rently in use.
Display ▷
Lines, arrow 1: the system is activated.
▷ Arrows, arrow 2: at least one lane marking
was detected and warnings can be issued. Issued warning
If you leave the lane and if a lane marking has
been detected, the steering wheel begins vi‐
brating.
If
the turn signal is set before changing the lane,
a warning is not issued.
End of warning
The warning ends:
▷ Automatically after approx. 3 seconds.
▷ When returning to your own lane.
▷ When braking hard.
▷ When using the turn signal.
System limits 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.◀
The system may not be fully functional in the
following situations:
▷ In heavy fog, rain or snowfall.
▷ In the event of worn, poorly visible, merging,
diverging,

or multiple lane markings such as
in construction areas.
▷ When lane markings are covered in snow,
ice, dirt or water.
▷ In tight curves or on narrow lanes.
▷ When the lane markings are covered by ob‐
jects.
▷ When driving very close to the vehicle in
front of you.
▷ When driving toward bright lights.
▷ When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc. Seite 97

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.
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.
Switching on automatically
Select transmission position R with the engine
running.
Switching off automatically
The

system switches off and the LED goes out:
▷ After approx. 160 ft/50 m when driving for‐
ward.
▷ Above approx. 22 mph/36 km/h when driv‐
ing forward.
Switch on the system again if necessary.
Switching on/off manually Press the button.
▷ On: the LED lights up.
▷ Off: the LED goes out. Seite 108

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 elevated, protruding objects such as
ledges or cargo.
▷ With objects with corners and sharp edges.
▷ With objects with a fine surface structure,
such as fences.
The parking assistant may identify parking
spaces that are not suitable for parking.
Ultrasound sensors The ultrasounds sensors used to measure park‐
ing spaces are located in the side turn signals.
To ensure full operability:
▷
Keep the sensors clean and free of ice.
▷ When using a pressure washer, keep the
sprayer moving and maintain a distance of
at least 12 in/30 cm from the sensors.
Night Vision with pedestrian
detection*
The concept
Night

Vision with pedestrian detection is a night
vision system.
An infrared camera records the area in front of
the vehicle and displays the image on the Con‐
trol Display.
The picture is a heat image. The system has an
integrated pedestrian detection function that
detects pedestrians and cyclists. Warm objects that are similar in shape to human beings are
detected by the system.
Personal responsibility
Night Vision cannot replace the driver's
personal judgment of the visibility conditions
and

the traffic situation. The view ahead and the
actual visibility conditions must always be the
basis on which the vehicle speed is adjusted;
otherwise, there is a risk to road safety.◀
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. Seite 118

The resulting figure equals the available
amount
of cargo and luggage load capacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs pas‐
sengers in your vehicle, the amount of avail‐
able cargo and luggage load capacity is
400 lbs: 1,000 lbs minus 600 lbs = 400 lbs.
5. Determine the combined weight of luggage
and

cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
Load The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷
Heavy cargo: stow as far forward and as low
as

possible, ideally directly behind the cargo
area separating wall.
▷ Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.
▷ Cover sharp edges and corners. Securing cargo
Lashing eyes in the cargo area
To secure the cargo, there are four lashing eyes
in the cargo area
Securing cargo
▷
Smaller and lighter items: secure with re‐
taining straps or with a

cargo net* or draw
straps.
▷ Larger and heavy objects: secure with cargo
straps*.

draw straps on the lashing eyes in the cargo
area.
Securing cargo
Always position and secure the cargo as
described

above; otherwise, it can endanger the
car's occupants if sudden braking or swerving
becomes necessary.
Heavy or hard objects should not be carried
loose inside the car; otherwise, they could be
thrown around as a result of hard braking, sud‐
den swerves, etc., and endanger the occu‐
pants.◀
