Dynamic Stability Control
DSC
The concept
This system optimizes driving stability and
traction, especially when just starting off,
when accelerating or when cornering. It
also maintains vehicle stability, even in crit-
ical driving situations.
DSC recognizes unstable vehicle condi-
tions, such as understeering or oversteer-
ing, and, within physically feasible limits,
helps keeping the vehicle on a steady
course by reducing engine speed and by
brake applications at individual wheels.
The DSC is operational every time you start
the engine. It includes the following func-
tions:
>Automatic Stability Control plus Trac-
tion ASC+T
>Dynamic Traction Control DTC
>Dynamic Brake Control DBC
The laws of physics cannot be
repealed even with DSC. It will always
be the driver's responsibility to drive in a
manner that matches road conditions. We
therefore urge you to avoid using the addi-
tional safety margin of the system as an
excuse for taking risks.
Do not make any modifications to the DSC
system. Allow only authorized technicians
to perform service procedures on the
DSC.<
Indicator lamps
The indicator lamps in the instrument clus-
ter go out shortly after you switch on the
ignition.
Dynamic Stability Control DSC indi-
cator lamp flashes:
The system is active and governs
drive torque and braking forces.The indicator lamp stays lit:
Dynamic Stability Control DSC and
Dynamic Traction Control DTC have been
switched off via the button.
Dynamic Traction Control DTC indi-
cator lamp lights up permanently:
DTC has been deactivated via the
DSC button.
Dynamic Stability Control DSC indi-
cator lamp flashes:
Dynamic Traction Control DTC indi-
cator lamp lights up permanently:
DTC is actively regulating drive
torque and braking forces.
Interventions to increase stability are
being performed to a limited degree
only.<
The Dynamic Stability Control DSC
indicator lamp and yellow brake
warning lamp for Dynamic Brake
Control DBC light up continuously:
Dynamic Stability Control DSC,
Dynamic Traction Control DTC and
Dynamic Brake Control DBC are malfunc-
tioning.
Have the system repaired at your BMW
center.
Dynamic Stability Control DSC indi-
cator lamp and yellow brake warn-
ing lamp for Dynamic Brake Control
DBC for Canadian models:
The vehicle remains completely oper-
ational without the DSC, DTC and
DBC functions.<
In the event of a malfunction, please see
your BMW center.
