Vehicle features and options
DSC Dynamic Stability
Control
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and
systems, the applicable country provisions
must be observed.
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by applying brakes to
the individual wheels.
General information
Dynamic Stability Control detects, e.g., the fol‐
lowing unstable driving conditions:
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
▷
▷
Fishtailing, which can lead to oversteering.
Loss of traction of the front wheels, which
can lead to understeering.
Dynamic Traction Control DTC, refer to
page 128, is a version of the DSC where for‐
ward momentum is optimized.
The vehicle maintains its steering power even
during full brake applications, thus increasing
active safety.
Safety information
ABS is operational every time you start the en‐
gine.
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the re‐
spective situations.◀
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
WARNING
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
When driving with roof load, e.g., with
roof-mounted luggage rack, driving safety may
not be ensured in driving-critical situations due
to the elevated center of gravity. There is a risk
of accidents or risk of property damage. Do not
deactivate Dynamic Stability Control DSC
when driving with roof load.◀

Indicator/warning lights
DTC is a version of the DSC where forward
momentum is optimized.
The indicator lamp flashes: DSC con‐
trols the drive and braking forces.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
The indicator lamp lights up: DSC has
malfunctioned.
When DTC is activated, the vehicle has maxi‐
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Deactivating DSC: DSC OFF
General information
Therefore, drive with appropriate caution.
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in curves.
You may find it useful to briefly activate DTC
under the following special circumstances:
To increase vehicle stability, activate DSC
again as soon as possible.
