\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

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 and distancetothevehicle in front are set and saved onthesteeringwheel onvehicles withoutthe Driving AssistancePackage, intherange between15mph(20 km/h) and120mph (200 km/h) and, on
vehicles withthe Driving AssistancePackage, intherange between15mph (20 km/h) and130mph (210km/h).
Otherfeatures ofActive Distance AssistDISTRONIC:
RAdjuststhe drivingstyle depending ontheselected drive program (fuel-saving, comfort‐able or dynamic) (→page148)
RVehicles with Driving AssistancePack‐age:reactstostationaryvehicles detected inurban speedranges (except bicycles andmotorcycles).

When Distance AssistDISTRONIC is active,thefunction adjuststhe speed depending ontherouteevents ahead. Depending onthe drive pro‐gram selected,thevehicle negotiatestherouteevent ahead in a fuel-saving, comfortable ordynamic manner. Whentherouteevent has beenpassed,thevehicle accelerates againtothestored speed. The set distancetothevehicle infront,vehicles detected ahead and speedrestric‐tions ahead aretaken into account.
Route-based speed adjustment canbyconfig‐ured inthe multimedia system (→page183).
Routeevents ahead are:
RBends
RT-intersections, traffic circles andtollsta‐tions
RTurns andexits
RTraffic jams ahead (only withLiveTraffic(→page 287))
Whenthetollstation isreached,Active Dis‐tance AssistDISTRONIC adoptsthe speed asthestored speed.
Also,the speed isreduced ifthe turn signaltochange lanes is switched on and one ofthefol‐lowing situations is detected:
RTurning off at intersections
RDriving on slowing-down lanes
RDriving on lanes adjacenttoslowing-downlanes
The driver isresponsibleforchoosingtherightspeed and observingotherroad users. Thisapplies in particulartointersections, traffic cir‐cles and traffic lights, asroute-based speedadaptation does not brakethevehicletoastand‐still.
Whenroute guidance is active,thefirst speedadjustment is carried out automatically.Iftheturn signal indicator is switched on,the selectedroute is confirmed and further speed adjustmentis activated.
Speed adjustment is canceled inthefollowingcases:
RIfthe turn signal indicator is switched offbeforetherouteevent.
RIfthe driver depressesthe accelerator orbrake pedal duringthe process.
System limitationsRoute-based speed adaptation does nottakeright ofwayregulations into account. The driverisresponsiblefor complying withroad trafficregulations and driving at a suitable speed.
In difficult conditions (e.g. unclearroads, narrowlanes,wetroad surfaces, snow or ice) or whendriving witha trailer,the speed adjustment madebythe system may not always be suitable. Inthese situationsthe driver must interveneaccordingly.
\nWARNINGRisk of accident in spiteofroute-based speed adjustment
Route-based speed adjustment might mal‐function or betemporarily unavailable inthefollowing situations:
RIf map data is not uptodate oravailable
RIfyou do notfollowthe selectedrouteguidance

Ifthe driver does notsteerthevehicleover along period, or has nottaken hold ofthesteeringwheel, arepeatedwarningtone sounds in addi‐tiontothe visualwarning message (dependingonthe country).
Thewarning message does not appear or disap‐pears if one ofthefollowing conditions are met:
RThe driversteersthevehicle.
RThe driver presses asteering wheel button oroperatesTouch Control.
ActiveSteering Assist is only an aid. The driver isresponsibleforthe distancetothevehicle infront,forvehicle speed,for braking in good timeandforstaying in lane. Beforechanging lanes,the driver must make surethatthe neighboringlane is free (glanceoverthe shoulder).
System limitationsActiveSteering Assist has a limitedsteeringtor‐quefor lateral guidance. In some cases,thesteering intervention is not sufficienttokeepthevehicle inthe lane ortodrive pastexits.
The system may be impaired or may not functioninthefollowing instances:
RIn snow,rain,fog, heavy spray, ifthere isglare, direct sunlight,greatlyvarying ambientlight,reflections orstrong shadowsontheroadway.
RInsufficientroad illumination.
RThe windshield inthe area ofthe camera isdirty,fogged up, damaged or covered.
RAbsence of lane markings, or several unclearlane markings, or ifthe markingschangerap‐idly.
RThe distancetothevehicle in front istoosmall andthe lane markingsthus cannot bedetected.
RTheroad is narrow and winding.
RObstacles onthe lane or projecting out intothe lane.
The system does not provide assistance inthefollowing conditions:
ROn tight bends, intersections,tollstations,traffic circles and when turning.
RWhen activelychanging lane without switch‐ing onthe turn signal.
RWhenthe tire pressure istoo low.
\nWARNINGRisk of accident ifActiveSteering Assist unexpectedlystops func‐tioning
Ifthe system limitations ofActiveSteeringAssist arereachedthere is no guaranteethatthe system willremain active or willkeepthevehicle in lane.
Alwayskeepyour hands onthesteeringwheel and observethe traffic carefully.
Alwayssteerthevehicle paying atten‐tiontotraffic conditions.
\nWARNINGRisk of accident ifActiveSteering Assist unexpectedly intervenes
A malfunction inthe detection of lane mark‐ings and objects can occur.
This could cause unexpectedsteering inter‐vention.

Assistance whenchanging lanes is provided if allthefollowing conditions are met:
RYou are driving on a freeway orroad withmultiple lanes inthe direction of travel.
RThe neighboring lane is separatedbya bro‐ken lane marking.
RNovehicle is detected inthe adjacent lane.
RThe driven speed is between 50mph(80 km/h) and110mph (180 km/h).
