Overview

DSC

– BMW 325i

The concept

DSC helps maintain 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, the system recog-
nizes unstable vehicle conditions
(understeering or oversteering, for
example) and helps hold the vehicle on
a sure course by intervening via the
engine and by braking intervention at
the individual wheels.

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

117

The ADB (Automatic Differential
Braking) copies the function of conven-
tional differential and transverse lock
through brake intervention, and
increases traction whenever conditions
merit, e.g. when driving on snow-
covered roads.

If the DSC is switched off the ADB will
still be in ready mode.

Indicator lamp

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

Refer to pages

and

Indicator lamp flashes:
DSC is active and governs the drive
force and braking force.

The indicator lamp lights up continu-
ously:
The DSC has been turned off via the
switch; ADB is ready to use.
ADB intervention is not indicated.

The indicator lamp and the
brake warning lamp lights up
continuously:
The DSC, ADB and DBC have
been switched off via the button
or are defective.

Indicator and warning lamps for
Canadian models.

You can continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center in the event
of a malfunction, refer to pages

and

Deactivate DSC/activate ADB

Press the DSC button briefly, the indi-
cator lamp lights up continuously.

The DSC has been switched off; ADB is
operational.

In the following exceptional circum-
stances, it may be effective to deacti-
vate the ADB for a short period:

When rocking the vehicle or starting
off in deep snow or on loose
surfaces.

When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.

When driving with snow chains.

The gain in traction is achieved by a
reduction in stabilizing intervention.
