Data stored in the vehicle
Introduction
Page 31 of 298

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 am alfunction 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 ap erson.
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 (Canada: TELEAID) 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 dat ar ecordersThis vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an ED Ristor ecord, in certain crash or near
crash-lik es ituations, such as an air bag deploy-
ment or hittin gar oad obstacle, data that will
assist in understanding how av ehicle's systems
performed. The ED Risd esigned to record data
related to vehicle dynamics and safety systems
for as hort period of time, typically 30 seconds
or less. The ED Rint his 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.
These data can help provide ab etter under-
standin goft he circumstances in which acci-
dents and injuries occur. NOTE: ED Rd ata are
recorded by your vehicle only if an on-trivial
crash situation occurs; no data is recorded by
the ED Ru nder normal driving conditions and no
personal data (e.g. name, gender, age and acci-
dent location) are recorded. However, other par-
ties, such as law enforcement could combine
ED Rd ata with the type of personally identifying
data routinely acquired during ac rash investi-
gation.
Access to the vehicle and/or the ED Risn eeded
to read data that is recorded by the EDR, and
special equipment is required. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment ,c an read the information by accessing the
vehicle or the EDR.
ED Rd ata may be used in civil and criminal mat-
ters as at ool in accident reconstruction, acci-
dent claims and vehicle safety. Sinc et he Crash
Data Retrieval CDR tool that is used to extract
data from the ED Risc ommercially available,
Mercedes-Benz USA ,L LC ("MBUSA") expressly
disclaims any and all liability arising from the
extraction of this information by unauthorized
Mercedes-Benz personnel.
MBUSA will not share ED Rd ata with others
without the consen toft he vehicle owners or, if
t he vehicle is leased, without the consen toft he
lessee. Exceptions to this representation
include responses to subpoenas by law enforce-
ment ;byf ederal, state or local government; in
connection with or arising out of litigation involv-
ing MBUSA or its subsidiaries and affiliates; or,
as required by law.
