EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
DSC Dynamic Stability Control
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 contains the functions
DTC Dynamic Traction Control and DBC
Dynamic Brake Control.
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
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.
Activating 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.
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
> When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
> When driving with snow chains.
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now activated.
The DTC indicator lamp in the Info Display
lights up permanently.
When DTC is active, DSC provides
only limited system response up to a
speed of approximately 45 mph/70 km/h.
Intervention for stability enhancement is
reduced.

Deactivating DTC again
Select "Settings". Select "DTC" and con-
firm your selection. DTC is now deacti-
vated. The
DTC indicator lamp in the Info
Display goes out. DSC is once again avail-
able without restriction.
