card contains, in compact

Fu rther information can be found at http://

storage Electronic control units
Electronic control units are ins
talled in your vehi‐
cle. Some of these are necessary forth e safe
operation of your vehicle, while some assist you
when driving (driver assis tance sy stems). In addi‐
tion, your vehicle pr ovides com fort and enter tain‐
ment functions, which are also made possible by
electronic cont rol units.
The elect ronic control units contain da tamemo‐
ri es which can temp orarily or permanently store
te ch nical information about theve hicle's operat‐
ing state, component loads, main tenance requ ire‐
ments and tech nical events or malfunctions.
In general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating states of sy stem components (e.g.
fl uid le vels, battery status, tire pressure)
R status messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, deceleration, lateral
acceleration, display of thefast ened seat
belts)
R malfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
R information on events leading tovehicle dam‐
age
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 cont rol unit
function, this data assists the manufacturer in
de tecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this data
is temp orary and is only processed in theve hicle
itself. Only a small portion of the data is stored in
th eeve nt or malfunction memo ry.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees (e.g. workshops, manufacturers)
or third parties (e.g. breakdown services). Serv‐ ices include
repair services, maintenance pro‐
cesses, warranty claims and quality assurance
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 par‐
ties collect, process and use this data. They
document tech nical statuses of theve hicle,
assist in finding malfunctions and impr oving qual‐
ity and are transmitted tothe manufacturer, if
necessar y.Fu rthermore, the manufacturer is sub‐
ject toproduct liability. Forth is, the manufacturer
re qu ires tech nical da tafrom vehicles.
Malfunction memories in theve hicle can be reset
by a service outlet as part of repair or mainte‐
nance work.
Depending on the selected equipment, you can
import data into vehicle con venience 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, particu‐
lar lywhen you use online services in accordance
with the settings that you ha veselected.
Yo u can store or change con venience settings/
individualization in theve hicle at any time.
Depending on the equipment, this includes, for
ex ample:
R seat and steering wheel position settings
R suspension and climate cont rol settings
R Individualization such as interior lighting
If yo ur vehicle is accordingly equipped, you can
connect your smartphone or ano ther mobile end
device totheve hicle. You can control this by
means of the cont rol elements integrated in the
ve hicle. Images and audio from the smartphone
can be output via the multimedia sy stem. Cer tain General no
