Driving stability control systems
Antilock Brake System ABS
ABS
prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Adaptive brake assistant
In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical situa‐
tions. Refer also to Collision warning, refer to
page 108.
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.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
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.◀
DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the driving wheels
when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Subject
to physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at individual wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Indicator/warning lamps
The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
Stabilizing interventions by the Integral Active
Steering* system are only performed by the rear
axle steering. Seite 95

Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC lights up in the instru‐
ment cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC
Press the button.
DSC OFF and the DSC indicator lamp
go out.
Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The
indicator lamp lights up: DSC is de‐
activated.
DTC Dynamic Traction
Control
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 slush or on uncleared,
snow-covered roads.
▷ When rocking the vehicle or driving off in
deep snow or on loose surfaces.
▷ When driving with snow chains. Deactivating/activating DTC Dynamic
Traction Control
When dynamic traction control (DTC) is acti‐
vated, there is maximum traction on loose road
surfaces.The TRACTION* program is acti‐
vated.The driving stability is limited during ac‐
celeration and during cornering.
Activating DTC
Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
lights up.
Deactivating DTC
Press the button again.
TRACTION
and the DSC indicator lamp
go out.
Indicator/warning lamps
When DTC is activated, TRACTION is displayed
in the tachometer.
The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
xDrive*
xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
HDC Hill Descent Control*
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without requiring brake applica‐
tion, the vehicle moves at slightly more than
twice walking speed. Seite 96

Dynamic Drive*
The concept
Dynamic Drive reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creased
under all driving conditions. The system
utilizes active stabilizer bars on the front and rear
axles that react immediately to all driving situa‐
tions.
Programs
The system offers two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 99.
SPORT
Sporty tuning for greater driving agility.
NORMAL
Comfort-oriented tuning for optimal comfort.
Dynamic Damping Control*
The concept
This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs
The system offers three different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 99.
SPORT
Consistently sporty control of the shock absorb‐
ers for greater driving agility. NORMAL
Balanced tuning between the COMFORT and
SPORT programs.
COMFORT
Comfort-oriented
tuning of the shock absorbers
for optimal traveling comfort.
Integral Active Steering*
The concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in a
direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.
The rear wheels are turned to the same angle as
the front wheels.
In critical situations, Integral Active Steering can
specifically steer the front and rear wheels to
stabilize the vehicle before the driver intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Initializing
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.
1. With the engine running, turn the steering
wheel
all the way to the left and right several
times in a uniform manner until the warning
lamp disappears. Seite 98

relieve the driver of the responsibility to adapt
his
or her desired driving speed and style to the
traffic conditions.◀

brakes until you actively assume control by
pressing on the brake pedal or accelerator.
The vehicle symbol flashes red and an
acoustic signal sounds:
You
are requested to intervene by brak‐
ing or making an evasive maneuver.
System limits
Speed range
Best results are achieved when using the sys‐
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h to 110 mph/180 km/h.
The system can also be activated when station‐
ary.
Comply with the legal speed limit in every situa‐
tion when using the system.
Detection range The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles driving ahead of you
for instance might not be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity,
you should be alert at all times so that you
can intervene actively, if necessary; otherwise,
there is the danger of an accident occurring.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane, e.g., Seite 105

a vehicle at a red traffic light or at the end of traffic
congestion.
The system also does not respond to:
▷
Pedestrians or similarly slow road users.
▷ Red traffic lights.
▷ Stationary objects.
▷ Cross traffic.
▷ Approaching traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle.
You must react yourself; otherwise, there
is the danger of an accident occurring.◀
Swerving vehicles A vehicle driving in front of you is not detected
until
it is completely within the same lane as your
vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a vehi‐
cle driving ahead of you is reliably detected, the
system requests that the driver intervene by
braking and carrying out evasive maneuvers, if
necessary. You must react yourself; otherwise,
there is the danger of an accident occurring.◀ Unexpected lane change
If a vehicle ahead of you unexpectedly moves
into
another lane from behind a stopped vehicle,
you yourself must react, as the system does not
react to stopped vehicles.
Cornering If the desired speed is too high for a curve, the
speed is reduced slightly in the curve, although
curves
cannot be anticipated in advance. There‐
fore, drive into a curve at an appropriate speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not be
detected at all, or not until after a considerable
delay. When approaching a curve, the system may re‐
act
briefly to the vehicles in the next lane due to

Collision warning with
braking function*
The concept
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with an object, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This
warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill. The braking intervention is executed only if DSC
Dynamic Stability Control, refer to page
95, is
switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When
towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.
Switching the warning function on/off Press the button
▷ On: the LED lights up.
▷ Off: the LED goes out.
The state is stored for the remote control cur‐
rently in use.
Configuring the prewarning
After the warning function is switched on, the
following can be set via the iDrive:
▷ The prewarning can be switched on/off.
▷ The time of the prewarning can be set.
These settings have no effect on the time of the
warning from the Active Cruise Control* that
prompts the driver to intervene or brake. Seite 108

System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and ready
to intervene; otherwise, there is the danger of an
accident occurring.◀
Detection range
The detection capacity of the radar sensor and
the collision warning has limitations.
This may result in the warning not being issued
or being issued late.
For example, the following situations may not be
detected:
▷ Slow moving objects when you approach
them at high speed.
▷ Vehicles that suddenly swerve in front of
your vehicle.
▷ Two-wheeled vehicles ahead of you.
▷ Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations: ▷
In heavy fog, rain or snowfall.
▷ In tight curves.
▷ If the radar sensor is dirty or covered.
Prewarning sensitivity
If the prewarning setting is too sensitive, there
may be an excess of false warnings.
Cruise control
The concept
The
system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
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 vehicle
and cause an accident.◀

PDC Park Distance Control*
The concept
In
addition to the PDC Park Distance Control, the
backup camera*, refer to page 113, can be
switched on. PDC supports you when parking. Objects that
you
are approaching slowly in front of or behind
your vehicle are indicated with:
▷ Signal tones.
▷ Visual display.
Measurement
Measurements
are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷ By the front* sensors and the two rear cor‐
ner sensors at approx. 24 in/60 cm.
▷ By the rear middle sensors at approx. 5 ft/
1.50 m.
System limits Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion.
Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:
▷ With tow bars and trailer hitches.
▷ With thin or wedge-shaped objects.
▷ With low objects.
▷ With objects with corners and sharp edges. Seite 111

Low objects already displayed, e.g., curbs, can
move
into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷ In heavy rain.
▷ When sensors are very dirty or covered in
ice.
▷ When sensors are covered in snow.
▷ On rough road surfaces.
▷ In large buildings with right angles and
smooth
walls, e.g., in underground garages.
▷ In heavy exhaust.
▷ Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Select transmission position R with the engine
running.
Switching off automatically
The
system switches off and the LED goes out:
▷ After approx. 160 ft/50 m when driving for‐
ward.
▷ Above approx. 22 mph/36 km/h when driv‐
ing forward.
Switch on the system again if necessary.
Switching on/off manually Press the button.
▷ On: the LED lights up.
▷ Off: the LED goes out.
Signal tones
When approaching an object, an intermittent
tone
is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:
▷ If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.
▷ If moving parallel to a wall.
The signal tone is switched off:
▷ When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.
▷ When transmission position P is engaged.
Volume
You can set the volume of the PDC signal tone,
refer to page 173.
The
setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.
A display appears as soon as Park Distance
Control (PDC) is activated. Seite 112
