The
following pr ovides you with general informa‐
tion rega rding data processing in theve hicle.
Ad ditional information rega rding exact ly which
da ta inyour vehicle are collected, sa ved and
transmit tedto third parties and for what pur‐
pose, can be found in the information directly
re lated tothe functional characteristics in ques‐
tion in their respective operating instructions.
This information is also available on line and,
depending on theve hicle equipment, digitally.
Pe rsonal data
Every vehicle is identified bya unique vehicle
identification number. Depending on the coun‐
tr y, this vehicle identification number can be
used by,fo rex ample, go vernmental auth orities
to determ ine the identity of theow ner. The reare
ot her possibilities touse data collec ted from the
ve hicle toidentify theow ner or driver, su chas
th e licence plate number.
Therefore, data generated or processed bycon‐
trol units may be attributable toa person or,
under cer tain conditions, become att ributable to
a person. Depending on which vehicle data are
av ailable, it may be possible tomake inferences about,
forex ample, your driving behaviour, your
location, your route or your use pat tern s.
Legal requirements rega rding the disclosure
of data
If legally requ ired todo so, manufacturers are, in
individual cases, legally obliged toprov ide gov‐
ernmental entities, upon request and tothe
ex tent requ ired, data stored bythe manufac‐
turer. Forex ample, this may be the case during
th e in vestigation of a criminal of fence.
Go vernmental entities are themselves, in individ‐
ual cases and within the applicable legal frame‐
wo rk, authorised toread out data from theve hi‐
cle. In the case of an accident, information that
can help with an in vestigation can, therefore, be
ta ke n from the airbag control unit, forex ample.
Operational data in theve hicle
This is data rega rding the operation of theve hi‐
cle, which ha vebeen processed bycontrol units.
This includes thefo llowing data, forex ample:
R vehicle status information such as the speed,
longitudinal acceleration, lateral accelera‐
tion, number of wheel revo lutions or thefa s‐
te ned seat belts displ ay R
ambient conditions, such as temp erature,
ra in sensor or dis tance sensor
General ly,th e use of these data is temp orar y;
th ey will not be stored be yond the period of
operation and will only be processed within the
ve hicle itself. Control units of ten contain da ta
memories forve hicle keys,fo rex ample. Their
use permits thete mp orary or permanent docu‐
mentation of tech nical information about the
ve hicle's operating state, component loads,
main tenance requ irements and tech nical events
or faults.
Depending on theve hicle equipment, thefo llow‐
ing data are stored:
R operating status of sy stem components,
such as fill le vels, tyre pressure or battery
st atus
R malfunctions or faults in impor tant sy stem
components, such as lights or brakes
R system reactions in special driving situations,
such as airbag deployment or the inter ven‐
tion of stability control sy stems
R information on events leading tovehicle
damage General no
tes35

In cer
tain cases, it may be requ ired tostore data
th at wo uld ha veotherwise been used only tem‐
porarily. This may be the case if theve hicle has
de tected a malfunction, forex ample.
If yo u use services, such as repair services and
maintenance work,st ored operational data as
we ll as theve hicle identification number can be
re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manufacturers or third parties, such as
breakdown services. The same is true in the
case of warranty claims and quality assurance
measures.
In general, there ad out is per form ed via the
legally prescribed port forth e diagnostics con‐
nection in theve hicle. The operational data that
are read out document tech nical states of the
ve hicle or of individual components and assist in
th e diagnosis of malfunctions, compliance with
wa rranty obligations and quality impr ovement.
To that end, these data, in particular information
about component loads, tech nical events, mal‐
functions and other faults may be transmit ted
along with theve hicle identification number to
th e manufacturer. Furthermore, the manufac‐ turer is subject
toproduct liability. Forth is rea‐
son the manufacturer also uses operational data
from theve hicle, forex ample, forre calls. These
da ta can also be used toexamine the cus tom‐
er's warranty and guarantee claims.
Fa ult memories in theve hicle can be reset by a
service outlet or at your requ est as part of repair
or maintenance work.
Con venience and inf otainment functions
Yo u can store con venience settings and individ‐
ual settings in theve hicle and change or reset
th em at any time.
Depending on theve hicle equipment, this
includes thefo llowing settings, forex ample:
R seat and steering wheel positions
R suspension and climate control settings
R individual settings, such as interior lighting
Depending on the selected equipment, you can
import data into vehicle inf otainment functions
yo urself. Depending on
theve hicle equipment, this
includes thefo llowing data, 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
These data for con venience and inf otainment
functions may be sa ved locally in theve hicle or
th ey may be located on a device which you ha ve
connected totheve hicle, such as a smartphone,
USB flash drive or MP3 pla yer.If yo u ha ve
entered these data yourself, you can dele tethem
at any time.
This data is transmit ted from theve hicle tothird
parties only at your requ est. This applies, in par‐
ticular, when you use online services in accord‐
ance with the settings that you ha veselected. 36
