Concept
The

of
the
surrounding

of
the

Additionally,
the

There
are
various

Data
protection The
permissibility
of
recording
and
using
video
recordings
is
contingent
upon
the
statutory
regu#j
lations
of
the
country
in
which
the
system
is
to
be
used.
The
user
is
responsible
for
the
use
of
the
system
and
compliance
with
the
respective
regulations.
The
manufacturer
of
the
vehicle
recommends confirming
there
are
no
statutory
or
regulatory
constraints
on
use
of
the
system
in
your
state
or
country
prior
to
the
initial
use.
In
addition,
the
laws
with
respect
to
use
of
the
system
should
be
verified
in
regular
intervals,
especially
when
bor#j
ders
are
frequently
crossed.
Other
drivers
of
the

must
be
