trol message is displayed.
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.◀
General information
When ECO PRO is activated, cruise control is
also set to a driving style that saves on fuel con‐
sumption.

PDC Park Distance Control
The concept
PDC supports you when parking. Objects that
you are approaching slowly in front of or behind
your vehicle are indicated by:▷Signal tones.▷Visual display.
General information
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 corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
Notes
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.◀

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.
