How to turn on the external circulation in BMW X3?
2 Answers
The button controlling the external and internal circulation in BMW X3 is set to external circulation when no light is on. BMW has labeled the button with the letter A and the letter M. A stands for automatic switching between external and internal circulation (meaning the vehicle detects and controls the circulation itself); M stands for forced internal circulation; when no light is on, it means external circulation. Each press of the button will display corresponding information on the screen. The BMW X3 has body dimensions of 4565mm in length, 1853mm in width, and 1674mm in height, with a wheelbase of 2825mm. Its trunk capacity is 480 liters, which can be expanded to 1500 liters by asymmetrically folding down the rear seats.
Activating the BMW X3's fresh air mode is actually quite simple. Based on my daily driving experience, you just need to locate the recirculation button on the climate control panel - it's the one with an arrow inside a car icon. Press it until the recirculation indicator light turns off, which means you've switched to fresh air mode allowing outside air to flow in smoothly. This operation is very convenient and particularly useful in winter or rainy days to prevent windshield fogging and maintain clear visibility. I often use this feature on highways to refresh cabin air and reduce stuffiness. If you're unfamiliar with the button location, check the center console area near the steering wheel - the X3's design is user-friendly with responsive buttons. From a safety perspective, fresh air mode helps reduce fatigue driving risks as continuous fresh air intake improves concentration. Once you master this basic operation, you can easily enjoy comfortable driving in daily use. Overall, BMW X3 performs well in this aspect, making it easy for beginners to get started quickly.
