How to Switch Between Internal and External Air Circulation in the New Buick Regal?
3 Answers
The method to switch between internal and external air circulation in the new Buick Regal is by using the air recirculation control button located in the center of the knob on the central control screen. The steps to use the air conditioning system are: 1. Open the windows for ventilation; 2. After starting the vehicle, turn on the fan; 3. Allow the fan to blow natural air for five minutes, then press the air conditioning button to activate the cooling function. The functions of the air conditioning system include: 1. Achieving a cooling effect through the continuous phase change cycle of the refrigerant; 2. Removing dust, odors, and smoke from the air inside the car to freshen the cabin air, and humidifying the air to increase relative humidity. Taking the 2020 Buick Regal as an example, it is a mid-size sedan with the following dimensions: length 4904mm, width 1863mm, height 1461mm, wheelbase 2829mm, fuel tank capacity 55 liters, and trunk capacity 441 liters.
Switching between recirculation and fresh air modes on my Buick Regal is super easy. There's a small button with an arrow on the left side of the steering wheel or in the climate control area, featuring a car icon with a loop inside - that's the recirculation control button. A light press will display "Recirculation" or "Fresh Air" on the instrument cluster or screen, with responsive feedback. I prefer using recirculation mode in city traffic to avoid inhaling exhaust fumes or pollen, while switching back to fresh air mode on highways allows fresh air in and reduces stuffiness. This thoughtful design shows Buick considered different driving environment needs. Additionally, the newer infotainment screens allow deeper settings - select "Mode" in the climate menu to adjust, with options for timers or automatic switching based on air quality, making it both safe and convenient. If the button gets stuck, try restarting the vehicle as this often resolves software glitches. Regular cabin filter maintenance ensures smooth airflow operation - don't wait for problems to occur before servicing.
As a tech enthusiast who frequently tinkers with in-car systems, I've noticed that the new Buick Regal's air recirculation toggle cleverly blends physical buttons with digital control elements. On the air conditioning panel's standard position, there's a "Recirc" button or similar circulation symbol - one press activates interior circulation, another press reverts to exterior; if equipped with a large screen, simply enter the AC menu, locate the "Air Control" option, and toggle the circulation icon. This system relies on interior/exterior sensors to automatically optimize airflow - for instance, detecting high exhaust concentrations will recommend recirculation mode to protect occupant health. The benefits are clear: interior circulation cools faster while saving fuel, exterior circulation prevents windshield fogging for enhanced safety, proving particularly useful during rainy or hazy conditions. I recommend developing a pre-drive check habit to prevent circuit aging issues, with occasional software upgrades to boost response speeds.
