yourvehicle'sspeedatavaluethatyou
havedefined,theinter-vehicletimeyouhave
selectedbetweenyourvehicleandtheone

Principles of operation
Usingaradarwitharangeofabout100metres,
locatedatthefrontofthevehicle,thissystem
detectsavehiclerunninginfrontofyour
vehicle.
Itautomaticallyadaptsthespeedofthevehicle
tothatofthevehicleinfront.
Ifthevehicleinfrontisrunningmoreslowly,
thesystemprogressivelyreducesthespeedof
yourvehicleusingjustenginebraking(asifthe
driverhadpressedthe"-"button).
Ifyourvehicleistooclosetoorapproaching
tooquicklythevehicleinfront,thecruise
controlisautomaticallydeactivated.The
driveristhenalertedbyanaudiblesignal,
accompaniedbyamessage.
Ifthevehicleinfrontacceleratesorchanges
lane,theactivecruisecontrolprogressively
accelerates your vehicle to return to the
programmedspeed.
Ifthedriveroperatesadirectionindicatorto
theleft(lefthanddrive)ortheright(righthand
drive),toovertakeaslowervehicle,theactive
cruisecontrolallowsyourvehicletotemporarily
approach the vehicle in front to assist the
overtakingmanoeuvre,thoughneverexceeding
theprogrammedspeed.
The active cruise control operates by
dayandatnight,infogorinmoderate
rainfall.
Thesystemdoesnotactonthebraking
system,butworksonlywithenginebraking.
Theregulationrangeislimited:therewill
nolongerbeanyadjustmentofspeedifthe
differencebetweentheprogrammedspeed
settingandthespeedofthevehicleinfront
becomestoohigh(18mph(30km/h)).
Theselectionofthissystemdeactivates
theinter-vehicletimefunction.
Ifthedifferencebetweenthe
programmedspeedsettingandthe
speedofthevehicleinfrontistoo
great,thespeedcannotbeadjusted:
thecruisecontrolisautomatically
deactivated.
