Adapting your speed and driving style
The display does not relieve the driver of
the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
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 dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐ sued or being issued late.
For example, the following situations may not
be detected:
▷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.▷Pedestrians.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, for example, DSC
OFF.▷If the camera in the mirror or the radar sen‐
sor is dirty or obscured.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant dimming because of
oncoming light, for example, from the sun
low in the sky.
Prewarning sensitivity
Depending on the set prewarning time, this
may result in increased false warnings.
Pedestrian warning with citybraking function
The concept
The system can help to 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 system is controlled via the camera in the
base of the interior mirror.
General information The system issues a warning with brightness
staring at approx. 6 mph/10 km/h to approx.
35 mph/60 km/h regarding a possible risk of
collision with pedestrians and assists with a
brake intervention shortly before a collision.

It responds to persons that are within the de‐
tection range of the system.
Detection range
The warning 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.

Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing lights
up dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.
Notes Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise an
accident is still possible despite all warnings.◀

Attentiveness assistant
The concept The system can detect increasing lack of alert‐
ness or fatigue of the driver during long, mo‐
notonous journeys, for example, on highways.
In this situation, it is recommended that the
driver take 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, for example, steer‐
ing behavior.▷Driving conditions, for example, 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.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.
A recommendation to take a break is displayed
only once during an uninterrupted trip.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:▷When the clock is set incorrectly.▷When the vehicle speed is mainly below
about 43 mph/70 km/h.▷With a sporty driving style, such as during
rapid acceleration or when cornering
quickly.▷In active driving situations, such as when
changing lanes frequently.▷When the road surface is poor.▷In the event of strong side winds.
PreCrash
The concept With this system critical driving situations that
might result in an accident can be detected
above a speed of approx. 20 mph/30 km/h. In these situations, preventative protection
measures are automatically undertaken to
minimize the risk in the event of an accident as
much as possible.
Critical driving situations may include:
▷Full brake applications.▷Severe understeering.▷Severe oversteering.
If the vehicle includes the collision warning or
collision warning with braking feature, impend‐
ing collisions with vehicles driving ahead or
stopped in front of you can also be detected
within the system's range.

Online Edition for Part no. 0140 2 909 827 - VI/13
NotePersonal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways detect critical situations reliably and in a
timely manner. Adapt speed to traffic situation
and drive alertly; otherwise, a risk to safety may
result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:▷The front belts are automatically preten‐
sioned.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.
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.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the ve‐
hicle to brake harder. This interrupts automatic
braking. Depressing the accelerator pedal also
interrupts automatic braking.
After coming to a halt, the brake is released
automatically. Secure the vehicle against roll‐
ing.

Driving stability control systemsVehicle equipmentAll standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
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. This then reduces braking dis‐ tance to a minimum 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.
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. Sub‐ject 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
reduced during acceleration and when driving
in bends.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.
DSC OFF and the DSC OFF indicator
lamp go out.Seite 115Driving stability control systemsControls115

Variable sport steeringThe variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In
addition, it becomes easier to steer during
parking and maneuvering.
Driving Dynamics Control The conceptThe Driving Dynamics Control can be used to
adjust the certain characteristics of the vehicle.
Various programs can be selected for this pur‐
pose. The Driving Dynamics Control and the
DSC OFF buttons can each be used to activate
a program.
