Where is the internal and external circulation of the 2017 Lavida?

[DelAriana]

The internal and external circulation of the 2017 Lavida is located next to the air conditioning control panel on the dashboard. The following is an introduction to the car's internal and external circulation: Introduction to external circulation: It uses a fan to draw air from outside the car into the interior, meaning the air passages between the outside and inside of the car are connected. The air blown by the fan comes from outside the car, and even if the fan is not turned on, airflow is still drawn into the car while driving, replenishing fresh air inside the car. Introduction to internal circulation: It closes the airflow passage between the inside and outside of the car. Without the fan, there is no airflow circulation, and when the fan is turned on, the airflow drawn in comes only from inside the car, forming an internal airflow circulation within the vehicle.
