Diagnostics connection
The diagnostics connection is only intended for
the connection of diagnostic equipment at a
qualified specialist workshop.
GWARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the
operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz.
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
!If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor- mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec-
tion.

Data stored in the vehicle
Data storage
A wide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
Rthe vehicle's operating state
Rincidents
Rmalfunctions
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
Roperating conditions of system components,
e.g. fluid levels
Rthe 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
Rmalfunctions and defects in important system
components, e.g. lights, brakes
Rvehicle reactions and operating conditions in
special driving situations, e.g. air bag deploy-
ment, intervention of stability control sys-
tems
Rambient conditions, e.g. outside temperature
30Introduction

This data is of an exclusively technical nature
and can be used to:
Rassist in recognizing and rectifying malfunc-
tions and defects
Ranalyze vehicle functions, e.g. after an acci-
dent
Roptimize vehicle functions
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:
Rrepair services
Rservice processes
Rwarranties
Rquality 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:
Raccident reports
Rdamage to the vehicle
Rwitness 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.
COMAND/mbrace

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:
RHow various systems in your vehicle were
operating
RWhether or not the driver and passenger
safety belts were buckled/fastened
RHow far (if at all) the driver was depressing theaccelerator and/or brake pedal and
RHow fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which crashes and injuries occur. NOTE: EDR data are recorded
by your vehicle only if a non-trivial crash situa-
tion occurs; no data are recorded by the EDR
under normal driving conditions and no personal
data (e.g. name, gender, age and crash location)
are recorded. However, other parties, such as
law enforcement could combine the EDR data
with the type of personally identifying data rou-
tinely acquired during a crash investigation.
Access to the vehicle and/or the EDR is needed
to read data that is recorded by an EDR, and
Introduction31
Z

special equipment is required. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment, can read the information by accessing thevehicle or the EDR.
EDR data may be used in civil and criminal mat-
ters as a tool in accident reconstruction, acci-
dent claims and vehicle safety. Since the Crash
Data Retrieval CDR tool that is used to extract
data from the EDR is commercially available,
Mercedes-Benz USA, LLC ("MBUSA") expressly
disclaims any and all liability arising from the
extraction of this information by unauthorized
Mercedes-Benz personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or, if
the vehicle is leased, without the consent of the
lessee. Exceptions to this representation
include responses to subpoenas by law enforce-
ment; by federal, 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.
Warning: The EDR is a component of the
Restraint System Module. Tampering with, alter-
ing, modifying or removing the EDR component
may result in a malfunction of the Restraint Sys- tem Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-empted.
This means that in the event of such conflict, the federal regulation governs. As of February 2013,
13 states have enacted laws relating to EDRs.
