rally, these are volatile data and will not be
st ored be yond the period of operation but will
only be processed within theve hicle itself. Con‐

or permanent documentation of tech nical infor‐
mation about theve hicle's operating state, com‐
ponent loads, main tenance requirements and
te ch nical events or faults.
Depending on thete ch nical equipment, thefo l‐
lowing data are stored:
R operating status of sy stem components, such
as fill le vels, tyre pressure or battery status
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 vention

damaged
In cer tain cases, it may be requ ired tostore data

If yo u use services, such as repair services and
maintenance work,st ored operational data as

service network emplo yees, such as workshops
and manufacturers or third parties, such as
breakdown services. The same is true in the case
of wa rranty claims and quality assurance meas‐

In general, there adout is per form ed via the
legally prescribed port forth e diagnostics con‐

are read out document tech nical states of the

th at end, these data, in particular information
about component loads, tech nical events, mal‐
functions and other faults may be transmitted
along with theve hicle identification number to
th e manufacturer. In addition, the manufacturer is
subject toproduct liability. Forth is reason, the
manufacturer also uses operational data from the

also be used toexamine the cus tomer's warranty
and guarantee claims. Fa

Con venience and inf otainment functions
Yo u can store con venience settings and individual

at any time.
Depending on theve hicle equipment, this
