system activated, resting your foot on the acel‐
erator pedal will cause the system not to brake
even if necessary. Be certain that floormats or
other objects on the vehicle floor do not inter‐
fere with movement of the acccelerator
pedal.◀
Limits of automatic braking
While active cruise control is capable of
braking your vehicle automatically when you
approach a slower vehicle ahead, it is impor‐
tant to be aware that the ability of the system
to apply the brakes is also limited, e.g. when
you reduce your desired speed sharply. lt uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or
when a much slower vehicle cuts in front of
you at close range.◀
Cruise controlThe concept The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
The speed specified using the lever on the
steering column is maintained.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Do not use cruise control
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant 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 vehi‐
cle and cause an accident.◀

Maintaining current speed
Push, arrow 1, or pull, arrow 2, the lever to the
resistance point.
The car's current speed is stored and main‐ tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking ef‐
fect is insufficient on downhill slopes, the sys‐
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
▷Each time the lever is pressed to the point
of resistance, the desired speed increases
by approx. 1 mph/1 km/h.▷Each time the lever is pressed beyond the
resistance point, the desired speed is in‐
creased by up to 5 mph/10 km/h.Seite 118ControlsDriving comfort118

Park Distance Control PDCThe concept
In addition to the PDC Park Distance Control,
the backup camera, refer to page 122, can be
switched on.
PDC supports you when parking. A slow ap‐
proach to an object in front of or behind your
vehicle is announced by:▷Signal tones.▷Visual display.
Measurement
Measurements are made by ultrasound sen‐
sors in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:
▷By the front sensors and two rear corner
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 ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
located outside of the PDC detection range.
Loud noises from outside and inside the vehi‐
cle 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 physi‐
cal limits of ultrasonic measurement, for in‐
stance:▷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 ga‐
rages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
With the engine running or the ignition
switched on, shift the selector lever into posi‐
tion R.
Switching off automatically when
driving forward
The system switches off when a certain dis‐
tance or speed is exceeded.
Switch on the system again if necessary.

▷On: the LED lights up.▷Off: the LED goes out.
Signal tonesWhen approaching an object, an intermittent
tone is sounded that indicates the position of
the object. For example, if an object is de‐
tected behind the vehicle, a signal tone sounds
from the rear speakers.
The shorter the distance to the object be‐
comes, the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and be‐
hind the vehicle, an alternating continuous sig‐
nal is sounded.
The intermittent tone is interrupted after ap‐
prox. 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
You can set the volume of the PDC signal tone,
refer to page 191.
The setting is stored for the remote control
currently in use.
Visual warning
The approach to an object can be shown on
the Control Display. Objects that are farther
away are displayed on the Control Display be‐
fore a signal tone sounds.
The display appears as soon as PDC is acti‐
vated.
If the last image selected was the rear view
camera, this is displayed again. To switch to
PDC:

Detection
Detection is carried out by two cameras
integrated into the exterior mirror and the rear
view camera.
The range is:
Seite 124ControlsDriving comfort124
Online Edition for Part no. 01 40 2 918 395 - III/13
▷Approx. 7 ft/2 m to the side.▷Approx. 7 ft/2 m to the rear.

Side ViewThe 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 from
the driver's seat at the last minute. To improve
visibility, two cameras in the front of the vehi‐
cle record the traffic situation on each side.
System limits
The cameras capture a maximum range of
330 ft/100 m.
Display
The images from both cameras are shown si‐
multaneously on the Control Display.
