Operating safety
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk
of fire.
When driving on an unpaved road or off-road,
check the vehicle underside regularly. In par-
ticular, remove trapped plant parts or other
flammable material. Contact a qualified spe-
cialist workshop immediately if damage is
detected.
GWARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a highcurb or an unpaved road
Ryou drive too fast over an obstacle, e.g. acurb, a speed bump or a pothole in the road
Ra heavy object strikes the underbody orparts of the chassis
In situations like this, the body, the under-body, chassis parts, wheels or tires could bedamaged without the damage being visible.Components damaged in this way can unex-pectedly fail or, in the case of an accident, nolonger withstand the loads they are designedto.
If the underbody paneling is damaged, com-bustible materials such as leaves, grass ortwigs can gather between the underbody andthe underbody paneling. If these materialscome in contact with hot parts of the exhaustsystem, they can catch fire.
In such situations, have the vehicle checkedand repaired immediately at a qualified spe-cialist workshop. If on continuing your jour-ney you notice that driving safety is impaired,pull over and stop the vehicle immediately,paying attention to road and traffic condi-tions. In such cases, consult a qualified spe-cialist workshop.

Diagnostic connector
The diagnostics connection is only intended forthe connection of diagnostic equipment at aqualified 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 equipmenton the diagnostics connection is used, thestarter battery may discharge.
Connecting equipment to the diagnostics con-nection can lead to emissions monitoring infor-mation being reset, for example. This may leadto the vehicle failing to meet the requirements ofthe next emissions test during the main inspec-tion.

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.
