Safety
notesWARNING
The system does not release you from
your personal responsibility to assess the trafj
fic situation correctly. Due to system limitaj
tions, it cannot respond independently in an
appropriate manner in all traffic conditions.
There is a danger of accidents. Adapt your driving style to the traffic conditions. Observe
the traffic situation and intervene actively if the
situation warrants it.'

Safety
noteWARNING
With activated M Dynamic Mode stabilisj
ing engagements are only carried out to a rej duced degree. There is a danger of accident ordamage to property. Adapt to the traffic condijtions. Observe the traffic situation and interjvene actively if the situation warrants it. In theevent of a warning, do not move the steering
wheel with unnecessary force.'

Adaptive
M
suspension
Principle The system reduces unwanted vehicle movej
ments when a dynamic driving style is used or
when driving on uneven roads.
Depending on the road condition and the drivj ing style, this enhances driving dynamics and
driving comfort.

shock absorbers:'y"Comfort": comfort-oriented.'y"Sport": balanced.'y"Sport Plus": consistently sporty.

ServotronicPrinciple
Servotronic is a speed-dependent power
steering system.
The system provides more steering force asj sistance at lower speeds than at higher speeds. This makes it easier to park, for examj
ple, and provides a more direct steering feel
when driving at higher speeds.
In addition, the steering force is adapted acj cording to the drive programme, so that a dijrect, sporty feel or a comfortable steering rejsponse is conveyed.
ProgramsAdjustment possibilities of the steering force:'y"Sport Plus": high.'y"Sport": medium.'y"Comfort": low.

equipment
This chapter describes all standard, national
and special equipment available for the model
series. Therefore equipment which is not inj stalled in your vehicle, for example on account
of the selected optional equipment or the
country specification, may also be described
here. This also applies to safety-relevant funcj
tions and systems. Comply with the relevant
laws and regulations when using the correj
sponding functions and systems.
Cruise
Control
Principle This system allows a desired speed to be setusing the buttons on the steering wheel. The
desired speed is then maintained by the sysj tem. To do this, the system automatically acj
celerates and brakes as necessary.
General
Characteristics of Cruise Control may change
in certain areas depending on vehicle setting.
Safety

The system does not release you from
your personal responsibility to assess the trafj fic situation correctly. Due to system limitajtions, it cannot respond independently in anappropriate manner in all traffic conditions.There is a danger of accidents. Adapt yourdriving style to the traffic conditions.

Dynamic Stability Control DSC is switched on,
if necessary.
Changing
speed
Press the rocker switch repeatedly upwards or downwards until the desired speed is set.
If the system is active, the displayed speed is
stored and the vehicle reaches the stored speed when the road is clear.

the resistance point, the desired speed is increased or decreased by approximately
1 km/h, 1 mph.Seite 156ControlsDriving

ance point and holding up there accelerj ates or decelerates the vehicle without
pressing the accelerator pedal.
The speed is maintained after releasing the rocker switch. Pressing beyond the resistjance point accelerates the vehicle more
rapidly.
Resuming
Cruise
Control
General If Cruise Control is interrupted, it can be rejsumed by calling up the saved speed.
Before calling up the saved speed, make sure
that the difference between the current speed and the saved speed is not excessively large.
Otherwise, there may be inadvertent braking or
acceleration.
The saved speed value is deleted and can no longer be called up in the following instances:
'yWhen the system is switched off.'yWhen the ignition is switched off.

PDC Principle
PDC provides assistance when parking the vej hicle. Slowly approaching an object in behind,or with front PDC, in front of, your vehicle is
signalled by means of:
'yAcoustic signals.'yVisual display.Seite 157Driving
comfortControls157
Online Edition for Part no. 01402981699 - VI/17

GeneralThe ultrasonic sensors for measuring the disjtances are located in the bumpers.
The range is approximately 2 m, 6 ft depending
on the obstacle and environment.
An acoustic warning is only issued in the
following situations:'yAt the front sensors and at the two corner sensors at the rear at a distance of approxijmately 60 cm, 24 in from the object.'yAt the middle sensors at the rear at a disj
tance of approx. 1.50 m, 5 ft from the obj
ject.'yIf there is a collision risk.

Warning
Acoustic
signals An intermittent sound indicates that the vehijcle is approaching an object. For instance, if an
object is identified to the rear left of the vehij
cle, the acoustic signal is output from the rear
left loudspeaker.
The shorter the distance to an object bej comes, the shorter the intervals become.
If the distance to a detected object is less than
approximately 25 cm, 10 in, a continuous tone
sounds.
With front PDC: if there are simultaneously obj jects in front of and behind the vehicle, an alj
ternating continuous tone sounds.
Volume
control
It is possible to set the ratio between the volj
ume of the PDC acoustic signal and the volj
ume of the entertainment source playback.
Via iDrive:
1."My Vehicle"2."iDrive settings"3."Sound"4."Volume settings"5."PDC"6.Set the desired value.
The setting is saved for the currently used
driver profile.
Visual
warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are further away are already displayed before anacoustic signal is given.
A display is superimposed as soon as PDC is
activated.
The recording range of the sensors is shown in
green, yellow and red.
If the rear-view camera image is displayed, it is
possible to change over to PDC:
1.If necessary, tilt the Controller to the left.2. "Rear view camera"

Safety
note WARNING
The system may respond not at all, too
late, incorrectly, or without justification due to limits of the system. There is a danger of accijdent or damage to property. Observe the inforj
mation on the system limits and intervene acj tively if necessary.'

'yIf persons are wearing certain types ofclothing, for example a coat.'yIf there is external disruption to the ultrajsound, for example by passing vehicles orloud machines.'yIf the sensors are dirty, iced-up, damaged

False
alarms
Under the following conditions, the system can
issue a warning although there is no obstacle
in the detection range:
'yIn heavy rain.'yIf the sensors are very dirty or covered with
ice.'yIf the sensors are covered with snow.'yOn rough road surfaces.'yOn uneven ground, for example speed
bumps.'yIn large, rectangular buildings with smooth
walls, for example underground car parks.'yIn washing bays and car washes.'yDue to dense exhaust gases.'yDue to other ultrasonic sources, for examj
ple sweeping machines, steam-jet cleaners
or neon lights.
As soon as the disruption by other ultrasound
sources is no longer present, the system is fully functional again.
Malfunction
A Check Control message is shown.
The recording area of the sensors is shown hatched on the Control Display.
PDC has failed. Have the system checked by a
Service Partner of the manufacturer or another
qualified Service Partner or a specialist workj
shop.
