QR code for rescue cards
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 rescue card con-
tains, in a compact form, the most important
information about your vehicle, e.g. the routing
of the electric cables.
You can find more information under
www.mercedes-benz.de/qr-code.
Data stored in the vehicle
Many of the electronic components in your vehi-
cle can store data.
These data memories temporarily or perma-
nently store technical information about:
R
the vehicle's operating state
R
events
R
faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R
operating conditions of system components –
for example, fluid levels
R
status messages concerning the vehicle and
its individual components – for example,
wheel rotational speed, vehicle speed, decel-
eration in movement, lateral acceleration,
accelerator pedal position
R
malfunctions and defects in important system
components, for example, lights, brakes
R
vehicle reactions and operating conditions in
special driving situations – for example, air-
bag deployment, intervention of stability con-
trol systems
R
ambient conditions – for example, outside
temperature
These data are of an exclusively technical nature
and can be used to:
R
assist in detecting and rectifying faults and
defects
R
analyse vehicle functions, e.g. after an acci-
dent
R
optimise vehicle functions
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 memory
and fault data memory.
Services include, for example:
R
repair services
R
service processes
R
warranty events
R
quality assurance
The information is read out by employees of the
service network (including the manufacturer)
using special diagnostic testers. You can obtain
more information there, if required.
After a fault has been rectified, the information
is deleted from the fault memory or is continu-
ally overwritten.
During vehicle operation, certain situations may
arise in which these technical data – in conjunc-
tion with other information and, if applicable,
after consultation with an approved assessor –
may be linked to an individual person.
Examples include:
R
accident reports
R
damage to the vehicle
R
witness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for
example, vehicle location in the event of an
emergency.
