and PRE-SAFE ®
Brak edetects arisk of acol-

visually and acoustically. If you do not brake
or steer ,the vehicle will at first automatically
brake slightly. In the event of an increased
risk of acollision, PRE-SAFE ®
is activated
(Y page 40). If the risk of collision persist sand
you do not brake, manoeuvr eoraccelerate

application may be carried out. G
Risk of accident
Only clearly detected obstacles will trigger a
warning and initiat ebrakin gassistance by
PRE-SAFE ®
Brake.
In particular, the detection of obstacles can
be impaired if ther eis:
R dirt on the sensors or the sensors are cov-

R snow or heavy rain
R interferenc ebyother radar sources
R the possibility of strong radar reflections,
for example in multi-storey car parks

Risk of accident
Depending on the curren tspeed, PRE-SAFE ®
Brak edecelerates your vehicle by up to
4m /s2
before performing possible emer-
genc ybraking. This is equivalent to approx-
imately 40 %ofthe maximum brakin gpower
of the vehicle. You must additionally apply the
brakes yourself in order to preven tacollision

prior to an acciden tinthe event that you are
unable to avoid one by, for instance, taking
evasive action. In order to maintain the appropriate distance
to the vehicle in fron

At speeds up to approximately 70 km/h,
PRE-SAFE ®
