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, forex ample, repair services,
maintenance processes, warranty claims and
qu ality assurance measures. 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 vehicle con venience 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. a smartphone, USB flash
drive or MP3 pla yer). If this data is stored in the
ve hicle, you can dele teit at any time. This data
is sent tothird parties only at your requ est, par‐
ticular lywhen you use online services in accord‐
ance with the settings that you ha veselected.
Yo u can store or change con venience settings/
individualisations in theve hicle at any time. 32
General no tes

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 customisations 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‐
tai n information is simultaneously trans ferred to
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.
Manu factu rer's se rvices
Re garding online services of the manufacturer,
th e individual functions are described bythe
manufacturer in a suita ble place (e.g. Owner's
Manual, website of the manufacturer) along with
th ere leva nt da taprotection information. Per‐ sonal data may be used
forth e pr ovision of
online services. Data is exchanged via a secure
connection, e.g. the manufacturer's designated
IT sy stems. Personal data is collected, pro‐
cessed and used via the pr ovision of services
exc lusively on the basis of legal permissions or
with prior consent.
The services and functions (sometimes subject
to afe e) can usually be activated or deactivated.
In some cases, this also applies tothe entire
ve hicle's data connection. This excludes, in par‐
ticular, legally prescribed functions and services.
Third pa rty services
If it is possible touse online services from other
pr ov iders, these services are there sponsibility
of the pr ovider in question and subject tothat
pr ov ider's data pr otection conditions and terms
of use. The manufacturer has no influence on
th e conte ntexc hanged.
Fo rth is reason, please ask the service pr ovider
fo r information about the type, extent and pur‐
pose of the collection and use of personal data
when services are pr ovided bythird parties. General no

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 is de term ined by
th e se verity of the impact de tected and the type
of accident anticipated:
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.
Fa ctors whi chcan only be seen and measu red
af te r a collision has occur red do not play a deci‐
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, 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
ot her:
R Seat belt tensioner: frontal impact, rear
impact, side impact, rollo ver
R Driver's airbag, front passenger airbag: fron‐
talimpact
R Knee airbag: frontal impact
R Side airbag: side impact
R Head airbag: side impact, rollo ver,frontal
impact
The front passenger airbag can only be depl oyed
in an accident if thePA SSENGER AIR BAG OFF

When
the ignition is switched on, a self-test is
per form ed during which the two PASSENGER
AIR BAG ON and OFF indicator lamps light up
simul taneously.
The status of the front passenger airbag is dis‐
pla yed via thePA SSENGER AIR BAG indicator
lamps af terth e self-tes t:
R ON is lit: the front passenger airbag may
deploy during an accident.
The indicator lamp goes out af ter appro x‐
ima tely 60 seconds.
R ON and OFF are not lit: the front passenger
airbag may deploy during an accident.
R OFF is lit: the front passenger airbag is disa‐
bled. It will then not be deplo yed in theev ent
of an accident.
If th ePA SSENGER AIR BAG ON indicator lamp is
off, on lythePA SSENGER AIR BAG OFF indicator

and the6 restra int sy stem warning lamp
light up simultaneousl y,the front passenger seat
may not be used. Also in this case, do not fit a
