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

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
General information
The Active Protection safety package consists
of systems that are independent of each other:▷Attentiveness assistant.▷PreCrash▷PostCrash
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.
Note Personal responsibility
The system cannot act as a substitute for
the personal assessment of one's physical
state and may not detect an increasing lack of
alertness or fatigue or may not detect it cor‐
rectly. Therefore, make sure that the driver is
rested and alert; otherwise, risks may be de‐
tected too late and an accident be caused as a
result.◀
Function
The system is activated each time the engine
is started and cannot be switched off.
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.Seite 132ControlsSafety132
Online Edition for Part no. 0140 2 956 218 - X/14
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving withroof load
Do not deactivate Dynamic Stability Control
DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀

DSC OFF button
Indicator/warning lights The indicator lamp flashes: DSC con‐
trols the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in curves.
Stabilizing interventions by the Integral Active
Steering system are only performed by the
rear axle steering.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC
Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.
The DSC system is switched off.
The steering and, depending on the equip‐
ment, suspension are tuned for sporty driving.
Activating DSC Press button.
DSC OFF and the DSC OFF indicator
lamp go out.
Indicator/warning lights
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.Seite 136ControlsDriving stability control systems136

Dynamic Traction Control is switched on.
The driver handles several of the stabilization
tasks.
Activating SPORT+ Press button repeatedly until SPORT+
appears in the instrument cluster and
the DSC OFF indicator lamp lights up.

or activating cruise control, the program auto‐
matically switches to SPORT mode.

Radar sensor
A radar sensor is located in the front bumper for detecting vehicles on the road ahead of the
vehicle.
A dirty or covered sensor may prevent the de‐
tection of vehicles.
▷If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.▷Do not cover the view field of the radar
sensor.
Camera
The camera is found near the interior rearview
mirror.
Keep the windshield in the area behind the in‐
terior rearview mirror clean and clear.
A dirty or covered area in front of the interior
mirror may hinder the detection of vehicles.
If necessary, clean the area in front of the inte‐
rior mirror, e.g., carefully remove salt residue in
the winter.

markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀
Maintaining/storing the speed

System limits
Speed range The system is best used on well-constructedroads.
The minimum speed that can be set is
20 mph/30 km/h. The maximum speed that
can be set depends on the vehicle.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection lidacity of the system and the
automatic braking lidacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection potential
Because of the limited possible detec‐
tion, you should be alert at all times so that you
can intervene if needed; otherwise, there is the
risk of an accident.◀
Deceleration
The system does not decelerate for:▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.
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 ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed. You must react yourself; other‐
wise, there is the risk of an accident.◀
