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
fo rve hicle keys,fo rex ample. Their use permits
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-
ments and tech nical events or faults.
Depending on theve hicle equipment, thefo llo w-
ing data are stored:
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
of stability cont rol systems
R information on events leading tovehicle dam-
age In cer
tain cases, it may be requ ired tostore da ta

rari ly. 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, 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 impro vement. 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
service outl etor at your requ est as part of repair
or maintenance work.

aint syst em in an accident
em in an accident How
there straint system 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 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 do not play a deci-
sive role in the deployment of an airbag. Nor do
th ey prov ide an indication of airbag deployment.
The vehicle may be deformed signi/cantly without
an airbag being depl oyed. 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
R Driver's airbag, front passenger airbag: frontal
impact
R Knee airbag: frontal impact
R Side airbag: side impact
R Head airbag: side impact, rollo ver,frontal
impact
The front passenger airbag can only be deplo yed
in an accident if thePA SSENGER AIR BAG OFF
indicator la mpis o.. If the front passenger seat is
occupied, make sure, bo thbefore and during the
journe y,that the status of the front passenger air-
bag is cor rect (/ page 50). 40
