Driving stability control systems
Vehicle features and options
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 laws and regulations
must be observed.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle maintains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, the 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 the Antilock Brake System ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant
In combination with Active Cruise Control, this
system ensures that the brakes respond even
more rapidly when braking in critical situations.
Drive-off assistant
Concept
This system supports driving off on uphill
grades.
Driving away
1. Hold the vehicle in place with the foot
brake.
2. Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle loading or when a
trailer is used, the vehicle may roll back
slightly.
DSC Dynamic Stability
Control
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by braking the individual
wheels.
General information
DSC detects the following unstable driving
conditions, for instance:
▷ Fishtailing, which can lead to oversteering.
▷ Loss of traction of the front wheels, which
can lead to understeering.
Safety information
WARNING
The system does not relieve from per‐
sonal responsibility to assess the traffic situa‐
tion. Based on the limits of the system, it can‐
