This chapter describes all standard, country-spe‐  
cific and optional features offered with the series.  
It also describes features that are not necessarily  
available in your vehicle, for instance, 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 ob‐  
served.  
The system controls the driving force by auto‐  
matic braking intervention on individual wheels.  
The function corresponds to a differential lock:  
the system detects if a wheel begins to spin, be‐  
cause of loose road surface, for instance and au‐  
tomatically brakes it.  
The driving force is diverted to the wheel with  
better traction.  
As a result, the engine force is transferred more  
efficiently to the wheels during accelerations.  
Anti-lock Braking System  
ABS  
DSC Dynamic Stability  
Control  
ABS prevents locking of the wheels during brak‐  
ing.  
Concept  
The vehicle maintains its steering power even  
during full brake applications, which increases  
the active safety.  
Within the physical limits, the system helps to  
keep the vehicle on a steady course by reducing  
engine speed and by applying brakes to the indi‐  
vidual wheels.  
ABS is operational every time you start the en‐  
gine.  
General information  
DSC detects the following unstable driving con‐  
ditions, for instance:  
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.  
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 163, is a version of the DSC where forward  
momentum is optimized.  
Do not reduce the pressure on the brake pedal  
for the duration of the emergency stop.

Safety information  
Warning  
Deactivating DSC: DSC OFF  
General information  
When DSC is deactivated, driving stability is re‐  
duced during acceleration and when driving in  
curves.  
The system cannot serve as a substitute for the  
driver’s personal judgment in assessing the  
traffic conditions. Based on the limits of the  
system, it cannot independently react to all traf‐  
fic situations. There is a risk of accident. Adjust  
driving style to traffic conditions. Watch traffic  
closely and actively intervene where appropri‐  
ate.  
To increase vehicle stability, activate DSC again  
as soon as possible.  
Deactivating DSC  
Warning  
Press and hold this button but not lon‐  
ger than approx. 10 seconds, until the  
indicator light for DSC OFF lights up in the in‐  
strument cluster and displays DSC OFF.  
When driving with a roof load, for instance with  
roof-mounted luggage rack, the vehicle's cen‐  
ter of gravity is higher, which increases the risk  
of the vehicle tipping in critical driving situa‐  
tions. There may be a risk of accident or risk of  
damage to property. Do not deactivate DSC  
Dynamic Stability Control when driving with  
roof load.  
DSC is switched off.  
Activating DSC  
Press the button.  
DSC OFF and the DSC OFF indicator  
light go out.

Indicator/warning lights  
When DSC is deactivated, DSC OFF is displayed  
in the instrument cluster.  
The indicator light lights up: DSC is de‐

Automatic activation  
When DSC is deactivated, automatic activation  
occurs in the following situations:  
DSC OFF button  
The vehicle has a flat tire.  
When activating cruise control in TRACTION  
or DSC OFF mode.  
Indicator/warning lights  
The indicator light flashes: DSC controls  
the drive and braking forces.

DTC Dynamic Traction  
Performance Control  
Control  
Performance Control enhances the agility of the  
vehicle.  
Concept  
DTC is a version of the DSC Dynamic Stability  
Control where forward momentum is optimized.  
To increase maneuverability, wheels are braked  
individually when a sporty driving style is used.  
The system ensures maximum headway on spe‐  
cial road conditions or loose road surfaces, for in‐  
stance unplowed snowy roads, but with some‐  
what limited driving stability.  
xDrive  
xDrive is the all-wheel-drive system of the vehi‐  
cle. Concerted action by the xDrive and DSC Dy‐  
namic Stability Control further optimizes traction  
and driving dynamics. The xDrive all-wheel-drive  
system variably distributes the drive forces to the  
front and rear axles as demanded by the driving  
situation and road surface.  
When DTC is activated, the vehicle has maxi‐  
mum traction. Driving stability is limited during  
acceleration and when driving in curves.  
Drive carefully.  
You may find it useful to briefly activate DTC un‐  
der the following special circumstances:  
When driving in slush or on uncleared, snow-  
covered roads.  
HDC Hill Descent Control  
When driving off from deep snow or loose  
ground.  
Concept  
Hill Descent Control, HDC, is a downhill control  
feature that controls the vehicle speed on steep  
downhill grades, for instance when driving on un‐  
paved roads.  
When driving with snow chains.  
Deactivating/activating DTC  
Dynamic Traction Control  
When the system is active, the vehicle moves at  
the speed set by the driver, without the driver  
having to depress the brake pedal.  
Activating DTC  
Press the button.  
While HTC is controlling the speed, the system  
automatically distributes the braking force to the  
individual wheels. This improves vehicle drivabil‐  
ity and stability. If necessary, the Antilock Brake  
System prevents the wheels from locking.  
TRACTION is displayed in the instru‐  
ment cluster and the indicator light for DSC OFF  
lights up.  
Deactivating DTC  
General information  
Press the button again.  
Hill Descent Control can be activated at speeds  
below approx. 25 mph/40 km/h.  
TRACTION and the DSC OFF indicator  
light go out.  
Speeds can be set between approx.  
2 mph/3 km/h and approx. 20 mph/30 km/h.  
When the vehicle is moving downhill, the system  
reduces the speed to the set value, within the  
physical limits.

Overview  
Servotronic  
Button in the vehicle  
Concept  
Servotronic is a speed-dependent power steer‐  
ing function.  
The system provides the steering force with  
more support at low speeds than at higher ones.  
This makes it easier to park, for instance, and  
makes steering firmer when driving at faster  
speeds.  
Furthermore, the steering force adapts according  
to the driving program, so that a firm, sporty feel  
or a comfortable steering response is conveyed.

M sports steering  
SPORT  
The M sports steering creates a direct driving  
style by using smaller steering angles. M sports  
steering features variable steering force support  
that takes the speed and transverse acceleration  
into account. This enhances agility and improves  
handling while maintaining a sporty driving style;  
for example, in tight corners or during evasive  
maneuvers. At the same time, it ensures im‐  
proved comfort during parking, turning, and ma‐  
neuvering.
