DSC – BMW 325xi, 330xi

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 car on a steady
course by reducing the RPMs and
brake applications to the individual
wheels.

The DSC is operational every time you
start the engine. DSC contains the
functions of ADB-X and CBC, refer to
page

119

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 roads.

Indicator lamp

The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.

Refer to pages

Indicator lamp flashes:
DSC controls the drive and braking
forces.

Indicator lamp lights up permanently:
DSC has been switched off via the
button; ADB-X is operational.
ADB-X intervention is not indicated.

If the warning lamp does not go
out after pressing the DSC button

repeatedly, then both the DSC and
ADB-X are defective. Consequently,
interventions to increase driving
stability (as described in the preceding
column) are not available.

You can drive perfectly well without
DSC. Please contact your BMW center
in the event of a fault, refer to
pages

Switching the DSC off

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.

To maintain vehicle stability,
always drive with the DSC on

whenever possible.
