Due to the nature of the system ,particularly

If yo ufailtoa dapt your driving style ,Adaptive
Brake Assist can neither reduce the ris kofacci-

Brake Assist canno ttake into account road,

Operation
With the hel pofthe rada rsensor system ,Adap-
tive Brake Assist can detect obstacle sthath ave
been in the path of your vehicl efor an extended
perio doft ime.Adaptive Brake Assist does not
react to stationar yobstacles. If Adaptive Brake Assist detects
ariskofc ollision with avehicle
traveling in front or with astationar yobstacle,
the system calculate sthe braking forc eneces-
sary to avoidt hiscollision. If yo uapply the
brakes forcefully, Adaptive Brake Assist will
automaticall yincrease the braking forc etoa
level suitabl efor the traffic conditions.
