The following text is published as required of
manufacturers under Title 49, Code of U.S. Fed-
eral Regulations, Part 575 pursuant to the
"National Traffic and Motor Vehicle Safety Act of
1966".
If you believe that your vehicle hasadefect
which could cause acrash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration
(NHTSA)ina ddition to notifying Mercedes-Benz
USA,L LC.
If NHTSA receives similar complaints ,itmay
open an investigation, and if it finds that asafety
defect exists in agroup of vehicles, it may order
ar ecall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or Mercedes-Benz
USA,L LC.
To contact NHTSA,y ou may call the Vehicle
Safety Hotlin etoll-free at
1-888-327-4236(TTY: 1-800-424-9153); go to
http://www.safercar.gov ;orwrite to: Admin-

!
Observe the notes in this Operator's Manual
regarding the correcto peration of your vehi-
cle and possible damage to the vehicle. Dam-
age to the vehicle which is caused by violation
of these notes is not covered by the
Mercedes-Benz implied warranty or the new
or used-vehicle warranty.
QR codes for the rescue card
The QR codes are secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident,r escue services can use
the QR code to quickly find the appropriate res- cue card for your vehicle. The current rescue
card contains the most important information
about your vehicle in acompact form, e.g. the
routing of the electric cables.

Data stored in the vehicle
Data storage
Aw
ide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
Rvehicle's operating state
Rincidents
Rmalfunctions
In general, this technical information docu-
mentst he state of acomponent, amodule, 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,l ateral acceleration, accelerator pedal
position
Rmalfunction sand defects in important system
components, e.g. lights, brakes
Rvehicle reactionsa nd operating conditions in
special driving situations, e.g. air bag deploy-
ment,i ntervention of stability control sys-
tems
Rambient conditions, e.g. outside temperature
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 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:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
28Data stored in the vehicle
Introduction

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.
Afteramalfunction 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 aperson.
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.
Event datar ecorders
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 EDRistor ecord, in certain crash or near
crash-lik esituations, such as an air bag deploy-
ment or hittin garoad obstacle, data that will
assist in understanding how avehicle's systems
performed. The ED Risdesigned to record data
related to vehicle dynamics and safety systems
for ashort period of time, typically 30 seconds
or less. The ED
Rinthis 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 the accelerator and/or brake pedal and
RHow fast the vehicle was traveling.
These data can help provide abetter under-
standin gofthe circumstances in which acci-
dents and injuries occur. NOTE: ED Rdata are
recorded by your vehicle only if anon-trivial
crash situation occurs; no data is recorded by
the ED Runder 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 acrash investi-
gation.
Access to the vehicle and/or the ED Risneeded
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 atool in accident reconstruction, acci-
dent claims and vehicle safety. Sincet he Crash
Data Retrieval CDR tool that is used to extract
data from the ED Riscommercially 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 Rdata with others
without the consentoft hevehicle owners or, if
t

he vehicle is leased, without the consen tofthe
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.
Warning: The ED Risacomponent of the
Restraint System Module. Tampering with, alter-
ing, modifying or removing the ED Rcomponent
may result in amalfunction of the Restraint Sys-
tem Module and other systems.
Statel aws or regulations regarding EDRs that
conflict with federal regulation are pre-empted.

Metho dofoperation
During the firs tstag eofac ollision, the restraint
system control uni tevaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Base dont he evaluation of this data, the
restraint system control uni ttriggers the Emer-
gency Tensioning Devices during afrontalo r
rearc ollision. An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational
.You can find further information
under "Restraint system warning lamp"

The front-passenger front ai rbag is activate dor

PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG indicator lamps (

acceleration which occurs at variousp oints in
the vehicle .Thisp rocess is pre-emptive in
nature. Deployment shoul dtake place in good

The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
