ur vehicle as well as on possible vehi‐
cle damage. QR code
forre scue card
The QR code is secured 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 http://
www.mercedes-benz.de/qr-code. Data
storage Electronic control units
Elect
ronic control units are fitted in your vehicle.
Some of these are necessary forth e safe opera‐
tion of your vehicle, while some assist you when
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 cantemp 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 states of sy stem components (e.g.
fl uid le vels, battery status, tyre pressure)
R status messages concerning theve hicle or
its individual components (e.g. number of
wheel revo lutions/speed, decele ration in
mo vement, lateral accele ration, display of
fast ened seat belts)
R malfunctions or defects 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 cases and quality assurance
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 transmit tedto the manufacturer, if neces‐
sar y.Fu rthermore, the manufacturer is subject General no

Re
stra 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:
R the6 restra int sy stem warning lamp does
not light up when the ignition is switched on
R the6 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journey &
WARNING Risk of inju ryor fata l injury
due toa malfunction in there stra int sys‐
tem
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 theev ent of an accident. This
may af fect the seat belt tensioner or airbag,
fo rex ample. #
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 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.
Fa ctors whi chcan only be seen and measu red
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. Occupant saf

WARNING Risk of inju ryor death when
th ePA SSENGER AIR BAG OFF indicator
lamp is lit
If th ePA SSENGER AIR BAG OFF indicator
lamp remains lit af terth e sy stem self-test,
th e front passenger airbag is disabled. It will
not be deplo yed in theeve nt of an accident.
In this case, the front passenger airbag can‐
not per form its intended pr otective function,
e.g. when a person is seated in the front
passenger seat.
That person could, forex ample, come into
