Some control units are
requ ired forth e safe
operation of your vehicle, some assist you when
driving, such as driver assis tance sy stems, while
ot hers enable con venience or inf otainment func‐
tions.
The following pr ovides you with general informa‐
tion rega rding data processing in theve hicle.
Ad ditional information rega rding exact ly which

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 online 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

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‐
