Electronic control units con tain data memo ries
which can permanently or temp orarily store tech‐
nical information on theve hicle's operating state,
component stre ss, service requirements as well
as tech nical events and malfunctions.
This information general lydocuments thest ate of
a component part, a module, a sy stem or of the
environment such as:
R operating statuses of sy stem components
(e.g. fluid le vels, battery status, tire pressure)
R status messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, deceleration, lateral
acceleration, display of thefast ened seat
belts)
R malfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
R information on events in which theve hicle is
damaged
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐

R ambient conditions (e.g. temp erature, rain

In addition tothe pr ovision of control unit func‐
tions, this data ser vesto recognize and rectify
malfunctions as well as tooptimize vehicle func‐

vo latile and is only processed in theve hicle itself.
Only a small proportion of the data is stored in

When you use services, thete ch nical da tafrom
th eve hicle can be read out byservice network
emplo yees (e.g. workshops, manufacturers) or
th ird parties (e.g. breakdown services). Services
include repair services, maintenance processes, wa

which is requ ired bylaw. The respective service
network locations or third parties collect, process

Recorders USA onl

This vehicle is equipped with an event da ta
re corder (EDR). The main pu rpose of an EDR is to
re cord, in cer tain crash or near crash-like situa‐
tions, su chas an air bag deployment or hitting a
ro ad obs tacle, da tathat will assist in unde rsta nd‐
ing how a vehicle's sy stems per form ed. The EDR
is designed torecord da tarelated tovehicle
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 such
da ta as:
R How various sy stems in your vehicle were
operating;
R Whe ther or not the driver and passenger
saf ety 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 ave ling.
This data can help pr ovide a better under standing
of the circums tances in whi chcrashes and inju‐
ri es occur. NOTE: EDR data are recorded by your
ve hicle only if a non-trivial crash situation occurs;
no data are recorded bythe EDR under normal
driving conditions and no personal data (e.g.
name, gende r,age and crash location) are recor‐
ded. Ho wever,ot her parties such as law enforce‐
ment could combine the EDR data with the type
of personally 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 byan EDR, and spe‐
cial equipment is requ ired. In addition totheve hi‐
cle manufacturer, other parties that ha vethe spe‐
cial equipment, such as law enforcement, can
re ad the information byaccessing theve hicle or
