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

Correct use

If warning stickers are removed, you may fail
to recognise certain dangers. Leave warning
stickers in place.
The following are important sources of infor-
mation in regard to vehicle use:
safety notes in this Owner's Manual
R
technical data in this Owner's Manual
R
traffic rules and regulations
R
laws and safety standards pertaining to
R
motor vehicles
Implied warranty
!
Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions is not covered either by the
smart implied warranty or by the New or
Used-Vehicle Warranty.

QR codes for rescue card

The QR code is on the fuel filler flap and on
the door pillar (B-pillar), on the opposite
side. In the event of an accident, rescue serv-
ices can use the QR code to quickly determine
the corresponding rescue card for a vehicle.
The current rescue card contains the most
important information about the vehicle in
compact form, such as the routing of the
electric cables. Further information:

Data stored in the vehicle

Information from 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 assistance
systems). In addition, your vehicle offers
comfort or entertainment functions which
are also made possible with electronic con-
trol units.
Electronic control units contain data memo-
ries which can permanently or temporarily
store technical information on vehicle con-
dition, component stress, service require-
ments as well as technical incidents and
faults.
This information generally documents the
condition of a component, a module, a system
or of the environment such as:
operating states of system components
R
(e.g. fluid levels, battery status, tyre pres-
sure)
status messages of the vehicle or its indi-
R
vidual components (e.g. wheel revolu-
tions/speed, deceleration in movement,
lateral acceleration, display of seat belts
fastened)
malfunctions and defects in key system
R
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, rain
R
sensor)
In addition to the provision of control unit
functions, this data serves to detect and rec-
tify 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 memories.
When service work is done on your vehicle,
the technical data from the vehicle can be
read out by service network staff or third
parties. Service work is, for example, repair
work, maintenance, warranty claims and
quality assurance measures. The data is read
out using the legally prescribed OBD (Euro-
pean On-board Diagnostics) connector 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.
