CRUISE CONTROL SYSTEMS
Cruise Control — If Equipped
When engaged, the Cruise Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h). Cruise Control On/Off Switch
The Cruise Control buttons are located on the
left side of the steering wheel.
While driving downhill, the system could brake
the vehicle to keep the set speed the same.

NOTE:

In order to ensure proper operation, the Cruise
Control system has been designed to shut
down if multiple Cruise Control functions are
operated at the same time. If this occurs, the
Cruise Control system can be reactivated by
pushing the Cruise Control on/off button and
resetting the desired vehicle set speed.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Cruise Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

To Activate
To activate the Cruise Control system, push
the on/off button location on the left side of
the steering wheel.
The activation of the system is signaled by the
illumination of the white warning light on the
instrument cluster.Cruise Control Indicator Light
The Cruise Control function can remain active
at the same time as the Speed Limiter System.
If the set speed is higher than the speed set
with the Speed Limiter, the set speed will be
lowered to that of the Speed Limiter.
For Quadrifoglio vehicles, this function
remains available in RACE mode.

NOTE:

The system cannot be engaged in FIRST or
REVERSE gear. It is advisable to engage it in
THIRD gear or higher if using the AutoStick
feature.
To Set A Desired Speed
To set a desired speed, proceed as follows:
1. Turn the Cruise Control on.
2. When the vehicle has reached the desired speed, push the SET switch up or down
and release to activate. When the acceler -
ator is released, the vehicle will maintain
the selected speed automatically.
SET Switch Location If needed (when overtaking for instance), you
can accelerate beyond the set speed by
pressing the accelerator. When you release
the pedal, the vehicle will return to the previ
-
ously set speed.
When traveling downhill with the system
active, the vehicle speed may slightly exceed
the set one.

NOTE:

Before pushing the SET switch, the vehicle
must be traveling at a constant speed on a flat
surface.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can
increase the speed by pushing the SET switch
upward or decrease the speed by pushing the
SET switch downward.
U.S. Speed (mph)
Pushing the SET switch once will result in a
1 mph speed adjustment. Each subsequent
movement of the switch results in an adjust -
ment of 1 mph.
If the switch is continually pushed, the set
speed will continue to adjust until the switch
is released, then the new set speed will be
established.
WARNING!
Leaving the Cruise Control system on when
not in use is dangerous. You could
accidentally set the system or cause it to go
faster than you want. You could lose control
and have an accident. Always ensure the
system is OFF when you are not using it.
21_GA_OM_EN_USC_t.book Page 106

107

Metric Speed (km/h)
Pushing the SET switch once will result in a
1 km/h speed adjustment. Each subse -
quent movement of the switch results in an
adjustment of 1 km/h.
If the switch is continually pushed, the set
speed will continue to adjust until the switch
is released, then the new set speed will be
established.

NOTE:

Moving the SET switch allows for adjusting of
the speed according to the selected unit of
measurement set on the radio system. Refer
to the Information and Entertainment System
Owner’s Manual for more information.
To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Cruise Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.

NOTE:

The Cruise Control system maintains speed up
and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain
may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the
RES button and release. Resume can be used
at any speed above 20 mph (32 km/h).

NOTE:

Before resuming the previously set speed, you
must accelerate to a speed close to that
speed.
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
Adaptive Cruise Control (ACC) — If Equipped
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 105.
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.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Cruise Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.
21_GA_OM_EN_USC_t.book Page 107

STARTING AND OPERATING

108

(Continued)
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
guaranteed under the following circum
-
stances, 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
Ú
page 273.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience 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 oper -
ation 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 warn -
ings 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.
21_GA_OM_EN_USC_t.book Page 108

109

Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is
19 mph (30 km/h) and the maximum is110 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 deactiva -
tion 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 recom -
mended to deactivate it.
To Activate/Deactivate
The system has four operating states:
Enabled (speed not set)
Activated (speed set)
Paused
Deactivated
•
Does not always fully recognize
complex driving conditions, which can
result in wrong or missing distance
warnings.
• Will bring the vehicle to a complete
stop while following a vehicle ahead
and hold the vehicle for approximately
two minutes in the stop position. If the
vehicle ahead does not start moving
within two minutes, the parking brake
will be activated and the ACC sys t

em
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.

To Set A Desired Speed
When the vehicle reaches the desired speed,
push the RES/SET switch downward and
release it to activate the system. When the
accelerator is released, the vehicle will main
-
tain the set speed automatically. SET Switch
While the accelerator pedal is pressed, the
system will not be able to control the distance
between the vehicle and the one ahead. In this
case, the speed will be determined only by the
position of the accelerator pedal.
The system will return to normal operation as
soon as the accelerator pedal is released.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
Once the system has been activated, you can
increase the speed by pushing the RES/SET
switch upward or decrease the speed by
pushing the RES/SET switch downward. Each
time the switch is pushed, the speed is
adjusted by 1 mph.
Pushing and holding the switch upward or
downward will cause the set speed to adjust in
5 mph increments until the button is released.
The new set speed is reflected in the instru -
ment cluster display.
WARNING!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous.
You could accidentally set the system or
cause it to go faster than you want. You
could lose control and have a collision.
Always leave the system off when you are
not using it.
21_GA_OM_EN_USC_t.book Page 110

111

NOTE:

Moving the RES/SET switch downward
allows you to adjust the speed according to
the selected unit of measurement ("U.S." or
"Metric") set on the radio system. Refer to
the Information and Entertainment System
Owner’s Manual Supplement for further
information.
When the unit of measurement is set to
Metric, pushing and holding the RES/SET
switch will adjust the speed in 10 km/h
increments.
By keeping the accelerator pedal pressed,
the vehicle can continue to accelerate
beyond the set speed. In this case, use the
RES/SET switch to set the speed to the
vehicle’s current speed.
When you push the RES/SET button to
reduce the speed, the braking system inter-
venes 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, particu -
larly on slight inclines.
The transmission could shift to a lower gear
when driving downhill, or when acceler -
ating. This is normal and necessary to main -
tain 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
proportional 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.
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.
21_GA_OM_EN_USC_t.book Page 111

STARTING AND OPERATING

112

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 illumi -
nates from grey to white. The system automat -
ically 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 deac -
tivated/paused.
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 addi -
tional 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 auto
-
matically when the vehicle passes from left hand
traffic to right hand traffic. In this case, the over -
taking 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.
WARNING!
The maximum breaking applied by the
system is limited. The driver may apply the
brakes in all cases if needed.

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!

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.

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 bumper where the sensor is located.
Then check that the message has disap -
peared. When the conditions limiting the system func
-
tions 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 situa -
tions:
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or
a vehicle merging in from a side lane. There
may not be sufficient distance to the vehicle
ahead. The offset vehicle may move in and out
of the line of travel, which can cause your
vehicle to brake or accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged,
the system may increase or decrease the
vehicle speed for stability, with no vehicle
ahead detected. Once the vehicle is out of the
curve the system will resume your original set
speed. This is a part of normal ACC system
functionality.
NOTE:

On tight turns ACC performance may be
limited. In this case, it is advisable to deac
-
tivate the system.
The system only limits the speed DURING a
bend and not BEFORE it.
Turn Or Bend Example
Using ACC On Hills
When driving on hills, ACC may not detect a
vehicle in your lane. Depending on speed,
vehicle load, traffic conditions, and the steep -
ness of the hills, ACC performance may be
limited.

NOTE:

The driver must maintain control of the
vehicle, remain alert, and be ready to apply the
brakes if needed.
21_GA_OM_EN_USC_t.book Page 113

117

The right and left lane boundaries must be
visible
The vehicle speed must be between 0 and
90 mph (0 and 145 km/h)
The camera, radar, and radio system must
be functioning properly
The road lane width must be between 8.5 ft
and 13.7 ft (2.6 m and 4.2 m)
The turn signals must not be activated
The HAS system must be functioning prop-
erly
Other operating limits:
If the speed of ACC can be set to a higher
value (top speed 110 mph (180 km/h), HAS
is only available as long as the vehicle
speed is equal to or less than 90 mph
(145 km/h).
When the ACC speed is reduced and the
vehicle speed is less than 90 mph
(145 km/h), the system will automatically
reactivate.

If the ACC speed is set to 90 mph (145 km/h),
traveling downhill may increase the vehicle
speed. The HAS system will deactivate until
the speed returns to 90 mph (145 km/h).

Indications On The Display
The HAS system status can always be viewed
in the instrument cluster display.
The system status is indicated by the color of
the symbol on the display.
The HAS system uses sensors in the steering
wheel to detect if the driver’s hands are on it.
If the driver’s hands are not on the steering
wheel, a series of warnings will appear in the
instrument cluster display to alert the driver to
reposition their hands on the steering wheel.
An acoustic signal will also sound. After a
period of time, the HAS system will disable if
the driver’s hands do not return to the steering
wheel.
After a period of time, the HAS system will
disable if the driver has not repositioned their
hands on the steering wheel.
When the system does not detect hands on
the steering wheel, it will warn the driver by
displaying a dedicated screen on the instru -
ment cluster display.
System Status
Active System
When the system is active, the screen below
will appear in the “Driver Assistance” menu on
the instrument cluster display.
HAS Active
If on a different menu screen, a symbol will
appear on the instrument cluster display indi -
cating that the system is active.
When the driver’s hands are removed from the
steering wheel, the system disables after a few
seconds. A screen will appear in the instru-
ment cluster display warning the driver to
return their hands to the steering wheel.
