ver.
Prewarning
This warning is issued, e.g., when there is the
impending danger of a collision or the distance
to the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a relatively high dif‐
ferential speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by an automatic braking intervention
in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Brake intervention, City braking
function
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise is sufficiently quick and hard stepping
on the brake pedal.
The system can additionally assist possibly
with automatic braking intervention if there is
risk of a collision.
At low speeds the vehicle can be decelerated
to a complete stop.
The braking intervention takes place up to ap‐
prox. 50 mph/80 km/h.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
With radar sensor and Active CruiseControl: braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used when the brake is actuated.
Premise is sufficiently quick and hard stepping
on the brake pedal.
The system can assist with automatic braking
intervention if there is risk of a collision.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on.
Above approx. 130 mph/210 km/h the braking
intervention occurs as a brief braking pressure.
No automatic delay occurs.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Detection range
The system's detection potential is limited.
Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐
tected:Seite 143SafetyControls143
Online Edition for Part no. 0140 2 964 330 - VI/15

▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, e.g., DSC OFF.▷If the area of the front windshield in front of
the interior mirror is dirty or covered.▷Depending on equipment, if the radar sen‐
sor is dirty or obscured.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
e.g. the warning time, the more warnings are
displayed. However, there may also be an ex‐
cess of premature warnings.
Pedestrian warning with City
braking function
The concept The system can help prevent accidents with
pedestrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
The camera in the area of the rearview mirror
controls the system.
Active Protection: if a collision seems to be un‐
avoidable, PreCrash functions are triggered.
General information The system warns of possible collisions with
pedestrians at speeds from ap‐
prox. 6 mph/10 km/h to ap‐
prox. 35 mph/60 km/h and supports you with a
braking intervention shortly before a collision.
Under those circumstances it reacts to people
who are within the detection range of the sys‐
tem.
Detection range
The detection area in front of the vehicle is div‐
ided into two areas
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are lo‐
cated within the central area. A warning is is‐
sued about pedestrians who are located within
the extended area only if they are moving in
the direction of the central area.

Display
Warning of people or animals in
danger
If a collision with a person or an animal de‐
tected in this way is imminent, a warning sym‐
bol appears on the instrument cluster and in
the Head-up Display.
Although both the shape and the heat radiation
are analyzed, false warnings cannot be ruled
out.
Warning area in front of the vehicle
The warning area for the pedestrian warning
consists of two parts:
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
With animal warnings, no distinction is made
between the central or expanded area.
The entire area moves along with the vehicle in
the direction of the steering angle and changes
with the vehicle speed. As the vehicle speed
increases, the area becomes longer and wider,
e.g.

▷NBG009014A.
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Brake force display
The concept
▷During normal brake application, the outer
brake lights light up.▷During heavy brake application, the inner
brake lights light up in addition.
Active Protection
The concept
Active Protection prepares occupants and the
vehicle for a possible accident in critical driving
or collision situations.
General information
Active Protection consists of various PreCrash
functions, which can vary depending on the
equipment.
The system is used to detect certain critical
driving situations that might lead to an acci‐
dent. Critical driving situations are:▷Emergency stop.▷Severe understeering.▷Severe oversteering.
Certain functions of several systems can -
within the system limits - lead to Active Pro‐
tection triggering:
▷Collision warning with braking function: de‐
tection of imminent front collisions or auto‐
matic braking intervention.▷Collision warning with braking function or
Night Vision with Dynamic Marker Light:
brake booster.▷Rear collision prevention: detection of im‐
minent rear collisions.
Information
WARNING
The system does not relieve from the
personal responsibility. Due to the system lim‐
its, critical situation could not be detected reli‐
ably or in time. There is risk of an accident. Ad‐
just the driving style to the traffic conditions.
Watch traffic closely and actively interfere in
the respective situations.◀
Function
When the belt is closed, the driver's and pas‐
senger's belt straps are automatically tight‐
ened once after driving away.
In accident-critical situations, the following in‐
dividual functions become active as needed:
▷The front belts are automatically preten‐
sioned.▷Automatic window closing up to a narrow
gap.Seite 160ControlsSafety160
Online Edition for Part no. 0140 2 964 330 - VI/15

▷Automatic closing of the glass sunroof, in‐
cluding sliding visor.▷For vehicles equipped with Comfort seats
in the front: automatic positioning of the
backrest for the front passenger seat.▷For vehicles equipped with Comfort seats
in the rear: automatic positioning of the
backrests for the rear passenger seats.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
Post Crash — iBrake The conceptIn certain accident situations, e.g. collision, the
system can bring the vehicle to a halt automat‐
ically without driver intervention. This can re‐
duce the risk of a further collision and the con‐
sequences thereof.
At standstill After coming to a halt, the brake is released
automatically.
Harder vehicle braking
It can be necessary to bring the vehicle in cer‐
tain situations to a halt quicker.
Here, a higher braking pressure must be gen‐
erated for a short period when pressing the brake pedal than during automatic braking.
This interrupts automatic braking.
Interrupting automatic braking It can be necessary to interrupt automatic
braking in certain situations,e.g. for an evasive
maneuver.
Interrupt automatic braking:
▷By pressing the brake pedal.▷By pressing the accelerator pedal.
Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, e.g., on highways. In this
situation, it is recommended that the driver
takes a break.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess
one's physical state. An increasing lack of
alertness or fatigue may not be detected or not
be detected in time. There is risk of an acci‐
dent. Make sure that the driver is rested and
alert. Adjust the driving style to the traffic con‐
ditions.◀
Function
The system is switched on each time drive
readiness is switched on.
After travel has begun, the system is trained
about the driver, so that increasing lack of alertness or fatigue can be detected.
This procedure takes the following criteria into
account:
▷Personal driving style, e.g., steering behav‐
ior.▷Driving conditions, e.g., length of trip.
Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.

Driving stability control systemsVehicle features and optionsThis chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power 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 greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.Drive-off assistant
This system supports driving off on inclines.
The parking brake is not required.1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
The possible holding duration amounts to
2 minutes.
Depending on the vehicle load or when a trailer
is used, the vehicle may roll back slightly.
DSC Dynamic Stability
Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Information
Adapt your driving style to the situation, for an
appropriate driving style is always the respon‐
sibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.
