Assuming you would like a blog post discussing the BMW BSM (Blind Spot Monitoring) feature:
BSM is a driver assistance feature that uses sensors to monitor your vehicle’s blind spots. When a car is in your blind spot, an icon will illuminate on the corresponding side mirror. If you activate your turn signal while a car is in your blind spot, the icon will flash and an audible warning will sound to alert you of the hazard.
To turn BSM on, press and hold the button with the car and triangle symbol until it illuminates. The BSM system can be turned off by pressing and holding the button again until the light goes out.
BSM can be activated at speeds above 10 mph (15 km/h). The system automatically turns itself off when your vehicle’s speed drops below 6 mph (10 km/h).
The BMW BSM system is a great safety feature that can help prevent accidents. Be sure to familiarize yourself with how it works so that you can take full advantage of its capabilities!
