[LeChristian]

Here are the methods for using the internal and external air circulation in a car's air conditioning system: 1. On the control panel of the car's air conditioning, there is a button to switch between internal and external circulation. You can toggle it using this button. 2. When driving in congested urban areas, it is recommended to use the internal circulation mode. For long-distance trips or highway driving, the external circulation mode is advisable. Recommendations for using internal and external air circulation in cars: 1. The car's air conditioning system is equipped with an air filter, which is designed to filter out dust and particulate matter from the air. 2. The air filter needs to be replaced regularly. Failure to replace it for an extended period can result in unpleasant odors in the car's air conditioning and can be harmful to the health of passengers. 3. When replacing the air filter, it is important to choose products from reputable brands.
