In case of malfunction
If the brake system warning lamp
lights up in red, together with the
yellow indicator lamps for ABS and
DSC: the stability control is no
longer operational.
If all three lamps light up in yellow:
malfunction in the stability control
systems. The electronic brake-
force distribution is active.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Please have the system checked at the
nearest BMW center.
Check Control messages, refer to page 82 .
Please take note of the additional informa-
tion on the Control Display.

Driving stability control/
DSC Dynamic Stability
Control
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability dur-
ing acceleration and when starting from a
full stop, as well as optimizing traction.
The system recognizes any tendency for
the vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimized
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control.
Indicator lamps
The indicator lamp in the Info Dis-
play goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the Con-
trol Center.
The indicator lamp and the brake
warning lamp remain on continu-
ously:
DSC, DTC and DBC have been
deactivated or a system malfunc-
tion is present.
When the system is off, the stability main-
tenance functions described above are no
longer available. The vehicle will remain
completely operational, however, without
DSC.
Please respond to any malfunctions by
referring the problem to your BMW center.

DTC Dynamic Traction Control
In particular driving situations, in deep
snow, for example, DTC ensures the maxi-
mum forward momentum. The gain in for-
ward momentum in these situations
involves a reduction in vehicle stability.
DTC is active up to 45 mph/70 km/h.
