turally 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.
\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.
Always carefully observethe traffic con‐ditions and bereadytobrake at alltimes.
Takeinto accountthe traffic situationbefore calling upthestored speed.
\nWARNINGRisk of accident duetoinsuf‐ficient decelerationbyActive DistanceAssistDISTRONIC
Active Distance AssistDISTRONIC brakesyourvehicle with upto50% ofthe maximumpossible deceleration. Ifthis deceleration isnot sufficient,Active Distance AssistDISTRONIC alertsyou with a visual andacousticwarning.
Inthese cases, adjustyour speed andkeep a sufficient distance.

17 8Driving and parking

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
