Overview
DSC – BMW 325xi
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The system enhances vehicle stability
during acceleration and when starting
up from a full stop, and optimizes trac-
tion as well. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, helps keep the vehicle on a
steady course by reducing the engine
output and brake applications to the
individual wheels.
The DSC is operational every time you
start the engine. DSC contains ADB-X
und DBC, refer to page
118 .
The ADB-X (Automatic Differential
Braking) replaces the function of
conventional differential and transverse
lock through brake intervention, and
increases traction whenever conditions
merit, e.g. when driving on snow-
covered streets.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
started. Refer to pages 21 , 22 .
If the indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC is switched off via the switch;
ADB-X is operational.
ADB-X intervention not indicated.
If the indicator lamp does not go
out after repeatedly pressing the
DSC switch, then the DSC and the
ADB-X are defective, and the interven-
tion described to the right is then no
longer available.
<
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please see your
BMW center. Refer to pages
21 , 22 .
Deactivate the DSC
Press the DSC button; the indicator
lamp comes on and stays on.
The DSC has been switched off and the
ADB-X is designed for maximum
output.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>
When rocking the vehicle or starting
off in deep snow or on loose
surfaces.
>
When driving with snow chains. Refer
also to page
121 .
To maintain vehicle stability,
always drive with the DSC on
whenever possible.
