Preheating the carbon ceramic material brake
discs
The brake discs must be warmed up to make
them fully efficient. Perform the following
procedure to achieve optimal efficiency:
Brake nine times from 80 mph to 18 mph
(130 km/h to 30 km/h) with deceleration
equal to 0.7g (the longitudinal acceleration
value is shown on the instrument cluster
display by setting RACE mode and selecting
the “Performance” page) with 20 second
intervals between brake applications; keep the
car at a speed comprised between 37 mph
and 62 mph (60 km/h and 100 km/h) and do
not brake for 4 minutes to allow the brakes to
cool down.
Then brake three times from 124 mph to
18 mph (200 km/h to 30 km/h) with
deceleration equal to 1.1g (ABS operation)
with 30 second intervals between brake
applications; keep the car at a speed
comprised between 37 mph and 62 mph
(60 km/h and 100 km/h) and do not brake for
5 minutes to allow the brakes to cool down.

HILL DESCENT CONTROL (HDC)
S
YSTEM — IF EQUIPPED
The HDC function is an integral part of the
Electronic Stability Control (ESC) system, keeping
the vehicle at a constant speed while descending
a hill by actively controlling the brakes.
HDC aims to create vehicle stability and safer
driving in various situations, including poor grip
conditions and steep descents.
The system has three different modes:
Off: the system is deactivated
Enabled: the system is enabled and ready to
intervene when the activation conditions are
met
Active: the system actively controls the vehicle
speed Enabling The System
To enable the system, push the HDC switch
located on the steering wheel.
HDC Switch
The system is enabled if the car speed is below
20 mph (30 km/h). The system stays enabled
until the car speed reaches 37 mph (60 km/h),
the system is disabled at speeds above 37 mph
(60 km/h).
Activation of the HDC system is indicated by the
white icon appearing in the instrument cluster
display.
HDC Symbol Activation Of The System
Once enabled, the HDC system will activate
automatically if the vehicle is driven on a downhill
slope with sufficient gradient, greater than 8%.
The speed set for the HDC system can be
adjusted using the SET switch located on the
steering wheel.
HDC Speed SET Switch
Once the desired speed has been reached,
release the SET switch and the HDC system will
maintain the set speed. After set speed is
established, the HDC system will automatically
brake to keep the vehicle at the set speed if the
accelerator pedal is released and the vehicle gets
close to the set speed.
It is possible to reduce the set speed with the
brake pedal. When the pedal is released, the
system will adjust the set speed to the new
current speed.
Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and
size or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade ESC
performance. Any vehicle modification or
poor vehicle maintenance that reduces the
effectiveness of the ESC system can
increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.
WARNING!

SAFETY
138
NOTE:
If the vehicle’s speed exceeds 6 mph (10 km/h),
but remains below 37 mph (60 km/h) and the
accelerator pedal is released, as soon as the
vehicle gets close to the set speed the HDC
system will automatically brake to keep the
vehicle at the set speed.
The driver can cancel HDC system intervention at
any time by pressing the accelerator pedal.
System Deactivation
The HDC system will be deactivated, but remain
available, if any of the following conditions are
met:
The vehicle is traveling on a downhill slope
with a gradient less than 8%, on a level
surface, or on an uphill grade.
PARK (P) mode is engaged.
Disabling The System
The system is disabled if any of the following
conditions are met:
The HDC switch is pressed.
Cruise Control/Adaptive Cruise Control is
activated.
A vehicle speed of 37 mph (60 km/h) is
exceeded.
System deactivation is shown by the icon on
the display turning off.
HILL START ASSIST (HSA) SYSTEM
HSA is an integral part of the Electronic Stability
Control (ESC) system that facilitates starting on
slopes, activating automatically in the following
cases:
Uphill: the vehicle is stationary on a road with
a gradient higher than 5%, the engine is
running, the brake is pressed, and the
transmission is in NEUTRAL (N) or a gear other
than REVERSE (R) is engaged.
Downhill: the vehicle is stationary on a road
with a gradient higher than 5%, the engine is
running, the brake is pressed, and the
transmission is in REVERSE.
When starting to move forward from a complete
stop, the ESC system control unit maintains the
braking pressure on the wheels until the engine
torque necessary for starting is reached, or in any
case for a maximum of two seconds, allowing
your right foot to be moved easily from the brake
pedal to the accelerator.
The system will automatically deactivate after
two seconds without starting, gradually releasing
the braking pressure. During this release stage, it
is possible to hear a typical mechanical brake
release noise, indicating the imminent
movement of the vehicle.
PANIC BRAKE ASSIST (PBA) SYSTEM
The PBA system is designed to improve the
vehicle’s braking capacity during emergency
braking.
The system detects emergency braking by
monitoring the speed and force with which the
brake pedal is pressed, and consequently applies
the optimal brake pressure. This can reduce the
braking distance; the PBA system therefore
complements the ABS.
Maximum assistance from the PBA system is
obtained by pressing the brake pedal very
quickly. In addition, the brake pedal should be
pressed continuously during braking, avoiding
intermittent presses, to get the most out of the
system. Do not reduce pressure on the brake
pedal until braking is no longer necessary.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for main -
taining a safe vehicle speed.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement.
It is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, 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 warnings can result in a collision
or serious personal injury.
22_GU_OM_EN_USC_t.book Page 138
SAFETY
142
Sensors
The system uses radar sensors, located in the
rear fascia/bumper, to detect the presence of
vehicles (cars, trucks, motorbikes, etc.) in the
rear side blind spots of the car.
The sensors are activated when any forward gear
is engaged at a speed higher than about 6 mph
(10 km/h), or when REVERSE (R) is engaged.
The sensors are temporarily deactivated when
the car is stationary and in PARK (P).
The detection area of the system covers about a
lane on both sides of the car around 10 ft
(3 meters).This area begins from the door mirror and
extends for about 20 ft (6 meters) towards the
rear part of the car.
When the sensors are active the system monitors
the detection areas on both sides of the car and
warns the driver about the possible presence of
cars in these areas.
Rear Sensor Location
While driving, the system monitors the detection
zone in three different situations:
when you are being overtaken by a vehicle;
when you are overtaking a vehicle;
when a vehicle approaches from the side;
to check if it is necessary to intervene in order to
keep the vehicle inside the lane on both sides.
NOTE:
The system does not signal the presence of fixed
object (e.g. safety barriers, poles, walls, etc.).
However, in some circumstances, the system
may activate in the presence of these
objects.This is normal and does not indicate a
system malfunction. The system does not warn the driver about the
presence of cars coming from the opposite direc
-
tion, in the adjacent lanes.
Activation/Deactivation
The system can be activated/deactivated using
the “Driver Assistance” menu in the radio system.
Select signal type, strength levels and sensitivity.
NOTE:
Vehicles with an active system will display the
following screen, on the radio system.
ABSA Menu Screen
System Intervention
The system intervenes in the following
conditions:
the turn signals have been activated;
there is a vehicle in the adjacent lane on the
same side of the turn signal (blind spot area);
lane lines are not correctly detected;
the driver tries to change lanes intentionally.
Applying a torque that corrects the steering
wheel alignment does not always prevent an
accident. It is always the driver's responsi -
bility to steer, brake or accelerate, especially
after the ABSA system warning or after the
steering wheel torque intervention. 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.
In some cases, the system could apply an
improper torque to the steering wheel. This
application can be interrupted at any time by
turning the steering wheel in the opposite
direction.
WARNING!
22_GU_OM_EN_USC_t.book Page 142
143
If the system detects the presence of a vehicle in
the rear side blind spots of the car, it applies a
torque on the steering wheel (if it has been set
through the “Settings” menu of the radio system),
in order to warn the driver of the need to keep the
car inside the lane and thus avoid collisions with
other vehicles.
The application of torque and vibration is
however only available with car speed between
37 mph (60 km/h) and 110 mph (180 km/h).
The application of torque, as well as of the
vibration, is suppressed/inhibited if:
The torque given by the driver of the steering
wheel is high
Lateral acceleration is high
The trailer is connected to the correct control
module
At least one hand is not detected on the
steering wheel for longer than a specific time
The turn signal is turned off
NOTE:
The steering wheel torque is not applied if the
system is unable to detect a lane and if the turn
signal for the appropriate side has not been
switched on.
The steering wheel detects the presence of the
driver’s hands by a capacitive sensor installed in
the steering wheel and by the applied torque
measured on the steering column.System Availability
Aggressive driving of the car, or driving on the
median lines, will prevent the correct operation of
the system.
In case of intervention of the stability and braking
systems (FCW, ESC, ABS) they will prevent the
system from operating.
Lane change will disable the system for a certain
period of time.
The road must also comply with some specific
characteristics, such as:
Maximum/minimum lane width.
Clearly identified and defined double yellow
lines and, for a limited period of time, a lane
with a single demarcation line.
NOTE:
In some cases, for a limited period of time, the
system may be activated by a lane with a single
median line.
In cases of good road surface conditions, the
system could correctly recognize other types of
valid lane markings (e.g. road edges, sidewalks,
etc.).
Hand Presence On The Steering Wheel Detection
The system is able to detect the presence of the
driver’s hands on the steering wheel.
When the system does not detect the presence of
hands on the steering wheel for 0 to 6 seconds,
the following screen will be displayed on the
instrument cluster display. No acoustic warning
will be emitted in this case.
Hand Presence On The Steering Wheel Not
Detected Display (Up To 6 Seconds)
When the system does not detect the presence of
hands on the steering wheel from 6 to 15 sec-
onds, the following screen will be displayed on
the instrument cluster display. A short acoustic
signal will sound if hands are not detected on the
steering wheel for 6 to 12 seconds. A continuous
signal will sound if hands are not detected on the
steering wheel for 12 to 15 seconds.
Hand Presence On The Steering Wheel Not Detected Display (6 To 15 Seconds)
22_GU_OM_EN_USC_t.book Page 143
SAFETY
144
After 15 seconds with the hands removed from
the steering wheel, the LKA system will be
deactivated and a dedicated message will be
shown on the instrument cluster display. A short
acoustic signal will sound in this case.
In any of the situations above where the hands
are removed from the steering wheel for more
than 6 seconds, it is necessary to reposition the
hands on the steering wheel.
Changing The System Sensitivity
The system's sensitivity can be set through the
radio system. Select the “Driver Assistance”
menu and then select “Comfort”. Sensitivity
“High” or “Low” can be selected.
Rear Cross Path Detection (RCP) System
The Rear Cross Path Detection (RCP) system
assists the driver during reverse maneuvers in
the case of reduced visibility.
When the ABSA system is active, the RCP system
monitors the rear detection areas on both sides of
the vehicle to detect objects moving towards the
sides of the vehicle at a minimum speed between
0.6 mph and 2 mph (1 km/h and 3km/h) from
objects moving at a maximum speed of 22 mph
(35 km/h).
These are generally occurrences that happen in
parking areas.
The system activation is signaled to the driver by
means of a visual and audible warning.
NOTE:
If the sensors are covered by objects or vehicles,
the system may not work as intended.Changing The System Sensitivity

DRIVER ATTENTION ASSIST (DAA)
S
YSTEM — IF EQUIPPED
The Driver Attention Assist (DAA) system detects
when the driver is feeling fatigued and warns the
driver to pull over and take a break.
To Activate/Deactivate
The DAA system can be activated and
deactivated through the radio system by
selecting the following in order:
1. “Driver Assistance”
2. “Driver Attention Assist”
System Intervention
Using information from the front camera, the
system implements two operating logics:
The first operating logic takes the driving style
into account, observing the road and detecting
to what extent the driver can continue driving
with few lane crossing events.
The second operating logic measures the time
spent behind the wheel with the vehicle speed
above 40 mph (60 km/h) and below 110 mph
(180 km/h). If the “Standard” option is
selected, in these conditions, the “Dozy Driver”
message may appear after three hours of
driving. If the “Early” option is selected and
these conditions occur, the “Dozy Driver”
message will be displayed after two hours of
driving.
NOTE:
If the conditions described above are not
detected continuously during the entire driving
period, the “Dozy Driver” message may be
displayed later than two or three hours. If the
driving style indicates that the driver is unable to
follow the road trajectory and respect the hori-
zontal lane markings, the red symbol will appear
on the instrument cluster display to suggest that
the driver should stop for a break. An audible
signal will also sound.
If the driver accepts the suggestion provided by
the system by pushing the MENU button on the
multifunction lever, the message will disappear
from the display and the symbol will be displayed
in the dedicated area of the instrument cluster
display until the next engine shutdown. WARNING!
The DAA System is an aid for driving and does
not relieve the driver of the responsibility of
driving the vehicle. If you experience fatigue
while driving, pull over safely for a break
without waiting for the DAA to intervene. Only
return to the road when you are in the right
physical and mental condition to prevent
endangering yourself and other drivers.
22_GU_OM_EN_USC_t.book Page 144
145
If the driver ignores the warning provided by the
system and does not stop, the message will
continue to remain on the display, along with the
symbol.
NOTE:
In the event of a DAA system failure, an amber
symbol will appear in the instrument cluster
display along with a dedicated message.
If the ABS system activates, “ABS ACTIVE” will
display in place of the DAA symbol and will
remain active until the ABS system
deactivates.
DAA Warning Message
DAA Warning Icon Changing The System Sensitivity
The DAA system intervention sensitivity can be
adjusted through the radio system within the
“Driver Assistance” menu.
NOTE:
If “Race” mode (if equipped) is activated, the
DAA system will be automatically deactivated.
The system sensitivity cannot be changed in
the event of a camera system failure.
FORWARD COLLISION WARNING PLUS
(FCW+) S
YSTEM — IF EQUIPPED
This is a driving assistance system composed of a
radar located behind the front fascia/bumper
and a camera located in the center of the
windshield.
Front Fascia/Bumper Radar Location Windshield Camera Location
In the event of an imminent collision, the system
intervenes by automatically applying the vehicle’s
brakes to prevent a collision or reduce its effects.
The system provides the driver with audible and
visual signals through specific messages on the
instrument cluster display.
Vehicle Brake Screen
22_GU_OM_EN_USC_t.book Page 145

When the front seat belts are fastened
The "Alfa DNA Pro" 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.
When the conditions limiting the system
functions end, this will go back to normal and
complete operation. Should the fault persist,
contact an authorized dealer.
System Failure Signaling
If the system turns off and a dedicated message
is shown on the display, it means that there is a
fault with the system.
In this case, it is still possible to drive the vehicle,
but you are advised to contact an authorized
dealer as soon as possible.
Radar Indication Not Available
If conditions are such that the radar cannot
detect obstacles correctly, the system is
deactivated and a dedicated message appears on the display. This generally occurs in the event
of poor visibility, such as when it is snowing or
raining heavily.
The function of this system can also be
temporarily reduced due to obstructions such as
mud, dirt or ice on the fascia/bumper. In such
cases, a dedicated message will be shown on the
display and the system will be deactivated. This
message can sometimes appear in conditions of
high reflectivity (e.g. tunnels with reflective tiles or
ice or snow). When the conditions limiting the
system functions end, it will go back to normal
and complete operation.
In certain cases, this dedicated message could
be displayed when the radar is not detecting any
vehicles or objects within its view range.
If atmospheric conditions are not the reason
behind this message, check if the sensor is dirty.
It could be necessary to clean or remove any
obstructions in the area.
If the message appears frequently, even in the
absence of atmospheric conditions such as snow,
rain, mud or other obstructions, contact an
authorized dealer for a sensor alignment check.
In the absence of visible obstructions, manually
removing the decorative cover trim and cleaning
the radar surface could be required. Have this
operation performed at an authorized dealer.
NOTE:
It is recommended that you do not install devices,
accessories or aerodynamic attachments in front
of the sensor or darken it in any way, as this can
compromise the correct functioning of the
system.
