Data storage
Data storage
A wide range of electronic components in yourvehicle 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, asystem or the surroundings.
These include, for example:
Roperating conditions of system components.For example, fluid levels
Rthe vehicle's status messages and those of itsindividual components, e.g. number of wheelrevolutions/speed, deceleration in move-ment, lateral acceleration, accelerator pedalposition
Rmalfunctions and defects in important systemcomponents, e.g. lights, brakes
Rvehicle reactions and operating conditions inspecial driving situations, e.g. air bag deploy-ment, intervention of stability control sys-tems
Rambient conditions, e.g. outside temperature
This data is of an exclusively technical natureand 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'smovements.
When your vehicle is serviced, technical infor-mation can be read from the event data memoryand 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) usingspecial diagnostic testers. More detailed infor-mation is obtained from it, if required.
Data storage29
Introduction
Z

After a malfunction has been rectified, the infor-mation is deleted from the malfunction memoryor is continually overwritten.
When operating the vehicle, situations are con-ceivable in which this technical data, in connec-tion with other information (if necessary, underconsultation with an authorized expert), couldbe 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 allowcertain vehicle data to be conveyed by the vehi-cle as well. The additional functions include, forexample, vehicle location in case of an emer-gency.
COMAND/Mercedes me connect
If the vehicle is equipped with COMAND orMercedes me connect, additional data aboutthe vehicle's operation, the use of the vehicle incertain situations, and the location of the vehi-cle is compiled through COMAND or theMercedes me connect system.
For additional information, please refer to theCOMAND User Manual or Digital Operator'sManual and/or the Mercedes me connectTerms and Conditions.
Event data recorders
This vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped with anevent data recorder (EDR). The main purpose ofan EDR is to record, in certain crash or nearcrash-like situations, such as an air bag deploy-ment or hitting a road obstacle, data that willassist in understanding how a vehicle's systemsperformed. The EDR is designed to record datarelating to vehicle dynamics and safety systemsfor a short period of time, typically 30 secondsor less.
The EDR in this vehicle is designed to recordsuch data as:
RHow various systems in your vehicle wereoperating
RWhether or not the driver and passengersafety 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 crashesand injuries occur. NOTE: EDR data are recordedby your vehicle only if a non-trivial crash situa-tion occurs; no data are recorded by the EDRunder normal driving conditions and no personaldata (e.g. name, gender, age and crash location)are recorded. However, other parties, such aslaw enforcement could combine the EDR datawith the type of personally identifying data rou-tinely acquired during a crash investigation.
Access to the vehicle and/or the EDR is neededto read data that is recorded by an EDR, andspecial equipment is required. In addition to thevehicle manufacturer, other parties that havethe 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 CrashData Retrieval CDR tool that is used to extractdata from the EDR is commercially available,Mercedes-Benz USA, LLC ("MBUSA") expresslydisclaims any and all liability arising from theextraction of this information by unauthorizedMercedes-Benz personnel.
MBUSA will not share EDR data with otherswithout the consent of the vehicle owners or, ifthe vehicle is leased, without the consent of thelessee. Exceptions to this representationinclude responses to subpoenas by law enforce-ment; by federal, state or local government; inconnection 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 theRestraint System Module. Tampering with, alter-ing, modifying or removing the EDR componentmay result in a malfunction of the Restraint Sys-tem Module and other systems.
State laws or regulations regarding EDRs thatconflict with federal regulation are pre-empted.This means that in the event of such conflict, thefederal regulation governs. As of February 2013,13 states have enacted laws relating to EDRs.

Introduction

and to have any malfunctioning air bagsrepaired. This will help to make sure the air bagscontinue to perform their protective function forthe vehicle occupants in the event of a crash.
GWARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a
qualified specialist workshop.
If Emergency Tensioning Devices are triggeredor air bags are deployed, you will hear a bang,and some powder may also be released. Theurestraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-ing. The powder that is released generally doesnot constitute a health hazard, but it may causeshort-term breathing difficulties in people withasthma or other respiratory problems. Providedit is safe to do so, you should leave the vehicleimmediately or open the window in order to pre-vent breathing difficulties.
Air bags and pyrotechnic Emergency TensioningDevices (ETDs) contain perchlorate material,which may require special handling and regardfor the environment. National guidelines mustbe observed during disposal. In California, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.
Method of operation
During the first stage of a collision, the restraintsystem control unit evaluates important physi-cal data relating to vehicle deceleration or accel-eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, therestraint system control unit triggers the Emer-gency Tensioning Devices during a head-on orrear-end collision.
An Emergency Tensioning Device can only betriggered, if:
Rthe ignition is switched on
Rthe components of the restraint system areoperational. You can find further informationunder "Restraint system warning lamp"(Ypage 41)
Rthe seat belt buckle tongue has engaged inthe belt buckle of the respective front seat
The Emergency Tensioning Devices in the rearpassenger compartment are triggered inde-pendently of the lock status of the seat belts.
If the restraint system control unit detects amore severe accident, further components ofthe restraint system are activated independ-ently of each other in certain frontal collisionsituations:
RFront air bags as well as driver's and front-passenger knee bags
RWindow curtain air bag, if the system deter-mines that deployment can offer additionalprotection to that provided by the seat belt
Depending on the person in the front-passengerseat, the front-passenger front air bag is eitherdisabled or enabled. The front-passenger frontair bag can be deployed in an accident only if thePASSENGER AIR BAG OFF indicator lamp is off.Observe the information on the PASSENGER AIRBAG indicator lamps (Ypage 41).
Your vehicle has two-stage front air bags. At thefirst deployment threshold the front air bag fillswith gas. If the second deployment threshold isthen reached within a few milliseconds, the frontair bag is filled with the maximum quantity ofgas.
The activation threshold of the Emergency Ten-sioning Devices and the air bags is determinedby evaluating the rate of vehicle deceleration oracceleration which occurs at various points inthe vehicle. This process is pre-emptive innature. Deployment should take place in goodtime at the start of the collision.
The rate of vehicle deceleration or accelerationand the direction of the force are essentiallydetermined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehicle
Rthe characteristics of the object with whichthe vehicle has collided
Factors which can only be seen and measuredafter a collision has occurred do not play a deci-

phones (RF transmitters)
GWARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle electron-
ics if two-way radios are manipulated or ret-
rofitted incorrectly. This could jeopardize the
operating safety of the vehicle. There is a risk
of an accident.
You should have all work on electrical and
electronic components carried out at a quali-
fied specialist workshop.
GWARNING
If you incorrectly operate two-way radios in
the vehicle, the electromagnetic radiation
may interfere with the vehicle electronics, for
example if:
Rthe two-way radio is not connected to an
exterior antenna
Rthe exterior antenna is not correctly moun-
ted or is not low-reflection
This could jeopardize the operating safety of
the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
installed at a qualified specialist workshop.
Always connect two-way radios to the low-
reflection exterior antenna when operating in
the vehicle.
!The operating permit may be invalidated ifthe instructions for installation and use oftwo-way radios are not observed.
In particular, the following conditions must becomplied with:
Ronly approved wavebands may be used
Robserve the maximum permissible outputin these wavebands
Ronly approved antenna positions may beused
Excessive levels of electromagnetic radiationmay cause damage to your health and the healthof others. Using an exterior antenna takes intoaccount current scientific discussions relatingto the possible health hazards that may resultfrom electromagnetic fields.
