Should You Use Internal or External Air Circulation When Driving in Winter Rain?
1 Answers
It is best to use external air circulation when driving in winter rain. Reasons for using external circulation: Using external circulation can expel the steam exhaled by passengers out of the car, preventing cold air from condensing on the windows. If internal circulation is used, it may cause fog to form on the windows, affecting the driver's visibility. How to use external circulation: External circulation allows you to breathe fresh air from outside the car. When driving at high speeds for extended periods, the air inside the car can become stale, making you feel drowsy and less focused. In such cases, you should turn on the external circulation to let outside air in. If the warm air in winter feels too hot, you can turn off the fan and open the external circulation to maintain the interior temperature while enjoying fresh air, which will make you feel more comfortable.
