Can Hot Air Defog?
1 Answers
Proper use of the car's heating system can achieve a defogging effect. Here are the specific details on how to use the car's heating system: Method to Activate: First, start the engine for preheating. Wait until the engine temperature gauge reaches the middle position, then turn on the heating air conditioning. Set the air circulation to external circulation to expel the cold air inside the car. After 2~3 minutes, switch the air circulation to internal circulation. Precautions for Long-term Use: Avoid directing the warm air straight at the 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 heating system for an extended period. This ensures adequate oxygen levels inside the car, keeping the driver alert.
