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.

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.

System limitationsTemporary speedrestrictions (e.g.for a certaintime or duetoweather conditions) cannot beproperlydetectedbythe system. The maximumpermissible speed applyingfor avehicle with atrailer is not detectedbythe system. Inthese sit‐uationsyou must adjustyour speedyourself.
&WARNINGRisk 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
%Theavailability ofthefollowing function iscountry-dependent.
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 (→page 208).
Routeevents ahead are:
RBends
RT-intersections, traffic circles andtollsta‐tions
RTurns andexits
%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:
