Attentiveness assistant
Principle The system can detect increasing inattentive‐
ness or tiring of the driver on long monotonous
drives, for example on motorways. In this situa‐
tion, it is recommended that you take a break.
Note WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing your physical condition. Increasing inatten‐
tion or fatigue might not be detected, or not in
good time. Danger of accidents. Make sure
that the drive is rested and alert. Adapt driving
style to the driving conditions.◀
Function The system is switched on every time the en‐
gine is started and cannot be switched off.
After the start of the drive, the system is adap‐
ted to the driver so that an increase in inatten‐
tion or fatigue can be detected.
This process considers the following criteria:▷Personal driving style, for example, steer‐
ing.▷Drive conditions, for example, time of day,
duration of drive.
The system is active from approxi‐
mately. 70 km/h, 43 mph and can display a rec‐
ommendation to take a break
Recommendation to take a break
With increasing inattention or tiredness of the
driver, an instruction is shown on the control
display with the recommendation to take a
break.
A recommendation to take a break will only be
displayed once during an uninterrupted trip.
After a break, at the earliest another break rec‐
ommendation may be displayed after approxi‐
mately 45 minutes.
System limits
The function may be restricted in situations
such as the following and no warning or a
wrong one is triggered:▷If the time is wrongly set.▷If the speed driven falls considerably below
70 km/h, 43 mph.▷For sporty driving style, for example, with
heavy acceleration or fast cornering.▷In active drive situations, for example, fre‐
quent lane change.▷With bad road conditions.▷With high side-wind.
PreCrash
Principle With the system from 30 km/h/20 mph critical
driving situations may occur, which could
cause an accident. In these situations, auto‐
matically preventative, protective measures
are taken to minimise the risk of accident.
Critical driving situations are, for example:
▷Full braking.▷Heavy understeering.▷Heavy oversteering.
When collision warning or front-end collision
warning with braking function is fitted, within
the limits of the system, threatened collisions
into vehicles in front or stationary vehicles are
detected.
Note WARNING
The system does not take your personal
responsibility from you. Critical situations can‐
not be detected reliably or in good time due to
limitations of the system. Danger of accidents.
Adapt driving style to the driving conditions.
Observe the traffic situation and intervene ac‐
tively if the situation warrants it.◀

WARNING
When driving with a roof load, for exam‐
ple with a roof rack, the higher centre of gravity
can mean that driving safety is no longer guar‐
anteed in critical driving situations. Danger of
accident or damage to property. Do not deacti‐
vate Dynamic Stability Control DSC when driv‐
ing with a roof load.◀
Overview
Button in the vehicle
DSC OFF button
Indicator and warning lights If indicator light is flashing: DSC is reg‐ulating the acceleration and braking
forces.
If indicator light is illuminated: DSC has failed.
Deactivating DSC: DSC OFF
General Driving stability during acceleration and cor‐
nering is restricted if DSC is deactivated.
To support the driving stability, re-activate
DSC as soon as possible.
Deactivating DSC Press and hold down the button – but for
no longer than approximately 10 seconds
– until the DSC OFF indicator light in the in‐
strument cluster is illuminated and DSC OFF is
displayed.
The DSC system is switched off.
Activating DSC Press the button.
The DSC OFF and DSC OFF indicator
lights are not illuminated.
Indicator and warning lights DSC OFF is displayed in the instrument cluster
when DSC is deactivated.
If indicator light is illuminated: DSC is
deactivated.
M Dynamic Mode
M Dynamic Mode allows driving with higher
longitudinal and transverse acceleration on dry
carriageways, but with restricted drive stability.
Only in the absolute limit of the range does the
system engage for stability purposes by re‐
ducing the engine power and by brakes ap‐
plied to the wheels. In this driving situation, ad‐
ditional steering corrections may be required.
WARNING
With activated M Dynamic Mode stabilis‐
ing engagements are only carried out to a re‐
duced degree. Danger of accident or damage
to property. Adapt to the traffic conditions. Ob‐
serve the traffic situation and intervene actively
if the situation warrants it. Do not move the
steering wheel with unnecessary force in case
of warnings.◀
To support the driving stability, re-activate
DSC as soon as possible.
Activating MDM Press the button briefly.

Active M Differential
Principle The active M Differential blocks the rear axis
transmission steplessly, depending on the
drive situation. In so doing, even with the DSC
switched off and in M Dynamic Mode, spinning
of a single rear wheel is avoided and therefore
optimum traction is provided under all driving
conditions.
The driver is responsible for a driving style ap‐
propriate to the situation.
Adaptive M chassis PrincipleThe system reduces unwanted vehicle move‐
ments when a dynamic driving style is used or
on uneven roads.
Depending on the condition of the road and
the driving style, this enhances driving dynam‐
ics and driving comfort.

Park Distance Control PDC
Principle PDC supports you with parking. Slowly ap‐
proaching an object in behind, or with front
PDC, in front of, your vehicle is signalled by
means of:
▷Acoustic signals.▷Visual display.
General
Ultrasonic sensors in each bumper measure
the distance.
The range is approximately 2 m, 6 ft depending on obstacle and environment.
An acoustic warning is only issued under the
following circumstances:
▷At the front sensors and at the two corner
sensors at the rear at approx. 60 cm, 24 in.▷At the central sensors at the rear at ap‐
prox. 1.5 m, 5 ft.▷If there is a collision risk.
Notes
WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing the traffic situation. Due to limits of the sys‐
tem, it cannot respond independently in a rea‐
sonable way in all traffic conditions. Danger of accidents. Adapt driving style to the driving
conditions. Observe the traffic situation and in‐
tervene actively if the situation warrants it.◀
WARNING
If the vehicle is travelling at high speed

Display
Audible warning signals An intermittent sound indicates position of an
object as the vehicle approaches it. For in‐
stance, if an object is identified to the rear left of the vehicle, the warning signal sounds from
the rear left loudspeaker.
The shorter the distance to an object be‐
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 objects in front of
and behind the vehicle, an alternating continu‐
ous tone sounds.
Volume control It is possible to set the ratio between the vol‐
ume of the PDC acoustic signal and the vol‐
ume of the Entertainment.1."Multimedia", "Radio" or "Settings"2."Sound"3."Volume settings"4."PDC"5.Turn the Controller until the desired set‐

System limits
Limits of the ultrasound measurement
Detection of objects might not be possible if
the limits of the physical ultrasound measure‐
ment are exceeded, such as for instance at the
following times:
▷With small children and animals.Seite 132ControlsDriving comfort132
Online Edition for Part no. 01 40 2 964 013 - VI/15

▷With persons with certain clothing, for ex‐
ample a coat.▷With external disruption to the ultrasound,
for example by passing vehicles or loud
machines.▷If the sensors are dirty, iced-up, damaged
or incorrectly adjusted.▷In certain weather conditions, for example
high humidity, rain, snowfall, extreme heat
or strong wind.▷With trailer noses and tow hitches of other
vehicles.▷With thin or wedge-shaped objects.▷With moving objects.▷For higher, protruding objects, for example
projecting walls or loads.▷For objects with corners and sharp edges.▷For objects with fine surfaces or struc‐
tures, for example fences.▷For objects with porous surfaces.
Low objects already indicated, such as kerbs,
may enter the sensors' blind areas before or
after a continuous tone is given.
False alarms
Under the following conditions, PDC can issue
a warning although there is no obstacle in the
detection range:
▷In heavy rain.▷If the sensors are very dirty or covered with
ice.▷If the sensors are covered with snow.▷On rough road surfaces.▷On uneven ground, for example speed
bumps.▷In large, rectangular buildings with smooth
walls, for example underground car parks.▷In car washes.▷Due to dense exhaust gas.▷Due to other ultrasonic sources, for exam‐
ple sweeping machines, steam-jet cleaners
or neon lights.
The functional disruption is reported by an
alternating continuous tone between the
front and rear loudspeakers. 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.
Surround view Principle
