Dynamic Stability Control (DSC)
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
DSC starts up automatically each time
you start the engine.
The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional 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 proce-
dures on the DSC. At first, you may
need some time to become accus-
tomed to this system's intervention.
However, it guarantees optimum drive
force and at the same time, the best
possible vehicle stability.<
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 20.
> Indicator lamp flashes: DSC is active
and is controlling the drive torque
based on driving conditions
> If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: DSC has been deacti-
vated via the button or is defective.
You can continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate DSC
Press the button briefly; the indicator
lamp comes on and stays on.
The vehicle does not execute the stabil-
ity-enhancement and traction-control
functions when DSC is deactivated.
We recommend that you deactivate
DSC for increased traction:
> When rocking the vehicle or starting
off in deep snow or on loose surfaces
> When driving with snow chains
> When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
