Concept
Using this system, a desired speed and a disj
tance to a vehicle ahead can be adjusted using
the buttons on the steering wheel.
The system maintains the desired speed on clear roads. For this purpose, the vehicle acj
celerates or brakes automatically.
If a vehicle is driving ahead of you, the system
adjusts the speed of your vehicle so that the
set distance to the vehicle ahead is mainj
tained. The speed is adjusted as far as the
given situation allows.
The distance can be adjusted in several steps.
For safety reasons, it depends on the respecj tive speed.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pej
riod, the system is able to detect this within the given system limits.
General
information Depending on the driving settings, the featuresof the cruise control can change in certain
areas.Safety
information
WARNING
The system does not relieve from perj
sonal responsibility to assess the traffic situaj tion. Based on the limits of the system, it canjnot independently react to all traffic situations.
There is a risk of an accident. Adjust driving style to traffic conditions. Watch traffic closelyand actively intervene where appropriate.'

There is a risk of injuries or danger to life.Watch traffic closely and actively intervenewhere appropriate.'

Interrupting
automaticallyThe system is automatically interrupted in thefollowing situations:'yWhen the driver applies the brakes.'yWhen selector lever position D is disenj
gaged.'yDynamic Traction Control DTC is activated
or DSC Dynamic Stability Control is deactij vated.'yIf DSC Dynamic Stability Control interj
venes.'yWhen SPORT+ is activated with Driving
Dynamics Control.'yIf the safety belt is unbuckled and the drivj
er's door is opened while the vehicle is standing still.'yIf the system has not detected objects for
an extended period, for instance on a road
with very little traffic without curb or
shoulder markings.'yIf the detection range of the radar is imj paired, for instance by dirt or heavy fog.'yAfter a stationary period of approx. 3 secj
onds when the vehicle has been braked to
a stop by the system.
Setting

speed
Maintaining/storing
the
speed
Press the rocker switch while the system is inj terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
The stored speed is displayed in the speedomj
eter and briefly in the instrument cluster, refer
to page 154.
DSC Dynamic Stability Control is switched on,
if necessary.
The speed can also be stored bypressing a button.
Press button.
Changing
the
speed
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 when the
road is clear.
'yEach time the rocker switch is pressed to
the point of resistance, the desired speed increases or decreases by approx.
1 mph/1 km/h.'yEach time the rocker switch is pressed
past the resistance point, the desired
speed changes by a maximum of 5 mph/
10 km/h.
Hold the rocker switch in position to repeat the action.

Adjusting
distance
Safety
information WARNING
The system does not relieve from perj
sonal responsibility. Due to the system limits, braking can be late. There is a risk of accidentsor risk of damage to property. Be aware to thetraffic situation at all times. Adjust the distance
to the traffic and weather conditions and mainj
tain the prescribed safety distance, possibly by
braking.'

pressed because the accelerator
pedal is being pressed; a vehicle
was not detected.Distance control is temporarily supj

Detected
vehicle
Symbol lights up orange:
A vehicle has been detected ahead of
you.
Rolling bars: the detected vehicle has driven
away.
ACC does not accelerate. To accelerate, actij
vate ACC by briefly stepping on the acceleraj
tor pedal or pressing the RES button or the rocker switch.
Indicator/warning
lights Symbol flashes orange:
The conditions are not adequate for
the system to work.
The system was deactivated but applies the brakes until you actively resume control by
pressing on the brake pedal or accelerator
pedal.
Symbol flashes red and a signal
sounds:
Brake and make an evasive maneuver,
if necessary.
System
limits
Detection
range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles driving ahead of you for instance might not be detected.
Deceleration The system does not decelerate when a stajtionary 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 react in the followj
ing situations:
'yFor pedestrians or similarly slow-moving
road users.'yFor red traffic lights.'yStationary objects.'yFor cross traffic.'yFor oncoming traffic.Seite 155Driving

Swerving
vehicles
A vehicle driving in front of you is not detecteduntil it is completely within the same lane as
your vehicle.
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be able to automatically restore the selected disj
tance. It may not be possible to restore the sej
lected distance in certain situations, including if you are driving significantly faster than vehijcles driving ahead of you, for instance when
rapidly approaching a truck. When a vehicle
driving ahead of you is reliably detected, the
system requests that the driver intervene by
braking and carrying out evasive maneuvers, if
needed.
Unexpected
lane
change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehij
cle, 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, although curves canj not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
The system has a limited detection range. Sitj uations can arise in tight curves where a vehij
cle driving ahead will not be detected or will be
detected very late.
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 decelerj
ates you may compensate it by briefly accelerj
ating.
After releasing the accelerator pedal the sysj tem is reactivated and controls speed indej
pendently.
Driving
away In some situations, the vehicle cannot drive off
automatically; for example:
'yOn steep inclines.'yFrom bumps in the road.
In these cases, step on the accelerator pedal.

Weather
The following restrictions can occur under unj
favorable weather or light conditions:'yPoorer vehicle recognition.'yShort-term interruptions for vehicles that
are already recognized.
Examples of unfavorable weather or light conj
ditions:
'yWet conditions.'ySnowfall.'ySlush.'yFog.'yGlare.
Drive attentively, and react to the current traffic situation. If necessary, intervene actively, for
instance by braking, steering or evading.
Engine
power The desired speed is also maintained downhill,but may not be maintained on uphill grades if
engine power is insufficient.
Malfunction
The system cannot be activated if the radar
sensor is not aligned correctly. This may be
caused by damage incurred, for instance durj
ing parking.
A Check Control message is displayed if the system fails.

General
information
An interrupted cruise control can be continued
by calling up the stored speed.
Make sure that the difference between current speed and stored speed is not too large before
calling up the stored speed. Otherwise, uninj
tentional braking or accelerating may occur.
In the following cases, the stored speed value
is deleted and cannot be called up again:'yWhen the system is switched off.'yWhen the ignition is switched off.

Park
Distance
Control Concept
PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is availaj
ble - then the object is reported through:'ySignal tones.'yVisual display.
With appropriate equipment: obstacles on the side of the vehicle that are detected by the
sensors of the parking assistant can also be rej
ported by the PDC. See side protection, refer to page 162.
General
information
The ultrasound sensors for measuring the disj
tances are located in the bumpers.
The maneuvering range, depending on the obj
stacle and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given in the followj
ing situations:
'yBy the front sensors and the two rear corj
ner sensors at approx. 24 in/60 cm from
the object.'yBy the rear middle sensors at a distance to
the object of approx. 5 ft/1.50 m.'yWhen a collision is imminent.'yWith parking assistant: by the side sensors at approx. 24 in/60 cm from the object.Safety
