Displayed Information CC conditions are displayed on the
instrument cluster after selecting
“Driver Assist” menu (see paragraph
“TFT Display: Menus and Settings"
under “Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
Displayed information depends on
system status: ready, disabled,
cancelled or set.
Apart from the pop-up messages at
the centre of the display, CC system
status is represented by icons at the
top left. These icons remain displayed
even when you exit the "Driver Assist"
screen.
The CC screen can be displayed any
time the driver changes system status
or settings. After 5 seconds of CC
inactivity, the display goes back to last
screen.

Using Electronic Cruise Control
on Hills The transmission may be downshifted
on hills to maintain the vehicle set
speed. The CC system maintains set
speed up and down hills. A slight
speed change on moderate hills is
normal. On steep slopes it is
recommended to drive without CC.
WARNING!
Electronic Cruise Control can be
dangerous where the system cannot
maintain a constant speed. Do not use
electronic Cruise Control in heavy
traffic or on winding, icy,
snow-covered or slippery roads. Adaptive Cruise Control -
ACC (optional) ADAS Equipments The Adaptive Cruise Control (ACC) is
part of ADAS equipments together
with:
• Lane Keeping Assist (LKA)
• Active Blind Spot Assist (ABSA)
• Forward Collision Warning (FCW)
• Highway Assist (HAS)
• Traffic Sign Assist (TSA).
FCW, HAS and TSA are separate
functions that may not be present in
the ADAS equipment. For more details
see “Forward Collision Warning -
FCW”, “Highway Assist - HAS" and
"Traffic Sign Assist - TSA" in this
section.
NOTE:
LKA and ABSA are described in the
relevant chapters of this section.
ACC Preview The Adaptive Cruise Control (ACC)
further increases the drive comfort
ensured by the Cruise Control when
driving on highways and freeways.
Always consider that ACC is not a safety system and is not designed to
prevent accidents.
The ACC allows driver to keep Cruise
Control active in limited or moderate
traffic conditions with no need to
constantly restore the Cruise Control.
The ACC uses a radar sensor, located
on the front grille behind the trident,
and the forward-facing camera behind
the internal rear-view mirror to detect
the presence of a vehicle ahead at a
close distance and moving in the same
direction.
This vehicle, in this chapter, will be
indicated as "target vehicle" or
"vehicle ahead".
NOTE:
• If the sensor detects no vehicle
ahead, the ACC system will maintain
set steady speed.
• If the ACC sensor detects a vehicleDriving
5
286
ahead, the ACC system automatically
kicks in by slightly accelerating or
braking (to avoid exceeding the
initially set speed) so that the vehicle
keeps present distance, trying to
adapt to the speed of the detected
vehicle ahead.
WARNING!
• The Adaptive Cruise Control (ACC) is
designed to increase vehicle driving
comfort. It must not be considered
as a means of replacing the required
attention of the driver. The driver is
always required to drive carefully.
The driver is always required to pay
utmost attention to driving
conditions (road, traffic, weather)
and style (speed, distance from
sensed vehicle ahead, brake use).
Driver has the full responsibility of
the vehicle therefore his attention is
crucial to keeping vehicle control, in
particular when approaching curves
and situations with heavy traffic.
Failure to follow these warnings can
result in a collision and death or
serious personal injury
• In some driving scenarios, the ACC
could have detection problems. In
such cases, the ACC could kick in late or unexpectedly. The driver must be
careful since his/her intervention
could be necessary.
• It is always the driver’s responsibility
to obey speed limits and to keep
minimum legal distance to the
preceding vehicle.
• ACC system can decelerate only with
limited braking, it cannot execute
emergency braking.
The ACC system:
•
Does not activate/react in the
presence of pedestrians, bicycles,
incoming traffic from opposite
direction and steady objects such as
a vehicle stuck in a traffic jam.
• Is meant for the use on highways
and well-built roads, not for city
traffic or mountain roads.
• May not have enough time to react
and/or decelerate sufficiently on
vehicles when lane is changed too
quickly or the relative speed is too
high. In such cases the driver has to
react appropriately and without any
acoustic/visual warning.
• Cannot consider road, traffic and
weather conditions and might prove
limited when visibility is poor.
• Does not always fully recognize
complex driving conditions and this could cause an incorrect assessment
of the required safety distance.
It is recommended to disable the ACC
system in the following instances:
• When driving in the fog, heavy rain,
heavy snow, slush, heavy traffic and
similar complex situations such as
highway construction zones.
• When entering a junction lane or a
slip road to leave the highway; when
driving on narrow, icy, snowy,
slippery roads, or on uphill and
downhill roads.
• The system is designed and calibrate
for car with no trailer.
• When circumstances do not allow to
drive safely at constant speed.
Displayed information Adaptive Cruise Control (ACC)
condition, as well as the LKA and HAS
status, is displayed on instrument
cluster after selecting “Driver Assist”
menu (see paragraph “TFT Display:
Menus and Settings” under
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
Displayed information depends on
system status: ready, set, temporarily
cancelled or override.Driving

disabled.
WARNING!
Leaving the Adaptive Cruise Control
(ACC) system on when not in use is
dangerous. You could accidentally
activate the system or cause it to go
faster than you want. Always leave
the system off when you are not using
it.
Setting the Speed When the vehicle reaches the required
speed, press down and release the
multifunction control (SET -). The
display will show set speed
corresponding to vehicle current one.
Speed value will be indicated below
the
green symbol and above the distance bars, in the center of the
display.
Remove foot from accelerator pedal
and vehicle will continue at set speed.
Driver Override If driver accelerates beyond the set
speed or faster than the car would do
with ACC engaged, the set speed
below the
green light will blink and
the time gap bars will vanish to
indicate that in this condition the
system cannot control the distance
between vehicle and sensed vehicle
ahead. Vehicle speed will be
determined only by the accelerator
pedal position.
Changing Speed Setting Once speed is set, driver can increase
or decrease it by respectively pressing
multifunction control up (RES +) or down (SET -). Speed can be increased
or decreased in two ways:
• Pressing control once, set speed will
increase or decrease by one unit
corresponding to 1 mph (1 km/h).
• Hold the control to increase or
decrease set speed by 5 mph
(10 km/h) at a time.
NOTE:
• When pressing the multifunction
control up (RES +) or down (SET -),
the new set speed will be the current
speed of the vehicle.
• When using (SET -) control to
decelerate, if the engine braking
power does not slow down the
vehicle sufficiently to reach the set
speed, the brake system will
automatically slow down the vehicle.
• The ACC system applies the brake
down to a full stop when following a
target vehicle. If an ACC host vehicle
follows a target vehicle to a
standstill, after a two or three second
delay, the system will not be able to
resume driving the car
autonomously. At this point it is
necessary for the driver to manually
reengage the system by either using
the multifunction control (press SET-
or RES+) or by pressing theDriving
5
290
accelerator pedal (see “ACC
Operation Before and During Stop”
in this chapter).
• The ACC system maintains set speed
when driving up hill and down hill.
However, a slight speed change on
moderate hills is normal. In addition,
downshifting may occur while
climbing uphill or descending
downhill. This is normal operation
and necessary to maintain set speed.
When driving uphill and downhill,
the ACC system will cancel if the
braking temperature exceeds normal
range.
Temporary Deactivation A soft tap on the brake pedal, pushing
the multifunction control (CANC), or
normal brake pressure while slowing
the vehicle will temporarily deactivate
the ACC without erasing the set speed
memory. The
white light will appear
on the display with below the set
speed.
Conditions for Disabling and
Deactivation Besides the cases specified in the
previous paragraph, the following
conditions will disable the system:
• Anti-Lock Brake (ABS) kicks in. • Transmission lever is not in D (Drive).
• “CORSA” drive mode (TROFEO
version only) is set.
• Ride height is set to “Off Road 1” or
“Off Road 2”.
• The Electronic Stability Control and
the Traction Control System
(ESC/TCS) activate.
• Vehicle parking brake is operated.
• The driver safety belt is unbuckled at
low speed.
• The driver door is ajar at low speed.
• The driver disabled the ESC using the
(ESC OFF) button on central
console.
• The road is too steep both uphill and
downhill at low speed.
The system is deactivated and set
speed is deleted from system memory,
if the ACC ON/OFF button is pressed or
if ignition device is turned to OFF .
Resuming Speed If a speed setting is stored in system
memory, press the multifunction
control (RES +) up and take foot off
the accelerator pedal. The last set
speed will be displayed. WARNING!
The resume function should be used
only when road and traffic conditions
allow it. Resuming a too high or too
low speed for current traffic and road
conditions could cause a harsh vehicle
acceleration or deceleration which
could increase the risk of collisions
and death or serious injury.
Setting the ACC Gap The specified ACC gap can be set by
varying the distance setting among
the four possible options identified by
the number of horizontal bars:
• Maximum (longest) distance: 4 bars.
• Long distance: 3 bars (default
distance).
• Medium distance: 2 bars.
• Short distance: 1 bar.
Using this distance setting and the
vehicle speed, ACC calculates and sets
the gap to the vehicle ahead.
If system does not detect the presence
of any vehicles ahead, only the bars
referred to set distance will be
displayed.
When system detects the presence of a
vehicle ahead, it is displayed in front
of the bars (see example in the figure).Driving
5
291
To increase or decrease the number of
bars, corresponding to the gap from
vehicle ahead, press and release the
distance setting button. Each press and release of the button
changes the gap starting from 3 bars
(default distance) and moving in a
sequential way towards the minimum
distance: 3 → 2 → 1 → 4 → 3 → 2 → 1 → 4 and so
on.
If there is no vehicle ahead, the vehicle
will maintain the set speed. If a slower
moving vehicle is detected in the same
lane, the system displays the target
vehicle icon before the bars. From that
moment, the system adjusts the vehicle
speed automatically to maintain the
distance setting, regardless of the set
speed.
The vehicle will then maintain the set
distance until:
• The vehicle ahead accelerates to a
speed above the set speed.
• The vehicle ahead moves out of the
lane or view of the sensor.
• The distance setting is changed. • The driver disables the system.
The maximum braking applied by ACC
is limited; however, the driver can
always apply the brakes manually, if
necessary. Any time the ACC system
automatically operates the brakes, the
brake lights will turn on as if the driver
was braking.
A Proximity Warning on display will
alert the driver if ACC predicts that its
maximum braking level is not
sufficient to maintain the set distance.
If this occurs, a visual alert will flash on
the display and a chime will sound
while ACC continues to apply its
maximum braking capacity.Driver Assist Page

(Continued)
The driver has the responsibility to
avoid a collision by controlling the
vehicle via braking and steering.
Failure to follow this warning could
lead to serious injury or death.
FCW Operation The FCW provides audible and visual
warnings when a potential collision is
detected. Brake jerk and limited
braking may also be applied
depending on the specific scenario.
NOTE:
FCW system is not intended for
towing: this could lead the system to
malfunctions and/or to late reaction.
FCW monitors the information from
the forward looking radar sensor as
well as the Electronic Brake Controller
(EBC), to calculate the probability of a
forward collision. When the system
determines that a forward collision is
probable, the driver will be provided
with audible and visual warnings and
may provide a warning brake jerk. If
the driver does not take action based
upon these progressive warnings, then
the system will provide a limited level
of active braking to help slow down
the vehicle and mitigate the potential forward collision. If the driver reacts to
the warnings by braking and the
system determines that the driver
intends to avoid the collision by
braking but has not applied sufficient
brake force, the system will
compensate and provide additional
brake force as required.
When the system determines a
collision with the vehicle in front of
you is no longer probable, the warning
messages will be deactivated.
NOTE:
• Bad weather conditions, like strong
rain, snow, etc., can lead to reduced
system performance. Under these
conditions relevant objects will not
be detected or detected late by the
system.
• FCW is designed to react in specific
situations in typical traffic scenarios
with objects in the same lane driving
in the same direction, but under
certain conditions it can also react on
stationary objects in the same lane. It
is not designed to react to oncoming
traffic or crossing traffic.
• The FCW alerts may be triggered on
objects other than vehicles such as
guard rails or sign posts based on the
course prediction. This is expected
and is a part of normal FCW activation and functionality.
• It is unsafe to test the FCW system.
To prevent such misuse of the system,
after four Active Braking events
within a key cycle, the Active Braking
portion of FCW will be deactivated
until the next key cycle. The limit of
four events applies to the brake jerk
too.
• The FCW system is intended for
on-road use only. If the vehicle is
taken off-road, the FCW system
should be deactivated to prevent
unnecessary warnings. If the vehicle
ride height is set to “Off Road 1” or
“Off Road 2”, the FCW system will be
automatically deactivated.
• FCW will automatically deactivated
when
(ESC OFF) button is pressed
(LED light up) and when HDC is
active.
WARNING!
• Forward Collision Warning (FCW) is
not intended to avoid a collision on
its own, nor can FCW detect every
type of potential collision. The driver
has the responsibility to avoid a
collision by controlling the vehicle
via braking and steering. Failure toDriving
5
298
follow this warning could lead to
serious injury or death. The driver is
always in charge to safely drive and
to avoid critical situations not
relying on the support of the
system. Driver has to keep in mind
that the system and therefore its
intervention is always subject to the
prevailing physical limits.
• Forward Collision Warning (FCW) is
not intended either to warn or to
apply any brake aid/brake
intervention in case of collisions
with pedestrians (if not equipped
with PEB sub-system), bicycles and
not licensable vehicles in general.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated 1.12 (1.8)
Maximum 155 (250)
When the speed is outside the
specified limits, the system
automatically disables without turning
on the corresponding warning light
on the instrument cluster. FCW Status The driver can adjust FCW sensitivity
or enable/disable the brake actuation
with the other emergency brakings by
touching "Controls" soft-key on MTC+
display. The current setting is indicated
beside to the "Forward Collision
Warning" soft-key. If you want to
change the setting, touch the soft-key
on the side to enter FCW page.
Setting options are described in the
following paragraph.
When FCW status for some reason
changes to off, the corresponding
amber warning light on instrument
cluster will light on. This warning light informs the driver
that FCW is disabled. This warning
light will light even when the
activation of another driver assistance
feature or drive mode (example:
(ESC OFF)) disables the FCW.
NOTE:
The FCW system setting is kept in
memory from one key cycle to the
next.
Changing FCW Sensitivity and
Active Braking The default status of FCW Sensitivity is
the “Medium” setting. When the
active braking function (“Forward
Collision Warning Active Braking”)
setting is on, the system warns you of
a possible collision with the vehicle in
front of you when you are farther
away and it applies limited braking.Driving
