wi th hot parts of theex haust sy stem. #
When driving on unpa vedro ads or off-

TEDama getotheve hicle In
thefo llowing situations, in particular, there
is a risk of damage totheve hicle:
R theve hicle becomes grounded, e.g. on a
high kerb or an unpa vedro ad R
theve hicle is driven toofast over an
obs tacle, e.g. a kerb, speed bump or 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
tyres could be damaged without the damage
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.
If th e underbody panelling is damaged, flam‐
mable materials such as lea ves, grass or
twigs can collect between the underbody and
th e underbody panelling. These materials
may ignite if they come into contact wi thhot
parts on theex haust sy stem. #
Have theve hicle checked and repaired
immediately at a qualified specialist
wo rkshop.

If driving saf ety is impaired while con‐
tinuing your journe y,pull over and stop

DANG ER Risk of fata l injury bytouching
damaged high-voltage co mponents
Ve hicles with a 48 V on-board electrical sys‐
te m contain individual high-voltage compo‐
nents. These high-voltage components are
under high voltage.
If yo u modify co mponent parts of these high-
vo ltage components or touch damaged com‐
ponent parts, you may be electrocuted.
High voltage components may be damaged
in an accident, although the damage may not
be visible. #

ch nical information about theve hicle's operat‐
ing state, component loads, main tenance
re qu irements and tech nical events or faults.
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, tyre 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 faults and optimising
ve hicle functions. The majority of this data is
te mp orary and is only processed in theve hicle
itself. Only a small portion of the data is stored
in theeve nt or fault 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 faults and impr oving quality and
are transmitted tothe manufacturer, if neces‐
sar y.Fu rthermore, the manufacturer is subject
to product liability. Forth is, the manufacturer
requ irestech 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.
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‐
