driving (driver assis
tance sy stems). In addition,
yo ur vehicle pr ovides com fort and enter tainment
functions, which are also made possible byelec‐
tronic control units.
Elect ronic control units contain da tamemories
which can temp 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 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 Gene

WARNING Risk of inju rydue tomalfunc‐

If th ere stra int sy stem is malfunctioning,

there stra int sy stem works is de term ined by

of accident anticipated:
R Frontal impact
R Rear impact
R Side impact
R Onlyfor cer tain countries: rollo ver
The activation thre sholds forth e components of
th ere stra int sy stem are de term ined based on
th eev aluation of the sensor values measured at
va rious points in theve hicle. This process is pre-
em ptive in nature. The triggering/deployment of
th e components of there stra int sy stem must ta
ke place in good time at thest art of the colli‐
sion.

sive role in the deployment of an airbag. Nordo
th ey prov ide an indication of airbag deployment.
The vehicle may be deformed significantly with‐
out an airbag being deplo yed. This is the case if
only parts which are relatively easily deformed
are af fected and thera te ofvehicle deceleration
is not high. Con versely, an airbag may be
deplo yedev en though theve hicle suf fers only
minor deformation. If very rigid vehicle parts
such as longitudinal members are hit, forex am‐
ple, this may result in suf ficiently high le vels of

R There are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks.
R There are no accessory parts, such as mobile
navigation devices, mobile phones or cup
holders, attached totheve hicle within the
deployment area of an airbag, e.g. on the
cockpit, on the door, on the side window or
on the side wall trim. In addition, no connecting cables,
tensioning
st ra ps or retaining stra ps must be routed or
attached totheve hicle within the deploy‐
ment area of an airbag. Alw ays comply with
th e accessory manufacturer's ins tallation
instructions and, in particular, the no tes on
suitable places for ins tallation.
R There are no heavy, sharp-edged or fragile
objects in the poc kets of your clo thing. Store
such objects in a suitable place. Limited pr

WARNING Risk of inju rydue tomodifi‐
cations tothe airbag co ver
If yo u modify the co ver of an airbag or af fix
objects such as sticke rs to it,the airbag may
no longer function cor rectly. #
Never modify the co ver of an airbag and

by the AIRB AGsymbol (/ page41). &
WARNING Risk of inju ryor death due to
th e use of unsuitable seat co vers
Uns uitable seat co vers can obstruct or pre‐
ve nt the deployment of the airbags integra‐
te d into the seats.
Consequentl y,the airbags cann otprotect
ve hicle occupants as they are designed to
do. In addition, the operation of the auto‐
matic front passenger airbag shutoff could
be restricted. #
