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‐
