Principle
In

General
Active
Protection
consists
of
different
PreCrash functions
which
may
vary
depending
on
the
equipment
installed.
The
system
detects
critical
driving
situations which
could
potentially
lead
to
an
accident.
Such
situations
include:'xFull
braking.'xSevere
understeer.'xSevere
oversteer.
Certain
functions
of
some
systems
installed
in the

To
do
so,
brake
