Objects in the driver's foot we ll may impede
pedal tr avel or block a depressed pedal.
This jeopardises the operating and road
saf ety of theve hicle. #
Stow all objects in theve hicle securely
so that they cannot getinto the driver's

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 theve
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
In cer tain cases, it may be requiredtostore 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 adout 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 36
