Warningwithbrakingfunction
Display
If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster.
The red symbol is displayed and a sigj
nal sounds.
Intervene immediately by braking or make an
evasive maneuver.
Brakingintervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brakj
ing force is used. Prerequisite for the brake
booster is sufficiently quick and hard stepping on the brake pedal. The system can assist with
some braking intervention if there is a risk of a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: during a braking interj
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if vej hicle stability has not been restricted, for inj stance by deactivating the DSC Dynamic Stajbility Control.
The braking intervention can be interrupted by stepping on the accelerator pedal or by acjtively moving the steering wheel.
Object detection can be restricted. Follow the
limitations of the detection range and funcj tional restrictions.
Systemlimits
Safetyinformation WARNING
The system can react not at all, too late,
incorrectly, or without justification due to the system limits. There is a risk of accidents orrisk of damage to property. Follow the informajtion regarding the system limits and actively
intervene, if needed.'

LanedeparturewarningConcept
The lane departure warning alerts when the vehicle on roads with lane markings is about to
leave the lane.
Generalinformation Depending on the country version, the system
issues a warning at speeds between
35 mph/55 km/h and 45 mph/70 km/h.
When switching on the system below this
speed, a message is displayed in the instruj ment cluster.
Warnings are issued by means of a steering
wheel vibration. The time of the warning may
vary depending on the current driving situaj tion.
The system does not provide a warning if the turn signal is set before leaving the lane.
Safetyinformation WARNING
The system does not relieve from perj
sonal responsibility to assess road and traffic
safety. There is a risk of an accident. Adjust
driving style to traffic conditions. Watch traffic
closely and actively intervene where approprij
ate. Do not jerk the steering wheel in response
to a warning.'

Issuedwarning
Ifyouleavethelane
If you leave the lane and if a lane marking has
been detected, the steering wheel vibrates.
If the turn signal is set before changing the lane, a warning is not issued.
EndofwarningThe warning is canceled in the following situaj
tions:'yAutomatically after approx. 3 seconds.'yWhen returning to your own lane.'yWhen braking hard.'yWhen using the turn signal.
Systemlimits
Safetyinformation WARNING
The system can react not at all, too late,
incorrectly, or without justification due to the system limits. There is a risk of accidents or
risk of damage to property. Follow the informaj
tion regarding the system limits and actively
intervene, if needed.'

SafetyinformationWARNING
The system does not relieve from perj
sonal responsibility to assess one's physical state. An increasing lack of alertness or fatiguemay not be detected or not be detected intime. There is a risk of an accident. Make sure
that the driver is rested and alert. Adjust drivj ing style to traffic conditions.'

DrivingstabilitycontrolsystemsVehiclefeaturesandoptionsThis chapter describes all standard, country-specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable laws and regulations
must be observed.
Anti-lockBrakingSystem
ABS
ABS prevents locking of the wheels during
braking.
The vehicle maintains its steering power even during full brake applications, thus increasing
active safety.
ABS is operational every time you start the enj gine.
Brakeassistant When you apply the brakes rapidly, this systemautomatically produces the greatest possible
braking force boost. It reduces the braking disj
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by the Antilock Brake System ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.DSCDynamicStability
Control
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reducj
ing engine speed and by applying brakes to
the individual wheels.
Generalinformation
DSC detects the following unstable driving conditions, for instance:'yFishtailing, which can lead to oversteering.'yLoss of traction of the front wheels, which
can lead to understeering.
Dynamic Traction Control DTC, refer to
page 146, is a version of the DSC where forj
ward momentum is optimized.
Safetyinformation WARNING
The system does not relieve from perj
sonal responsibility to assess the traffic situaj tion. Based on the limits of the system, it canj
not independently react to all traffic situations.
There is a risk of an accident. Adjust driving
style to traffic conditions. Watch traffic closely
and actively intervene where appropriate.'

Generalinformation When DSC is deactivated, driving stability is
reduced during acceleration and when driving in curves.
To increase vehicle stability, activate DSC again as soon as possible.
DeactivatingDSC Press and hold this button but not lonjger than approx. 10 seconds, until the
indicator light for DSC OFF lights up in the inj
strument cluster and displays DSC OFF.
DSC is switched off.
The steering and, depending on the equipj
ment, suspension are tuned for sporty driving.

Indicator/warninglights When DSC is deactivated, DSC OFF is disj
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
DTCDynamicTraction
Control
Concept
DTC is a version of the DSC Dynamic Stability Control where forward momentum is optij mized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
for instance unplowed snowy roads, but with
somewhat limited driving stability.
When DTC is activated, the vehicle has maxij
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Drive carefully.
You may find it useful to briefly activate DTC
under the following special circumstances:'yWhen driving in slush or on uncleared,
snow-covered roads.'yWhen freeing vehicle from deep snow or driving off from loose ground.'yWhen driving with snow chains.

TRACTION and the DSC OFF indicaj
tor light go out.
xDrive xDrive is the all-wheel-drive system of your vej
hicle. Concerted action by the xDrive and DSC
Dynamic Stability Control further optimizes
traction and driving dynamics. The xDrive all-
wheel-drive system variably distributes the
drive forces to the front and rear axles as dej
manded by the driving situation and road surj
face.
DynamicDampingControl
Concept
This system reduces undesirable vehicle moj tion when using a dynamic driving style or travj
eling on uneven road surfaces.
This enhances the driving dynamics and drivj
ing comfort depending on the road surface
condition and driving style.
ProgramsThe system offers several different programs.
The programs can be selected via Driving Dyj namics Control.
SPORT Consistently sporty control of the shock abj
sorbers for greater driving agility.
SPORT+ Consistently sporty control of the shock abj
sorbers for greater driving agility when driving with limited driving stabilization.COMFORT/ECOPRO
Balanced control of the vehicle.
Variablesportsteering The support offered by the variable sport
steering changes according to the angle by
which the steering wheel has been turned and
the speed.
So, for instance the steering angle of the front wheels is made larger when parking or taking
tight corners. This makes it easier to drive
around bends.
Furthermore, the system provides the steering with more support at low speeds than at higher ones. This makes it easier to park, for instance,and makes steering more direct when drivingat faster speeds.
By taking the angle by which the steering wheel has been turned and the speed into acjcount, a sporty steering response adapted tothe particular driving situation can be achieved.
Servotronic
Concept
Servotronic is a speed-dependent power
steering function.
The system provides the steering force with
more support at low speeds than at higher
ones. This makes it easier to park, for instance,
and makes steering more direct when driving
at faster speeds.
Furthermore, the steering force adapts accordj ing to the driving program, so that a direct,
sporty feel or a comfortable steering response
is conveyed.Seite 147DrivingstabilitycontrolsystemsControls147
