tow MERCEDES-BENZ C CLASS 2019 Workshop Manual

ROnly increasethe engine speed gradually andacceleratethevehicletofull speed after1,000 miles (1,500 km).
This also applies whenthe engine or parts ofthedrivetrain havebeenreplaced.
Please also observethefollowing breaking-innotes:
RIn certain driving and driving safety systems,the sensors adjust automatically while a cer‐tain distance is being driven afterthevehiclehas been delivered or afterrepairs.Full sys‐tem effectiveness is notreached untiltheend ofthisteach-in process.
RBrakepads, brake discs and tiresthat areeither new or havebeenreplaced only ach‐ieveoptimum braking effect and grip afterseveral hundred kilometers of driving. Com‐pensateforthereduced braking effectbyapplyinggreaterforcetothe brake pedal.
Notes on driving
\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.
\nWARNINGRisk of accident duetounsuitablefootwear
Operation ofthe pedals may berestrictedduetounsuitablefootwear such as:
RShoes with platformsoles
RShoes with high heels
RSlippers
When driving alwayswear suitableshoes in ordertobe abletooperatethepedals safely.
\nWARNINGRisk of accident when switch‐ing offthe ignition when driving
Ifyou switchoffthe ignition while driving,safety functions arerestricted or no longeravailable. This may affectthe powersteeringsystem andthe brakeforce boosting,forexample.
You willthen needtouse considerably moreforcetosteer and brake.

Function ofActive Speed Limit Assist
If achange inthe speed limit is detected andActive Distance AssistDISTRONIC is activated,Active Distance AssistDISTRONIC adaptsthisnew speed asthestored speed.
The driven speed is adjusted whenthevehicle islevel withthe traffic sign atthe latest. Inthecase of signs indicating entry into an urban area,the speed is adapted accordingtothe speed
permitted withinthe urban area. The speed limitdisplay inthe instrument display is always upda‐ted whenthevehicle is level withthe traffic sign.
Ifthere is no speedrestriction on an unlimitedstretch ofroad (e.g. on a freeway),therecom‐mended speed is adopted asthestored speed.The system usesthe speedstored on an unlimi‐tedstretch ofroad astherecommended speed.Ifyou do not alterthestored speed on an unlimi‐tedstretch ofroad,therecommended speed is80mph (130 km/h).
IfActive Distance AssistDISTRONIC has beenput into passivemodebypressingthe accelera‐tor pedal, only speed limits whichare higherthanthe set speed are adopted.
Active Speed Limit Assistis only an aid. Thedriver isresponsibleforkeeping a safe distancetothevehicle in front,forvehicle speed andforbraking in good time. The maximum permissiblespeed also depends onfactors suchastheroadsurface and traffic conditions.
System limitationsTemporary speedrestrictions (e.g.for a certaintime or duetoweather conditions) cannot be

properlydetectedbythe system. The maximumpermissible speed applyingfor avehicle with atrailer is not detectedbythe system. Inthese sit‐uationsyou must adjustyour speedyourself.
\nWARNINGRisk of accident duetoActiveSpeed Limit Assistadaptingthevehicle'sspeed
The speed adoptedbyActive Speed LimitAssistmay betoo high or incorrect in someindividual cases, suchas:
RInthewet or infog
RWhentowing a trailer
Ensurethatthe driven speed complieswith trafficregulations.
Adjustthe driving speedtosuit currenttraffic andweather conditions.
Function ofroute-based speed adaptation
Thefollowing function is country-dependentand onlyavailable in conjunction withtheDriving AssistancePackage.
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(page189).
Routeevents ahead are:
RBends
RT-intersections, traffic circles andtollsta‐tions
RTurns andexits
RTraffic jams ahead (only withLiveTraffic(page 293))
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.
18 8Driving and parking

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
RIfthe setroute isre-planned
RInroad construction areas
RWhentowing a trailer
RIn badweather orroad conditions

If novehicle is detected inthe adjacent lane anda lanechange is permitted,the lanechangebegins. This is showntothe driver with a greenarrow2nexttothesteering wheel symbol.TheLane Change to the Leftmessage alsoappears,forexample. IfActive Lane ChangeAssisthas been activated withthe turn signalindicator but a lanechange is not immediatelypossible, a grayarrow1appears nexttothesteering wheel symbol, whichremains green.
Whenthe lanechange assistancestarts,the turnsignal indicator is automatically activated besidethe display inthe multifunction display.
Ifthe assistance graphic is shown whenchang‐ing lanes,the lanechange display appears with
an additional arrowpointingtowardsthe adja‐cent lane (page193).
If a lanechange is not possible,the arrow fadesout after afew seconds and a new lanechangemust be initiated. An immediate lanechange isonly possible on freeway sections without speedlimits.
Ifthe system is impaired,Active Lane ChangeAssistmay be canceled. If it is canceled,theLane Change Canceledmessage appears inthemultifunction display and awarningtone sounds.
\nWARNINGRisk of accident fromchang‐ing lanetoan occupied adjacent lane
Lane ChangeAssistcannot alwaysdetectclearly ifthe adjacent lane is free.
The lanechange might be initiated althoughthe adjacent lane is not free.
Beforechanging lanes, make surethatthe neighboring lane is free andthere isno dangerto otherroad users.
Monitorthe lanechange.
\nWARNINGRisk of accident if LaneChange Assistunexpectedlystops func‐tioning
