STARTING AND OPERATING

94

REVERSE (R)
Select this mode only with the vehicle at a
standstill.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. The
engine may be started in this range. Apply the
EPB and shift the transmission into PARK (P) if
you must leave the vehicle.DRIVE (D)
Use this mode in normal driving conditions.
Shifting from DRIVE (D) to PARK (P) or REVERSE
(R) modes must take place only after releasing
the accelerator pedal, with vehicle at a standstill
and brake pedal pressed.
This mode ensures automatic engagement of the
most suitable gears for driving needs and
maximum fuel economy in terms of consumption.
In this position, the transmission shifts the gears
automatically, selecting the most suitable for
forward driving among those available as you go.
In this way the vehicle's optimal driving character
-
istics are provided for all conditions.
AutoStick
In the case of frequent shifting (e.g. for sport
driving, when the vehicle is driven with a heavy
load, on slopes, when towing heavy trailers), it is
recommended to use the AutoStick (sequential
shifting) mode to select and keep a lower fixed
ratio.
In these conditions, the use of a lower gear
improves vehicle performance and prevents
overheating.
It is possible to shift from DRIVE (D) mode to
AutoStick mode regardless of vehicle speed.
Activation
Starting from DRIVE (D) mode, to activate the
sequential drive mode, move the gear selector to
the left (– and + indication of the trim). The gear
engaged will be shown on the display. Shifting is made by moving the gear selector
forward, toward symbol – or backward, toward
symbol +.
Steering Column Mounted Shift Paddles —
If Equipped
The gear can be manually shifted also by using
the paddles behind the steering wheel, pull the
right paddle (+) toward the steering wheel and
release it to engage a higher gear, perform the
same operation with the left paddle (-) to engage
a lower gear.
Steering Column Mounted Shift Paddles

NOTE:
If only one manual shift is necessary, the letter D
will remain on the display with the engaged gear
next to it.
CAUTION!
Before moving the transmission gear
selector out of PARK, you must push the
ignition button to cycle from OFF position to
the ACC position, and also press the brake
pedal. Otherwise, damage to the gear
selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.
WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a collision.

Deactivation
To deactivate the sequential driving mode, bring
the gear selector back in position DRIVE (D)
("automatic" driving mode).

NOTE:

To select the correct gear for maximum
deceleration (engine brake), keep the gear
paddle pulled (–): the transmission goes to
an operating mode in which the vehicle can
slow down easily.
The vehicle will keep the gear selected by the
driver until the safety conditions allow it.
This means, for example, that the system will
try to prevent the engine from switching off,
automatically downshifting if the engine speed
is too low.
AUTOMATIC TRANSMISSION LIMP HOME
M
ODE
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this condition, the transmission stays in
FOURTH gear, regardless of the selected gear.
Positions PARK (P), REVERSE (R) and
NEUTRAL (N) still work.
The symbol might light up in the instrument
cluster.
Temporary failure
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK (P), if
possible. If not, shift the transmission to
NEUTRAL (N).
3. Push and hold the ignition until the engine turns off.
4. Wait for about 10 seconds, then restart the engine.
5. Shift into the desired gear range. If the problem is no longer detected, the transmis -
sion will return to normal operation.

NOTE:
Even if the transmission can be reset, we recom -
mend that you visit an authorized dealer at your
earliest possible convenience. An authorized
dealer has diagnostic equipment to determine if
the problem could reoccur. If the transmission
cannot be reset, service is required at an autho -
rized dealer.
BRAKE TRANSMISSION SHIFT INTERLOCK
(BTSI) S
YSTEM
This vehicle is equipped with a BTSI that holds the
gear selector in PARK (P) unless the brakes are
applied.
This system prevents you from moving the gear
selector from position PARK (P) unless the brakes
are applied.
To shift the transmission out of PARK (P), the
ignition must be cycled to the ON/RUN position
(engine running or not) and the brake pedal must
be pressed.
Brake Transmission Shift Interlock Disabling
Only if strictly necessary (e.g. pushing the vehicle,
conveyor vehicle washing systems), place the
vehicle in the NEUTRAL (N) position when
stopping the engine. See the following steps:
1. Bring the vehicle to a standstill.
2. Place the transmission in the NEUTRAL (N)
position.
3. Push the ignition button for at least three seconds.
The automatic activation of PARK (P) when the
engine is stopped can also be deactivated on the
Information and Entertainment system by
selecting the following functions on the main
menu: "Settings", "Driver Assistance" and
"Automatic Parking Brake".
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

IMPORTANT NOTES
Failure to comply with the following may damage
the transmission:
Shift into PARK (P) mode only with the vehicle
at a standstill.
Select REVERSE (R) mode, or pass from
REVERSE to another mode only with the
vehicle at a standstill and engine idling.
Do not change between PARK (P), REVERSE
(R), NEUTRAL (N) or DRIVE (D) modes with
engine running at a speed above idling.
Before activating any transmission operating
mode, fully press the brake pedal.
WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and your foot is
firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always apply the parking brake, shift
the transmission into PARK, and turn the
ignition OFF. When the ignition is in the OFF
position, the transmission is locked in PARK,
securing the vehicle against unwanted
movement.
When leaving the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allowing
children to be in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the
transmission gear selector.
WARNING!
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and
do not leave the ignition in the ON/RUN or
ACC position. A child could operate power
windows, other controls, or move the vehicle.
CAUTION!
Only engage the gear with engine at idling
while fully pressing the brake pedal. If the
transmission temperature exceeds the
normal operating limits, the transmission
control unit may change the gear
engagement order and reduce the drive
torque. If the transmission overheats, it
could operate incorrectly until it cools down.
When using the vehicle with extremely low
external temperatures, the transmission
operation may change depending on the
engine and transmission temperature, as
well as vehicle speed. Activation of the
torque converter clutch and of the EIGHTH
gear is inhibited until the transmission oil is
correctly warmed up. Complete operation of
the transmission will be enabled as soon as
the fluid temperature reaches the
predefined value.
WARNING!

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

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
adjustment 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.
Metric Speed (km/h)
Pushing the SET switch once will result in a
1 km/h speed adjustment. Each subsequent
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 measure -
ment set on the radio system. Refer to the Infor -
mation and Entertainment System Owner’s
Manual for more information.
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass 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.
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 returning to the previously set speed, you
must accelerate to a speed close to the set
speed, then push and release the RES button.
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
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.

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 106
When the conditions shown in the “Activating
Adaptive Cruise Control (ACC)” section occur

Ú
page 106
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.
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.
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.

ENABLING AND DISABLING PARKSENSE
For vehicles only equipped with rear sensors, to
turn the system off, push the ParkSense button
located to the left of the headlight switch. The
indicator light within the button will illuminate
when the system is turned off. Pushing the button
a second time will turn the system back on, and
the indicator light will turn off.ParkSense System On/Off Button
For vehicles equipped with front and rear
sensors, to turn the front parking sensors off,
push the ParkSense button located to the left of
the headlight switch. The indicator light within the
switch will illuminate when the system is turned
off. Pushing the button a second time will turn the
front sensors back on, and the indicator light will
turn off.

NOTE:
Deactivation of both the front and rear parking
sensors can only be done through the radio
system. The indicator light within the ParkSense system
switch will also be on in case of system failure. If
the switch is pushed with a system failure, the
indicator light will flash for approximately five
seconds. The light will then stay on constantly.

NOTE:
When the ignition is placed in the ON/RUN posi
-
tion, the ParkSense system keeps the last state
when the engine was stopped (activated or deac -
tivated) in its memory.
PARKSENSE WARNING DISPLAY
Parking sensor faults, if any, will be indicated
when REVERSE is engaged by a message on the
instrument cluster display

Ú
page 74.
In case of system failure, a dedicated message
appears on the instrument cluster for about
five seconds.
Cleaning The Front Or Rear Sensors : If the
display shows a message requiring the
sensors to be cleaned, make sure that the
outer surface and the underside of the front
and rear bumpers are free of debris (e.g. snow,
mud, ice, etc.). Once these areas are clear,
place the ignition in the OFF position, then
return it to ON/RUN. If the message is still
displayed, contact an authorized dealer.
Audio System Not Available : If the display
shows a message that the audio system is not
available, it means that the acoustic signal will
be emitted by the instrument panel, and not
through the vehicle’s speakers.
OPERATION WITH A TRAILER
The operation of the ParkSense system is
automatically deactivated when a trailer’s
electrical connector is plugged into the vehicle.
The sensors are automatically reactivated when
the electrical connector is removed.
WARNING!
Before using the ParkSense system, it is
strongly recommended that the ball mount
and hitch ball assembly be disconnected
from the vehicle when the vehicle is not used
for towing. Failure to do so can result in injury
or damage to vehicles or obstacles because
the hitch ball will be much closer to the
obstacle than the rear fascia when the
vehicle sounds the continuous tone. Also, the
sensors could detect the ball mount and
hitch ball assembly, depending on its size
and shape, giving a false indication that an
obstacle is behind the vehicle.
Drivers must be careful when backing up
even when using the ParkSense system.
Always check carefully behind your vehicle,
look behind you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before
backing up. You are responsible for safety
and must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.

Engagement/Disengagement
The system may be disengaged (and engaged
again) in the “Driver Assistance” menu of the
Information and Entertainment system.
The system can be deactivated even with the
ignition device in the ON position.

NOTE:
The system status can be changed with car at a
standstill only.
Select from three operating modes:
Warning And Braking: the system (if active), in
addition to the visual and audible warnings,
provides limited braking, automatic braking
and additional assistance in the braking stage,
where the driver does not brake sufficiently in
the event of a potential frontal impact.
Only Warning : the system (if active), does not
provide limited braking, but guarantees
automatic braking or additional assistance in
the braking stage, where the driver does not
brake at all or not sufficiently in the event of a
potential frontal impact.
Disabled : the system does not provide visual
and audible warnings, limited braking,
automatic braking or additional assistance in
the braking stage. The system will therefore
provide no indication of a possible collision.
Activation/Deactivation
The Forward Collision Warning system is
activated whenever the engine is started
regardless of what is shown on the radio system.
Following a deactivation, the system will not warn
the driver about the possible collision with a
preceding vehicle, regardless of the setting
selected in the radio system.

NOTE:
Each time the engine is started, the system is
activated regardless of what setting was selected
when the engine was turned off.
This function is not active at a speed lower than
4 mph (7 km/h) or higher than 124 mph
(200 km/h).
The system is active:
Each time the engine is started
When feature is selected within the radio
system
When the ignition is in the ON position
When the vehicle speed is between 2 mph
(4 km/h) and 124 mph (200 km/h)
When the front seat belts are fastened
The Alfa DNA selector is not in RACE position
(if equipped)

NOTE:
If the seat belts of the front seats are not correctly
fastened, the system will not intervene on the
braking system (only audible and visual signals
will be provided).
Changing The System Sensitivity
The sensitivity of the system can be changed
through the Information and Entertainment
system menu, choosing from one of the following
three options: "Near", "Medium" or "Far".
Refer to the description in the Information and
Entertainment system Supplement for how to
change the settings.
The default setting is "Medium". With this setting,
the system warns the driver of a possible collision
with the vehicle in front when that vehicle is at a
standard distance, between that of the other two
settings. With the system sensitivity set to "Far", the
system will warn the driver of a possible collision
with the vehicle in front when that vehicle is at a
greater distance, thus providing the possibility of
acting on the brakes more lightly and gradually.
This setting provides the driver with the maximum
possible reaction time to prevent a potential
collision.

NOTE:
The “Far” setting may result in a greater number
of FCW possible collision warnings experienced.
With the option set to "Near", the system will alert
the driver of a possible collision with the vehicle
in front when that vehicle is close. This setting
offers the driver a lower reaction time compared
to the "Medium" and "Far" settings, in the event of
a potential collision, but permits more dynamic
driving of the vehicle.

NOTE:
The “Near” setting may result in a lesser number
of FCW possible collision warnings experienced.
The system sensitivity setting is kept in the
memory when the engine is turned off.
System Limited Operation Warning
If a dedicated message is displayed, a condition
limiting the system operation may have occurred.
The possible reasons of this limitation are
something is blocking the camera view or a fault.
If an obstruction is signaled, clean the area of the
radar on the front fascia/bumper, and the
camera area on the windshield.
If a fault in the system is occurring, it will still be
possible to drive the vehicle normally, but
automatic braking will not be available in the
event of an impending collision.

Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the warning light in the
instrument cluster will display alongside the
dedicated messages, the system will highlight the
tire or tires with insufficient pressure graphically,
and an acoustic signal will be emitted.In this case, stop the vehicle, check the inflation
pressure of each tire, and inflate the necessary
tire or tires to the correct cold inflation pressure
value, shown on the display or in the dedicated
TPMS menu.
TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75 seconds,
and then remain on solid. The system fault will
also sound a chime. If the ignition is cycled, this
sequence will repeat, provided that the system
fault still exists. The TPMS Warning Light will turn
off when the fault condition no longer exists. A
system fault can occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Packed snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
After the punctured tire has been repaired with
the original tire sealant contained in the tire kit,
the previous condition must be restored so that
the warning light is off during normal driving.
TPMS Deactivation
The TPMS can be deactivated by replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have TPMS
sensors, such as when installing winter wheel
and tire assemblies on your vehicle. To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
System (TPMS) sensors. Then, drive the vehicle
for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“SERVICE TPM SYSTEM” message and then
display dashes (--) in place of the pressure values.
Beginning with the next ignition switch cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster. Instead, dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPMS sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds
and then turn off. The instrument cluster will
display the “SERVICE TPM SYSTEM” message
and then display pressure values in place of the
dashes. On the next ignition switch cycle the
“SERVICE TPM SYSTEM” message will no longer
be displayed, as long as no system fault exists.

NOTE:

The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS
pressures and warning have been
established for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPMS
sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
Original Equipment Manufacturer (OEM)
wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
