Safety
ActiveCityBrake
ActiveCityBrakeisadrivingassistance
systemthataimstoavoidafrontalcollision
orreducethespeedofanimpactifthedriver
doesnotreactsufficiently(inadequatebrake
application).
Thissystemisdesignedtoimprove
drivingsafety.
Itremainsthedriver'sresponsibilityto
continuouslymonitorthestateofthe
trafficandtoassessthedistancesand
relativespeedsofothervehicles.
ActiveCityBrakecaninno
circumstancesreplacetheneedfor
vigilanceonthepartofthedriver.
Neverlookatthelasersensorthrough
anopticalinstrument(magnifyingglass,
microscope...)atadistanceoflessthan
10centimetres:riskofeyeinjury.
Automaticbrakingoccurslaterthanif
donebythedriver,soastointervene
onlywhenthereisahighriskof
collision.
Principle
Usingalasersensorlocatedatthetopofthe
windscreen,thissystemdetectsavehicle
runninginthesamedirectionorstationary
aheadofyourvehicle.
Whennecessary,thevehicle'sbrakingsystem
isoperatedautomaticallytoavoidacollision
withthevehicleahead.
Conditions for activation
ActiveCityBrakeonlyoperatesifthefollowing
conditionsaremet:
● ignitionon,
● thevehicleisinaforwardgear,
● speedisbetweenabout3and18mph
(5and30km/h),
● thebrakingassistancesystems(ABS,
EBFD,emergencybrakingassistance)are
not faulty,
● thetrajectorycontrolsystems(ASR,DSC)
arenotdeactivatedorfaulty,
● thevehicleisnotinatightcorner,
● thesystemhasnotbeentriggeredduring
theprevious10seconds.
