In addition to pr ov iding th e actual control unit
function, th is data assists th e manufacturer in
de te cting and re ctifying malfunctions and opti‐
mizing ve hicle functions. The majority of th is
data is te mp orary and is only processed in th e
ve hicle itself. Only a small portion of th e data is
st ored in th e ev ent or malfunction memor y.
When yo ur ve hicle is serviced, te ch nical da ta
from th e ve hicle can be re ad out by service net‐
wo rk emplo ye es or th ird parties. Services
include re pair services, maintenance processes, wa rr anty eve nts and qu ality assurance meas‐
ures, fo r ex ample. The re ad out is per fo rm ed via
th e legally prescribed port fo r OBD ("on-board
diagnostics") in th e ve hicle. The re spective
service network locations or th ird parties col‐
lect, process and use th e data. They document
te ch nical st atuses of th e ve hicle, assist in fi nd ‐
i
ng malfunctions and impr ov ing qu ality and are
transmit te d to th e manufacturer, if necessar y.
Fu rt hermore, th e manufacturer is subject to
product liability. Fo r th is, th e manufacturer
re qu ires te ch nical da ta from ve hicles.
Malfunction memories in th e ve hicle can be
re set by a service outlet as part of re pair or
maintenance wo rk .
They can enter data into th e ve hicle's con ve ni‐
ence and inf ot ainment functions th emselves as

Pa rk ing Assist PA RKTRONI C function whic h
wa rn s th e driver about obs ta cles at th e side of
th e ve hicle. A wa rn ing is issued when obs ta cles
are de te cted between th e front and re ar de te c‐

th e sensors in th e front or re ar bumper must
de te ct th e object while yo u are drivin g past it. During th e parking procedure or maneuvering,
objects are de te cted as th e ve hicle drives past.
If yo u st eer in th e direction of a de te cted obs ta ‐
cle and th ere is a ri sk of a lateral collision, a
wa rn ing is issued. The lateral segments light up
