standard. Only use tyres, wheels and acces-
sory parts that are approved for your type of
vehicle.
Genuine Mercedes-Benz parts and conver-
sion parts and accessories that have been
approved for your vehicle are tested by
Mercedes-Benz for:
reliability

safety

suitability

Despite ongoing market research, Mercedes-
Benz is unable to assess other parts.
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz vehi-
cles, even if they have been independently or
officially approved.
In Germany, certain parts are only officially
approved for installation or modification if
they comply with legal requirements. This
also applies to some other countries. All gen-
uine Mercedes-Benz parts meet the approval
requirements. The use of non-approved parts
may invalidate the vehicle's general operating
permit.
This is the case if:
it results in a change to the vehicle type
R
from that for which the vehicle's general
operating permit was granted
they pose a possible risk for road users
R
they adversely affect the emission or noise
R
levels
Always specify the vehicle identification num-
ber (VIN) when ordering genuine Mercedes-
Benz parts ( Y page 356).
Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
the vehicle's operating status
R
events
R
malfunctions
R
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
This includes, for example:
operating conditions of system compo-
R
nents, e.g. fluid levels.
the vehicle's status messages and those of
R
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position.
malfunctions and defects in important sys-
R
tem components, e.g. the brakes.
the vehicle's reactions and operating sta-
R
tuses in special driving situations.
ambient conditions, e.g. outside tempera-
R
ture.
This data is exclusively technical in nature
and can be used to:
assist in the detection and rectification of
R
faults and defects
analyse vehicle functions, e.g. after an acci-
R
dent
optimise vehicle functions
R
The data cannot be used to trace the vehicle's
movements.
When you use one of the available services,
technical information may be read from the
event data memory and fault data memory.
Services include, for example:
repair services
R
service processes
R
warranty claims
R
quality assurance
R
It is read by service network employees
(including the manufacturer) using special
diagnostic testers. Further information is
available there if required.
