PRE-SAFE
®
Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE
®
Brake may:
R
give an unnecessary warning and then
brake the vehicle
R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE

Brake warns you. Terminate the
intervention in a non-critical driving situation.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of strong radar reflections,
for example in parking garages

Brake does not react:
R
to people or animals

give warnings nor intervene in all critical
situations. There is a risk of an accident.
