 Answers
Proper use of the car heater can effectively defog windows. Here are specific instructions for using the car heater: 1. How to turn it on: First, start the engine for preheating. Wait until the engine temperature needle reaches the middle position, then turn on the heater air conditioning. Set the air circulation to external circulation to expel cold air from the car. After 2-3 minutes, switch the air circulation to internal circulation. 2. Precautions for prolonged use: Avoid directing the heater airflow straight at your head, as prolonged exposure can cause driver fatigue and affect driving safety. Therefore, it is recommended to slightly open the window for air circulation when using the heater for extended periods, ensuring sufficient oxygen levels inside the car to keep the driver alert.
