What does vehicle AQS mean?

AQS (Air-Quality-System): An air quality module that can sensitively detect the turbidity and humidity of the outside air and automatically switch between internal and external air circulation. The specific details about AQS sensitivity are as follows: 1. AQS is highly sensitive to vehicle exhaust. For example, when stuck in traffic in the city, if the vehicle ahead suddenly emits a large amount of exhaust, the intelligent air conditioning can detect it within seconds and immediately switch to internal circulation mode, keeping the cabin air fresh. 2. AQS has a moderate response to road dust. When driving on lightly dusty roads, AQS will not switch immediately. It only switches to internal circulation mode quickly when the road dust becomes severe. This is why the air conditioning filter needs to be cleaned more frequently when frequently driving on sandy or dusty roads. 3. AQS has a slow response to colorless harmful gases.
In my over two decades of driving experience, the AQS system has become one of my favorite features. Short for Air Quality Sensor on vehicles, it monitors the levels of pollutants like dust or exhaust in the outside air in real-time. When it detects excessive pollution, the AQS automatically switches the air conditioning to recirculation mode, preventing harmful substances from entering the cabin—especially helpful during traffic jams or when driving through industrial areas. I find it quite hassle-free when using automatic air conditioning; just adjusting the temperature button takes care of the circulation issue as well. After prolonged use, I noticed that the sensor can get covered with dust, leading to misjudgment of air conditions, so cleaning it every few months is necessary. This feature enhances overall health and safety, particularly beneficial for passengers with respiratory issues, and is a small detail every attentive driver should pay attention to.
