Data stored in the vehicle
Data storage
A wide range of electronic components in your
vehicle contain data memories. Introduction 29
Z

These data memories temporarily or perma-
nently store technical information about: R
vehicle's operating state R
incidents R
malfunctions
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,
e.g. fluid levels R
the vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, accelerator pedal
position R
malfunctions and defects in important system
components, e.g. lights, brakes R
vehicle reactions and operating conditions in
special driving situations, e.g. air bag deploy-
ment, intervention of stability control sys-
tems R
ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to: R
assist in recognizing and rectifying malfunc-
tions and defects R
analyze vehicle functions, e.g. after an acci-
dent R
optimize vehicle function
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 malfunction data memory.
Services include, for example: R
repair services R
service processes R
warranties R
quality assurance
The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using
special diagnostic testers. More detailed infor-
mation is obtained from it, if required.
After a malfunction has been rectified, the infor-
mation is deleted from the malfunction memory
or is continually overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec- tion with other information (if necessary, under
consultation with an authorized expert), could
be traced to a 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 case of an emer-
gency.
COMAND/mbrace If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle's
operation, the use of the vehicle in certain sit-
uations, and the location of the vehicle may be
compiled through COMAND or the mbrace sys-
tem.
For additional information please refer to the
COMAND User Manual or the Digital Operator's
Manual and/or the mbrace Terms and Condi-
tions.
Event data recorders This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deploy-
ment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less.
The EDR in this vehicle is designed to record
such data as: R
How various systems in your vehicle were
operating R
Whether or not the driver and passenger
safety belts were buckled/fastened R
How far (if at all) the driver was depressing the
accelerator and/or brake pedal and R
How fast the vehicle was traveling.30
Introduction

Useful information
i This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.
i Read the information on qualified specialist
workshops ( Y
page 28).
Information regarding technical data
i The data stated here specifically refers to a
vehicle with standard equipment. Consult an
authorized Mercedes-Benz Center for the
data for all vehicle variants and trim levels.
Vehicle electronics
Retrofitting two-way radios and
mobile phones (RF transmitters)
G WARNING
The electromagnetic radiation from modified
or incorrectly retrofitted RF-transmitters can
interfere with the vehicle electronics. This can
compromise the operational safety of the
vehicle. There is a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
G WARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can interfere
with the vehicle electronics, for example: R
if the RF transmitter is not connected with
an exterior antenna R
the exterior antenna has been installed
incorrectly or is not a low-reflection type
This can compromise the operational safety
of the vehicle. There is a risk of an accident. Have the low-reflection exterior antenna
mounted at a qualified specialist workshop.
When operating RF transmitters in the vehi-
cle, always connect them with the low-reflec-
tion exterior antenna.
! The operating permit may be invalidated if
the instructions for installation and use of RF
transmitters are not observed.
In particular, the following conditions must be
complied with: R
only approved wavebands may be used. R
compliance with the maximum permissible
output in these wavebands is required. R
only approved antenna positions may be
used.
Excessive levels of electromagnetic radiation
may cause damage to your health and the health
of others. Using an exterior antenna takes into
account current scientific discussions relating
to the possible health hazards that may result
from electromagnetic fields.
