Driving stability control systems
Vehicle features and
options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features and functions 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 sys‐
tems. When using these functions and systems,
the applicable laws and regulations must be ob‐
served.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle maintains its steering power even
during full brake applications, which increases
the active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically boosts the vehicle braking capabil‐
ity to the furthest possible extent. It reduces the
braking distance to a minimum during an emer‐
gency stop. This system utilizes all of the capa‐
bilities 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 ACC,
this system ensures that the brakes respond
even more rapidly when braking in critical situa‐
tions.
Drive-off assistant
Concept
This system supports driving off on uphill grades.
Driving off
1.
Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive off without
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 reducing
engine speed and by braking the individual
wheels.
General information
DSC detects the following unstable driving con‐
ditions, for instance:
▷ Fishtailing, which can lead to oversteering.
▷ Loss of traction of the front wheels, which
can lead to understeering.
