Should You Use Recirculation Mode on Rainy Days?

[DelMaverick]

It is better to use the external air circulation mode on rainy days. During rainy weather, when it's cold, the windows tend to fog up, which can obstruct the driver's view. Therefore, it is advisable to first use the external air circulation mode and adjust the airflow direction towards the windshield. Using external circulation helps expel the moisture exhaled by passengers from the vehicle, while the outside cold air is less likely to condense. Here are some important considerations: 1. When the outside air quality is poor or heavily polluted, such as on dusty roads, in congested traffic, or near chemical plants where there are foul odors or unpleasant smells, use the recirculation mode to prevent the poor external air from entering the vehicle; 2. In summer, to quickly cool down the interior with the air conditioning, the recirculation mode can be used; 3. In winter, using the recirculation mode can help keep the interior warmer.
