Driving Stability Control Systems

Vehicle equipment
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment and functions which are not installed in
your vehicle, for example on account of the op‐
tional equipment selected or the country specifi‐
cation. This also applies to safety-relevant func‐
tions and systems. Please comply with the
relevant laws and regulations when using the
corresponding functions and systems.
Anti-lock Brake System
ABS
ABS prevents the wheels from locking when the
brakes are applied.
Steering control is retained even in the event of
full braking, thereby enhancing active road
safety.
ABS is ready to operate each time the engine is
started.
Brake assist
When the brake pedal is depressed quickly, the
system automatically applies maximum braking
power assistance. By doing so, the braking dis‐
tance is kept as short as possible in full braking
situations. The advantages offered by the Anti-
lock Brake System ABS can also be utilised to
the full.
The pressure on the brake should be maintained
for the duration of the full-braking process.

Driving Stability Control Systems

Adaptive brake assist
In conjunction with Active Cruise Control, this
system ensures that the brake responds even
more quickly when braking in critical situations.
Drive-off assistant
Principle
The system provides support when driving off on
upward gradients.
Driving off
1.
2.
The vehicle is held for approximately 2 seconds
after the foot brake has been released.
Depending on the vehicle's load, the vehicle may
roll backwards a little.
Dynamic Stability Control
DSC
Principle
The system reduces engine power output and
applies the brakes on individual wheels thereby
helping, within the limits imposed by the laws of
physics, to keep the vehicle safely on course.
General
DSC detects the following unstable driving con‐
ditions, for example:
▷
Online Edition for Part no. xxx - X/18
Hold the vehicle in place by depressing the
foot brake.
Release the foot brake and drive off without
delay.
Loss of traction at the rear which can lead to
oversteer.
