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 or third parties. Services
include repair services, maintenance processes,
wa rranty events and quality assurance meas‐
ures, forex ample. The read out is per form ed via
th e legally prescribed port for OBD ("on-board diagnostics") in
theve hicle. The respective
service network locations or third parties col‐
lect, process and use the data. They document
te ch nical statuses of theve hicle, assist in find‐
ing malfunctions and impr oving quality and are
transmitted tothe manufacturer, if necessar y.

and their setting checked at a qualified spe‐
cialist workshop.
Do not use the 360° Camera under such circum‐
st ances. You could otherwise injure others or
collide with objects when parking theve hicle.
On vehicles with height-adjus table suspension or
if th eve hicle is car rying a heavy load, leaving the
st andard height can result in inaccuracies in the
guide lines and in the display of thege nerated
ima ges, depending on tech nical conditions.
The field of vision and other functions of the
