ve hicle underbody or suspension compo-

thefo llowing situations, in particular, there
is a risk of damage totheve hicle:
R theve hicle becomes grounded, e.g. on a
high kerb or an unpa vedro ad
R theve hicle is driven toofast ove r an obsta-
cle, e.g. a kerb, speed bump or po thole
R a heavy object st rike sth e underbody or
suspension components
In situations such as these, damage tothe
body, underbody, suspension components,
wheels or tyres may not be visible. Compo-
nents damaged in this wa y can un expectedly
fa il or, in the case of an accident, may no lon-
ge r absorb there sulting forc e as intended.
If th e underbody panelling is damaged, 0am-
mable materials such as lea ves, grass or twigs
can collect between the underbody and the
underbody panelling. These materials may ignite if
they come into contact with hot parts
of theex haust system. #
Have theve hicle checked and repaired
immediately at a quali/ed specialist
wo rkshop.

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.
