DESCRIPTION
The Adaptive Cruise Control (ACC) is a
driver assist device which combines the
Cruise Control functions with one for
controlling the distance from the vehicle
ahead.
The device allows to hold the car at the
desired speed without needing to press
the accelerator. It also allows to hold a
given distance from the vehicle ahead
(the distance can be set by the driver).
The Adaptive Cruise Control (ACC) uses
a radar sensor, located behind the front
bumper fig. 120, to detect the presence
of a vehicle close ahead.The device further enhances driving
comfort provided by the electronic
Cruise Control when on the motorway
or out of town with light traffic.
Using the device is not beneficial on
busy extra-urban roads or on urban
streets.
IMPORTANT NOTES
If the sensor does not detect any
vehicle ahead, the device will maintain a
fixed set speed.
If the sensor detects a vehicle ahead,
the device automatically brakes to avoid
getting closer than the set distance.
Once behind a vehicle, the system will
brake or accelerate to maintain the
distance, without ever exceeding the
set speed.
It is advisable to turn the device off in
the following cases:
driving in fog, heavy rain, snow,
heavy traffic and in complex driving
situations (e.g. on motorways with
roadworks in progress);
driving near a bend (winding roads),
icy, snowy, slippery roads or with steep
slopes and descents;
entering a turn lane or on a slip road;
towing a trailer;
when circumstances do not allow
safe driving at a constant speed.There are two operating modes:
“Adaptive Cruise Control” mode
to hold an appropriate distance
between vehicles (a dedicated message
is shown on the instrument panel
display);
electronic “Cruise Control” mode
to hold the vehicle at a constant
preset speed.
To change the operating mode, use the
button on the steering wheel (see that
described on the following pages).
The "electronic Cruise Control" does
not alter the speed if there are vehicles
in front. Always adjust the speed
according to traffic conditions.

To activate the device, press and
release the button
fig. 121.

STARTING AND DRIVING
In left-hand traffic, the overtaking assist
function is only active when the
left-hand lane is used for overtaking the
vehicle ahead (the opposite activation
logic is used in right-hand traffic
countries).
The device detects the direction of
traffic automatically when the car
passes from left-hand traffic to
right-hand traffic. In this case, the
overtaking assist function is only active
when the reference vehicle is overtaken
on the right.
The additional acceleration is activated
when the driver uses the right direction
indicator.
In this condition, the device no longer
provides the overtaking assist function
on the left-hand side until it determines
that the car has returned to left-hand
traffic conditions.
IMPORTANT For versions equipped
with dual-clutch automatic
transmission, the ECO function also
acts on the acceleration
responsiveness of the Adaptive Cruise
Control. If you prefer a more responsive
behaviour, you can turn off the ECO
function or operate the accelerator
pedal. In the latter case, normal
Adaptive Cruise Control operation will
resume when the pedal is released.RECALLING THE SPEED
Once the system has been cancelled
but not deactivated, if a speed was
previously set simply press the RES
(Resume) button and remove your foot
from the accelerator to recall it.
The system will be set to the last stored
speed.
Before returning to the previously set
speed, bring the speed close to that
value, press the RES (Resume) button
and then release it.
IMPORTANT The recall function must
only be used if the road and traffic
conditions so allow. Recalling an
excessively high or low speed for the
current traffic and road conditions could
cause an acceleration or a deceleration
of the vehicle. Failure to comply with
these precautions may cause serious
accidents and fatal injuries.
SETTING THE DISTANCE
BETWEEN VEHICLES
The distance between your vehicle and
the vehicle ahead may be set to 1 bar
(short), 2 bars (medium), 3 bars (long),
4 bars (maximum) (see fig. 123 ).The distances from the vehicle ahead
are proportional to speed. The interval
of time with respect to the vehicle
ahead remains constant and varies
from 1 second (for the short distance
1-bar setting) to 2 seconds (for the
maximum distance 4-bar setting).
The set distance is shown on the
display with a symbol in the “Driver
Assist” area.
123P2000094-000-000
127
The setting is 4 (maximum) the first time
the device is used. After the distance
has been modified by the driver, the
new distance will be stored also after
the system is deactivated and
reactivated.
To decrease the distance
Press and release the
button to
decrease the distance setting.
The distance setting decreases by one
bar (shorter) every time the button is
pressed.
The set speed is held if there are no
vehicles ahead. Once the shortest
distance has been reached, a further
press of the button will set the longest
distance.
If a slower vehicle is detected in the
same lane, it will be shown on the
display in the “Driver Assist” area. The
device will automatically adjust the car’s
speed to maintain the set distance,
independently of the set speed.
The vehicle holds the set distance until:
the vehicle ahead accelerates to a
speed higher than the set speed;
the vehicle ahead leaves the lane or
the detection field of the Adaptive
Cruise Control device sensor;
the distance setting is changed;
the Adaptive Cruise Control device is
deactivated/cancelled.
IMPORTANT The maximum breaking
applied by the device is limited. The
driver may apply the brakes in all cases
if needed.
IMPORTANT If the device predicts that
the braking level is not sufficient to hold
the set distance, the driver is warned by
a message indicating that the vehicle
ahead is too close. An acoustic signal is
also emitted. In this case, it is advisable
to brake immediately as necessary to
hold a safe distance from the vehicle
ahead.
IMPORTANT The driver is responsible
for ensuring that there are no
pedestrians, other vehicles or
objectives along the direction of the
vehicle. Failure to comply with these
precautions may cause serious
accidents and injuries.
IMPORTANT The driver is fully
responsible for holding a safe distance
from the vehicle ahead respecting the
highway code in force in the respective
country.
DEACTIVATION
The device is deactivated and the set
speed is cancelled if:
thebutton is pressed on the
Adaptive Cruise Control;
thebutton is pressed on the
electronic Cruise Control;
the Speed Limiter button is pressed;
the ignition device is in the STOP
position.
The device is cancelled (the set speed
and distance are stored):
when the CANC button is pressed;
when the conditions shown in the
“Setting the desired speed” paragraph
occur;
when the vehicle speed drops under
the minimum set speed (e.g. in
presence of slow vehicles).
If these conditions occur while the
system is decelerating with respect to a
vehicle ahead, the system could
continue the deceleration, if necessary,
also after it is cancelled or deactivated
within the minimum speed settable on
the system.
SYSTEM LIMITED
OPERATION WARNING
If the dedicated message is shown on
the display, a condition limiting the
system operation may have occurred.
This limitation could be caused by a
fault or obstruction of the radar sensor.
If an obstruction is signalled, clean the
area of the bumper in which the sensor
is located in fig. 120 and check that the
message has disappeared.
