System limits
Speed range The optimum area of use is on well constructed
roads. The system is functional at speeds be‐
ginning at approx. 20 mph/30 km/h.
The maximum speed that can be set depends
on the vehicle.
Comply with the legal speed limit in every sit‐
uation when using the system.Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity of the camera, you should be alert at all
times so that you can intervene actively, if nec‐
essary; otherwise, there is the danger of an ac‐
cident occurring. ◀
Deceleration The system does not decelerate for:
▷Pedestrians, cyclists or similar slow road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.▷Unlit vehicles or vehicles with defective
lighting at night.Seite 94ControlsDriving comfort94

Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if necessary. You must react yourself; oth‐
erwise, there is the danger of an accident oc‐
curring. ◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly in the curve, although
curves cannot be anticipated in advance.
Therefore, drive into a curve at an appropriate
speed.
In tight curves, situations may result due to the
restricted detection range of the system in
which a vehicle driving ahead of you may not
be detected at all, or not until after a considera‐
ble delay.
When approaching a curve, the system may re‐
act briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Malfunction A Check Control message is displayed if the sys‐
tem fails or was automatically deactivated.
The system may not be fully functional in the
following situations:
▷If an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the camera view field or the front wind‐
shield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.Seite 95Driving comfortControls95

Cruise controlThe 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
Depending on the set drive mode, refer to
page 88, the characteristics of the cruise con‐
trol can change in certain areas.

PDC Park Distance Con‐
trol
The concept
PDC supports you when parking. Slowly ap‐
proaching an object behind or, with the appro‐ priate equipment, also in front of your vehicle issignaled by signal tones:
General information Measurements are made by ultrasound sensors
in the bumpers.
The range, depending on the environment, is
approx. 6 ft/2 m.
An acoustic warning is first given:▷By the front middle sensors and the two
corner sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx.
5 ft/1.50 m.
Hints
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 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. ◀

Display
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 be‐
hind the vehicle, an alternating continuous sig‐
nal is sounded.
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, Enter‐
tainment and Communication.
The setting is stored for the remote control cur‐
rently in use.
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.▷When there is snow.▷For objects with porous surfaces.
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.▷On uneven surfaces, such as speed bumps.▷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.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.
Malfunction
A Check Control message, refer to page 57, is
displayed in the instrument cluster.
PDC has failed. Have the system checked.
To ensure full operability:
▷Keep the sensors clean and free of ice.▷Do not adhere any stickers to the sensors.Seite 99Driving comfortControls99
Online Edition for Part no. 01 40 2 925 116 - X/13
Page 104 of 233

▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Parking assistant
The concept
This system assists the driver in parking parallel
to the road.
Ultrasound sensors measure parking spaces on
both sides of the vehicle.
The parking assistant calculates the best possi‐
ble parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information issued by the PDC and the
parking assistant and accelerate or brake ac‐
cordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 98.
Hints Personal responsibility
Even an active system does not relieve
the driver from personal responsibility for the
driving process.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Continuously and attentively monitor the driv‐
ing process, the area surrounding the vehicle
and the traffic situation, and actively intervene
when required, otherwise, there is a risk of an
accident. ◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the
system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring. ◀
Transporting loads
Loads that extend beyond the perimeter
of the vehicle are not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the danger of an acci‐
dent occurring. ◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curbs.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged. ◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
For measuring parking spaces▷Maximum speed while driving forward ap‐
prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.▷When parking in parking spaces on the
driver's side, the corresponding turn signal
must be set.Seite 100ControlsDriving comfort100
