System
limits
Detection
range
The
detection
capacity
of
the
system
and
the
automatic
braking
capacity
are
limited.
Two-wheeled
vehicles
for
instance
might
not
be
detected.
Deceleration The
system
does
not
decelerate
in
the
followingsituations:
'xFor
pedestrians
or
similarly
slow-moving
road users.'xFor
red
traffic
lights.'xFor
cross
traffic.'xFor
oncoming
traffic.Swerving
vehicles
A
vehicle
driving
in
front
of
you
is
not
detected
until
it
is
completely
within
the
same
lane
as
your vehicle.
If
a
vehicle
driving
ahead
of
you
suddenly swerves
into
your
lane,
the
system
may
not
be
able
to
automatically
restore
the
selected
disj
tance.
It
may
not
be
possible
to
restore
the
sej lected
distance
in
certain
situations,
including
if
you
are
driving
significantly
faster
than
vehicles driving
ahead
of
you,
for
instance
when
rapidly
approaching
a
truck.
When
a
vehicle
driving
ahead
of
you
is
reliably
detected,
the
system
rej
quests
that
the
driver
intervene
by
braking
and
carrying
out
evasive
maneuvers,
if
needed.
Cornering
If
the
desired
speed
is
too
high
for
a
curve,
the
speed
is
reduced
slightly,
although
curves
canj
not
be
anticipated
in
advance.
Therefore,
drive
into
a
curve
at
an
appropriate
speed.
The
system
has
a
limited
detection
range.
Situaj tions
can
arise
in
tight
curves
where
a
vehicledriving
ahead
will
not
be
detected
or
will
be
dej
tected
very
late.
