\nWARNINGRisk 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
Thefollowing function is country-dependentand onlyavailable in conjunction withtheDriving AssistancePackage.
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(page189).
Routeevents ahead are:
RBends
RT-intersections, traffic circles andtollsta‐tions
RTurns andexits
RTraffic jams ahead (only withLiveTraffic(page 293))
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.
18 8Driving and parking

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
RIfthe setroute isre-planned
RInroad construction areas
RWhentowing a trailer
RIn badweather orroad conditions

System limitationsObjects located aboveor belowthe detectionrange ofActiveParking Assist are not detectedwhenthe parking space is being measured.These are also nottaken into account whentheparking maneuver is calculated, e.g.overhangingloads,overhangs or loadingramps of trucksorthe boundaries of parking spaces. In some cir‐cumstances,ActiveParking Assist maythereforeguideyou intothe parking space prematurely.
\nWARNINGRisk of accident duetoobjects located aboveor belowthedetectionrange ofActiveParking Assist
Ifthere are objects aboveor belowthedetectionrange,thefollowing situations mayarise:
RActiveParking Assist maysteertoo early.
RVehicles with automatic transmis‐sion:Thevehicle may notstop in front ofthese objects.
This could cause a collision.
Inthese situations, do not useActiveParking Assist.
Snowfall or heavyrain may leadtoa parkingspace being measured inaccurately.Parkingspacesthat are partiallyoccupiedbytrailerdrawbars might not be identified as such or bemeasured incorrectly. Only useActiveParkingAssist on level, high-gripground.
