Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC)*
These systems help provide additional
dynamic stability, particularly when accelerating
and cornering.
The DSC system enhances the benefits
of the ASC+T. In addition to optimizing
vehicle stability and traction when accelerating
or starting from a standstill,
another benefit is realized in cornering
stability. Of course, this is subject to the
limits imposed by the laws of physics.
The system activates automatically
each time you start the engine.

If the system has not been deactivated,
there is a system malfunction. The vehicle
remains operational, but without
ASC+T/DSC. Consult your authorized
BMW center for repair.
To deactivate the system
Press the button. The indicator lamp
will come on.
Depending on equipment options, the
button is marked with ASC or DSC.
With deactivated ASC+T/DSC you are
driving with conventional, unregulated
torque transfer.
The laws of physics cannot be repealed,
even with ASC+T/DSC.
Any consequences arising from traction
loss due to excessive vehicle speed remain
the responsibility of the driver. For
this reason, do not take risks, using the
additional safety margin provided by the
system as an excuse.<

ASC+T/DSC, please refer to the chapter
