Dynamic Stability Control DSC

The concept

DSC supports vehicle stability, even in
critical driving situations.

DSC optimizes driving stability and
traction during acceleration and when
you are starting from a standstill. In
addition, it also recognizes unstable
vehicle conditions, such as understeer-
ing and oversteering. By reducing
engine power and applying brakes at
the wheels, DSC helps to keep the
vehicle on a steady course within phys-
ically feasible limits.

The system starts up automatically
each time you start the engine.

The laws of physics cannot be
repealed, even with DSC. The

driver remains responsible for the con-
sequences of any inadequate driving
style. Therefore, do not take any risks
because of the additional safety pro-
vided. Do not make any modifications
to the DSC system. Allow only autho-
rized technicians to perform service
procedures on the DSC.

Indicator lamp for DSC

The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been

switched on, refer to page

> The indicator lamp flashes: DSC is

active and is controlling the drive
torque based on driving conditions

> The indicator lamp does not go out

after the engine is started or lights up
continuously while you are driving:
DSC has been deactivated via the
button or is defective.
Please consult your BMW center for
repairs.

You can continue to drive the vehicle
normally without DSC. In the event of a
malfunction, contact a BMW center or a
workshop that works according to
BMW requirements with appropriately
trained personnel.

To deactivate DSC

Press the DSC button; the DSC indica-
tor lamp lights up continuously. DSC is
switched off.

When better traction is required, it is
beneficial to deactivate the system in
the following situations:
> When rocking the vehicle or starting

off in deep snow or on loose surfaces

> When driving with snow chains.

To maintain vehicle stability,
always drive with the system

switched on whenever possible.

To reactivate DSC

Press the DSC button again; the indica-
tor lamp goes out.
