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.

cruise control willresume speedregulation backtothestored speed.
Cruise control is operated usingthe correspond‐ingsteering wheel buttons.You canstore anyspeed above15mph (20 km/h) uptothe maxi‐mum speed.
Ifyoufailtoadaptyour drivingstyle, cruise con‐trol can neitherreducetherisk of an accidentnoroverridethe lawsof physics. It cannottakeinto accountroad,weather or traffic conditions.Cruise control is only an aid.You areresponsibleforthe distancetothevehicle in front,forvehi‐cle speed,for braking in good time andforstay‐ing inyour lane.
Displaysonthe multifunction displayThestatus of cruise control andthestoredspeed are shown inthe multifunction display.

2Speed is saved, cruise control is deactivated
3Speed is saved, cruise control is activated
%The segments betweenthestored speed andthe end ofthe segment display light up inthe speedometer.
System limitationsCruise control may be unabletomaintainthestored speed on uphill gradients. Thestoredspeed isresumed whenthe gradientevens out.
Change into a lowergear in good time on longandsteep downhill gradients.Takeparticularnoteofthis when driving a ladenvehicle. By
doing so,you will make use ofthe engine's brak‐ing effect. Thisrelievesthe load onthe brakesystem and preventsthe brakes fromoverheat‐ing andwearingtooquickly.
Do not use cruise control inthefollowing situa‐tions:
RIn traffic situations whichrequire frequentchanges of speed, e.g. in heavy traffic, onwindingroads.
ROn slipperyroads.Accelerating can causethe drive wheelstolose traction andthevehicle couldthen skid.
RIfyou are driving when visibility is poor.
