How to close the external air inlet when turning sharply?

To close the external air intake of Sharp, you can follow the following steps:

1. Find the control panel in Sharp's car. This panel is located on the dashboard near the driver's seat or near the center console area.

2. Find the buttons or switches related to the air conditioning system on the control panel. Generally speaking, there will be an icon or logo on the control panel, showing the fan or airflow mode.

3. Find the position marked "External Circulation" or "External Air Inlet" on the control panel. The icon of this button usually shows an arrow pointing to the pattern inside the car from the outside.

4. Press the "external circulation" or "external air intake" button to switch it to the closed state. Depending on different models and control panel designs, this button may be a switch, which needs to be pressed once or more to operate.

After the external air inlet is closed, the air conditioning system of the vehicle will not introduce external air into the vehicle, but circulate indoor air. This may be more appropriate in some cases, such as foggy days or poor air quality in the external environment.

If you can't find the relevant buttons on the control panel, I suggest you refer to Sharp's user manual or consult the relevant vehicle maintenance manual. If the problem still exists, you can contact Sharp's dealer or car maintenance expert for help.
