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.'xDepending
on
the
equipment,
with
red
traffic
lights.'xFor
cross
traffic.'xFor
oncoming
traffic.Merging
vehicles
If
a
vehicle
driving
ahead
of
you
suddenly
merges
into
your
lane,
the
system
may
not
be
able
to
au#j tomatically
restore
the
selected
distance.
It
maynot
be
possible
to
restore
the
selected
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
reli#j
ably
detected,
the
system
requests
that
the
driver
intervene
by
braking
and
carrying
out
eva#j
sive
maneuvers,
if
needed.
Cornering
When
the
desired
speed
is
too
high
for
a
curve,the
speed
is
reduced
slightly.
Because
curves
may
not
be
anticipated
in
advance,
drive
into
a
curve
at
an
appropriate
speed.
The
system
has
a
limited
detection
range.
Situa#j tions
can
arise
in
tight
curves
where
a
vehicle
driving
ahead
will
not
be
detected
or
will
be
de#j
tected
very
late.

When
you
approach
a
curve
the
system
may
briefly
report
vehicles
in
the
next
lane
due
to
the bend
of
the
curve.
If
the
system
decelerates
youmay
compensate
it
by
briefly
accelerating.
After
releasing
the
accelerator
pedal
the
system
is
re#j
activated
and
controls
speed
independently.
Driving
off In
some
situations,
the
vehicle
cannot
drive
off
automatically;
for
example:
'xOn
steep
uphill
grades.'xIn
front
of
bumps
in
the
road.
In
these
cases,
step
on
the
accelerator
pedal.
Weather
The
following
restrictions
can
occur
under
unfav#j orable
weather
or
light
conditions:
'xPoorer
vehicle
recognition.'xShort-term
interruptions
for
vehicles
that
are
already
recognized.
Drive
attentively,
and
react
to
the
current
traffic situation.
If
necessary,
intervene
actively,
for
in#j
stance
by
braking,
steering
or
evading.
Drive
power
The
desired
speed
is
also
maintained
downhill.
The
speed
may
not
be
maintained
on
uphill grades
if
the
drive
power
is
insufficient.
In
ECO
PRO
drive
mode,
the
vehicle
may
exceed or
drop
below
the
set
desired
speed
in
some
sit#juations,
for
instance
on
downhill
or
uphill
grades.

Concept
When
the

To
apply
the
