How to Defog a New Santana on Rainy Days?
3 Answers
Open a small gap in both side windows to create airflow between the inside and outside of the car, reducing the temperature difference and allowing the fog to gradually dissipate. Using the air conditioning system to defog is the most common method. Simply adjust the air conditioning to the appropriate setting to utilize the airflow from the vents to clear the fog.
I've driven the new Santana a few times, and foggy windows on rainy days are a common issue. Once during heavy rain, I simply pressed the defog button on the center console—the one with the fan symbol—and it immediately switched the AC to dehumidification mode. I usually set the temperature around 22°C and adjust the airflow to blow onto the windshield, as warm air quickly evaporates moisture on the glass. Turning on the external air circulation is also crucial, as it balances humidity inside and outside the car, preventing fog buildup. Don’t forget to clean the interior of the windows with a damp cloth to remove grime; reducing oily residue helps disperse fog faster. For safety, stay calm if fog forms—cracking the window slightly for ventilation while using the wipers can significantly improve visibility. For long-term prevention, I regularly maintain the AC system to ensure the evaporator functions properly, avoiding future hassles. These simple and practical methods work like a charm—give them a try.
Driving in heavy fog during rainy days is very dangerous, as blurred vision can easily lead to accidents. I believe that operating the defogging function in the new Santana should prioritize safety: after starting the engine, immediately turn on the air conditioning system and select the dehumidification function or defrost mode. Then, adjust the airflow direction to the front windshield and set the fan to medium speed. Don’t forget to turn on the external circulation, as it helps expel moisture. If the fog is too severe, first pull over safely, turn on the hazard lights, and then operate the controls. I also make it a habit to warm up the car for a few minutes before driving to balance the temperature difference. After each rain, gently wipe the inside of the windows with a microfiber cloth to prevent dust from trapping moisture. Regularly check the air conditioning filter—if it’s clogged, efficiency drops, so it’s recommended to replace it every six months. Safety comes first, and these small steps have been a great help to me.
