How to use Remote Start
All of the following conditions must be met
before the engine will remote start:
Gear selector in PARK (P).
Doors closed.
Hood closed.
Trunk closed.
Hazard switch off.
Brake switch inactive (brake pedal not
pressed).
Battery at an acceptable charge level.
PANIC button not pushed.
System not disabled from previous remote
start event.
Vehicle alarm system indicator flashing.
Ignition in the OFF mode.
Fuel level meets minimum requirement.
Remote Start Comfort Systems — If Equipped
When Remote Start is activated, the heated
steering wheel and driver heated seat features
will automatically turn on in cold weather.
These features will stay on through the dura -
tion of remote start also until the ignition is
placed in the ON/RUN mode. Remote Start Windshield Wiper De–Icer Acti
-
vation — If Equipped
When remote start is active and the outside
ambient temperature is less than 39°F (4°C),
the Windshield Wiper De-Icer will be enabled.
Exiting remote start will resume previous oper -
ation, except if the Windshield Wiper De-Icer is
active.
The Windshield Wiper De-Icer timer and oper -
ation will continue.
Cold Weather Operation
To prevent possible engine damage while
starting at low temperatures, this vehicle will
inhibit engine cranking when the ambient
temperature is less than –22°F (–30°C) and
the oil temperature sensor reading indicates
an engine block heater has not been used. An
externally-powered electric engine block
heater is available as optional equipment or
from an authorized dealer.
The message “plug in engine heater” will be
displayed in the instrument cluster when the
ambient temperature is below 5°F (–15°C) at
the time the engine is shut off as a reminder to
avoid possible crank delays at the next cold
start.
Extended Park Starting
If the vehicle has not been started or driven for
at least 30 days, it is advisable to follow the
indications below.
To start the engine, proceed as follows:
1. Briefly push the ignition button
2. If the engine does not start, wait five seconds and let the starter cool down and
then repeat the starting procedure
3. If the engine does not start after eight attempts, let the starter cool down for at
least 10 seconds, and then repeat the
starting procedure
If the problem persists, contact an authorized
dealer.

NOTE:

After prolonged vehicle inactivity, very difficult
starting, that can be noticed through rapid
fatigue of the starter, might also be due to a
discharged battery. In this case you may jump
start the vehicle
Ú
page 199.
CAUTION!
Use of the recommended oil and adhering
to the prescribed oil change intervals is
important to prevent engine damage and
ensure satisfactory starting in cold
conditions.

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

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.
WARNING! (Continued)

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.

21_GA_OM_EN_USC_t.book Page 112

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 109
When the conditions shown in the “Acti -
vating Adaptive Cruise Control (ACC)”
section occur
Ú
page 109
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.
