Dynamic Traction Control
DTC
The concept
The
DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:
▷ When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces ▷
When rocking a vehicle free or starting off in
deep snow, sand, or on loose ground
▷ When driving with snow chains*.

xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv‐
ing characteristics. The 4-wheel drive system
xDrive
variably distributes the drive forces to the
front and rear axle depending on the driving sit‐
uation and prevailing road conditions.
Dynamic Performance
Control*
The concept
Dynamic Performance Control optimizes the
handling characteristics of your vehicle when
starting off, cornering, and during evasive ma‐
neuvers.
To achieve this, the system variably distributes
the drive torque of the rear axle to the two rear
wheels. This further increases the steering pre‐
cision and tracking stability of your vehicle.
Display
The Control Display shows how xDrive and Dy‐
namic Performance Control are distributing the
drive forces.
1. "Vehicle Info" 2.
"Torque distribution" The current distribution of drive forces is indi‐
cated by arrows pointing to all four wheels.
The highlighted arrows show the drive forces
currently present. The longer an arrow is, the
greater
the drive forces in the associated wheel.
The transparent arrows indicate the maximum
value the drive forces over the last 10 seconds.
Malfunction

Hill Descent Control HDC
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. The vehicle moves at approxi‐
mately walking speed without braking
intervention by the driver.
You can activate the Hill Descent Control at
speeds below approx. 22 mph/35 km/h. When
moving downhill at speeds below approx.
22 mph/35 km/h, the vehicle reduces its speed
to approximately walking speed, approx. 5 mph/
8 km/h and keeps it constant.
Only use HDC in transmission positions D or R.
Increasing or reducing speed
The speed can be changed in the range from
approx. 4 mph/6 km/h to approx. 15 mph/25 km/
h by pressing the accelerator or brake pedal
lightly.

When driving on poor roads, avoid using
full throttle or pressing the accelerator beyond
the kickdown point and also avoid heavy brak‐
ing. Otherwise, the drive train may be damaged
or accidents can occur.◀
Adaptive Drive*
The concept
Adaptive Drive reduces the body roll which oc‐
curs when cornering quickly or during fast eva‐
sive maneuvers. In addition, Adaptive Drive re‐
duces
the steering angle requirement, improves
the running comfort, and enhances the dynamic

Drive-off assistant
This
system supports driving away on gradients.
The parking brake is not required.
1. Hold the vehicle in place with the foot brake.
2. Release the foot brake and drive away with‐
out delay.
Depending on the vehicle load, the vehicle may
roll back slightly. Driving off without delay
After
releasing the foot brake, start driving
without delay, since the drive-off assistant will
not hold the vehicle in place for more than ap‐
prox. 2 seconds and the vehicle will begin rolling
back.◀
Self-leveling suspension*
The concept
The self-leveling suspension on the rear axle
assures a continuous ground clearance.
To do so, the height of the vehicle is measured
by sensors at both rear wheels.
If the actual height deviates from the defined
height, such as due to cargo in the vehicle, this
difference is compensated very quickly. In ad‐
dition, spring motions resulting from cornering
or irregularities in the road surface are reduced
to a minimum.
The system works automatically.
Malfunctions
Malfunctions are displayed via Check Control,
refer to page 76.
Active steering*
The concept
The active steering actively varies the steering
angle of the front wheels in relation to the steer‐
ing wheel movements. In addition, it also varies
the steering force required for steering depend‐
ing on the vehicle's speed.
When you are driving in the low speed range, for
instance in a town or when parking, the steering
angle increases, i.e., steering becomes very di‐
rect. In the higher speed range, on the other
hand, the steering angle is reduced more and
more. This improves the handling of your vehicle
over the entire speed range.
In critical situations, the system can make tar‐
geted corrections to the steering angle provided Seite 100

by the driver and thus stabilize the vehicle before
the driver intervenes.
Malfunction
The
warning lamp lights up yellow and
a message is shown on the Control
Display. The active steering is defec‐
tive or has been temporarily deacti‐
vated. At low speeds, greater steering wheel
movements are required, whereas at higher
speeds, the vehicle reacts more sensitively to
steering wheel movements. The stability-pro‐
moting intervention can also be deactivated.
Proceed cautiously and drive defensively.
Deactivation
Active steering deactivates in order to carry out
an initialization. This deactivation is displayed by
means of a message. The initialization can take
several minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
In the event of a defect, a corresponding text
message is displayed. Have the system
checked. Seite 101

Driving comfort
Active cruise control*
With active cruise control you can select a de‐
sired speed which is then automatically main‐
tained when driving on open roadways and is
varied
to maintain a selected distance setting to
slower moving vehicles ahead.
Active cruise control represents a technological
advance over the familiar cruise control and is a
welcome relief from the constant adjustment of
speed that can accompany driving in traffic on
highways or other high-speed thoroughfares.
Especially on longer trips and in traffic conges‐
tion, the system can reduce fatigue and tension,
while increasing your enjoyment of driving.
Please use it safely and responsibly.
In addition to holding a steady cruising speed, if
you encounter slower vehicles ahead, active
cruise control will, within limits, adjust your ve‐
hicle's speed automatically so that you can flow
with the traffic without having to make constant
adjustments. If, for example, while cruising at the
selected speed, you begin to approach a slower
vehicle ahead of you in the same lane, the sys‐
tem will reduce your vehicle's speed to the same
as that of the vehicle ahead to maintain your se‐
lected distance setting. You can vary the follow‐
ing distance, which will vary with speed. Based
on your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. In addi‐
tion, if the vehicle ahead of you slows to a com‐
plete stop, the system can follow this action
within the given scope and can also accelerate
from a complete stop if the vehicle ahead of you
drives off again shortly thereafter. During brak‐
ing, your vehicle brake lamps will automatically
illuminate to alert a following driver to take ac‐
tion. In addition, it may be necessary for your
vehicle to downshift the automatic transmission
to maintain the distance setting selected. As
soon as the road in front of you has no moving
vehicles, the system will accelerate to your de‐
sired speed. This set speed is also maintained
on downhill grades, however the vehicle speed can drop below the set speed when driving uphill
if the engine output is not sufficient.
Personal responsibility
Active cruise control cannot detect stop
signs,
red lights, or any object that is stopped or
is blocking the road. Active cruise control is not
and must not be used as a collision avoidance/
warning system. Since this active cruise control
system is a new technology and operates dif‐
ferently from conventional cruise control sys‐
tems to which you may be accustomed, it is
necessary that you read all of the pages relating
to this system before use. Carefully read and
observe the information on the system limita‐
tions, refer to page 106, to obtain a good com‐
mand of the system and its range of applica‐
tions.◀
Brake pedal feel
When the system brakes and you also depress
the brake pedal, a somewhat different braking
feel results.
Professional navigation system*
If the vehicle is equipped with a Professional
navigation system, the system adapts the ac‐
celeration and deceleration behavior of the ve‐
hicle to the road on which you are currently driv‐
ing.
To ensure that the system has the latest infor‐
mation on the course of the road, use the most
recent version of the navigation data.
If the vehicle position is unknown, e.g., if you
have left the region covered by the map, the
navigation system ceases to influence vehicle
behavior.
Applications
Please try the system first during sparse traffic
and clear road conditions so that you can get
used to the system. After you have experience
and understand the system, only then use it dur‐
ing normal traffic. Seite 102

As with conventional cruise control systems, ac‐
tive cruise control in no way reduces or substi‐
tutes for the driver's own personal experience,
responsibility, alertness and awareness in ad‐
justing speed, braking or otherwise controlling
the vehicle. The driver should decide when to
use the system on the basis of road, traffic, vis‐
ibility, and weather conditions. Active cruise
control is intended for use on highway-type
roadways where traffic is moving relatively
smoothly as well as in slow-moving traffic con‐
gestion.
Do not use the system in city driving; in
complex driving situations; heavy traffic such as
during rush hour; on curvy, winding roads, slip‐
pery roads or roads with sharp curves such as
highway off-ramps; during inclement weather
such as snow, strong rain or fog; or when enter‐
ing interchanges, service/parking areas or toll
booths. It is also important to regulate your ve‐
hicle's speed and distance setting within appli‐
cable legal limits. Always be ready to take action
or apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you. Otherwise, driving conditions can result
which lead to a violation of the law or elevated
risk of an accident.
The minimum initial activation speed is
20 mph/ 30 km/h, and the maximum speed is
110 mph/ 180 km/h. The system can also be ac‐
tivated while the vehicle is stationary, refer to
page 105.
