Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrabilityofyourvehiclewhenbraking
and contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
TheABSpreventswheellockintheeventof
emergencybraking.
TheEBFDmanagesthebrakingpressure
wheelbywheel.
Emergency braking assistance
(EBA)
Inanemergency,thissystemenablesyouto
reachtheoptimumbrakingpressuremore
quicklyandthereforereducethestopping
distance.
Itistriggeredaccordingtothespeedatwhich
thebrakepedalispressed.Thisisfeltbya
reduction in the resistance of the pedal and an
increaseintheeffectivenessofthebraking.
Anti-slip regulation (ASR)
TheASRsystem(alsoknownasTraction
Control) optimises traction in order to limit
wheelslipbyactingonthebrakesofthedriving
wheelsandontheengine.Italsoimproves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automaticallyactsonthebrakeofoneormore
wheelsandontheenginetoreturnthevehicle
to the required path, within the limits of the laws
ofphysics.
