This chapter describes all standard, country- specific and optional features offered with theseries. It also describes features that are notnecessarily available in your vehicle, e. g., due
to the selected options or country versions.
This also applies to safety-related functions
and systems. When using these functions and systems, the applicable country provisions
must be observed.

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 within the
given system limits so that the set distance to
the vehicle ahead is maintained.
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 features of the cruise control can change in certain
areas.Safety
information
WARNING
The system does not release from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sysj tem, it cannot independently react to all trafficsituations. There is a risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively intervene in the rej
spective situations.'

Setting
the
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 134.
DSC will be switched on, if needed.
The speed can also be stored by pressing 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 point of resistance, the desired
speed increases or decreases by a maxij
mum 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 release from the
personal responsibility. Due to the system limj its, braking can be late. There is a risk of accijdents or risk of property damage. Be aware tothe traffic situation at all times. Adjust the disj
tance to the traffic and weather conditions and maintain the prescribed safety distance, possij
bly by braking.'

Reduce
distancePress button repeatedly until the dej
sired distance is set.
Instrument cluster will display selected disj tance, refer to page 134.
Increase
distance Press button repeatedly until the dej
sired distance is set.
Instrument cluster will display selected disj tance, refer to page 134.
Continuing
cruise
control
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.

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 staj tionary obstacle is located in the same lane, e.g., a vehicle at a red traffic light or at the endof 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.
Swerving
vehicles
A vehicle driving in front of you is not detected until 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. This also applies to major speed differj
ences to vehicles driving ahead of you, e.g., when rapidly approaching a truck. When a vej
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneuj
vers, 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.
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 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
In the event of unfavorable weather and light
conditions, e.g., if there is rain, snowfall, slush, fog or glare, this may result in poorer recognijtion of vehicles as well as short-term interrupj
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.,by braking, steering or evading.
Engine
powerThe 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, e.g., during parkj
ing.
A Check Control message is displayed if the system fails.

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 141.
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.Seite 139Driving
