QR code for rescue card
The QR code is secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident, rescue services can use
the QR code to quickly find the appropriate
rescue card for your vehicle. The current res-
cue card contains, in a compact form, the
most important information about your vehi-
cle, e.g. the routing of the electric cables.

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.
These include, 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. lights, brakes
vehicle reactions and operating conditions
R
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
ambient conditions, e.g. outside tempera-
R
ture
This data is of an exclusively technical nature
and can be used to:
assist in detecting and rectifying faults and
R
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 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
R
service processes
R
warranty events
R
quality assurance
R
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
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
accident reports
R
damage to the vehicle
R
witness statements
R
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case
of an emergency.
