What does the BC button on BMW mean?
2 Answers
The BC button on BMW is the instrument display function toggle button. During vehicle operation, the driver can press the BC button located on the light control lever under the steering wheel to view or toggle between information such as total mileage, trip distance, instantaneous fuel consumption, remaining range, date, and average fuel consumption on the instrument panel. The buttons on the left side of the steering wheel control multimedia, Bluetooth calls, mute, page switching, track skipping, voice control, call answering and hanging up, and audio source switching. The buttons on the right side control cruise control: SET for setting speed, CANCEL for canceling cruise, RES for resuming cruise, lane keeping system, cruise speed adjustment, and MAIN for the cruise control on/off button. The multifunction buttons on the steering wheel are typically designed for convenient operation by the driver, such as volume adjustment and menu selection. Some models with in-car phone features also have call answer and microphone buttons on the steering wheel. The right side of the steering wheel is for wiper adjustment. When adjusting, push the lever up or down according to the icons on it. The wiper speed can also be adjusted based on the amount of rain. To spray water on the windshield, pull the lever toward the driver. Models with rear wipers can also be adjusted here, with identical indicators. Generally, the dashboard of most vehicles is equipped with four dials: the two largest ones are the tachometer and speedometer, while the two smaller ones are the water temperature gauge and fuel gauge. The small icons on the dashboard represent different meanings and can promptly reflect vehicle information.
As a seasoned driver who has owned several BMWs, I must say the BC button is quite a handy feature. It stands for Board Computer, located near the steering wheel or on the dashboard, and with a light press, it cycles through the displayed information. I often use it to check average fuel consumption, remaining range, total mileage, and more—like monitoring fuel efficiency on long trips to save money and stay informed. Different BMW models may vary slightly in display methods, but its essence is to help drivers stay focused on the road by minimizing the need to look down at screens. Maintenance is simple too—just wipe it regularly to prevent dust buildup that could cause poor contact. Once on the highway, I relied on it to quickly check my remaining fuel range and refuel in time, avoiding an embarrassing breakdown. Overall, this small design may seem minor but is incredibly thoughtful—definitely worth exploring more while driving.
