Dynamic Stability Control
DSC

The concept

This system optimizes driving stability and
traction, especially when just starting off,
when accelerating or when cornering. It
also maintains vehicle stability, even in crit-
ical driving situations.

DSC recognizes unstable vehicle condi-
tions, such as understeering or oversteer-
ing, and, within physically feasible limits,
helps keeping the vehicle on a steady
course by reducing engine speed and by
brake applications at individual wheels.

The DSC is operational every time you start
the engine. It includes the following func-
tions:

Automatic Stability Control plus Trac-
tion ASC+T

Dynamic Traction Control DTC

Dynamic Brake Control DBC

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repealed even with DSC.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. We
therefore urge you to avoid using the addi-
tional safety margin of the system as an
excuse for taking risks.
Do not make any modifications to the DSC
system. Allow only authorized technicians
to perform service procedures on the
DSC.

Indicator lamps

The indicator lamps in the instrument clus-
ter go out shortly after you switch on the
ignition.

Interventions to increase stability are
being performed to a limited degree

only.
