ASC+T/DSC
*
Automatic Stability Control plus
Traction (ASC+T)/Dynamic
Stability Control (DSC)
*
These systems help provide additional
dynamic stability, particularly when ac-
celerating and cornering.
The DSC system enhances the benefits
of the ASC+T. In addition to optimizing
vehicle stability and traction when ac-
celerating 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.

Indicator lamp
The indicator light in the instru-
ment cluster goes out shortly af-
ter you switch on the ignition.
Refer to page 21 .
Indicator lamp flashes:
The system is actively regulating drive
torque in response to monitored vehicle
operating conditions.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving:
If the system has not been deactivated,
there is a system malfunction. The vehi-
cle 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.
We recommend that you deactivate the
system for increased traction:
> When rocking the vehicle or starting
off in deep snow or on loose surfaces
> or when driving with snow chains.
Refer also to page
129 .
To reactivate the system
Press the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with ASC+T/DSC.
Any consequences arising from traction
loss due to excessive vehicle speed re-
main the responsibility of the driver. For
this reason, do not take risks, using the
additional safety margin provided by the
system as an excuse.
