Indicator/warning lamps
Personal responsibility
The indicator and warning lamps do not
relieve the driver of the responsibility to adapt
his or her desired driving speed and style to
the traffic conditions.◀
The vehicle symbol lights up orange:
A vehicle has been detected ahead of
you.
The vehicle symbol flashes orange:
The conditions are not adequate for
operating the system.
The system was deactivated but applies the
brakes until you actively assume control by
pressing on the brake pedal or accelerator.
The vehicle symbol flashes red and an
acoustic signal sounds:
You are requested to intervene by
braking or making an evasive maneuver.

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 to 110 mph/180 km/h.
The system can also be activated when sta‐
tionary.
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 and the sensor, you
should be alert at all times so that you can in‐
tervene actively, if necessary; otherwise, there
is the danger of an accident occurring.◀
Deceleration
The system does not decelerate for:
▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.
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;
otherwise, there is the danger of an accident
occurring.◀
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.
Seite 140ControlsDriving comfort140
Online Edition for Part no. 01 40 2 909 928 - VI/13
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 consider‐
able delay.
When approaching a curve, the system may
react 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 or
behind bumps in the road.
Radar sensor
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:
▷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 inter‐
ference, 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.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking, for
example.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situation:
▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.
Congestion Assistant
The concept In congestion situations, the system controls
the speed, steers independently and keeps the
vehicle in the lane.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you. The distance that the vehicle
maintains to the vehicle ahead of you can be
varied. For safety reasons, it depends on the
speed. To maintain a certain distance, the sys‐
tem automatically decelerates, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
When lane markings are detected, the system
keeps the vehicle in the lane. For this purpose,
the system steers independently as needed,
for example, during cornering.

When the system is switched on, the current
speed is maintained and stored as the desired
speed.
It is displayed in the speedometer and briefly
displayed in the instrument cluster, Displays in
the speedometer, refer to page 146.
When cruise control is maintained or stored,
DSC Dynamic Stability Control is switched on,
if necessary.
Changing/maintaining speed The rocker switch can be pressed while the
system is interrupted in order to maintain and
store the current speed.
Adapting the desired speed
Adapt the desired speed to the road con‐
ditions and be ready to brake at all times; oth‐
erwise, there is the danger of an accident oc‐
curring.◀
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed if the road is
clear.
▷Each time the rocker switch is pressed to
the point of resistance, the desired speed
increases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi‐
mum of 5 mph/10 km/h.
Max. adjustable speed: 140 mph/230 km/h.▷Pressing the rocker switch to the resist‐
ance point and holding it there accelerates
or decelerates the vehicle without requiring
pressure on the accelerator. After the
rocker switch is released, the vehicle main‐
tains its final speed. Pressing the switch
beyond the resistance point causes the ve‐
hicle to accelerate more rapidly.
Resuming the desired speed
Press the button.
The stored speed is reached and maintained. Displays in the instrument cluster

ped, the indicator lamp in the instru‐

PDC Park Distance ControlThe concept
PDC supports you when parking. Objects that
you are approaching slowly in front of or be‐
hind your vehicle are indicated by:▷Signal tones.▷Visual display.
General information
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 the two rear cor‐
ner 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 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 approaching an object quickly.
Avoid driving away quickly while PDC is not yet
