Operating safety
\nWARNINGRisk of accident duetomal‐functions or systemfailures
Ifyou do not havethe prescribed service/maintenanceworkor anyrequiredrepairscarried out,this couldresult in malfunctionsor systemfailures.
Always havethe prescribed service/maintenanceworkaswell anyrequiredrepairs carried out at aqualified spe‐cialistworkshop.
\nWARNINGRisk of accident or injuryduetoincorrect modifications on electroniccomponent parts
Modification of electronic components,theirsoftware or wiring could impairtheir function
and/orthe function ofother networked com‐ponent parts. In particular, systemsrelevanttosafety could also be affected.
As aresult,these may no longer functionproperlyand/or jeopardizethe operatingsafety ofthevehicle.
Nevertamper withthe wiring and elec‐tronic component parts ortheir soft‐ware.
You should haveallworkon electricaland electronic components carried outat aqualified specialistworkshop.
Observethe "On-board electronics" section in"Technical data".
\nWARNINGRisk offireduetoflammablematerials on hot parts oftheexhaustsystem
Flammable material such as leaves, grass ortwigs may ignite iftheycome into contactwithhot parts oftheexhaust system.
When driving on unpavedroads or off-road,regularlycheckthevehicle under‐side.
Removetrapped plants orotherflam‐mable material.
Ifthere is damage, consult aqualifiedspecialistworkshop immediately.
NOTEDamagetothevehicle
Inthefollowing situations, in particular,thereis arisk of damagetothevehicle:
RThevehicle becomes grounded, e.g. on ahigh curb or an unpavedroad
RThevehicle is driventoofastover anobstacle, e.g. a curb, speed bumpor pot‐hole
RA heavy objectstrikesthe underbody orchassis components
In situations such asthis,the body,theunderbody,chassis components, wheels ortires could be damaged withoutthe damagebeing visible. Components damaged inthis

\nWARNINGRisk of accident duetoobjects inthe driver'sfootwell
Objects inthe driver'sfootwell may impedepedal travel or block a depressed pedal.
This jeopardizesthe operating androadsafety ofthevehicle.
Stowall objects inthevehicle securelysothattheycannotgetintothe driver'sfootwell.
Always installthefloor mats securelyand as prescribed in ordertoensurethatthere is always sufficientroomforthe pedals.
Do not use loosefloor mats and do notplacefloor mats ontop of one another.
NOTEBattery discharging from usingdevices connectedtothe diagnosticsconnection
Using devices atthe diagnostics connectiondrainsthe battery.
Checkthechargelevel ofthe battery.
Ifthechargelevel is low,chargethebattery,e.g.bydriving a considerabledistance.
Connecting equipmenttothe diagnostics con‐nection can leadtoemissions monitoring infor‐mation beingreset,forexample. This may leadtothevehiclefailingtomeettherequirements ofthe next emissions inspection duringthe maininspection.

QR codeforrescue card
The QR code is secured inthe fuelfillerflap andonthe opposite side onthe B-pillar. Intheeventof an accident,rescue services can usethe QRcodetoquicklyfindthe appropriaterescue cardforyourvehicle. The currentrescue card con‐tainsthe most important information aboutyourvehicle in a compactform, e.g.therouting oftheelectric lines.
Further information can be obtained at http://www.mercedes-benz.de/qr-code.
Datastorage
Electronic control units
Electronic control units are installed inyourvehi‐cle. Some ofthese are necessaryforthe safeoperation ofyourvehicle, while some assistyouwhen driving (driver assistance systems). Inaddition,yourvehicle provides comfortandentertainment functions, which are also madepossiblebyelectronic control units.
Electronic control units contain datamemorieswhichcantemporarily or permanentlystore
technical information aboutthevehicle's operat‐ingstate, component loads, maintenancerequirements andtechnicalevents or malfunc‐tions.
Ingeneral,this information documentsthestateof a component part, a module, a system orthesurroundings such as:
Roperatingstatus of system components (e.g.fill levels, batterystatus, tire pressure)
Rstatus messages concerningthevehicle orits individual components (e.g. number ofwheelrevolutions/speed, longitudinal accel‐eration, lateral acceleration, display offas‐tened seat belts)
Rmalfunctions orfaults in important systemcomponents (e.g. lights, brakes)
Rinformation onevents leadingtovehicledamage
Rsystemreactions in special driving situations(e.g. airbag deployment, intervention ofsta‐bility control systems)
Rambient conditions (e.g.temperature,rainsensor)
In additiontoprovidingthe actual control unitfunction,this data assiststhe manufacturer indetecting andrectifying malfunctions and opti‐mizingvehicle functions. The majority ofthisdata istemporary and is only processed inthevehicle itself. Only a small portion ofthe data isstored intheevent or malfunction memory.
Whenyourvehicle is serviced,technical datafromthevehicle can beread outbyservice net‐workemployees (e.g.workshops, manufactur‐ers) orthird parties (e.g. breakdown services).Services includerepair services, maintenanceprocesses,warranty claims andquality assur‐ance measures,forexample. Theread out is per‐formed viathe legally prescribed portforthediagnostics connection inthevehicle. Therespective service network locations orthirdparties collect, process and usethe data. Theydocumenttechnicalstatuses ofthevehicle,assist infinding malfunctions and improvingquality and are transmittedtothe manufacturer,if necessary.Furthermore,the manufacturer issubjecttoproduct liability.Forthis,the manu‐facturerrequirestechnical datafromvehicles.

Vehicle electronics
Two-wayradios
Notes on installing two-wayradios
\nWARNINGRisk of accident duetoimproperworkon two-wayradios
The electromagneticradiation from two-wayradios can interferewiththe on-board elec‐tronics if RF transmittersare manipulated orretrofitted incorrectly.
This could jeopardizethe operating safety ofthevehicle.
You should haveallworkon electricaland electronic components carried outat aqualified specialistworkshop.
\nWARNINGRisk of accident from incor‐rect operation of two-wayradios
Ifyou operate two-wayradios incorrectly inthevehicle,the electromagneticradiationcould interferewiththe on-board electronics,e.g.:
Rifthe two-wayradio is not connectedtoanexterior antenna
Riftheexterior antenna is not correctlymounted or is not of lowreflection
This could jeopardiesthe operating safety ofthevehicle.
Havethe low-reflectionexteriorantenna installed at aqualified special‐istworkshop.
When operating two-wayradios inthevehicle, always connectthemtothelow-reflectionexterior antenna.
NOTEInvalidation ofthe operating per‐mit duetofailuretocomply with theinstructionsfor installation and use
The operating permit may be invalidated ifthe instructionsfor installation and use oftwo-wayradios are not observed.
Only use approved frequency bands.
Observethe maximum permissible out‐put power inthese frequency bands.
Only use approved antenna positions.
