tent requ ired, data stored bythe manufac‐
turer. Forex ample, this may be the case during
th e in vestigation of a criminal of fence.
Go vernmental entities are themselves, in individ‐
ual cases and within the applicable legal frame‐
wo rk, authorised toread out data from theve hi‐
cle. In the case of an accident, information that
can help with an in vestigation can, therefore, be
ta ke n from the airbag control unit, forex ample.
Operational data in theve hicle
This is data rega rding the operation of theve hi‐
cle, which ha vebeen processed bycontrol units.
This includes thefo llowing data, forex ample:
R vehicle status information such as the speed,
longitudinal acceleration, lateral accelera‐
tion, number of wheel revo lutions or thefa s‐
te ned seat belts displ ay
R ambient conditions, such as temp erature,
ra in sensor or dis tance sensor
General ly,th e use of these data is temp orar y;
th ey will not be stored be yond the period of
operation and will only be processed within the
ve hicle itself. Control units of ten contain da tamemories
forve hicle keys,fo rex ample. Their
use permits thete mp orary or permanent docu‐
mentation of tech nical information about the
ve hicle's operating state, component loads,
main tenance requ irements and tech nical events
or faults.
Depending on theve hicle equipment, thefo llow‐
ing data are stored:
R operating status of sy stem components,
such as fill le vels, tyre pressure or battery
st atus
R malfunctions or faults in impor tant sy stem
components, such as lights or brakes
R system reactions in special driving situations,
such as airbag deployment or the inter ven‐
tion of stability control sy stems
R information on events leading tovehicle
damage
In cer tain cases, it may be requiredtostore data
th at wo uld ha veotherwise been used only tem‐
porarily. This may be the case if theve hicle has
de tected a malfunction, forex ample. If
yo u use services, such as repair services and
maintenance work,st ored operational data as
we ll as theve hicle identification number can be
re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manufacturers or third parties, such as
breakdown services. The same is true in the
case of warranty claims and quality assurance
measures.
In general, there ad out is per form ed via the
legally prescribed port forth e diagnostics con‐
nection in theve hicle. The operational data that
are read out document tech nical states of the
ve hicle or of individual components and assist in
th e diagnosis of malfunctions, compliance with
wa rranty obligations and quality impr ovement.
To that end, these data, in particular information
about component loads, tech nical events, mal‐
functions and other faults may be transmit ted
along with theve hicle identification number to
th e manufacturer. Furthermore, the manufac‐
turer is subject toproduct liability. Forth is rea‐
son the manufacturer also uses operational data
from theve hicle, forex ample, forre calls. These 34

WARNING Risk of injury duetomalfunc‐
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

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 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 Front seat belt tensioner: frontal impact, rear
impact, side impact, rollo ver 1
R Rear seat belt tensioner: frontal impact, rear
impact, rollo ver 1
R Driver's airbag, front passenger airbag: fron‐
talimpact
R Knee airbag: frontal impact
R Side airbag: side impact
R Window airbag: side impact, rollo ver 1

PLUS (anticipatory
occupant pr otection plus) PRE-
SAFE®
PLUS can de tect cer tain impacts,
particular lyan imminent rear impact, and take
pre-em ptive measures toprotect theve hicle
occupants. These measures cannot necessarily
pr eve nt an imminent impact.
PRE-SAFE ®
PLUS can implement thefo llowing
measures independently of each other:
R Tightening the seat belts on the driver's seat
and front passenger seat.
R Activating there ar hazard warning lights at a
higher flashing frequenc y.
R Increasing brake pressure when theve hicle
is stationar y.This brake application is cancel‐
led automatically when theve hicle pulls
aw ay. If an accident did not occur,
the pre-em ptive
measures that we retake n are reve rsed.
Sy stem limits
The sy stem will not initiate any action in thefo l‐
lowing situations:
R when reve rsing
or
R when theve hicle is towing a trailer and there
is a risk of a rear impact
The sy stem will not initiate any braking applica‐
tion in thefo llowing situations:
R whilst driving
or
R when entering or exiting a parking space
while using Active Parking Assist Safely transporting
children in theve hicle Alw
ays obser vewhen children are tr avelling
in theve hicle %
Also strictly obser vethe saf ety no tesfo rthe
specific situation. In this wa yyo u can recog‐ nise po
tential risks and avoid dangers if chil‐
dren are tr avelling in theve hicle
(/ page 53).
Be diligent
Bear in mind that negligence when securing a
ch ild in thech ild restra int sy stem may ha veseri‐
ous consequences. Alw ays be diligent in secur‐
ing a child carefully before everyjou rney.
To impr oveprotection forch ildren younger than
12 years old or under 1.50 m in height,
Mercedes-Benz recommends you obse rvethe
fo llowing information:
R Alw ays secure thech ild in a child restra int
sy stem suitable forth is Mercedes-Benz vehi‐
cle.
R The child restra int sy stem must be appropri‐
ate tothe age, weight and size of thech ild.
R The vehicle seat must be suitable forfitting a
ch ild restra int sy stem (/ page57).
Ac cident statistics show that children secured
on there ar seats are general lysafer than chil‐
dren secured on the front seats. Forth is reason, 52
