General notes
This includes the following data, forexample:
Vehicle status information suchas the speed,
R
longitudinal acceleration, lateral acceleration,
number of wheel revolutions or the fastened
seat belts display
Ambient conditions, suchas temperature, rain
R
sensor or distance sensor
Generally, these are volatile data and will not be
stored beyond the period of operation but will
only be processed within the vehicle itself. Con-
trol units, forexample, vehicle keys, often contain
data memories. Their use permits the temporary
or permanent documentation of technical infor-
mation about the vehicle's operating state, com-
ponent loads, maintenance requirements and
technical events or faults.
Depending on the technical equipment, the fol-
lowing data are stored:
Operating status of system components,
R
suchas fill levels, tyre pressure or battery sta-
tus
Malfunctions or faults in important system
R
components, suchas lights or brakes
System reactions in special driving situations,
R
suchas an airbag deployment or the interven-
tion of stability control systems
information on events leading to vehicle dam-
R
age
In certain cases, storing data that would have oth-
erwise been temporary may be required. This may
be the case if the vehicle has detected a malfunc-
tion, forexample.
If you use services suchas repair services and
maintenance work, stored operational data and
the vehicle identification number can be read out
and used. Service network employees can read
them out, suchas workshops and manufacturers
or third parties, suchas breakdown services. The
same is true in the case of warranty claims and
quality assurance measures.
In general, the readout is performed via the legally
prescribed port for the diagnostics connection in
the vehicle. The operational data that are read out
technical document states of the vehicle or of
individual components and assist in diagnosing
malfunctions, compliance with warranty obliga-
tions and quality improvement. To that end, these

data, particularly information about component
loads, technical events, malfunctions and other
faults, may be transmitted along with the vehicle
identification number to the manufacturer. Fur-
thermore, the manufacturer is subject to product
liability. For this reason, the manufacturer also
uses operational data from the vehicle, forexam-
ple, for recalls. These data can also be used to
examine the customer's warranty and guarantee
claims.
Fault memories in the vehicle can be reset by a
service outlet or at your request as part of repair
or maintenance work.
Convenience and infotainment functions
You can store the vehicle's convenience settings
and individual settings and change or reset them
at any time.
Depending on the vehicle equipment, this
includes the following settings, forexample:
Seat and steering wheel positions
R
Suspension and climate control settings
R
Individual settings, suchas interior lighting
