System limits
Speed range The system is best used on well-constructed
roads. The system is functional at speeds be‐
ginning at approx. 20 mph/30 km/h.
The max. speed that can be set is
85 mph/140 km/h.
Comply with the legal speed limit and safety
distance in every situation when using the sys‐
tem.Detection range
The detection lidacity of the system and the au‐
tomatic braking lidacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection potential
Because the camera detection system's
potential is limited, you should be alert at all
times so that you can intervene actively, if
needed; otherwise, there is the risk of an acci‐
dent. ◀
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 102CONTROLSDriving comfort102

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 needed. You must react yourself; other‐
wise, there is the risk of an accident. ◀
Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system decelerates
you may compensate it by briefly accelerating.
After releasing the gas pedal the system is reac‐
tivated and controls speed independently.
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:
▷When an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the camera viewing field or the front
windshield 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 103Driving comfortCONTROLS103

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 is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, e.g.:▷On winding 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
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
Depending on the set drive mode, refer to
page 96, the features of the cruise control can
change in certain areas.

PDC Park Distance Con‐
trol
The concept
PDC supports you when parking. When you slowly approach an object with the rear of your
car or with your front - depending on optional
features - a signal tone is sounded:
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on obsta‐
cles and environmental conditions, 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 fast with PDC
Avoid approaching an object too fast.
Avoid driving off fast while PDC is not yet ac‐
tive.
For technical reasons, the system may other‐
wise be too late in issuing a warning. ◀

Display
Signal tones
When approaching an object, an intermittent
sound indicates the position of the object. E. g.
if an object is detected to the left rear of the ve‐
hicle, a signal tone sounds from the left rear
speaker.
The shorter the distance to the object, 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 to the
rear of the vehicle, an alternating continuous
signal is sounded.
The signal tone is switched off, when selector
lever position P is engaged on vehicles with
Steptronic transmission.
Volume
The volume of the PDC signal tone can be ad‐
justed similar to the sound and volume settings
of the radio.
Settings are stored for the profile currently in
use.
System limits
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, e.g.
coats.▷With external interference of the ultra‐
sound, e.g. from passing vehicles or loud
machines.▷When sensors are dirty, iced over, damaged
or out of position.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.▷With tow bars and trailer couplings of other
vehicles.▷With thin or wedge-shaped objects.▷With moving 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.▷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.
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 with
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 automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.Seite 107Driving comfortCONTROLS107
Online Edition for Part no. 01 40 2 961 140 - II/15
Page 112 of 251

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 60, is
displayed in the instrument cluster.
PDC has failed. Have the system checked.
To ensure full functionality:
▷Keep the sensors clean and free of ice.▷dimmedDo not put any stickers on sensors.▷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 react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 106.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of 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 risk of an acci‐
dent. ◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent. ◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
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.Seite 108CONTROLSDriving comfort108
