"Natural" mode, depending on which mode
was selected before the engine was
stopped.
When the engine is started again, the
"RACE" mode selected previously is not
retained. The system will reactivate in
"Dynamic" mode.
ALFA ACTIVE SUSPENSION
(AAS) — IF EQUIPPED
The vehicle's electronic suspension manage-
ment system is aimed at optimizing the
vehicle's performance.
The system continuously monitors the
damping of the suspensions through the actu -
ator installed on each shock absorber. This
way, the calibration of the shock absorbers
can be adjusted to the conditions of the road
surface and to the dynamic conditions of the
vehicle, improving its comfort and road
holding.
The driver can choose, even while driving,
(only in “Dynamic” mode), between two types
of suspension calibration: a more sporty or a
more comfortable one.
By pushing the button, the system changes
the shock absorber calibration. Alfa Active Suspension Button
In case of a system failure, the symbol and
a dedicated message will be shown on the
instrument cluster display.
STOP/START SYSTEM
The Stop/Start system automatically shuts off
the engine during a vehicle stop if the required
conditions are met. Releasing the brake pedal
or accelerator pedal will automatically restart
the engine.
The function was developed to increase
vehicle efficiency by reducing fuel consump -
tion, gas emissions, and sound pollution.

NOTE:

When the Stop/Start system stops the engine,
the power steering is also disabled.
Operating Mode
Stopping The Engine

With the vehicle at a standstill and brake pedal
pressed, the engine switches off if the gear selector
is in a position other than REVERSE (R).
The system does not operate when the gear
selector is in REVERSE (R), in order to make
parking maneuvers easier.
In the event of stops uphill, engine switching off is
disabled to make the “Hill Start Assist” function
available (works only with running engine).

NOTE:
The engine can only be automatically stopped
after having run at about 6 mph (10 km/h). After
an automatic restart, the vehicle only needs to
exceed a speed of 0.3 mph (0.5 km/h) to stop
the engine.

Engine stopping is signaled by the symbol
lighting up on the instrument cluster display.
Restarting The Engine
To restart the engine, release the brake pedal
or, turn the steering wheel slightly (if
equipped).
With the brake pressed and the transmission
in automatic mode DRIVE (D), the engine will
restart by shifting to REVERSE (R), to PARK (P)
or to “AutoStick”

ParkSense System Usage Precautions

NOTE:

Some conditions may influence the perfor-
mance of the ParkSense system:
Reduced sensor sensitivity could be due to
the presence of ice, snow, mud, or thick
paint on the surface of the sensor.
The sensors may detect a false obstacle
(echo interference) due to mechanical inter -
ference, for example when washing the
vehicle or in extreme weather.
The signals sent by the sensors can be
altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems of
trucks or pneumatic drills) near the vehicle.
System performance can be influenced by
the position of the sensors. For example,
due to a change in the ride setting (caused
by wear to the shock absorbers or suspen -
sion), by changing tires, overloading the
vehicle or operations that require the
vehicle to be lowered.
Be sure not to place bumper stickers or
other adhesives over the sensors as this will
affect system performance.
The presence of a trailer hitch without a
trailer. This may interfere with the operation
of the parking sensors. Before using the
ParkSense system, it is recommended to remove or close the trailer hitch assembly
when the vehicle is not being used for
towing.
LANE DEPARTURE WARNING
(LDW) SYSTEM
Lane Departure Warning Operation
The Lane Departure Warning system uses a
forward looking camera located on the wind
-
shield to detect lane markings and measure
vehicle position within the lane boundaries.
When one or both lane limits are detected and
the vehicle passes over one without an acti -
vated turn signal, the system emits a visual as
well as an acoustic signal.
If the vehicle continues to go beyond the line
of the lane without any intervention from the
driver, the surpassed line will light up on the
display (left or right) to urge the driver to bring
the vehicle back into the limits of the lane.
CAUTION!
Projecting loads on the roof of the vehicle
may interfere with the correct operation of
the camera. Before starting, make sure
the load is correctly positioned in order
not to cover the camera operating range.
Do not cover the operating range of the
camera with stickers or other objects.
Do not tamper with nor operate on the
camera. Do not close the openings in the
aesthetic cover located under the interior
rearview mirror. In the event of a failure of
the camera, contact your authorized
dealer.
The camera may have limited or absent
operation due to weather conditions such
as: heavy rain, hail, thick fog, heavy snow,
formation of ice layers on the windshield.
Camera operation may also be compro -
mised by the presence of dust, condensa -
tion, dirt or ice on the windshield, by traffic
conditions (e.g. vehicles that are driving
not aligned with yours, vehicle driving in a
transverse or opposite way on the same
lane, bend with a small radius of curva -
ture), by road surface conditions and by
driving conditions (e.g. off-road driving).
Make sure the windshield is always clean.
Use specific detergents and clean cloths
to avoid scratching the windshield. The
camera operation may also be limited or
absent in some driving, traffic and road
surface conditions.
If the windshield must be replaced due to
scratches, chipping or breakage, contact
exclusively an authorized dealer. Do not
replace the windshield on your own. It is
advisable to replace the windshield if it is
damaged in the area of the camera.

the camera view, or a fault in the system.
If an obstruction is detected, clean the area of
the windshield by the interior rearview mirror.
Although the vehicle can still be driven in
normal conditions, the system may not func -
tion properly.
When the conditions limiting the system are
corrected, it will go back to normal operation.
Should a fault persist, contact an authorized
dealer.
System Failure Signaling
If the system turns off and appears on the
display, it means that there is a system fault.
In this case, it is still possible to drive the
vehicle, but you are advised to contact an
authorized dealer as soon as possible. CAUTION!
Projecting loads on the roof of the vehicle
may interfere with the correct operation of
the camera. Before starting, make sure
the load is correctly positioned, in order
not to cover the camera operating range.
If the windshield must be replaced due to
scratches, chips or breakage, contact an

Traffic And Road Conditions
High fuel consumption is caused by heavy
traffic, for instance when traveling in traffic
with frequent use of low gears or in cities with
many traffic lights. Winding mountain roads
and rough road surfaces also adversely affect
consumption.
Stops In Traffic
During prolonged stops (e.g. railway cross-
ings), turn off the engine.
Performance — Quadrifoglio
This vehicle is equipped with an engine
capable of delivering exceptionally fast accel -
eration and speed:
Peak power: 505 HP at 6,500 RPM.

Peak torque: 443 ft-lbs at 2,500–5,000 RPM.

Top speed: 176 mph (283 km/h).

Acceleration from 0 to 60 mph (0 to 100 km/h):
3.6 seconds.

For safe driving, it is essential, particularly
during the first days of use, to get to know the
car by driving carefully and gradually discov -
ering its performance.
Brakes
The car braking system may be available with
four carbon-ceramic material brake discs, one
on each wheel. In order to guarantee the maximum braking
capacity for the first use, Alfa Romeo performs
a "run-in" procedure for discs and pads directly
at the factory.
The use of carbon-ceramic material brake
discs guarantees braking features (better
deceleration/pedal load ratio, braking
distances, fading resistance) proportional to
the dynamic features of the car in addition to
considerably decreasing the unsprung compo
-
nent weight.
The materials used and the structural features
of the system could generate unusual noises
which have absolutely no adverse effect on
correct operation and reliability of the braking
system.
Greater pressure may need to be applied to
the brake pedal the first time to keep the same
braking capacities in presence of condensa -
tion or salt on the braking surfaces, for
example after washing or if the car is not used
for a long time.

NOTE:

Given the high technological level of this
system, any servicing on it must be performed
by an authorized dealer which exclusively has
the skills needed for the repair and mainte -
nance operations. In case of intensive, high-performance use of
the car, have the efficiency of the
carbon-ceramic material braking system
inspected as shown on the Maintenance Plan
at an authorized dealer.
Driving On Race Tracks
Before driving on a track using a racing style, it
is necessary to:
Attend a race track driving course.
Check the liquid levels in the engine
compartment
Ú

page 208.
Have the car inspected at an authorized
dealer.
Remember that the car was not designed to be
driven exclusively on the race track and that
this use increases stress and component
wear.

NOTE:

Quadrifoglio front brakes are equipped with
Non-Asbestos Organic (NAO) type pads. These
pads are NOT suitable for high thermal loads
(for example track use). If you want to use
vehicle on a track it is recommended to use
the optional CCM Brakes (Carbon Ceramic
Brake disc).
21_GU_OM_EN_USC_t.book Page 143

STARTING AND OPERATING

144

Preheating the carbon ceramic material brake
discs
The brake discs must be warmed up to make
them fully efficient. You are advised to 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 decel -
eration equal to 1.1g (ABS operation) with
30 second intervals between brake applica -
tions; 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.

SAFETY
This very important section describes the
safety systems that your vehicle may be
equipped with, and provides instructions on
how to use them correctly.
ACTIVE SAFETY SYSTEMS
The vehicle may be equipped with the
following active safety devices:
Anti-Lock Brake System (ABS)
Active Torque Vectoring (ATV) System
Dynamic Steering Torque (DST) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC) System
Hill Descent Control (HDC) System
Hill Start Assist (HSA) System
Panic Brake Assist (PBA) System
Traction Control System (TCS)
For system operation, see the following pages.
Anti-Lock Brake System (ABS)
An integral part of the braking system, the ABS
prevents one or more wheels from locking and
slipping in all road surface conditions, regard -
less of the intensity of the braking action. The
system ensures that the vehicle can be
controlled even during emergency braking,
allowing the driver to optimize stopping
distances. The system intervenes during braking when
the wheels are about to lock, typically in emer
-
gency braking or low-grip conditions where
locking may be more frequent.
The system also improves control and stability
of the vehicle when braking on a surface
where the grip of the left and right wheels
varies, such as in a corner.
The Electronic Braking Force Distribution
(EBD) system works with the ABS, allowing the
brake force to be distributed between the front
and rear wheels.
System Intervention
The ABS equipped on this vehicle is provided
with the "Brake-By-Wire", Integrated Brake
System (IBS), function. With this system, the
command given by pressing the brake pedal is
not transmitted hydraulically, but electrically.
Therefore, the light pulsation that is felt on the
pedal with the traditional system is no longer
noticeable.Active Torque Vectoring (ATV) System — If
Equipped
The dynamic drive control is used to optimize
and balance the drive torque between the
wheels of the same axles. The ATV system
improves the grip in turns, sending more drive
torque to the external wheel.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to
interference caused by improperly
installed or high output radio transmitting
equipment. This interference can cause
possible loss of anti-lock braking capa -
bility. Installation of such equipment
should be performed by qualified profes -
sionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead
to a collision. Pumping makes the stop -
ping distance longer. Just press firmly on
your brake pedal when you need to slow
down or stop.
The ABS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase braking or steering effi -
ciency beyond that afforded by the condi -
tion of the vehicle brakes and tires or the
traction afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped
vehicle must never be exploited in a reck -
less or dangerous manner that could jeop -
ardize the user’s safety or the safety of
others.
WARNING! (Continued)
21_GU_OM_EN_USC_t.book Page 145

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 thesystem. Do not reduce pressure on the brake
pedal until braking is no longer necessary.
The PBA system is deactivated when the brake
pedal is released.Traction Control System (TCS)
The TCS automatically operates in the event of
slipping, loss of grip on wet roads (hydro
-
planing), and acceleration on one or both drive
wheels on roads that are slippery, snowy, icy,
etc. Depending on the slipping conditions, two
different control systems are activated:
If the slipping involves both drive wheels,
the system intervenes, reducing the power
transmitted by the engine.
If the slipping only involves one of the drive
wheels, the Brake Limited Differential (BLD)
function is activated, automatically braking the wheel which is slipping (the behavior of
a self-locking differential is simulated). This
will increase the engine torque transferred
to the wheel which isn't slipping.
System Intervention
The intervention of the system is indicated by
the flashing of the ESC warning light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
AUXILIARY DRIVING SYSTEMS
The following auxiliary driving systems are
available in this vehicle:
Blind Spot Monitoring (BSM) — if equipped
Active Blind Spot Assist (ABSA) — if
equipped
Forward Collision Warning Plus (FCW+)
Tire Pressure Monitoring System (TPMS)
The vehicle may also be fitted with the
following driving assistance systems:
Driver Attention Assist (DAA)
Lane Departure Warning (LDW)
Lane Keeping Assist (LKA)
Highway Assist System (HAS)
Traffic Jam Assist (TJA)
Adaptive Cruise Control (ACC)
Intelligent Speed Control (ISC)
Traffic Sign Recognition (TSR)
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 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 or
serious personal injury.
WARNING!
The Panic Brake Assist (PBA) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. PBA cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities
of a PBA-equipped vehicle must never be
exploited in a reckless or dangerous
manner, which could jeopardize the user's
safety or the safety of others.

SAFETY

150

For the operation of the DAA, LDW, LKA, HAS,
TJA, ACC, ISC, or TSR systems, see
Ú
page 86.

NOTE:

When driving on two-way roads where there is
no lane dividing center line (e.g. on unpaved
roads), the use of the ABSA, HAS, TJA, and LKA
systems is strongly discouraged as the system
could detect the entire road as single-lane
dividing lines.

NOTE:

The driving assistance systems are designed
to aid in driving the car. The driver must always
maintain a sufficient level of attention to the
traffic and road conditions and control the
trajectory of the car.
Blind Spot Monitoring (BSM) System — If
Equipped
The BSM system uses radar sensors, located
in the rear fascia/bumper, to detect the pres -
ence of other vehicles in the rear side blind
spots of your vehicle.
Rear Sensor Location The system warns the driver about the pres
-
ence of other vehicles in the detection area by
illuminating the warning light located within
the door mirror on the side in which the other
vehicle was detected. If equipped, an audible
chime will also be heard to alert the driver (if
option is selected within the radio system).
BSM Indicator Light
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active.
Sensors
The sensors are activated when any forward
gear is engaged at a speed higher than
approximately 6 mph (10 km/h) or when
REVERSE is engaged.
The sensors are temporarily deactivated when
the vehicle is stationary or the vehicle is in
PARK.
The detection area of the system covers
approximately one lane on both sides of the
vehicle, which is around 9 ft (3 m). This area begins from the door mirror and
extends for approximately 19 ft (6 m) towards
the rear part of the vehicle.
When the sensors are active, the system moni
-
tors the detection areas on both sides of the
vehicle and warns the driver about the
possible presence of vehicles in these areas.
While driving, the system monitors the detec -
tion 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 whether it is necessary to send a
signal to the driver on both sides.

NOTE:

The system does not alert the driver of the
presence of fixed objects (e.g. safety
barriers, poles, walls, etc.). However, in
some circumstances, the system may acti -
vate in the presence of these objects. This is
normal and does not indicate a system
malfunction.
The system does not alert the driver about
the presence of vehicles coming from the
opposite direction, in the adjacent lanes.
If a trailer is hitched to the car, the system
automatically deactivates.
21_GU_OM_EN_USC_t.book Page 150

SAFETY

152

Operating Mode
The system may be activated/deactivated via
the radio system. To access the function,
select the following items on the main menu in
sequence:
1. “Driving Assistance”
2. “Blind Spot Alert”
“Blind Spot Alert”, “Visual” Mode
When the system is enabled, the warning light
within the door mirror on the side of the
detected object illuminates.
The visual warning on the mirror will blink if the
driver activates the turn signals, indicating a
lane change.
The warning light will be constant if the driver
stays in the same lane.
“Blind Spot Alert” Function Deactivation
When the system is deactivated (“Blind Spot
Alert” mode off), the BSM or RCP systems will
not emit an audible or a visual warning.
The BSM system will store the operating mode
that was active when the engine was stopped.
Each time the engine is started, the operating
mode stored previously will be recalled and
used
Ú
page 268.
Active Blind Spot Assist (ABSA) System — If
Equipped
The ABSA system is to help avoid/limit lateral
collisions with cars coming from adjacent lanes changing the vehicle’s trajectory in order
to try to keep it in the detected lane.
The system warns the driver about the pres
-
ence of other vehicles in the detection area by
illuminating the warning light located within
the door mirror on the side in which the other
vehicle was detected and by means of an
acoustic signal and/or vibration on the
steering wheel and/or counter-steering torque
on the steering wheel (if the respective item on
the “Driver Assistance” menu is set up and
then “Safety” is selected on the radio system).
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active (the warning light comes on
even if the system is activated through the
radio system menu).
ABSA Indicator Light 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.
WARNING!
The accident risk persists despite the
application of torque to the steering wheel
by the ABSA system.
Applying a torque that corrects the
steering wheel alignment does not always
prevent an accident. It is always the
driver's responsibility to steer, brake or
accelerate, especially after the ABSA
system warning or after the steering wheel
torque intervention. The driver is respon
-
sible for ensuring that there are no pedes -
trians, 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 turning the steering wheel in the
opposite direction.
