QR code
forre scue card
QR codes are attached in the fuel filler flap and
on the opposite side on the B-pillar. In theeve nt
of an accident, rescue services can use the QR
code toquickly find the appropriate rescue card
fo ryo ur vehicle. The cur rent rescue card con‐
ta ins the most impor tant information about your
ve hicle in a compact form , e.g. thero uting of the
electric lines.
Fu rther information can be obtained at https://
www.mercedes-benz.de/qr-code. Data
storage Data processing in
theve hicle Electronic control units
Electronic control units are
fitted in your vehicle.
Control units process data which, forex ample,
th ey recei vefrom vehicle sensors, generate
th emselves or exch ange between themselves.
Some control units are requ ired forth e safe
operation of your vehicle, some assist you when
driving, such as driver assis tance sy stems, while ot
hers enable con venience or inf otainment func‐
tions.
The following pr ovides you with general informa‐
tion rega rding data processing in theve hicle.
Ad ditional information rega rding exact ly which
da ta inyour vehicle are collected, sa ved and
transmit tedto third parties and for what pur‐
pose, can be found in the information directly
re lated tothe functional characteristics in ques‐
tion in their respective operating instructions.
This information is also available online and,
depending on theve hicle equipment, digitally.
Pe rsonal data
Every vehicle is identified bya unique vehicle
identification number. Depending on the coun‐
tr y, this vehicle identification number can be
used by,fo rex ample, go vernmental auth orities
to determ ine the identity of theow ner. The reare
ot her possibilities touse data collec ted from the
ve hicle toidentify theow ner or driver, su chas
th e licence plate number.
Therefore, data generated or processed bycon‐
trol units may be attributable toa person or,
under cer tain conditions, become att ributable toa person. Depending on which
vehicle data are
av ailable, it may be possible tomake inferences
about, forex ample, your driving behaviour, your
location, your route or your use pat tern s.
Legal requirements rega rding the disclosure
of data
If legally requ ired todo so, manufacturers are, in
individual cases, legally obliged toprov ide gov‐
ernmental entities, upon request and tothe
ex tent requ ired, data stored bythe manufac‐
turer. Forex ample, this may be the case during
th e in vestigation of a criminal of fence.
Go vernmental entities are themselves, in individ‐
ual cases and within the applicable legal frame‐
wo rk, authorised toread out data from theve hi‐
cle. In the case of an accident, information that
can help with an in vestigation can, therefore, be
ta ke n from the airbag control unit, forex ample.
Operational data in theve hicle
This is data rega rding the operation of theve hi‐
cle, which ha vebeen processed bycontrol units.
This includes thefo llowing data, forex ample:
R vehicle status information such as the speed,
longitudinal acceleration, lateral accelera‐ 36
General no tes

tion, number of wheel
revo lutions or thefa s‐
te ned seat belts displ ay
R ambient conditions, such as temp erature,
ra in sensor or dis tance sensor
General ly,th e use of these data is temp orar y;
th ey will not be stored be yond the period of
operation and will only be processed within the
ve hicle itself. Control units of ten contain da ta
memories forve hicle keys,fo rex ample. Their
use permits thete mp orary or permanent docu‐
mentation of tech nical information about the
ve hicle's operating state, component loads,
main tenance requ irements and tech nical events
or faults.
Depending on theve hicle equipment, thefo llow‐
ing data are stored:
R operating status of sy stem components,
such as fill le vels, tyre pressure or battery
st atus
R malfunctions or faults in impor tant sy stem
components, such as lights or brakes
R system reactions in special driving situations,
such as airbag deployment or the inter ven‐
tion of stability control sy stems R
information on events leading tovehicle
damage
In cer tain cases, it may be requiredtostore data
th at wo uld ha veotherwise been used only tem‐
poraril y.This may be the case if theve hicle has
de tected a malfunction, forex ample.
If yo u use services, such as repair services and
maintenance work,st ored operational data as
we ll as theve hicle identification number can be
re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manufacturers or third parties, such as
breakdown services. The same is true in the
case of warranty claims and quality assurance
measures.
In general, there adout is per form ed via the
legally prescribed port forth e diagnostics con‐
nection in theve hicle. The operational data that
are read out document tech nical states of the
ve hicle or of individual components and assist in
th e diagnosis of malfunctions, compliance with
wa rranty obligations and quality impr ovement.
To that end, these data, in particular information
about component loads, tech nical events, mal‐ functions and
other faults may be transmitted
along with theve hicle identification number to
th e manufacturer. Furthermore, the manufac‐
turer is subject toproduct liability. Forth is rea‐
son the manufacturer also uses operational data
from theve hicle, forex ample, forre calls. These
da ta can also be used toexamine the cus tom‐
er's warranty and guarantee claims.
Fa ult memories in theve hicle can be reset by a
service outlet or at your requ est as part of repair
or maintenance work.
Con venience and inf otainment functions
Yo u can store con venience settings and individ‐
ual settings in theve hicle and change or reset
th em at any time.
Depending on theve hicle equipment, this
includes thefo llowing settings, forex ample:
R seat and steering wheel positions
R suspension and climate control settings
R individual settings, such as interior lighting
Depending on the selected equipment, you can

WARNING Risk of inju rydue tomalfunc‐
tions in there stra int sy stem
Components in there stra int sy stem may be
activated unintentionally or not deploy as
intended in an accident. #
Have there stra int sy stem checked and
re paired immediately at a qualified spe‐
cialist workshop. Fu
nction of there stra int sy stem in an acci‐
dent How
there stra int sy stem works depends on the
se verity of the impact de tected and the apparent
type of acciden t:
R Frontal impact
R Rear impact
R Side impact
R Rollover
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.

af te r a collision has occur red cann otplay a deci‐
sive role in airbag deployment. Nor do they pro‐
vide 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, this may
re sult in suf ficiently high le vels of vehicle decel‐
eration.
Depending on the de tected deployment situa‐
tion, the components of there stra int sy stem can
be activated or deplo yed independently of each
