Should You Turn Off the External Air Circulation When Parking?

[DeDante]

It mainly depends on the external air environment. If the air quality is good, you don't need to turn it off. However, if you are parking in places with poor air quality, such as a garage, it is better to turn off the external air circulation to prevent the car from being filled with low-quality air, which affects the riding environment. Below is other relevant information: 1. Benefits of turning off external air circulation: When you turn off the external air circulation, it can prevent poor-quality air from outside from entering the car and also help maintain the internal temperature of the car. After turning on the internal air circulation, in areas like underground garages, traffic jams, or sandy and dusty roads, it prevents exhaust fumes, polluted air from garages, and dust from entering the car. 2. The role of external air circulation: External air circulation ventilates the car, allowing stale, oxygen-depleted air inside to be expelled and fresh air to flow in. If you are using the air conditioning in the car, it is recommended to turn on the internal air circulation mode, which can speed up the cooling or heating effect of the air conditioning.
