takeregular breaks in good timethat allowforadequaterecuperation.
You canchoose between two settings.
RStandard:normal system sensitivity.
RSensitive:higher system sensitivity. Thedriver iswarned earlier andthe attentionlevel detectedbyATTENTION ASSIST is adap‐ted accordingly.
If drowsiness or increasing lapses in concentra‐tion are detected,theATTENTION ASSIST: Takea Break!warning appears inthe instrument dis‐play.You can acknowledgethe message andtake a break where necessary.Ifyou do nottakea break andATTENTION ASSIST continuestodetect increasing lapses in concentration,youwill bewarned again after a minimum of15minutes.

Traffic Sign Assist
Function ofTraffic Sign Assist
Traffic Sign Assistdetects traffic signs withmul‐tifunction camera1. It assistsyoubydisplay‐ing detected speed limits andovertakingrestric‐
tions inthe instrument cluster and optionally inthe Head-up Display.
SinceTraffic Sign Assistalso usesthe datastored inthe navigation system, it can updatethe display inthefollowing situations withoutdetecting traffic signs:
RWhenthevehiclechangesroads, e.g. a free‐way entry orexitroad.
RWhen a village or city boundary which isstored inthe digital map is passed.
The camera also detects traffic signs with arestriction indicatedbyan additional sign (e.g. inwet conditions).
Traffic Sign Assistis only an aid. The driver isresponsibleforkeeping a safe distancetothevehicle in front,forvehicle speed andfor brakingin good time. The maximum permissible speedalso depends onfactors suchastheroad sur‐face and traffic conditions.

\nWARNINGRisk of accident despiteActive Blind Spot Assist
Active Blind Spot Assistdoes notreacttothefollowing:
RIfvehiclesovertaketoo closely ontheside, placingthem inthe blind spot area
RVehicles approaching andovertakingyouat agreatly different speed
As aresult,Active Blind Spot Assistmay nei‐ther givewarnings nor intervene in suchsit‐uations.
Always pay careful attentiontothe traf‐fic situation and maintain a safe dis‐tance atthe side ofthevehicle.
If a course-correcting brake application occurs,theredwarning lampflashes inthe outside mir‐ror and awarningtone sounds. In addition, dis‐play1indicatingthe danger of a side collisionappears inthe multifunction display.
Inrarecases,the system may make an inappro‐priate brake application. This brake application
may be interrupted at any time ifyousteerslightly inthe opposite direction or accelerate.
