In vehicles driving at high speed, most of the windows are closed. The vehicle air conditioner has two modes: internal circulation and external air. Timely external ventilation is of great help to the air quality in the vehicle cabin. People in a high-concentration carbon dioxide environment will suffer from inattention, lethargy, drowsiness, and also lead to symptoms such as poor headache reflexes. An accumulation of high level of CO2 is an indication of poor indoor air quality and it could be detrimental to our health without our knowledge.
Through Qui Vive, drivers are reminded to pay attention to ventilation. Always maintain good air quality in the car, maintain every long-distance journey more secure.
