extended period of time.
In addition, pedestrians in the path of your vehi-
cle can be detected.

WARNING
®
PRE-SAFE
Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-
ularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so.
In the event of a partial application of the brakes,
the vehicle is braked with up to 50% of the full
braking pressure.

strong radar reflections, for example, in multi-
R
storey car parks
a narrow vehicle travelling in front, e.g. a
