Customer information317● Faults and defects in importantsystem components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services, the operating
data saved can be read together with the vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.

● Seat and steering wheel position settings,
● Chassis and air conditioning settings,
● Custom settings such as interior lighting.
You can input your own data in the
infotainment functions for your
vehicle as part of the selected

Depending on the equipment level in
question, these include
● Multimedia data such as music, videos or photos for playback in
an integrated multimedia system,
● Address book data for use with an integrated hands-free system
or an integrated navigation
system,
● Input destinations,
● Data on the use of online services.
This data for comfort and
infotainment functions can be stored
locally in the vehicle or be kept on a
