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‐

This enables the use of selected smartphone
Apps, e.g. navigation or music playbac k.There is

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‐

restra int sy stem includes thefo llowing:
R Seat belt sy stem
R Airbags
R Child restra int sy stem
R Child seat securing sy stem
The restra int sy stem can reduce therisk of vehi‐
cle occupants coming into contact with parts of
th eve hicle interior in theeve nt of an accident. In
th eev ent of an accident, there stra int sy stem
can also reduce thefo rc es towhich theve hicle
occupants are subjected.
A seat belt can only pr ovide the best le vel of pro‐
te ction if it is worncor rectl y.Depending on the
de tected accident situation, seat belt tensioners
and/or airbags supplement the pr otection
of fere dby a cor rectly wornseat belt. Seat belt
te nsioners and/or airbags are not depl oyed in
ev ery accident. In order
forth ere stra int sy stem toprov ide the
intended le vel of pr otection, each vehicle occu‐
pant must obser vethefo llowing information:
R Fasten seat belts cor rectl y.
R Sit in an almost up right seat position with
th eir back against the seat backrest.
R Sit with their feet resting on thefloor, if pos‐
sible.
R Alw ays secure persons under 1.50 m tall in
an additional restra int sy stem suitable for
Mercedes-Benz vehicles.
Ho wever,no sy stem available today can com‐
ple tely eliminate injuries and fata lities in every
accident situation. In particular, the seat belt
and airbag generally do not pr otect against
objects penetrating theve hicle from the outside.
It is also not possible tocompl etely rule out the

the ignition is switched on, a sy stem self-

WARNING Risk of inju ryor fata l injury
due toa malfunction in there stra int sys‐

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

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
