ENGINE RESTARTING CONDITIONS
Due to comfort, emission control, and safety
reasons, the engine can restart automatically
without any action by the driver, under special
conditions, such as:
Battery not sufficiently charged.
Reduced braking system vacuum (e.g. if the
brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on roads
with a grade).
Engine stopping by the Stop/Start system for
more than approximately three minutes.
With the automatic climate control active, an
adjustment in cabin heating or cooling is made
or with MAX-DEF function active.
SAFETY FUNCTIONS
When the engine is stopped through the Stop/
Start system, if the driver releases their seat belt,
opens the driver's or passenger's door, or opens
the hood from inside the vehicle, the engine can
be restarted only by using the ignition.
This condition is indicated to the driver both
through a buzzer and a message on the
instrument cluster display.
ENERGY SAVING FUNCTION
If the driver does not carry out any action for more
than three minutes after the automatic engine
restart, the Stop/Start system will switch off the
engine in order to prevent fuel consumption.
In this situation, the engine can only be restarted
using the ignition device.

NOTE:
It is possible to keep the engine running by deac-
tivating the system.
IRREGULAR OPERATION
In the event of malfunction, the Stop/Start
system is deactivated.
For failure indications

VEHICLE INACTIVITY
In the event of vehicle inactivity (or if the battery
is replaced), special attention must be paid to the
disconnection of the battery power supply.
Proceed as follows:
Remove connector from socket to disconnect
sensor (battery status monitoring) installed on
the negative pole of the battery. This sensor
should never be disconnected from the pole
except if the battery is replaced. Battery Power Supply

NOTE:
After setting the ignition to OFF and having closed
the driver side door, wait at least one minute
before disconnecting the electrical supply from
the battery. When reconnecting the electrical
supply to the battery, make sure that the ignition
is in the OFF position and the driver side door is
closed.

Resume Button Location
In AutoStick (sequential) mode, before resuming
the previously set speed, you should accelerate
until you are close to that speed. Then, push and
release the RES button.
To Deactivate
A tap on the brake pedal deactivates the Cruise
Control without deleting the set speed.
The Cruise Control may also be deactivated by
applying the Electric Park Brake or when the
braking system is operated (e.g. operation of the
Electronic Stability Control (ESC) system).
The set speed is deleted in the following cases:
Pushing the on/off button a second time
The ignition is placed in the OFF position
If there is a malfunction with the Cruise Control
system
ADAPTIVE CRUISE CONTROL (ACC)
The Adaptive Cruise Control (ACC) is a driver
assist system that combines the Cruise Control
functions with controlling the distance from the
vehicle ahead. ACC increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not
designed to prevent collisions. The Cruise Control
function performs differently

Ú
page 98.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
uses a radar sensor located behind the front
bumper and a camera located in the center/
upper part of the windshield, to detect the
presence of a vehicle close ahead.
The system sets and holds the vehicle at the
desired speed without needing to press the
accelerator. It also sets and holds a distance
from the vehicle ahead (these settings are set by
the driver).
Front Bumper Radar Location Windshield Camera Location
If the system detects a vehicle ahead, it will
automatically intervene by slightly braking or
accelerating in order to maintain the preset
distance. It will not exceed the original set speed
when adapting to the speed of the vehicle ahead.

NOTE:
Adaptive Cruise Control performance is not guar -
anteed under the following circumstances, and it
is recommended to turn the system off when:
Driving in fog, heavy rain, or snow.
Driving in heavy traffic or construction zones.
Driving on icy, snowy, slippery roads, roads
with steep inclines, or roads with numerous
turns and bends.
Entering a turn lane.
When circumstances do not allow safe driving
at a constant speed

(Continued)
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is
19 mph (30 km/h) and the maximum is 110 mph
(180 km/h).
The system cannot be activated:
When pressing the brake pedal.
When the brakes are overheated.
When the Electric Park Brake has been
operated.
When either PARK, REVERSE or NEUTRAL is
engaged.
When the engine RPM is above a maximum
threshold.
When the vehicle speed is not within the
operational speed range.
When the Electronic Stability Control (ESC) (or
Anti-Lock Brake System (ABS) or other stability
control systems) are operating or have just
operated.
When the ESC system is off.
When the Forward Collision Warning system (if
equipped) is braking automatically.
In the event of a system failure.
When the engine is off.
In case of obstruction of the radar sensor (in
this case the bumper area where it is located
must be cleaned).
If the system is set, the conditions described
above also cause a cancellation or deactivation
of the system. These situations may vary
according to the conditions.

NOTE:
The system will not be deactivated when speeds
higher than those set are reached by pressing the
accelerator pedal above 110 mph (180 km/h). In
these situations, the system may not work
correctly and it is recommended to deactivate it.
To Activate/Deactivate
The system has four operating states:
Enabled (speed not set)
Activated (speed set)
Paused
Deactivated
WARNING!
Adaptive Cruise Control (ACC) is a
convenience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of road,
traffic, and weather conditions, vehicle
speed, distance to the vehicle ahead and,
most importantly, brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is
always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision and
death or serious personal injury.
The ACC system:
• May react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a stopped vehicle in a traffic jam or a disabled vehicle) at speeds between 2 mph and 35 mph (4 km/h and
60 km/h).
• Cannot take street, traffic, and weather
conditions into account, and may be limited upon adverse sight distance conditions.
• Does not always fully recognize complex
driving conditions, which can res ult in
wrong or missing distance warnings.
• Will bring the vehicle to a complete stop
while following a vehicle ahead and holdthe vehicle for approximately twominutes in the stop position. If thevehicle ahead does not start movingwithin two minutes, the parking brakewill be activated and the ACC system will be canceled.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving
situations (i.e., in highway construction
zones).
When entering a turn lane or highway
off-ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or have
steep uphill or downhill slopes.
When circumstances do not allow safe
driving at a constant speed.
WARNING!
22_GU_OM_EN_USC_t.book Page 101

103
(Continued)
When you push the RES/SET button to reduce
the speed, the braking system intervenes
automatically if the engine brake does not slow
the vehicle down sufficiently to reach the set
speed. The device holds the set speed uphill
and downhill; however a slight variation is
entirely normal, particularly on slight inclines.
The transmission could shift to a lower gear
when driving downhill, or when accelerating.
This is normal and necessary to maintain the
set speed.
The system will disable while driving if the
brakes overheat.
To Resume
Once the system has been canceled but not
deactivated, to resume a previously set speed,
simply push the RES/SET switch upward and
remove your foot from the accelerator to recall it.
The system will be set to the last stored speed.
Setting The Distance Between Vehicles
The distance between your vehicle and the
vehicle ahead may be set to one bar (short), two
bars (medium), three bars (long), or four bars
(maximum).Distance Icons
The distances from the vehicle ahead are propor -
tional to speed.
The interval of time with relation to the vehicle
ahead remains constant and varies from one
second (for the short distance one-bar setting) to
two seconds (for the maximum distance four-bar
setting).
The set distance is shown on the display by a
dedicated icon.
The setting is four bars (maximum) the first time
the system is used. After the distance has been
modified by the driver, the new distance will be
stored even if the system is deactivated and
reactivated.
To Decrease The Distance
Push and release the distance button to decrease
the distance setting. The distance setting
decreases by one bar (shorter) every time the
button is pushed. Distance Button
The set speed is held if there are no vehicles
ahead. Once the shortest distance has been
selected, the next push of the button will set the
maximum distance.
If a slower vehicle is detected in the same lane,
the vehicle icon on the display illuminates from
grey to white. The system automatically adjusts
the vehicle’s speed to keep 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
system sensor.
The distance setting is changed.
The Adaptive Cruise Control system is
deactivated/paused.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to follow
these warnings can result in a collision and
death or serious personal injury.
WARNING!
The maximum braking applied by the system
is limited. The driver may apply the brakes in
all cases if needed.

Overtake Aid

When driving with ACC engaged and following a
vehicle at a speed greater than 45 mph (70 km/h),
the system will provide an additional acceleration
up to the ACC set speed to assist in passing the
vehicle. This additional acceleration is triggered
when the driver utilizes the left turn signal and will
only be active when passing on the left hand side.

The system detects the direction of traffic
automatically when the vehicle 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 deactivated when the
driver uses the right direction indicator and
returns to the original lane.
Stop And Go Function
The Stop and Go operating strategy allows you to
maintain a safe distance from the vehicle ahead
until the vehicle has completely stopped.
In the event that the ACC system brings your
vehicle to a standstill while following the vehicle
in front, if the vehicle in front starts moving within
two seconds of your vehicle coming to a
standstill, your vehicle will resume motion
without the need for any driver action.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a
standstill, the driver will have to push the RES/
SET switch upward to restart.
Deactivation
The system is deactivated and the set speed is
canceled if:
The on/off button is pushed (when the system
is on or paused)
The ignition is placed in the OFF position
RACE mode is activated (Quadrifoglio models)The system is canceled (the set speed and
distance are stored):
When the system is paused
Ú
page 101
When the conditions shown in the “Activating
Adaptive Cruise Control (ACC)” section occur

Ú
page 101
Limited Operation Warning
If the dedicated message is shown on the display,
a condition limiting the Adaptive Cruise Control
operation may have occurred.
This could be due to an obstruction of the
vehicle’s sensor or camera. It could also be due
to a fault in the system. If an obstruction is
detected, clean the area of the windshield
opposite the interior rearview mirror, where the
camera is located, as well as the area of the front
fascia/bumper where the sensor is located. Then
check that the message has disappeared.
When the conditions limiting the system
functions end, normal operation will resume.
Should the fault persist, contact an authorized
dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay
alert and may need to intervene. The following
are examples of these types of situations:
Towing A Trailer
Towing a trailer is not recommended when using
ACC.
If the system predicts that the braking level is
insufficient to hold the set distance, either
“BRAKE!” or a dedicated message is
displayed to warn the driver of approaching
the vehicle ahead. An acoustic signal is also
emitted. In this case, it is advised to brake
immediately as necessary to hold a safe
distance from the vehicle ahead.
The driver is responsible for ensuring that
there are no pedestrians, other vehicles or
objects along the direction of the vehicle.
Failure to comply with these precautions may
cause serious accidents and injuries.
The driver is fully responsible for holding a
safe distance from the vehicle ahead
respecting the highway code in force in the
respective country.
WARNING!
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.
