ing speed ranges:
R4-1 24 mph (7 -200 km/h )for moving
objects
R4-31m ph (7-50km/h)for stationary
objects
Due to the nature of the system, particularly

Adaptive Brake Assist
General information
iObserve the "Important safety notes "sec-
tion (Ypage 61).
With the hel pofadaptive Brake Assist, the dis-
tance warning signal can detect obstacles that
are in the path of your vehicl efor an extended
perio doft ime.
If adaptive Brake Assist detects ariskofc olli-
sio nw itht he vehicl einfront, it calculate sthe
braking force necessary to avoid acollision. If
yo ua pply the brakes forcefully ,adapt ive Brake
Assist will automaticall yincreas ethe braking
force to alev el suitabl efor the traffic conditions.
Adaptive Brake Assist provides braking assis-
tance in hazardouss ituations at speeds above
4m ph (7 km/h). It uses radar sensor technology
to asses sthe traffic situation.
Up to aspeed of approximately 155 mph
(250 km/h), adaptive Brake Assist is capable of
reacting to moving objects that have already
bee ndetected as such at leas tonce ove rthe
perio dofo bservation.
Up to aspeed of approximately 44 mph
(70 km/h),a daptive Brake Assist reacts to sta-
tionary obstacles.
If adaptive Brake Assist demand sparticularly
hig hb raking force ,preventative passenger pro-
tectio nmeasures (PRE-SAFE
®)are activated
simultaneously (Ypage 55).
