Mercedes-Benz E-Class Wagon, Operator'S Manual

Page: 29 / 510

In general, this information documents the state
of a component part, a module, a system or the
surroundings, for example:
R
operating statuses of system components
(e.g. fluid levels, battery status, tire pressure)
R
status messages concerning the vehicle and
its individual components (e.g. number of
wheel revolutions/speed, deceleration, lat‐
eral acceleration, display of the fastened seat
belts)
R
malfunctions or defects in important system
components (e.g. lights, brakes)
R
information on vehicle damage events
R
system reactions in special driving situations
(e.g. air bag deployment, intervention of sta‐
bility control systems)
R
ambient conditions (e.g. temperature, rain
sensor)
In addition to providing the actual control unit
function, this data assists the manufacturer in
detecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this
data is temporary and is only processed in the
vehicle itself. Only a small portion of the data is
stored in the event or malfunction memory.
When your vehicle is serviced, technical data
from the vehicle can be read out by service net‐
work employees or third parties. Services
include repair services, maintenance processes,
warranty events and quality assurance meas‐
ures, for example. The read out is performed via
the legally prescribed port for OBD ("on-board
diagnostics") in the vehicle. The respective
service network locations or third parties col‐
lect, process and use the data. They document
technical statuses of the vehicle, assist in find‐
ing malfunctions and improving quality and are
transmitted to the manufacturer, if necessary.
Furthermore, the manufacturer is subject to
product liability. For this, the manufacturer
requires technical data from vehicles.
Malfunction memories in the vehicle can be
reset by a service outlet as part of repair or
maintenance work.
They can enter data into the vehicle's conveni‐
ence and infotainment functions themselves as
part of the selected equipment.
This includes, for example:
R
multimedia data such as music, films or pho‐
tos for playback in an integrated multimedia
system
R
address book data for use in connection with
an integrated hands-free system or an inte‐
grated navigation system
R
entered navigation destinations
R
data about the use of Internet services
This data can be stored locally in the vehicle or
is located on a device which you have connected
to the vehicle. If this data is stored in the vehi‐
cle, you can delete it at any time. This data can
only be transmitted to third parties upon your
request with particular regard to the scope of
use of online services according to your selected
settings.
You can store or change convenience settings/
individualization in the vehicle at any time.
Depending on the equipment, this includes, for
example:
R
seat and steering wheel position settings
R
suspension and climate control settings
