How to open the car for ventilation?

The simplest method is to open the window for ventilation, press the glass lifting switch and open the window for ventilation; Or find a switch for the internal and external circulation of air in the car, which can be ventilated by external circulation. Open the window for ventilation and adjust the window size according to the vehicle speed. The window opening gap should be small at high speed, and it is not recommended to open the window when driving on expressway. Find the internal and external circulation switch of automobile air and gas, turn the switch to the external circulation position, and turn the temperature adjustment knob to adjust it to the middle position of cold and hot temperature; Push up the air outlet button to open, and then adjust the exhaust direction of the air outlet; Turn the fan adjustment button to set the air volume as required. The function of external circulation is to connect the air inside and outside the car, thus supplementing fresh air. If the external circulation is turned on, connect the air inside and outside the car. When the vehicle is driving, the airflow will be automatically sucked into the vehicle by the wind pressure; When the vehicle is stationary, the air outside the vehicle can enter the blower along the air duct, and then it is blown into the vehicle by the blower, and the air entering the vehicle is discharged from the exhaust hole at the rear of the carriage, thus achieving the effect of circulation.
