ECO Assistis active only in drive programs;andA.
System limitationsECO Assist can function more precisely iftheroute is maintained whenroute guidance isactive. The basic function is alsoavailable with‐out activeroute guidance.Notall informationand traffic situations can beforeseen. Thequal‐ity depends onthe map data.
ECO Assist is only an aid. The driver isresponsi‐bleforkeeping a safe distance fromthevehiclein front,forvehicle speed andfor braking ingood time. The driver must bereadytobrake atall times irrespective of whetherthe systemintervenes.
The system may be impaired or may not functioninthefollowing situations:
RIfthere is poor visibility, e.g. duetoinsuffi‐cient illumination oftheroad, highlyvariableshade conditions,rain, snow,fog or heavyspray.
RIfthere isglare, e.g. from oncoming traffic,direct sunlight orreflections.
RIfthere is dirt onthe windshield inthe vicin‐ity ofthe multifunction camera orthe cameraisfogged up, damaged or obscured.
RIfthe traffic signs are hardtodetect, e.g. duetodirt or snow or insufficient lighting, orbecausetheyare obscured.
RIfthe information onthe navigation system'sdigital map is incorrect or out of date.
RIfthe signs are ambiguous, e.g. traffic signsinroadworksor in adjacent lanes.

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.
If ABS intervenes when braking,you willfeel apulsing inthe brake pedal. The pulsating brake
pedal can be an indication of hazardousroadconditions and can serveas aremindertotakeextra care while driving.
System limitationsRABS is active from speeds of approx. 5mph(8 km/h).
RABS may be impaired or may not function if amalfunction has occurred andtheyel‐low%ABSwarning lamp lights up contin‐uously inthe instrument cluster aftertheengine isstarted.
Function ofBAS (Brake Assist System)
\nWARNINGRisk of an accident causedbya malfunction inBAS (Brake AssistSys‐tem)
IfBAS is malfunctioning,the braking distancein an emergency braking situation isincreased.
Depressthe brake pedal with fullforcein emergency braking situations. ABSpreventsthe wheels from locking.

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 and distancetothevehicle in front are set and saved onthesteeringwheel onvehicles withoutthe Driving AssistancePackage, intherange between15mph(20 km/h) and120mph (200 km/h) and, on
vehicles withthe Driving AssistancePackage, intherange between15mph (20 km/h) and130mph (210km/h).
Otherfeatures ofActive Distance AssistDISTRONIC:
RAdjuststhe drivingstyle depending ontheselected drive program (fuel-saving, comfort‐able or dynamic) (→page148)

\nWARNINGRisk of accident if detectionfunction ofActive Distance AssistDISTRONIC is impaired
Active Distance AssistDISTRONIC does notreact or has a limitedreaction:
Rwhen driving on a different lane or whenchanging lanes
Rtopedestrians, animals, bicycles orsta‐tionaryvehicles, or unexpected obstacles
Rtocomplextraffic conditions
Rtooncomingvehicles and crossing traffic
As aresult,Active Distance AssistDISTRONIC may neither givewarnings norintervene in suchsituations.
Always observethe traffic conditionscarefully andreact accordingly.
OperatingActive Distance Assist DISTRONIC
Requirements:RThevehicle has beenstarted.
RThe electric parking brake isreleased.
RESP®is activated and is not intervening.
RThe transmission is in position[.
RAllthe doors are closed.
RCheck oftheradar sensor system has beensuccessfully completed (vehicle travelingfasterthan12mph (20 km/h)).
RParking AssistPARKTRONIC is not beingusedtoparkthevehicle ortoexit from aparking space.
RThevehicle does not skid.
Toactivate/deactivateActive DistanceAssist DISTRONIC:press button1.
ToactivateActive Distance AssistDISTRONIC:pressrocker switch3up (SET+) or down (SET-), or pressrocker switch4up.Removeyourfootfromthe acceleratorpedal.The current speed isstored and maintainedbythevehicle.

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
