TEDama getotheve hicle In
thefo llowing situations, in particular, there
is a risk of damage totheve hicle:
R The vehicle becomes grounded, e.g. on a
high curb or an unpa vedro ad
R The vehicle is driven toofast over an
obs tacle, e.g. a curb, speed bu mpor pot‐
hole
R A heavy object strike sth e underbody or
ch assis components
In situations such as this, the body, the
underbody, chassis components, wheels or

being visible. Components damaged in this
wa y can unexpec tedly fail or, in the case of
an accident, may not absorb the loads that
arise as intended. 22

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

Depending on
the selected equipment, you can
import data into theve hicle's comfort and info‐
ta inment functions yourself.
This includes, forex ample:
R multimedia data such as music, films or pho‐
to sfo r playback in an integrated multimedia
sy stem
R address book data for use in connection with
an integrated hands-free sy stem or an inte‐
grated navigation sy stem
R entered navigation destinations
R data about the use of Internet services
This data can be sa ved locally in theve hicle or it
is located on a device which you ha veconnected
to theve hicle (e.g. smartphone, USB flash drive
or MP3 pla yer). If this data is stored in theve hi‐
cle, you can dele teit at any time. This data is
sent tothird parties only at your requ est, partic‐
ular lywhen you use online services in accord‐
ance with the settings that you ha veselected.
Yo u can store or change con venience settings/
individualization in theve hicle at any time. Depending on
the equipment, this includes, for
ex ample:
R settings forth e seat and steering wheel posi‐
tions
R suspension and climate control settings
R customizations such as interior lighting
If yo ur vehicle is accordingly equipped, you can
connect your smartphone or ano ther mobile end
device totheve hicle. You can cont rolth is by
means of the control elements integrated in the
ve hicle. Images and audio from the smartphone
can be output via the multimedia sy stem. Cer‐
ta in information is simultaneously transfer redto
yo ur smartphone.
Depending on the type of integration, this can
include:
R general vehicle data
R position data
This allo wsyouto use selected apps on your
smartphone, such as navigation or music play‐
bac k.There is no fur ther interaction between the
smartphone and theve hicle; in particular, vehi‐
cle data is not directly accessible. Which type of fur
ther data processing occurs is de term ined by
th e pr ovider of the specific app used. Which set‐
tings you can make, if an y,depends on the spe‐
cific app and the operating sy stem of your
smartphone. Online services
Wire
less network connection
If yo ur vehicle has a wireless network connec‐
tion, it enables data tobe exc hanged between
yo ur vehicle and additional sy stems. The wire‐
less network connection is enabled via theve hi‐
cle's transmission and reception unit or via con‐
nected mobile end devices (e.g. sma rtphones).
Online functions can be used via the wireless
network connection. This includes online serv‐
ices and applications/apps pr ovided bythe man‐
ufacturer or other pr oviders.
