Switch DSC off/activate ADB
Press the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is deactivated; ADB is operational.
In the following rare situations, it may
prove useful to deactivate the ADB for a
brief 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.
Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.
Switch the DSC and ADB off
Hold the DSC button down for at least
3 seconds. The indicator and the yellow
brake warning lamps will remain on
continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible.<
To switch DSC and ADB back on
Press the button again; the indicator
lamp or the indicator lamps will go out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.
When ADB is in its standby mode, DSC
is deactivated; DSC does not intervene
to enhance vehicle stability under these
conditions.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Dynamic Brake Control (DBC)
DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.
