In
general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating status of sy stem components (e.g.
fi ll le vels, battery status, tyre pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, longitudinal accel‐
eration, lateral acceleration, display of fas‐
te ned seat belts)
R malfunctions or faults in impor tant sy stem
components (e.g. lights, brakes)
R information on events leading tovehicle
damage
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
R ambient conditions (e.g. temp erature, rain
sensor)
In addition toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying faults and optimising
ve hicle functions. The majority of this data is te
mp orary and is only processed in theve hicle
itself. Only a small portion of the data is stored
in theeve nt or fault memor y.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty claims and quality assur‐
ance measures, forex ample. The read out is per‐
fo rm ed via the legally prescribed port forthe
diagnostics connection in theve hicle. The
re spective service network locations or third
parties collect, process and use the data. They
document tech nical statuses of theve hicle,
assist in finding faults and impr oving quality and
are transmitted tothe manufacturer, if neces‐
sar y.Fu rthermore, the manufacturer is subject
to product liability. Forth is, the manufacturer
requ irestech nical da tafrom vehicles.
Fa ult memories in theve hicle can be reset by a
service outlet as part of repair or maintenance
wo rk. Depending on
the selected equipment, you can
import data into theve hicle's comfort and info‐
ta inment functions yourself.
This includes, forex ample:
R multimedia data such as music, films or pho‐
to sfo r playback in an integrated multimedia
sy stem
R address book data for use in connection with
an integrated hands-free sy stem or an inte‐
grated navigation sy stem
R entered navigation destinations
R data about the use of Internet services
This data can be sa ved locally in theve hicle or it
is located on a device which you ha veconnected
to theve hicle (e.g. smartphone, USB flash drive
or MP3 pla yer). If this data is stored in theve hi‐
cle, you can dele teit at any time. This data is
sent tothird parties only at your requ est, partic‐
ular lywhen you use online services in accord‐
ance with the settings that you ha veselected.
Yo u can store or change con venience settings/
individualisations in theve hicle at any time. General no

Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving.

doing so, you will make use of the engine's brak‐
ing ef fect. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed limits, e.g. in built-up
areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode. The
variable limiter is operated using the cor re‐
sponding steering wheel buttons. You can store
any speed abo ve20 km/h up tothe maximum
speed or up tothe set winter tyre limit. You can
also per form settings while theve hicle is station‐
ary if theve hicle has been star ted.
If yo ufa ilto adapt your driving style, the limiter
can neither reduce therisk of an accident nor
ov erride the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. The
limiter is only an aid. You are responsible for
maintaining a safe dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.

nction of Active Parking Assist
Ac tive Parking Assist is an elect ronic pa rking
assis tance sy stem which uses ultrasound and is
automatically activated during forw ard tra vel.
The sy stem is operational at speeds of up to
appr oximately 35 km/h. When all the conditions
are fulfilled, thec symbol appears in themultifunction display and
the sy stem automati‐
cally sear ches for and measu res parking spaces
on bo thsides of theve hicle parallel and perpen‐
dicular tothe direction of tra vel. If Active Parking
Assist is activated, suitable parking spaces are
displa yed in the multimedia sy stem. The ë
symbol appears in the multifunction displa y.The

free parking spaces are loca ted.
The parking space and, if necessar y,the parking
direction can be selected as desired. Active
Pa rking Assist calculates a suitable vehicle path
and assists you in parking and exiting the park‐
ing space.
Ac tive Parking Assist changes gear, accelerates,
brakes and steers theve hicle.
Ac tive Parking Assist is only an aid. It is not a
substitute foryo ur attention tothe sur roundings.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that no
persons, animals or objects etc. are in the
manoeuvring range. Ac
tive Parking Assist is cancelled if, among

when the parking space is being measured.
These are also not take n into account when the
parking manoeuvre is calculated, e.g. overhang‐
