Ingeneral, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
Roperating statuses of sy stem components
(e.g. fluid leve ls, battery status, tire pressure)
Rstatus messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, decele ration, lat‐
eral acceleration, display of thefast ened seat
belts)
Rmalfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
Rinformation on vehicle damage events
Rsystem reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
Rambient 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 theev ent or malfunction memor y.
When service workis done on your vehicle, the
te ch nical da tafrom theve hicle can be read out
by service network staff (e.g. workshops, manu‐
fa cturer) or third parties (e.g. breakdown serv‐
ices). Services include repair services, mainte‐
nance processes, warranty events a
nd
quality
assurance measures, forex ample. The read out
is per form ed via the legally prescribed port for
th e 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 transmitted tothe manufacturer,
if necessar y.Fu rthermore, the manufacturer is
subject toproduct liability. Forth is, the manu‐
fa cturer requirestech nical da tafrom vehicles.
Malfunction memories in theve hicle can be
re set bya service outlet as part of repair or
maintenance work.
They can enter data into theve hicle's comfort
and inf otainment functions themselves as part
of the selected equipment. These include:
Rmultimedia data such as music,
films or pho‐
to sfo r playba ckin an integrated multimedia
sy stem
Raddress book data for use in connection with
an integrated hands-free sy stem or an inte‐
grated navigation sy stem
Rentered navigation destinations
Rdata 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 c
an dele
teit at any time. This data can
only be transmitte dto third parties upon your
re qu est with particular rega rd tothe scope of
use of online services according toyour selected
settings.
Yo u can store or change con venience settings/
individualization in theve hicle at any time.
Depending on the equipment, this includes, for

Restra int sy stem functionality
When the ignition is switched on, a self-test is
per form ed, during which the6 restra int sys‐
te m wa rning lamp lights up. It goes out no later
th an a few seconds af terth eve hicle is star ted.
The components of there stra int sy stem are then
functional.
Malfunctioning restra int sy stem
A malfunction has occur red in there stra int sys‐
te m if:
RThe 6 restra int sy stem warning lamp
does not light up when the ignition is
switched on.
RThe 6 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journe y.
&
WARNING Risk of injury orfata l injury
due toa malfunction in there stra int sys‐
te m
If th ere stra int sy stem is malfunctioning,
re stra int sy stem components may be trig‐
ge red unintentionally or might not be trig‐
ge red at all in theeve nt of an accident. This
may af fect the Emer gency Tensioning Device
or airbag, forex ample.
#Ha ve 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:
RFr ontal impact
RRe ar impact
RSide impact
RRo llover 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 measure d
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, forex am‐
ple, this may result in suf ficiently high le vels of
ve hicle deceleration.

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 af terth e self-tes t:
RPASSENGER AIR BAG ON lights up for
60 seconds, subsequently bo thindicator
lamps are off (PASSENGER AIR BAG ON and
OFF): the front passenger airbag is able to
deploy in theev ent of an accident.
RPA SSENGER AIR BAG OFF lights up continu‐
ously: the front passenger airbag is disabled.
It will then not be deplo yed in theeve nt of an
accident.
If th ePA SSENGER AIR BAG ON indicator lamp is
off, only thePA SSENGER AIR BAG OFF indicator
lamp sho wsthest atus of the front passenger
airbag. The PASSENGER AIR BAG OFF indicator
lamp may be lit continuously or be off.
If th ePA SSENGER AIR BAG OFF indicator lamp
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 ins tall

If th ePA SSENGER AIR BAG OFF indicator
lamp remains lit af terth e sy stem self-test,
th e front passenger air bag is deactivated. It
will not be deplo yed in theeve nt of an acci‐

cannot perform its intended pr otective func‐
tion, e.g. when a person is seated in the front
passenger seat.
That person could, forex ample, come into
con tact wi th theve hicle interior, especially if
th e person is sitting too close tothe cockpit.
If th e front passenger seat is occupied,
alw ays ensure that:
RThe classification of the person in the
