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 driv‐
ing situation 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
precision 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

Hill Descent Control HDC The conceptHDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. The vehicle moves at ap‐
proximately walking speed without braking in‐
tervention 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 ap‐
prox. 15 mph/25 km/h by pressing the acceler‐
ator or brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.
On inclines over 10 %, you can reduce the
speed to approx. 3 mph/4 km/h. Pull the lever
of the cruise control beyond the resistance point, arrow 3.1Increasing speed2Pull to the resistance point: reduce the
speed to approx. 4 mph/6 km/h3Pull beyond the resistance point: on in‐
clines over 10 %, reduce the speed to ap‐
prox. 3 mph/4 km/h

Adapting your driving style
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 driving characteristics of your ve‐
hicle.

2.Release the foot brake and drive away
without delay.
Depending on the vehicle load, the vehicle may
roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 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
steering wheel movements. In addition, it also
varies the steering force required for steering
depending 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 be‐
comes very direct. In the higher speed range,
on the other hand, the steering angle is re‐
duced more and more. This improves the han‐
dling of your vehicle over the entire speed
range.
In critical situations, the system can make tar‐
geted corrections to the steering angle pro‐
vided by the driver and thus stabilize the vehi‐
cle before the driver intervenes.
Malfunction The warning lamp lights up yellow
and a message is shown on the Con‐
trol Display. The active steering is de‐
fective or has been temporarily deac‐
tivated. 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 dis‐
played by means of a message. The initializa‐ tion 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 101Driving stability control systemsControls101

Driving comfortVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
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 technologi‐
cal advance over the familiar cruise control and
is a welcome relief from the constant adjust‐
ment of speed that can accompany driving in
traffic on highways or other high-speed thor‐
oughfares. Especially on longer trips and in
traffic congestion, the system can reduce fati‐
gue and tension, while increasing your enjoy‐
ment of driving. Please use it safely and re‐
sponsibly.
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 system will reduce your vehi‐
cle's speed to the same as that of the vehicle
ahead to maintain your selected distance set‐
ting. You can vary the following distance,
which will vary with speed. Based on your se‐
lected distance setting, the system automati‐cally decreases the throttle setting and lightly
applies the brakes if necessary. In addition, if
the vehicle ahead of you slows to a complete
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 transmis‐
sion to maintain the distance setting selected.
As soon as the road in front of you has no mov‐
ing vehicles, the system will accelerate to your
desired speed. This set speed is also main‐
tained on downhill grades, however the vehicle
speed can drop below the set speed when
driving uphill if the engine output is not suffi‐
cient.
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 avoid‐
ance/warning system. Since this active cruise
control system is a new technology and oper‐
ates differently from conventional cruise con‐
trol systems to which you may be accustomed,
it is necessary that you read all of the pages re‐
lating to this system before use. Carefully read
and observe the information on the system
limitations, refer to page 107, to obtain a good
command of the system and its range of appli‐
cations.◀
Brake pedal feel

the distance indicator goes out.
In addition, the system is interrupted:
▷When the brakes are applied.▷When the transmission position D is disen‐
gaged.▷When DTC is activated or DSC is deacti‐
vated.▷When DSC is activated▷When the safety belt and the driver's door
are opened while the vehicle is stationary.▷When the system has not detected objects
for an extended period, e.g., on a road with
very little traffic without road edge line
markings.▷The radar sensor is dirty.
Active intervention if the system is inter‐
rupted
If the system is interrupted, actively intervene
by braking and, if necessary, with evasive ma‐
neuvers; otherwise, there is the danger of an
accident occurring.◀

other objects on the vehicle floor do not inter‐
fere with movement of the acccelerator

Limits of automatic braking
While active cruise control is capable of
braking your vehicle automatically when you
approach a slower vehicle ahead, it is impor‐
tant to be aware that the ability of the system
to apply the brakes is also limited, e.g. when
you reduce your desired speed sharply. lt uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or
when a much slower vehicle cuts in front of
you at close range.◀
Cruise controlThe concept The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
The speed specified using the lever on the
steering column is maintained.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:▷On curvy roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

Maintaining current speed
Push, arrow 1, or pull, arrow 2, the lever to the
resistance point.
The car's current speed is stored and main‐ tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.Seite 109Driving comfortControls109
