Driving stability control systems
DSC is also able to detect unstable driving
conditions such as loss of traction at the rear
or vehicle slip over the front wheels. DSC re‐
duces engine output and applies the brakes at
individual wheels, helping, within the limits im‐
posed by the laws of physics, to keep the vehi‐
cle safely on course.
Vehicle equipment
This chapter describes all standard, national
and special equipment provided in the model
series. Equipment not available in the vehicle is
therefore also described, for example the se‐
lected special equipment or national version.
This also applies to safety-relevant functions
and systems. Comply with the relevant na‐
tional regulations when using the correspond‐
ing functions and systems.
Note
Adapting driving style to the prevailing
conditions
It is therefore the driver’s responsibility to
adopt a suitable driving style in every situation.
Anti-lock Brake System,
ABS
ABS prevents the wheels from locking when
the brakes are applied.
Not even DSC can overcome the laws of phys‐
ics.
Do not limit the additional safety afforded by
this system by taking driving risks.◀
Steering control is retained even in the event
of full braking, enhancing active road safety.
Do not deactivate DSC when driving with
a roof load
ABS is ready to operate each time the engine
is started.
Do not deactivate the Dynamic Stability Con‐
trol DSC when driving with a roof load, for ex‐
ample roof rack.
Brake assist
Otherwise, safe driving may no longer be guar‐
anteed in critical situations due to the in‐
creased height of the centre of gravity.◀
When brake is pressed quickly, this system au‐
tomatically applies maximum braking power
assistance. With full braking, this keeps the
braking distance as short as possible. It also
makes full use of the advantages offered by
ABS.
Overview

Dynamic Stability Control,
DSC
Principle
DSC prevents the driven wheels losing traction
when you pull away from rest or accelerate.

Driving stability control systems
DSC OFF button
Dynamic Traction Control,
DTC
Indicator and warning lights
Principle
If indicator light is flashing: DSC is reg‐
ulating the acceleration and braking
forces.
The DTC system is a variant of the DSC opti‐
mised for forward momentum.
In particular road conditions, for example roads
on which snow has not been cleared or uncon‐
solidated ground, system ensures maximum
forward momentum but limited driving stabil‐
ity.
If indicator light is illuminated: DSC has failed.
Deactivate DSC: DSC OFF
Driving stability during acceleration and cor‐
nering is restricted if DSC is deactivated.
Maximum traction is available when Dynamic
Traction Control DTC is activated. Driving sta‐
bility is limited on accelerating and cornering.
To support the driving stability, activate DSC
as soon as possible.
Therefore, drive with the appropriate caution.
Deactivating DSC
In the following exceptional situations it may
be best to activate DTC for a short time:
Press and hold down the button – but
for no longer than approximately
10 seconds – until the DSC OFF indicator light
in the instrument cluster is illuminated and
DSC OFF is displayed.

To increase manoeuvrability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.
proximately walking speed and holds this as
the constant speed.
While the brakes are pressed manually, the
system switches to standby. As a result, sys‐
tem braking does not take place.
Only use HDC in low gears or in selector lever
position D or R.
xDrive
Increasing or reducing speed
xDrive is the four-wheel drive system available
in your vehicle. The combination of xDrive and
DSC further optimises traction and driving dy‐
namics. The xDrive four-wheel drive system
distributes the acceleration forces variably to
the front and rear axles based on the driving
situation and the condition of the road.
Using the rocker switch for Cruise Control on
the steering wheel, set a speed of between ap‐
proximately 6 km/h, 4 mph to approxi‐
mately 25 km/h, 15 mph. The speed of the ve‐
hicle can be changed by slightly pressing on
the gas.

Hill Descent Control HDC
Principle
Press the rocker switch downwards until
the resistance point is reached: when driv‐
ing forwards, the speed is reduced to ap‐
proximately 10 km/h, 6 mph. When driving
backwards, it is reduced to approximately
6 km/h, 4 mph.
The Hill Descent Control function automati‐
cally regulates the speed when driving along
steep inclines. The vehicle moves at a speed
approximately more than walking speed, with‐
out the driver braking.
HDC can be activated under approximately
35 km/h, approximately 22 mph. When driving
downhill, the vehicle reduces the speed to ap‐

Variable sports steering
Display in the instrument cluster
The variable sports steering amplifies the
steering angle of the front wheels when the
steering wheel is fully turned, for example in
tight bends or when parking. The steering be‐
comes more direct.
The speedometer shows the se‐
lected set speed.
▷
Green: the system brakes
the vehicle.
It also varies the force required when steering,
depending on the speed.
▷
Orange: system in standby.
This enables a sports-oriented steering re‐
sponse. In addition, steering is made easier
during parking and manoeuvring.
Malfunction
A message will appear on the instrument clus‐
ter. HDC is not available, for example due to a
high brake temperature.
Servotronic
Dynamic Damper Control
Principle
The Servotronic varies the steering force re‐
quired when steering, depending on the
speed. At low speeds the steering force is
heavily supported, in other words a slight force
is needed when steering With increasing
speed the support for the steering force is re‐
duced.
Principle
The system reduces unwanted vehicle move‐
ments when a dynamic driving style is used or
on uneven roads.
Depending on the condition of the road and
the driving style, this enhances driving dynam‐
ics and driving comfort.

Drive-off assistant
The system provides support when driving off
on upward inclines. It is not necessary to use
the parking brake for this.
1. Hold the vehicle in place by pressing the
foot brake.
2. Release the foot brake and drive off with‐
out delay.
The vehicle is held for approximately 2 sec‐

Depending on the vehicle's load or when tow‐
ing a trailer, the vehicle may roll backwards a
little.
Drive off immediately
After releasing the foot brake, move off
swiftly, as the drive-off assistant will no longer
hold the vehicle after approximately 2 seconds
and it will start to roll back.◀
