hicle data storage Information from electronic control units
Electronic 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 con venience and enter tain‐
ment functions, which are also made possible by
electronic 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 status, 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 statuses of sy stem components
(e.g. fluid le vels, battery status, tyre pres‐
sure)
R status messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, decele ration, lat‐
eral acceleration, display of thefa stened seat
belts)
R malfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
R information on vehicle damage events
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 or third parties. Services
include repair services, maintenance processes,
wa rranty events and quality assurance meas‐
ures, forex ample. The read out is per form ed via
th e legally prescribed port for OBD ("on-board
diagnostics") in theve hicle. The respective
service network locations or third parties col‐
lect, process and use the data. They document
te ch nical statuses of theve hicle, assist in find‐
ing faults and impr oving quality and are trans‐
mit tedto the manufacturer, if necessar y.Fu r‐
th ermore, the manufacturer is subject toprod‐
uct liability. Forth is, the manufacturer requ ires
te ch 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.
They can enter data into theve hicle's con veni‐
ence and inf otainment functions themselves as
part of the selected equipment. 28

Re
stra int sy stem functionality When
the ignition is switched on, a sy stem self-
te st is per form ed, during which the6
re stra int sy stem warning lamp lights up. It goes
out no later than a few seconds af terth eve hicle
is star ted. The components of there stra int sys‐
te m are then functional. Malfunctioning
restra int sy stem A malfunction has occur
red in there stra int sys‐
te m if:
R The 6 restra int sy stem warning lamp
does not light up when the ignition is
switched on.
R The 6 restra int sy stem warning lamp
lights up continuously or repeatedly during a
journe y. &
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 theeve nt 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 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 should
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, theve hicle deceleration may be high enough
fo rth is to happen. 32
Occupant saf ety

Objects in
theve hicle interior may pr event an
airbag from functioning cor rectly. Each vehicle
occupant must alw ays make sure of thefo llow‐
ing:
R There are no people, animals or objects
between theve hicle occupants and an air‐
bag.
R There are no objects between the seat, door
and door pillar (B-pillar).
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 cup
holders, attached totheve hicle within the
deployment area of an airbag, e.g. on doors,
side windo wsor side panelling.
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. Re

by the AIRB AGsymbol (→ page 38). &
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. #
You should on lyuse seat co vers that
ha ve been appr oved forth e cor respond‐
ing seats byMercedes-Benz. &
WARNING Risk of inju rydue tomalfunc‐
tions of the sensors in the door panelling
Sensors tocontrol the airbags are located in
th e doors. Modifications or worknot per‐
fo rm ed cor rectly tothe doors or door panel‐
ling, as well as damaged doors, can lead to
th e function of the sensors being impaired.
The airbags might therefore not function
