Accesstothevehicle and/orthe EDR is neededtoread datathat isrecordedbythe EDR, andspecial equipment isrequired. In additiontothevehicle manufacturer,other partiesthat havethespecial equipment, such as law enforcement,canreadthe informationbyaccessingthevehi‐cle orthe EDR.
EDR data may be used in civil and criminal mat‐tersas atool in accidentreconstruction, acci‐dent claims andvehicle safety.Sincethe CrashDataRetrieval (CDR)toolthat is usedtoextractdatafromthe EDR is commerciallyavailable,Mercedes-Benz USA,LLC ("MBUSA")expresslydisclaims any and all liability arising fromtheextraction ofthis informationbyunauthorizedMercedes-Benz personnel.
MBUSA will not share EDR data withothers with‐outthe consent ofthevehicleowner or, ifthevehicle is leased, withoutthe consent ofthe les‐see. Exceptionstothisrepresentation includeresponsestosubpoenasbylaw enforcement;byfederal,state or local government; in connectionwith or arising out of litigation involving MBUSAor its subsidiaries and affiliates; or, asrequiredbylaw.
Warning:the EDR is a component oftheRestraint System Module.Tampering with, alter‐ing, modifying orremovingthe EDR componentmayresult in a malfunction oftheRestraint Sys‐tem Module andother systems.
State lawsorregulationsregarding EDRsthatconflict withfederalregulation are pre-empted.This meansthat intheevent of such conflict,thefederalregulation governs. As of December2016,17states haveenacted lawsrelatingtoEDRs.

Function of ABS (Anti-lock Braking System)
ABSregulatesthe brake pressure in critical driv‐ing situations:
RDuring braking, e.g. at full brake applicationor insufficient tire traction,the wheels areprevented from locking.
RVehiclesteerability while braking is ensured.
If ABS intervenes when braking,you willfeel apulsing inthe brake pedal. The pulsating brakepedal can be an indication of hazardousroadconditions and can serveas aremindertotakeextra care while driving.
System limitationsRABS is active from speeds of approx. 5mph(8 km/h).
RABS may be impaired or may not function if amalfunction has occurred andtheyel‐low%ABSwarning lamp lights up contin‐uously inthe instrument cluster aftertheengine isstarted.
Function ofBAS (Brake Assist System)
&WARNINGRisk of an accident causedbya malfunction inBAS (Brake AssistSys‐tem)
IfBAS is malfunctioning,the braking distancein an emergency braking situation isincreased.

Cruise control is operated usingthe correspond‐ingsteering wheel buttons.You canstore anyspeed above15mph (20 km/h) uptothe maxi‐mum speed.
Ifyoufailtoadaptyour drivingstyle, cruise con‐trol can neitherreducetherisk of an accidentnoroverridethe lawsof physics. It cannottakeinto accountroad,weather or traffic conditions.Cruise control is only an aid.You areresponsibleforthe distancetothevehicle in front,forvehi‐cle speed,for braking in good time andforstay‐ing inyour lane.

2Speed is saved, cruise control is deactivated
3Speed is saved, cruise control is activated
%The segments betweenthestored speed andthe end ofthe segment display light up inthe speedometer.
System limitationsCruise control may be unabletomaintainthestored speed on uphill gradients. Thestoredspeed isresumed whenthe gradientevens out.
Change into a lowergear in good time on longandsteep downhill gradients.Takeparticularnoteofthis when driving a ladenvehicle. By
doing so,you will make use ofthe engine's brak‐ing effect. Thisrelievesthe load onthe brakesystem and preventsthe brakes fromoverheat‐ing andwearingtooquickly.
Do not use cruise control inthefollowing situa‐tions:
RIn traffic situations whichrequire frequentchanges of speed, e.g. in heavy traffic, onwindingroads.
ROn slipperyroads.Accelerating can causethe drive wheelstolose traction andthevehicle couldthen skid.
RIfyou are driving when visibility is poor.

Active Distance Assist DISTRONIC
Function ofActive Distance AssistDISTRONIC
Active Distance AssistDISTRONIC maintainstheset speed on free-flowingroads. Ifvehicles infront are detected,the set distance is main‐tained, if necessary,untilthevehicle comesto ahalt. Thevehicle accelerates or brakes depend‐ing onthe distancetothevehicle in front andthe set speed. The speed (intherange between15mph (20 km/h) and130mph (210km/h))andthe distancetothevehicle in front are setand saved onthesteering wheel.
Otherfeatures ofActive Distance AssistDISTRONIC:
RAdjuststhe drivingstyle depending ontheselected drive program (fuel-saving, comfort‐able or dynamic) (→page175)
RReactstostationaryvehicles detected inurban speedranges (except bicycles andmotorcycles)
RInitiates accelerationtothestored speed ifthe turn signal indicator is switched ontochangetotheovertaking lane.
RTakes one-sidedovertakingrestrictions intoaccount on highways or on multi-laneroadswith separateroadways (country-dependent).
Vehicles withActiveParking Assist:ifthevehicle has been brakedtoastandstill on multi-lane, separateroadwaysbyActive DistanceAssistDISTRONIC, it can automaticallyfollowthevehicle in front driving off again within30 seconds. If a critical situation is detectedwhen driving off, a visual and acousticwarning isgiven indicatingthatthe driver must nowtakecontrol ofthevehicle. Thevehicle is not acceler‐ated any further.
Active Distance AssistDISTRONIC is only an aid.The driver isresponsibleforkeeping a safe dis‐tancetothevehicle in front,forvehicle speedandfor braking in good time.
System limitations
The system may be impaired or may not functioninthefollowing instances:
RIn snow,rain,fog, heavy spray, ifthere isglare, in direct sunlight or in greatlyvaryingambient light.
RThe windshield inthe area ofthe camera isdirty,fogged up, damaged or covered.
RIftheradar sensors are dirty or covered.
RIn parkinggarages or onroads withsteepuphill or downhill gradients.
RIfthere are narrowvehicles in front, such asbicycles or motorcycles.
In addition, on slipperyroads, braking or accel‐erating can cause one or several wheelstolosetraction andthevehicle couldthen skid.
Do not useActive Distance AssistDISTRONIC inthese situations.
