20General notes

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.
Fault memories inthevehicle can beresetby aservice outlet as part ofrepair or maintenancework.
Depending onthe selected equipment,you canimport data intothevehicle's comfort and info‐tainment functionsyourself.
This includes,forexample:
Rmultimedia data such as music,films or pho‐tosfor playbackin an integrated multimediasystem
Raddress book datafor use in connection withan integrated hands-free system or an inte‐grated navigation system
Rentered navigation destinations
Rdata aboutthe use of Internet services
This data can be saved locally inthevehicle or itis located on a device whichyou haveconnectedtothevehicle (e.g. smartphone, USBflash driveor MP3 player). Ifthis data isstored inthevehi‐cle,you can deleteit at any time. This data issenttothird parties only atyourrequest, partic‐ularlywhenyou use online services in accord‐ance withthe settingsthatyou haveselected.
General notes27

Restraint system functionality
Whenthe ignition is switched on, a self-test isperformed, during whichtheurestraint sys‐temwarning lamp lights up. It goes out no laterthan afew seconds afterthevehicle isstarted.The components oftherestraint system arethenfunctional.
Malfunctioningrestraint system
A malfunction has occurred intherestraint sys‐tem if:
Rtheurestraint systemwarning lamp doesnot light up whenthe ignition is switched on
Rtheurestraint systemwarning lamplights up continuously orrepeatedly during ajourney
\nWARNINGRisk of injuryorfatal injuryduetoa malfunction intherestraint sys‐tem
Iftherestraint system is malfunctioning,restraint system components may be trig‐
gered unintentionally or might not be trig‐gered at all intheevent of an accident. Thismay affectthe EmergencyTensioning Deviceor airbag,forexample.
Havetherestraint systemchecked andrepaired immediately at aqualified spe‐cialistworkshop.
Function oftherestraint system in an acci‐dent
Howtherestraint systemworks is determinedbythe severity ofthe impact detected andthe typeof accident anticipated:
RFrontal impact
RRear impact
RSide impact
RRollover
The activationthresholdsforthe components oftherestraint system are determined based ontheevaluation ofthe sensorvalues measured atvarious points inthevehicle. This process is pre-emptive in nature. The triggering/deployment of
the components oftherestraint system musttakeplace in good time atthestart ofthe colli‐sion.
Factors whichcan only be seen and measuredafter a collision has occurred do not play a deci‐siverole inthe deployment of an airbag.Nordotheyprovide an indication of airbag deployment.
Thevehicle may be deformed significantly with‐out an airbag being deployed. This isthe case ifonly parts which arerelatively easily deformedare affected andtherateofvehicle decelerationis not high. Conversely, an airbag may bedeployedeventhoughthevehicle suffersonlyminor deformation. Ifveryrigidvehicle partssuch as longitudinal members are hit,forexam‐ple,this mayresult in sufficiently high levels ofvehicle deceleration.

\nWARNINGRisk of injuryduetomodifi‐cationstothe airbag cover
Ifyou modifythe cover of an airbag or affixobjects such asstickerstoit,the airbag mayno longer function correctly.
Never modifythe cover of an airbag anddo not affix objectstoit.
The installation location of an airbag is identifiedbythe AIRBAGsymbol (→page 39).
\nWARNINGRisk of injuryor death duetothe use of unsuitable seat covers
Unsuitable seat coverscan obstruct or pre‐ventthe deployment of air bags integratedintothe seats.
Consequently,the air bags cannotprotectvehicle occupants astheyare designedtodo. In addition, operation ofthe automaticfront passenger air bag shutoff may berestricted.
You should onlyuse seat coversthathavebeen approvedforthe correspond‐ing seatsbyMercedes-Benz.

Cornering light
Cornering light function
The cornering light improvesthe illumination oftheroadwayover a wide angle inthe turningdirection, enabling better visibility on tightbends,forexample. It can be activated onlywhenthe low beam is switched on.
The function is active:
RAtspeeds below 25mph (40 km/h) whenthe turn signal light is switched on orthesteering wheel is turned
RAtspeeds between 25mph (40 km/h) and45mph (70 km/h) whenthesteering wheelis turned

\nWARNINGRisk of accident despiteAdaptive Highbeam Assist
Adaptive Highbeam Assist does notrecog‐nizethefollowingroad users:
RRoad users without lights, e.g. pedes‐trians
RRoad users with poor lighting, e.g.cyclists
RRoad users whose lighting is obstructed,e.g.bya barrier
Onveryrareoccasions,Adaptive HighbeamAssist mayfailtorecognizeotherroad userswiththeirown lighting, or mayrecognizethemtoo late.
Inthese or similar situations,the automatichigh beam is not deactivated or is activateddespitethe presence ofotherroad users.
Always observethe traffic carefully andswitch offthe high beam in good time.
Adaptive Highbeam Assist cannottakeintoaccountroad,weather or traffic conditions.
Detection may berestricted inthefollowingcases:
Rin poor visibility,e.g.fog, heavyrain or snow
Rifthere is dirt onthe sensors orthe sensorsare obscured
Adaptive Highbeam Assist is onlyan aid.You areresponsiblefor adjustingthevehicle's lightingtothe prevailing light, visibility and traffic condi‐tions.
