Dynamic Stability Control
DSC
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment which is not installed in your vehicle, for ex‐
ample on account of the optional equipment se‐
lected or the country variant. This also applies to
safety-relevant functions and systems. Please
comply with the relevant laws and regulations
when using the corresponding functions and
systems.
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:
▷ Loss of traction at the rear which can lead to
oversteer.
Anti-lock Brake System
ABS
▷ Loss of grip at the front wheels which can
lead to understeer.
ABS prevents the wheels from locking when the
brakes are applied.
Dynamic Traction Control DTC, see page 177,
is a variant of DSC optimised for forward mo‐
mentum.
Steering control is retained even during full brak‐
ing, thereby enhancing active road safety.
ABS is operational each time the engine is star‐
ted.
Safety notes
WARNING
Brake assist
The system does not relieve you of your per‐
sonal responsibility to assess the traffic situa‐
tion correctly. Due to system limitations, it can‐
not respond independently and appropriately in
all traffic conditions. There is a risk of accident.
Adapt your driving style to the traffic conditions.
Observe the traffic situation and intervene ac‐
tively if the situation warrants it.
When the brake is pressed quickly, this system
automatically applies maximum braking power
assistance. This keeps the stopping distance as
short as possible in full braking situations. The
advantages offered by the Anti-lock Brake Sys‐
tem ABS can also be utilised to the full.
The pressure on the brake should be maintained
for the duration of the full-braking process.
WARNING
When driving with a roof load, for example with
a roof rack, the higher centre of gravity can
mean that driving safety is no longer guaran‐
teed in critical driving situations. There is a dan‐

ger of accidents or damage to property. Do not
deactivate Dynamic Stability Control DSC when
driving with a roof load.
Steering and, depending on equipment, suspen‐
sion are tuned for dynamic driving.
Activating DSC
Overview
Press the button.

lamps are extinguished.

Dynamic Traction Control
DTC
Indicator and warning lamps
Principle
DTC is a variant of Dynamic Stability Control
DSC and is optimised for forward momentum.
If the indicator lamp is flashing: DSC is
regulating the acceleration and braking
forces.
In special road conditions, for example roads on
which snow has not been cleared or on a loose
surface, the system ensures maximum forward
momentum but with somewhat limited driving
stability.
If the indicator lamp is illuminated: DSC has
failed.
Deactivating DSC: DSC OFF
General
Driving stability during acceleration and cornering
is restricted if DSC is deactivated.
Activating DTC provides maximum traction. Driv‐
ing stability during acceleration and cornering is
reduced.
Drive carefully.
To assist driving stability, re-activate DSC as
soon as possible.
It may be useful to activate DTC briefly in the
following exceptional situations:
▷ When driving in slush or on uncleared, snow-
covered roads.
Deactivating DSC
Press and hold the button – but for no
longer than approximately 10 seconds –
until the DSC OFF indicator lamp in the instru‐
ment cluster is illuminated and DSC OFF is dis‐
played.
▷ When starting in deep snow or on a loose
surface.
▷ When driving with snow chains.
DSC is switched off.

Variable sports steering
The support offered by the variable sports steer‐
ing changes according to the angle by which the
steering wheel has been turned and the speed.
xDrive
So, for example the steering angle of the front
wheels is made larger when parking or taking
tight corners. This makes it easier to drive
around bends.
xDrive is the four-wheel drive system of the vehi‐
cle. The combination of xDrive and Dynamic Sta‐
bility Control DSC further optimises traction and
driving dynamics. The xDrive four-wheel drive
system distributes the drive forces variably to the
front and rear axles according to the driving sit‐
uation and road surface conditions.
Furthermore, the system provides the steering
with more support at low speeds than at higher
speeds. This makes it easier to park, for example,
and provides a more direct steering feel when
driving at higher speeds.
Adaptive suspension
By taking both steering wheel angle and vehicle
speed into account, it has been possible to ach‐
ieve a sport steering response adapted to the
particular driving situation.
Principle
The system reduces unwanted vehicle move‐
ments when a dynamic driving style is used or
when driving on uneven roads.
Servotronic
Depending on road conditions and driving style,
driving dynamics and driving comfort are en‐
hanced as a result.
Principle
Servotronic is a speed-dependent power steer‐
ing system.
Programs
It provides different programs.
The system provides more steering force assis‐
tance at lower speeds than at higher speeds.
This makes it easier to park, for example, and
provides a firmer steering feel when driving at
higher speeds.
The programmes can be selected using the Driv‐
ing Experience Control.

Principle
DSC OFF
When you select DSC OFF, see page 177, driv‐
ing stability during acceleration and cornering is
restricted.
The Driving Experience Control allows certain
vehicle characteristics to be adapted. Various
programs can be selected for this purpose. Us‐
ing the Driving Experience Control and using the
DSC OFF button, one programme can be activa‐
ted in each case.
TRACTION
With TRACTION you have maximum traction on
loose surfaces. Dynamic Traction Control DTC,
see page 177, is activated. Driving stability dur‐
ing acceleration and cornering is reduced.
