vention. The system applies the brakes until you
actively assume control.
Radar sensor
Position
The radar sensor is integrated in the bumper.
Dirty or covered sensor
A
dirty or covered sensor may hinder the detec‐
tion of vehicles.
▷ If necessary, clean the radar sensor. Re‐
move layers of snow and ice carefully.
▷ Do not cover the view field of the radar sen‐
sor.
Malfunction
The
system cannot be activated if the radar sen‐
sor is not aligned correctly. Misalignment may
be caused by damage incurred during parking,
for example.

▷ OAYARS3-A
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions:
▷ This device may not cause harmful interfer‐
ence, and ▷
This device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
System limits
Speed range
Best results are achieved when using the sys‐
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h and 110 mph/180 km/h.
The
system can also be activated when station‐
ary.
Comply with the legal speed limit in every situa‐
tion when using the system.
Detection range The detection capacity of the system and the
automatic braking capacity are limited. Two-
wheeled vehicles driving ahead of you for in‐
stance might not be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity,
you should be alert at all times so that you
can intervene actively, if necessary; otherwise,
there is the danger of an accident occurring.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane, e.g.,
a vehicle at a red traffic light or at the end of traffic
congestion.
The system also does not respond to: Seite 106

▷
Pedestrians or similarly slow road users.
▷ Red traffic lights.
▷ Stationary objects.
▷ Cross traffic.
▷ Approaching traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle. Take action yourself, otherwise there is
a risk of an accident.◀
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 vehi‐
cle driving ahead of you is reliably detected, the
system requests that the driver intervene by
braking and carrying out evasive maneuvers, if
necessary. Take action yourself, otherwise
there is a risk of an accident.◀ Unexpected lane change
If a vehicle ahead of you unexpectedly moves
into
another lane from behind a stopped vehicle,
you yourself must react, as the system does not
react to stopped vehicles.
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. There‐
fore, 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 considerable
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.
Driving away
In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines, with
a heavy trailer or behind bumps in the road.
Driver interventions and your
responsibility
Your
actions have priority at all times. When you
press on the accelerator pedal while driving, au‐
tomatic braking is not performed and the bars in
the distance display go out until you lift your foot
from the accelerator pedal. Once you release the
accelerator pedal, the desired speed is achieved
again on clear roads or the selected distance to
the vehicle ahead is maintained.
Making braking possible
Anytime the driver presses down on the
accelerator pedal, any braking action by the sys‐
tem is interrupted and the distance indicator
goes out until the pedal is fully released. As soon
as you fully release the accelerator, the system
will again control your cruising speed and dis‐
tance setting. While driving with the system ac‐
tivated, resting your foot on the acelerator pedal
will cause the system not to brake even if nec‐
essary. Be certain that floormats or other ob‐
jects on the vehicle floor do not interfere with
movement of the acccelerator pedal.◀
Limits of automatic braking
While active cruise control is capable of
braking your vehicle automatically when you ap‐
proach a slower vehicle ahead, it is important 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 ap‐
proaching a toll booth or when a much slower
vehicle cuts in front of you at close range.◀
Cruise control*
The 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 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.◀

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 effect
is insufficient on downhill slopes, the system 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.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
until the desired speed is reached.
Accelerating significantly:
Press
the lever beyond the resistance point, ar‐
row 1, until the desired speed is reached.
The vehicle accelerates without pressure on the
accelerator pedal. The system stores and main‐
tains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
▷ Each time the lever is pulled to the resist‐
ance point, the desired speed is decreased
by approx. 1 mph/1 km/h.
▷ Each time the lever is pulled beyond the re‐
sistance
point, the desired speed is reduced by up to 5 mph/10 km/h until the minimum
speed of 20 mph/30 km/h is achieved.
The system stores and maintains the speed.
Interrupting the system
Press
the lever up or down, arrow 3: display 1 in
the speedometer changes color, refer to
page 109.
In addition, the system is interrupted:
▷ When the brakes are applied.
▷ When the transmission position D is disen‐
gaged.
▷ When DTC is activated or DSC is deacti‐
vated.
▷ When DSC or ABS is intervening.
Warning lamp The warning lamp lights up if cruise
control has been deactivated auto‐
matically, e.g., by a control interven‐
tion
of the DSC. A message appears on the Con‐
trol Display.
Resuming cruising speed
Press button 4:
The stored speed is resumed and maintained.
Deactivating the system
▷ Press the lever upward or downward twice,

Park Distance Control PDC*
The concept
In addition to the PDC Park Distance Control, the
backup camera*, refer to page 112, can be
switched on.
PDC supports you when parking. A slow ap‐
proach to an object in front of or behind your ve‐
hicle is announced by:
▷ Signal tones.
▷ Visual display.
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 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 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. Seite 110

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. 12 in/30 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
You can set the volume of the PDC signal tone,
refer to page 173.
The
setting is stored for the remote control cur‐
rently 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 before a
signal tone sounds. The display appears as soon as PDC is acti‐
vated.
