Qr Codes For Rescue Card; Data Stored In The Vehicle - SMART EQ forfour 2018 Owner's Manual

QR codes for rescue card

The QR code is affixed on the charge socket
flap and on the door pillar (B-pillar), on the
opposite side. In the event of an accident,
rescue services can use the QR code to
quickly determine the corresponding res-
cue card for a vehicle. The current rescue
card contains the most important informa-
tion about the vehicle in compact form,
such as the routing of the electric cables.

Data stored in the vehicle

Electronic control units
Your vehicle is equipped with electronic
control units. Some of them are necessary
for your vehicle to function safely, some
provide support when driving (driver assis-
tance systems). In addition, your vehicle
offers comfort or entertainment functions
which are also made possible with elec-
tronic control units.
Electronic control units contain data mem-
ories which can permanently or tempora-
rily store technical information on vehicle
condition, component stress, service
requirements as well as technical incidents
and faults.
This information generally documents the
condition of a component, a module, a sys-
tem or of the environment such as:
operating states of system components
R
(e.g. fluid levels, battery status, tyre
pressure)
status messages of the vehicle or its
R
individual components (e.g. wheel revo-
lutions/speed, deceleration in movement,
lateral acceleration, display of seat belts
fastened)
malfunctions and defects in important
R
system components (e.g. the lights and
brakes)
information on incidents in which the
R
vehicle is damaged
reactions of the systems in specific driv-
R
ing situations (e.g. deployment of an air-
bag, use of stability control systems)
ambient conditions (e.g. temperature,
R
rain sensor)
In addition to the provision of control unit
functions, this data serves to detect and
rectify faults as well as to optimise vehicle
functions by the manufacturer. Most of this
data is volatile and is only processed in the
vehicle itself. Only a small proportion of
the data is stored in event or error memo-
ries.
When service work is carried out on your
vehicle, the technical data from the vehicle
can be read out by service network staff
(e.g. workshops, manufacturers) or third
parties (e.g. breakdown services). Service
work is, for example, repair work, mainte-
nance, warranty claims and quality assur-
ance measures. The data is read out via the
legally prescribed connection for the diag-
nostics connection in the vehicle. The
respective workshop of service network or
third parties collect, process and use the
data. The data documents technical states
of the vehicle, help in finding errors and in
improving quality and are transferred to
the manufacturer if necessary. In addition,
the manufacturer is subject to product lia-
bility. For this purpose, the manufacturer
requires technical data from vehicles.
Error memories in the vehicle can be reset
by a service outlet during repairs or service
work.
Depending on the equipment selected, you
can enter data in comfort and infotainment
functions of the vehicle.
This includes, for example:
multimedia data, such as music, films or
R
photos for playback in an integrated
multimedia system
address book data for use in an integra-
R
ted hands-free system or an integrated
navigation system
navigation destinations entered
R
data on the use of Internet services
R
This data can be saved locally in the vehi-
cle or it is located on a device which you
have connected to the vehicle (e.g. smart-
phone, USB memory stick or MP3 player). If
this data is saved in the vehicle, you can
delete it at any time. Transfer of this data
