If achange inthe speed limit is detected andActive Distance AssistDISTRONIC is activated,Active Distance AssistDISTRONIC adaptsthisnew speed asthestored speed.
The driven speed is adjusted whenthevehicle islevel withthe traffic sign atthe latest. Inthecase of signs indicating entry into an urban area,the speed is adapted accordingtothe speedpermitted withinthe urban area. The speed limit
display inthe instrument display is always upda‐ted whenthevehicle is level withthe traffic sign.
Ifthere is no speedrestriction on an unlimitedstretch ofroad (e.g. on a freeway),therecom‐mended speed is adopted asthestored speed.The system usesthe speedstored on an unlimi‐tedstretch ofroad astherecommended speed.Ifyou do not alterthestored speed on an unlimi‐tedstretch ofroad,therecommended speed is80mph (130 km/h).
IfActive Distance AssistDISTRONIC has beenput into passivemodebypressingthe accelera‐tor pedal, only speed limits whichare higherthanthe set speed are adopted.
Active Speed Limit Assistis only an aid. Thedriver isresponsibleforkeeping a safe distancetothevehicle in front,forvehicle speed andforbraking in good time. The maximum permissiblespeed also depends onfactors suchastheroadsurface and traffic conditions.
System limitationsTemporary speedrestrictions (e.g.for a certaintime or duetoweather conditions) cannot beproperly detectedbythe system. The maximum
permissible speed applyingfor avehicle with atrailer is not detectedbythe system. Inthese sit‐uationsyou must adjustyour speedyourself.
\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.

HOLD function
HOLD functionThe HOLD function holdsthevehicle at astand‐still withoutrequiringyoutodepressthe brakepedal, e.g. whilewaiting in traffic.
The HOLD function is only an aid. Theresponsi‐bilityforthevehicle safelystandingstillremainswiththe driver.
System limitationsThe HOLD function is only intendedtoprovideassistance when driving and is not a sufficientmeans of safeguardingthevehicle againstrollingawaywhenstationary.
RThe incline must not be greaterthan 30%.
Activating/deactivating the HOLD function
\nWARNINGRisk of an accident duetotheHOLD function being activated whenyouleavethevehicle
Ifyou leavethevehicle while onlythe HOLDfunction is brakingthevehicle,thevehiclecanrollawayinthefollowing situations:
RIfthere is a malfunction inthe system orinthe power supply.
RIfthe HOLD function is deactivatedbydepressingthe accelerator pedal orthebrake pedal, e.g.byavehicle occupant.
RIfthe electrics inthe engine compart‐ment,the battery orthe fuses aretam‐pered with or ifthe battery is disconnec‐ted.
Always deactivatethe HOLD functionand securethevehicle againstrollingawaybefore leavingthevehicle.
NOTEDamagefrom automatic braking
WhenActive Brake Assist,Active DistanceAssistDISTRONIC orthe HOLD function areactivated,thevehicle brakes autonomouslyin certain situations.
Toavoid damagetothevehicle, deactivatethese systems inthefollowing or similar sit‐uations:
