The selected distance is displayed in the instru-
ment panel.
Use good judgement to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and State driving
recommendations for safe following distance.
Otherwise, a violation of the law or risk of an
accident could result.<
Interrupting the system
Press the lever up or down and additionally
depress the brake if the vehicle is stationary.
The mark in the speedometer changes color
and the distance indicator goes out.
In addition, the system is interrupted:
>When the brakes are applied
>When transmission position D is disen-
gaged>When DTC is activated or DSC is deacti-
vated
>When DSC is activated
>When the safety belt is unbuckled and the
driver's door is opened while the vehicle is
stationary
>When the system has not detected objects
for an extended period, e. g. on a road with
very little traffic without road edge mark-
ings, or if the radar sensors are dirty, refer to
page72
If the system is interrupted, actively inter-
vene by braking and, if necessary, with
evasive maneuvers; otherwise, there is the dan-
ger of an accident occurring.<
Calling up the stored desired speed and
distance
While driving
Press button4, refer to page68.
All of the displays in the instrument panel lights
up.
While standing
Before leaving the vehicle with the engine
running, engage position P of the auto-
matic transmission and apply the parking brake.
Otherwise, the vehicle may begin to roll.<
If a vehicle detected ahead of you slows to a halt
and your vehicle is also brought to a halt by the
system:
>If the vehicle ahead of you drives away, your
vehicle accelerates automatically as long as
mark 1 for the desired speed in the speed-
ometer is green.
>If the vehicle ahead of you drives away when
mark 1 is orange, depress the accelerator
briefly or press button 4.
Rolling bars in the distance indicator 3
mean that the vehicle ahead of you has
driven away.
If you are standing behind a vehicle with your
brake pedal depressed and the system is deac-
tivated or interrupted: Distance 1, closest
Distance 2
Distance 3
Distance 4, furthest
This distance is set when you acti-
vate the system.
Driving
72 1.Select the desired speed using the lever,
arrow 1 or arrow 2, or press button 4 to
retrieve a stored speed.
2.Release the brake pedal.
3.When the vehicle ahead of you drives away,
press on the accelerator briefly or press
button 4.
Deactivating the system
>When driving, press the lever up or down
twice.
>When stationary, do the same while
depressing the brake pedal.
>Switch off the ignition.
The displays go out, and the stored desired
speed and distance are deleted.

Warning lamps
Display 2 flashes red and a signal
sounds.
The system requests that the you
intervene by braking and carrying
out evasive maneuvers, if neces-
sary. The system cannot independently restore
the distance to the vehicle ahead.
This display does not relieve the driver of the
responsibility to adapt his or her desired driving
speed and style to the traffic conditions.
Display 2 flashes yellow.
The conditions necessary for
operation of the system are no
longer met, e. g. due to ABS or
DSC intervention. 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.
Remove layers of snow and ice carefully.
>Do not cover the view field of the radar sen-
sor.

For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communications
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 must 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.
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. For
instance, two-wheeled vehicles driving ahead
of you might not be detected.
Because of the limitations to the detec-
tion capacity of the system, 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 a
traffic congestion.
The system also does not respond to:
>Pedestrians or similarly slow road users.
>Red traffic lights.
>Stationary objects.
>Cross traffic.
>Approaching traffic.
A warning might not be issued when
approaching a stationary or very slow-
moving obstacle. Take action yourself, other-
wise there is a risk of an accident.<

Signal tones
When nearing an object, the position is corre-
spondingly indicated by an interval tone. Thus,
an object detected to the left rear of the vehicle
will be indicated by a signal tone from the left
rear speaker, etc.
The shorter the distance to the object
becomes, the shorter the intervals become.
If the distance to the nearest object falls to
below roughly 1 ft/30 cm, then a continuous
tone sounds.
If objects are present both in front of and behind
the vehicle, then an alternating, continuous
tone sounds.
An intermittent tone is interrupted after approx.
3seconds:
>When the vehicle remains stationary in front
of an object that has only been detected by
one of the corner sensors
>When driving parallel to a wall
The signal tone is switched off:
>When the vehicle is more than approx.
4.0 in/10 cm away from an object
>When the selector lever is in the P position
Volume
You can adjust the volume of the signal tone,
refer to page87.
The setting is stored for the remote control cur-
rently in use.
Optical warning
The approach to an object can be shown on the

are displayed on the Control Display before a
