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 camera 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 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.Seite 108ControlsSafety108

Warning stages
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention will not bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.

can vary with the people detected. For people
located in the central area, the distance to the
person is indicated by the size of the symbol.
System limits
Basic limits
System operation is limited in situations such as
the following:▷On steep hills, in steep depressions or in
tight curves.▷When the camera is dirty or the protective
glass is damaged.▷In heavy fog, rain or snowfall.▷At very high external temperatures.
Limits of pedestrian detection
Animals are not detected by the pedestrian de‐
tection function, even if they are clearly visible in
the image.
Limited pedestrian detection:
▷People who are fully or partially covered, es‐
pecially when their heads are covered.▷People who are not in an upright position,
e.g., lying down.▷Cyclists on unconventional bicycles (e.g.,
recumbent bicycles).▷After physical damage to the system, e.g.,
after an accident.

Camera
Rain, dirt, snow, or ice can impair camera oper‐
ation.
The camera is automatically heated when the
external temperatures are low.
The camera is automatically cleaned together
with the headlamps.
Clean the lens, refer to page 214.
Lane departure warning
The concept
Starting at a specific speed, this system alerts
you when the vehicle on streets with lane mark‐
ings is about to leave the lane. Depending on the
country-specific version of the vehicle, the
speed is between 35 mph/55 km/h and
45 mph/70 km/h. When switching on the system
below this speed, a message appears in the in‐
strument cluster.
The steering wheel begins vibrating gently in the
event of warnings. The time of the warning may
vary depending on the current driving situation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Notes Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the course
of the road and the traffic situation.
In the event of a warning, do not jerk the steering
wheel, as you may lose control of the vehicle.◀

Signal tones
When approaching an object, an intermittent
tone is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 10 in/25 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.
Volume
The volume of the PDC signal can be adjusted,
refer to user's manual for Navigation, Entertain‐
ment and Communication.
The setting is stored for the remote control cur‐
rently in use.
Visual warning
The approach of the vehicle to an object can be
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis‐
play before a signal tone sounds.
A display appears as soon as Park Distance
Control (PDC) is activated.

System limits
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, e.g.:
▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Malfunction
A Check Control message is displayed.
The range of the sensors is shown as a shaded
area on the Control Display.
PDC has failed. Have the system checked.
To ensure full operability:▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.
Surround View
The concept
Surround View includes the following systems:
▷Backup camera, refer to page 136.▷Side View, refer to page 141.▷Top View, refer to page 139.
It assists the driver when parking, maneuvering
and on blind driveways and intersections.
Backup camera
The concept
The backup camera provides assistance in park‐
ing and maneuvering backwards. The area be‐
hind the vehicle is shown on the Control Display.
Notes Check the traffic situation as well
Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside the picture area of the backup camera. ◀
