Active Protection is the BMW ConnectedDrive preventive passenger protection system. After the front seat belts are buckled, they are automatically pretensioned when the car starts moving.
If a critical situation arises on the road, the front seat belts are reversibly pretensioned and the side windows are closed – as is the sunroof, if there is one. With Comfort seats, the front passenger seat backrest is automatically returned to an upright position. A critical situation could include emergency braking, or if the car demonstrates excessive understeer or oversteer.
After certain kinds of accidents, the system is able to automatically apply the brakes and bring the car to a standstill. This helps reduce the likelihood of a second collision or even prevent one altogether.
In addition, the Attentiveness Assistant monitors the driver’s behaviour for signs of fatigue. This system analyses the steering response and reacts to irregular driving behaviour by issuing a message in the Control Display suggesting the driver take a break.
