Technology for driving comfort and safety

Driving stability control

systems

Your BMW is equipped with a series of systems
that help maintain driving stability even in
adverse driving situations.

Antilock Brake System ABS

ABS keeps the wheels from locking during
braking. Steering stability is maintained even
during full brake applications. In this way, active
safety is enhanced.
ABS is operational each time the engine is
started. Braking safely, refer to page

Electronic brake-force distribution

The system controls brake-force application at
the rear wheels in order to obtain increased sta-
bility in the vehicle's braking response.

Dynamic Brake Control DBC

When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. At the same time, the benefits of the ABS
are also exploited.
As long as you want full braking to continue, do
not reduce pressure on the brake.

Dynamic Stability Control DSC

DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.

The laws of physics cannot be repealed
even with DSC. It will always be the

driver's responsibility to drive in a manner that
matches road conditions. Therefore, do not

limit the additional safety margin by practicing
risky driving.

Deactivating DSC

Press the button for at least 3 seconds; the indi-
cator lamp for DSC lights up in the instrument
cluster. Dynamic Traction Control DTC and
DSC have been deactivated simultaneously. No
more interventions to increase stability and for-
ward momentum are carried out.
To enhance vehicle stability, reactivate DSC as
soon as possible.

Activating DSC

Press the button again; the indicator lamp goes
out in the instrument cluster.

Checking

The indicator lamp flashes:
DSC controls the drive forces and
brake forces.

The indicator lamp is lit:
DSC has been deactivated completely.

Dynamic Traction Control DTC

DTC is a variant of the DSC in which forward
momentum is optimized for special road condi-
tions, e.g. snow-covered roads that have not
yet been cleared. The system ensures maxi-
mum forward momentum, but driving stability is
limited. Therefore, drive carefully in accordance
with conditions.
