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 brakepedal 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)
&WARNINGRisk of an accident causedbya malfunction inBAS (Brake AssistSys‐tem)
IfBAS is malfunctioning,the braking distancein an emergency braking situation isincreased.

System limitationsTemporary speedrestrictions (e.g.for a certaintime or duetoweather conditions) cannot beproperlydetectedbythe system. The maximumpermissible speed applyingfor avehicle with atrailer is not detectedbythe system. Inthese sit‐uationsyou must adjustyour speedyourself.
&WARNINGRisk 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
%Theavailability ofthefollowing function iscountry-dependent.
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 (→page 208).
Routeevents ahead are:
RBends
RT-intersections, traffic circles andtollsta‐tions
RTurns andexits
%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.
