Protecting the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affec-
ted by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel
consumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer
need them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal
when starting the engine.
Rdo not warm up the engine when the vehi-
cle is stationary.
Rdrive carefully and maintain a safe dis-
tance from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each
gear only up to

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 ofits individual components, e.g. number ofwheel revolutions/speed, deceleration inmovement, lateral acceleration, acceleratorpedal position
Rmalfunctions and defects in important sys-tem components, e.g. lights, brakes
Rvehicle reactions and operating conditionsin special driving situations, e.g. air bagdeployment, intervention of stability controlsystems
Rambient conditions, e.g. outside tempera-ture

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 mem-ory and malfunction data memory.
Services include, for example:
Rrepair services
Rservice processes
Rwarranties
Rquality assurance
The vehicle is read out by employees of theservice network (including the manufacturer)using special diagnostic testers. More detailedinformation is obtained from it, if required.
After a malfunction has been rectified, theinformation is deleted from the malfunctionmemory or is continually overwritten.
When operating the vehicle, situations areconceivable in which this technical data, inconnection with other information (if neces-sary, under consultation with an authorizedexpert), could be traced to a person.
Examples include:
Raccident reports
Rdamage to the vehicle
Rwitness statements
Further additional functions that have beencontractually agreed upon with the customerallow certain vehicle data to be conveyed bythe vehicle as well. The additional functionsinclude, for example, vehicle location in caseof an emergency.
COMAND/Mercedes me connect
(Canada: TELEAID)
If the vehicle is equipped with COMAND orMercedes me connect, additional data aboutthe vehicle's operation, the use of the vehiclein certain situations, and the location of thevehicle 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
USA only:
This vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped withan event data recorder (EDR). The main pur-pose of an EDR is to record, in certain crash ornear crash-like situations, such as an air bagdeployment or hitting a road obstacle, datathat will assist in understanding how a vehi-cle's systems performed. The EDR is designedto record data relating to vehicle dynamicsand safety systems for a short period of time,typically 30 seconds or 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 depressingthe accelerator and/or brake pedal; and,
RHow fast the vehicle was traveling
These data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR dataare recorded by your vehicle only if a non-triv-ial crash situation occurs; no data are recor-ded by the EDR under normal driving condi-tions and no personal data (e.g. name, gender,age and crash location) are recorded. How-ever, other parties, such as law enforcementcould combine the EDR data with the type ofpersonally identifying data routinely acquiredduring a crash investigation.
Access to the vehicle and/or the EDR is nee-ded to read data that is recorded by an EDR,and special equipment is required. In additionto the vehicle manufacturer, other parties thathave the special equipment, such as lawenforcement, can read the information byaccessing the vehicle or the EDR.
EDR data may be used in civil and criminalmatters as a tool in accident reconstruction,accident claims and vehicle safety. Since theCrash Data Retrieval CDR tool that is used toextract data from the EDR is commercially

available, Mercedes-Benz USA, LLC ("MBUSA")expressly disclaims any and all liability arisingfrom the extraction of this information byunauthorized Mercedes-Benz personnel.
MBUSA will not share EDR data with otherswithout the consent of the vehicle owners or,if the vehicle is leased, without the consent ofthe lessee. Exceptions to this representationinclude responses to subpoenas by lawenforcement; by federal, state or local govern-ment; in connection with or arising out of liti-gation involving MBUSA or its subsidiaries andaffiliates; or, as required by law.
Warning: The EDR is a component of theRestraint System Module. Tampering with,altering, modifying or removing the EDR com-ponent may result in a malfunction of theRestraint System Module and other systems.
State laws or regulations regarding EDRs thatconflict with federal regulation are pre-emp-ted. This means that in the event of such con-flict, the federal regulation governs. As of Feb-ruary 2013, 13 states have enacted laws relat-ing to EDRs.
