Fu rther information can be obtained at http://

storage Electronic control units
Elect
ronic control units are ins talled in your vehi‐
cle. Some of these are necessary forth e safe
operation of your vehicle, while some assist you
when driving (driver assis tance sy stems). In
addition, your vehicle pr ovides com fort and
enter tainment functions, which are also made
possible byelectronic control units.
Elect ronic control units contain da tamemories
which cantemp orarily or permanently store
te ch nical information about theve hicle's operat‐
ing state, component loads, main tenance
re qu irements and tech nical events or malfunc‐
tions. In
general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating status of sy stem components (e.g.
fi ll le vels, battery status, tire pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, longitudinal accel‐
eration, lateral acceleration, display of fas‐
te ned seat belts)
R malfunctions or faults in impor tant sy stem
components (e.g. lights, brakes)
R information on events leading tovehicle
damage
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
R ambient conditions (e.g. temp erature, rain
sensor)
In addition toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this data is
temp orary and is only processed in the
ve hicle itself. Only a small portion of the data is
st ored in theeve nt or malfunction memor y.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty claims and quality assur‐
ance measures, forex ample. The read out is per‐
fo rm ed via the legally prescribed port forthe
diagnostics connection in theve hicle. The
re spective service network locations or third
parties collect, process and use the data. They
document tech nical statuses of theve hicle,
assist in finding malfunctions and impr oving
qu ality and are transmit tedto the manufacturer,
if necessar y.Fu rthermore, the manufacturer is
subject toproduct liability. Forth is, the manu‐
fa cturer requirestech nical da tafrom vehicles.
Fa ult memories in theve hicle can be reset by a
service outlet as part of repair or maintenance
wo rk. 26

sonal data may be used
forth e pr ovision of
online services. Data is exch anged via a secure
connection, e.g. the manufacturer's designated
IT sy stems. Personal data is collected, pro‐
cessed and used via the pr ovision of services
exc lusively on the basis of legal permissions or
with prior consent.
The services and functions (sometimes subject
to afe e) can usually be activated or deactivated.
In some cases, this also applies tothe entire
ve hicle's data connection. This excludes, in par‐

If it is possible touse online services from other
pr ov iders, these services are subject tothe data

Please inquire, therefore, about the type, scope
and purpose of the collection and use of per‐

If
th eve hicle is equipped with COMAND or

ation, the use of theve hicle in cer tain situations,

Te rm s and Conditions. Event data
recorders USA onl
y:
This vehicle is equipped with an event data
re corder (EDR). The main pu rpose of an EDR is
to record, in cer tain crash or near crash-like sit‐
uations, such as an airbag deployment or hitting
a ro ad obs tacle, da tathat will assist in under‐
st anding how a vehicle's sy stems per form ed.
The EDR is designed torecord da tarelated to
ve hicle dynamics and saf ety sy stems for a short
period of time, typically 30 seconds or less. The EDR in
this vehicle is designed torecord
su ch data as:
R How various sy stems in your vehicle were
operating
R Whe ther or not the driver and front
passenger seat belts werebuckled/fas tened
R How far (if at all) the driver was depressing
th e accelera tor and/or brake pedal and
R How fasttheve hicle was tr aveling
This data can help pr ovide a better under stand‐
ing of the circums tances in which accidents and
inju ries occur. NOTE: EDR data is recorded by
yo ur vehicle only if a non-trivial crash situation
occurs; no data is recorded bythe EDR under
normal driving conditions and no personal data
(e.g. name, gende r,age and accident location) is
re corded. Ho wever,ot her parties, such as law
enforcement, could combine EDR data with the
type of pe rsonally identifying data routinely
acquired during a crash in vestigation.
Ac cess totheve hicle and/or the EDR is needed
to read data that is recorded bythe EDR, and
