ger be able to brake, operate the clutch or
accelerate as intended. There is a risk of acci-
dent.

nostic interface can lead to emissions moni-
toring information being reset .This may lead
to the vehicle failing to meet the require-
ments at the next emissions control test or
main inspection.
If the engine is switched off and equipment
on the on-board diagnostic interface is used,
the starter battery may discharge.

Fault data
Components critical for vehicle operation are
equipped with fault data memories as stand-
ard. There are also data storage devices
which record the technical reactions of vehi-
cle components to certain driving situations
(e.g. airbag deployment or ESP ®
interven-
tion).
This data is used exclusively to:

defects

vehicle functions
The data cannot be used to trace the vehicle's

When your vehicle is serviced by Mercedes-
Benz, this technical information can be read
out from the fault memory. This is performed
by authorised employees of the Mercedes-
Ben zservice network using special diagnos-
tic computers. After a fault has been rectified, the informa-
tion is deleted from the memory. Other mem-
ory data is constantly overwritten. Other devices that store data
Depending on the equipment level, your vehi-
cle may feature communications and/or
entertainment systems (e.g. navigation devi-
ces, telephone systems). These allow you to
save and edit data required for the operation
of the respective device.
Further information on operation (e.g. on
deleting data) can be found in the separate
operating instructions. Introduction
