The general information applies to adaptive
cruise control* and pre sense front*
¢
page
139.
The radar sensor area
¢
fig.
116 must not be cov-
ered with stickers, deposits or any other obstruc-
tions as it may impair the function of the adap-
tive cruise control and the pre sense front. For in-
formation on cleaning, refer to
c:>
page
2 74. The
same applies for any modifications made in the
front area
.
The function of the adaptive cruise control sys-
tem and pre sense front
is
limited in some condi-
tions
:
-
Objects can only be detected when they are
within the sensor range

fig.
115.
-
The system has a limited ability to detect ob-
jects that are a short distance ahead, off to the
side of your vehicle or moving into your
lane.
-
Objects that are difficult to detect such as mo
-
torcycles, vehicles with
high
ground clearance
or an overhanging load are detected late or not
detected at all.
-
When driving through curves

A
WARNING
Always pay attention to traffic when adaptive
cruise control is switched on and the pre
sense front is active

.
As the driv-
er, you are still responsible for starting and
for maintaining speed and distance to other
objects. The pre sense front
is
used to assist
you. The driver must always take action to
Assist
avoid a collision. The driver is always responsi-
ble for braking at the correct time.
-
Using adaptive cruise control incorrectly can
cause collisions, other accidents and serious
injuries.
-
For safety reasons, do not use adaptive
cruise control when driving on
roads
with
many curves, when the road surface is in
poor condition and/or
in
bad weather (such
as ice, fog, gravel, heavy rain and hydroplan-
ing)
.
Using the system under these condi-
tions
could result
in
a collision.
-
Switch adaptive cruise control off tempora-
rily when driving in turning lanes, on ex-
pressway exits or in
construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations.
- The
adaptive
cruise control
system will not
brake
by itself
if you put your
foot on
the
ac-
celerator pedal.
Doing
so can override the
speed and
distance
regulation.
-
When approaching stationary objects such
as stopped traffic, adaptive cruise
control
will not respond and pre sense front will
have limited function.
-
The adaptive cruise control system and pre
sense front do not react to people, animals,
objects crossing the road or oncoming ob-
jects.
-
The function of the radar sensors can be af-
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
-
Always maintain enough distance from
vehicles ahead so that you can still brake
your vehicle safely
.
The
adaptive cruise con-
trol cannot safely slow your vehicle or brake
it to a stop if you
are
driving
too
close be-
hind
a
vehicle. Please note
that
the
auto-
matic braking
function
cannot
brake
sud-
denly or apply
the
brakes fully
under these
conditions.
- To
reduce the risk of
unintended actions,
switch the ACC off when you a
re
not actively
using it.
