Function oftheradar sensors
Some driving and driving safety systems useradar sensorstomonitorthe area in front of,behind or nexttothevehicle (depending onthevehicle's equipment).
Depending onthevehicle's equipment,theradarsensors are integrated behindthe bumpersand/or behindthe Mercedesstar.Keeptheseparts free of dirt, ice and slush(page 364). The sensors must not be cov‐ered,forexamplebycycleracks,overhangingloads,stickers,foil orfoilstoprotect againststonechipping. Intheevent of damagetothebumpers orradiator grill, orfollowing a collisionimpactingthe bumpers orradiator grill, havethefunction oftheradar sensorschecked at aquali‐fied specialistworkshop. The driver assistancesystem may no longerworkproperly.

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.
Driving and parking171

1Cruise control is selected
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.
Operating cruise control
\nWARNINGRisk of accident duetostoredspeed
Ifyou call upthestored speed andthis islowerthanyour current speed,thevehicledecelerates.
Takeinto accountthe traffic situationbefore calling upthestored speed.
Requirements:RESP®must be activated, but not intervening.
RThe driven speed is at least15mph(20 km/h).
RThe transmission is in position[.
Toactivate cruise control:pressrockerswitch1up.

Otherfeatures ofActive Distance AssistDISTRONIC:
RAdjuststhe drivingstyle depending ontheselected drive program (fuel-saving, comfort‐able or dynamic) (page153)
RVehicles with Driving AssistancePack‐age:reactstostationaryvehicles detected inurban speedranges (except bicycles andmotorcycles).
RInitiates accelerationtothestored speed ifthe turn signal indicator is switched ontochangetotheovertaking lane.
RVehicles with Driving AssistancePack‐age:takes one-sidedovertakingrestrictionsinto account on highways or on multi-laneroads with separateroadways (country-dependent).
Vehicles withActiveParking Assist and Driv‐ing AssistancePackage:ifthevehicle hasbeen brakedtoastandstill on multi-lane,struc‐
turallyseparateroadwaysbyActive 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 ingreatlyvaryingambient 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.
\nWARNINGRisk of accident from acceler‐ation or brakingbyActive DistanceAssistDISTRONIC
Active Distance AssistDISTRONIC may accel‐erate or brake inthefollowing cases,forexample:
RIfthevehicle pullsawayusingActive Dis‐tance AssistDISTRONIC.
RIfthestored speed is called up and isconsiderablyfaster or slowerthanthecurrently driven speed.
RIfActive Distance AssistDISTRONIC nolonger detects avehicle in front or doesnotreacttorelevant objects.
