DSC Dynamic Stability Control
Activating DTC
DSC optimizes vehicle stability during
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 optimal
stability within the limits defined by the
laws of physics.

Press the DSC button briefly; the DTC
indicator lamp in the instrument cluster
lights up continuously.
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, see below.
Deactivating DTC again
Press the DSC button briefly again; the
DTC indicator lamp in the instrument clus-
ter goes out.
Indicator lamp
The indicator lamp goes out soon
after you start the engine.
Switching off DSC
The indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the button.
DTC Dynamic Traction Control
In special driving states, e.g. in deep snow,
DTC ensures maximum forward momen-
tum. The gain in forward momentum also
involves a reduction in driving stability.
DTC is active up to approx. 45 mph/
70 km/h, whereas DSC is only effective to
a limited degree.
Press the DSC button until the DSC indica-
tor light in the instrument cluster lights up
continuously, however not longer than
approx. 10 seconds. DSC and DTC are
deactivated. In addition, the stability pro-
moting intervention of the active steering is
deactivated, refer to page 80.
You may find it useful to briefly activate
DTC under the following special circum-
stances:
>
>
>
When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
A message appears on the Control Display.
Please note any supplementary information
that appears there.
When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
To maintain optimal stability, drive
with the system on whenever possi-
ble.<
When driving with snow chains.
Reactivating DSC
Press the DSC button briefly; the indicator
lamp in the instrument cluster goes out.
