The functionality of a roof aerial (tele-
phone, GPS) may be impaired if roof carrier
systems are used.
Attaching metallised retrofit film to the
windscreen may affect radio reception and
have a negative impact on all other aerials
(e.g. emergency aerial) in the vehicle inte-
rior.

Only have work or changes to electronic
components carried out at a qualified spe-
cialist workshop. This workshop should
have the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre. In partic-
ular, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.

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 state
R
events
R
faults
R
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
Operating safety
These include, for example:
operating conditions of system compo-

nents, e.g. fluid levels
the vehicle's status messages and those of

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-

tem components, e.g. lights, brakes
vehicle reactions and operating conditions
R
in special driving situations, e.g. airbag
deployment, intervention of stability con-

The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem-
ory and fault data memory.
Services include, for example:
repair services

service processes
R
warranty events

It is read by employees of the service network
(including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
