How to Turn on Only the External Air Circulation Without Using the Air Conditioner?

[DelJames]

To turn on only the external air circulation without using the air conditioner, you should turn on the blower and set the circulation mode to external. Below are some additional details: 1. The external circulation mode uses the blower to draw outside air into the car, allowing air to flow between the outside and inside of the vehicle. 2. Shortly after entering the car, you should open the windows or activate the external circulation ventilation system to introduce fresh air. Avoid driving for extended periods with the windows and doors closed, and do not sleep or rest for long periods in a sealed car. 3. When using the air conditioner or heater, opt for the mode that exchanges air between the inside and outside of the car to avoid prolonged use of the internal recirculation mode.
