Display
The collision warning can be issued in the in‐
strument cluster, in the Head-up Display*, and
acoustically.
Instrument cluster
The vehicle lights up in red: prewarning
The vehicle flashes red and an acoustic
signal sounds: acute warning
You
are requested to intervene by brak‐
ing or making an evasive maneuver.
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 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 119, 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 115

Side View*
The concept
Side View provides an early look at cross traffic
at
blind driveways and intersections. Road users
concealed by obstacles to the left and right of
the vehicle can only be detected relatively late
from the driver's seat. To improve visibility, two
cameras in the front of the vehicle record the
traffic situation on each side.
System limits
The maximum recording range of the camera is
330 ft/100 m.
Display
The images from both cameras are shown si‐
multaneously on the Control Display.

Check the traffic situation around the ve‐
hicle on blind driveways and intersections with

Heat image
The image shows the heat radiated by objects
in the field of view of the camera.
Warm objects have a light appearance and cold
objects, a dark appearance.
The ability to detect an object depends on the
temperature
difference between the object and
the background and on the level of heat radiation
emitted by the object. Objects that are similar in
temperature to the environment or that radiate
very little heat are difficult to detect.
For safety reasons, when driving at speeds
above approx. 3 mph/5 km/h and in low ambient
light, the image is only displayed when the low
beams are switched on.
A still image is displayed at regular intervals for
a fraction of a second.
Pedestrian detection The pedestrian detection and warning system
only
operates in darkness and only when a heat
image is displayed.
Warm objects that are similar in shape to human
beings are detected by the system.
People detected by the system are displayed
with a slight yellow hue. Under good ambient conditions, the pedestrian
detection
system operates within a range of ap‐
prox. 50 ft/15 m to approx. 330 ft/100 m. Environmental influences can limit the availabil‐
ity of pedestrian detection.
If
pedestrian detection is not available, a symbol
is displayed in the heat image.
This symbol disappears when the function be‐
comes available again.
Warning of people in danger If the system detects a person in the defined
area
in front of the vehicle and if there is the dan‐
ger of a collision with this person, a warning
symbol appears in the Control Display and
Head-up Display*.
Although both the shape and the heat radiation
are analyzed, false warnings cannot be ruled out.
