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.
