Dynamic emergency braking
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
Pulling the parking brake button upward while the vehicle is in motion initiates a defined sequence of dynamic emergency braking regulated by the Dynamic Stability Control (DSC). This function is intended only for emergencies when the driver can no longer decelerate using the brake pedal (for instance, if the master cylinder fails).
Other occupants are also able to bring the vehicle to a standstill in this manner, for example if the driver suddenly loses consciousness. During dynamic emergency braking, hydraulic brake pressure is built up at all four wheel brakes. The brake lamps are activated and the DSC functions assume full operational status. This represents a major advantage when compared against manual parking brakes.
