Where is the Buick's external circulation button?
1 Answers
Below the center console, there are three knobs. Under the largest middle knob, there are three buttons. The middle button among them controls the internal and external circulation. Pressing the button with its indicator light on means the internal circulation is activated; pressing it again to turn off the indicator light means the external circulation is activated. Below are some precautions regarding the car's internal and external circulation: 1. After purchasing a new car: Just like a newly renovated house, try to maintain air exchange between the inside and outside of the car as much as possible to allow harmful gases inside the car to volatilize and be released as soon as possible. 2. When turning on the air conditioner or heater: Use the mode that exchanges air between the inside and outside of the car, and try to avoid using the internal circulation mode for a long time. 3. In areas with severe traffic congestion: Temporarily switch the air conditioner or heater to the internal circulation mode, and vehicles driving with windows open should temporarily close the windows. Car owners should develop the habit of adjusting the car's air conditioning circulation system in time according to the external air conditions. 4. For the first 6 months after a new car is launched: Strengthen ventilation, clean the car's air conditioner regularly, try to keep the air inside the car fresh, and pay special attention not to use perfume or air freshener to mask any abnormal odors inside the car.
