R vehicle status information such as the speed,
longitudinal acceleration, lateral acceleration,
number of wheel revo lutions or thefa stened
seat belts display
R ambient conditions, su chastemp erature, rain

Generall y,the use of these data is temp orar y;
th ey will not be stored be yond the period of oper-
ation and will only be processed within theve hicle
itself. Control units oTen contain data memories

th ete mp orary or permanent documentation of
te ch nical information about theve hicle's operat- ing state, component loads, main
tenance requ ire-

Depending on theve hicle equipment, thefo llo w-

R operating status of system components, such
as /ll le vels, tyre pressure or battery status
R malfunctions or faults in impor tant system
components, such as lights or brakes
R system reactions in special driving situations,
such as airbag depl oyment or the inter vention

de tected a malfunction, forex ample.
If yo u use services, such as repair services and
maintenance work, stored operational data as
we ll as theve hicle identi/cation number can be
re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manu facturers or third parties, such as break- down services. The same is true in
the case of
wa rranty claims and quality assurance measures.
In general, there adout is per form ed via the legally
prescribed port forth e diagnostics connection in
th eve hicle. The operational data that are read out
document tech nical states of theve hicle or of
individual components and assist in the diagnosis
of malfunctions, compliance with warranty obli ga-
tions and quality impr ovement. Tothat end, these
data, in particular information about component
loads, tech nical events, malfunctions and other
fa ults may be transmitted along with theve hicle
identi/cation number tothe manufacturer. Fur-
th ermore, the manufacturer is subject toproduct
liability. Forth is reason the manufacturer also
uses operational data from theve hicle, forex am-
ple, forre calls. These data can also be used to
ex amine the customer's warranty and guarantee
claims.
Fa ult memories in theve hicle can be reset by a

The restraint system can help pr eventtheve hicle
occupants from coming into contact with parts of
th eve hicle interior in theev ent of an accident. In
th eev ent of an accident, there straint system can
also reduce thefo rc es towhich theve hicle occu-
pants 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 o.ered
by a cor rectly wornseat belt. Seat belt tensioners
and/or airbags are not deplo yed in every acci-
dent. In order
forth ere straint system toprov ide the
intended le vel of pr otection, each vehicle occu-
pant must obser vethefo llowing information:
R Fasten seat belts co rrectl y.
R Sit in an almost up right seat position with their
back against the seat backrest.
R Sit with their feet resting on the 0oor, if possi-
ble.
R Always secure persons under 1.50 m tall in an
additional restraint system suitable for
Mercedes-Benz vehicles.
Ho wever,no system available today can com-
ple tely eliminate injuries and fatalities 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 tocomple tely rule out therisk of
injury caused bythe airbag deploying. Limit Limit

aint syst em in an accident
em in an accident How
there straint system works depends on the
se verity of the impact de tected and the apparent
type of accident:
R Frontal impact
R Rear impact
R Side impact
R Rollover
The activation thre sholds forth e components of
th ere straint system are de term ined based on the
ev aluation of the sensor values measured at vari-
ous points in theve hicle. This process is pre-e mp-
tive in nature. The triggering/deployment of the
components of there straint system must take
place in good time at the start of the collision.
Fa ctors which can only be seen and measured
aTer a collision has occur red cannot play a deci- sive
role in airbag deployment. Nor do they pro-
vide an indication of airbag deployment.
The vehicle may be deformed signi/cantly without
an airbag being deplo yed. This is the case if only
parts which are relatively easily deformed are
a.ec tedand thera te of vehicle deceleration is
not high. Con versely, an airbag may be depl oyed
ev en though theve hicle su.ers only minor defor-
mation. If very rigid vehicle parts such as longitu-
dinal membe rsare hit, this may result in su1-
ciently high le vels of vehicle deceleration.
Depending on the de tected deployment situation,
th e components of there straint system can be
acti vated or deplo yed independently of each
ot her:
R Seat belt tensioner: frontal impact, rear
impact, side impact, rollo ver

The airbag parts are hot aTer an airbag has
been deplo yed. #
Do not touch the airbag parts. #
Have a depl oyed airbag replaced at a
qu ali/ed specialist workshop as soon as
possible. Mercedes-Benz
recommends that you ha vethe
ve hicle towe dto aqu ali/ed specialist workshop
aTer an accident. Take this into account, particu-
lar lyif a seat belt tensioner is triggered or an air-
bag deplo yed. If
th e seat belt tensioners are triggered or an air-
bag is deplo yed, you will hear a bang, and a small
amount of powder may also be released:
R The bang will not generally a.ect your hearing.
R Ingeneral, the powder released is not hazard-
ous tohealth but may cause short- term
breathing di1culties topersons su.ering from
asthma or other pulmonary conditions.
