ACTIVE SAFETY
SYSTEMS
The vehicle may be equipped with the
following active safety devices:
Anti-Lock Braking (ABS) System
Drive Train Control (DTC) System
Electronic Stability Control (ESC)
System
Traction Control System (TCS)
Panic Brake Assist (PBA) System
Hill Start Assist (HSA) System
Dynamic Steering Torque (DST)
System
Active Torque Vectoring (ATV)
System
For the operation of the systems, see
the following pages.
Anti-Lock Braking (ABS)
System
An integral part of the braking system,
the ABS prevents one or more wheels
from locking and slipping in all road
surface conditions, regardless 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 emergency 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.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
capability. Installation of such equipment
should be performed by qualified
professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead to
a collision. Pumping makes the stopping
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
efficiency beyond that afforded by the
condition 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
reckless or dangerous manner that could
jeopardize the user’s safety or the safety of
others.
Drive Train Control
(DTC) System — If
Equipped
Some models of this vehicle are
equipped with an All-Wheel Drive
system (AWD), which offers an optimal
drive for countless driving conditions
and road surfaces. The system reduces
the slipping of the tires to a minimum,
automatically redistributing the torque
to the front and rear wheels as needed.
To maximize fuel savings, the vehicle
with AWD automatically passes to
rear-wheel drive (RWD) when the road
96
SAFETY

and environmental conditions are such
that they wouldn't cause the tires to
slip. When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD
mode.
The driving mode, RWD or AWD, is
shown on the instrument cluster
display.
Note:If the system failure symbol
switches on, after starting the engine or
while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently, it
is recommended to carry out the
maintenance operations.
Electronic Stability
Control (ESC) System
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the car to determine the path that
the driver intends to follow and
compares it with the car’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.
Oversteer occurs when the car is
turning more than it should according
to the angle of the steering wheel.
Understeer occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
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.
Warning!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESC
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
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.
Traction Control System
(TCS)
The system automatically operates in
the event of slipping, loss of grip on wet
roads (hydroplaning), 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.
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.
The PBA system is deactivated when
the brake pedal is released.
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.
Hill Start Assist (HSA)
System
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
Uphill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and
transmission in neutral or gear other
than reverse engaged;
Downhill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and reverse
gear engaged.
When setting off, 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.
When two seconds without starting
have elapsed, the system is
automatically deactivated, 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 car.
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.

SAFETY

Dynamic Steering
Torque (DST) System
The DST function uses the integration
of the ESC system with the electric
power steering to increase the safety
level of the whole vehicle.
In critical situations (braking on surfaces
with different grip conditions), the ESC
system controls the steering through
the DST function to implement an
additional torque contribution on the
steering wheel in order to suggest the
most correct maneuver to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
Note:
The DST feature is only meant to help
the driver realize the correct course of
action through small torques on the
steering wheel, which means the
effectiveness of the DST feature is
highly dependent on the drivers
sensitivity and overall reaction to the
applied torque. It is very important to
realize that this feature will not steer the
vehicle, meaning the driver is still
responsible for steering the vehicle.
Active Torque Vectoring
(ATV) System
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.
Given that, in a turn, the external
wheels of the car travel more than the
internal ones and therefore turn faster,
sending a higher thrust to the external
rear wheel allows for the car to be more
stable and to not suffer an "understeer"
condition. Understeer occurs when the
vehicle is turning less than appropriate
for the steering wheel position.
AUXILIARY DRIVING
SYSTEMS
The vehicle can feature the following
auxiliary driving systems:
Blind Spot Monitoring (BSM)
Forward Collision Warning (FCW)
Tire Pressure Monitoring System
(TPMS)
For the operation of the systems, see
the following pages.
Blind Spot Monitoring
(BSM) System
The Blind Spot Monitoring (BSM)
system uses two radar sensors, located
in the rear bumper (one for each side),
to detect the presence of vehicles
(vehicles, trucks, motorcycles, etc.) in
the rear side blind spots of your vehicle.

broken, damaged, worn or have moved
from their correct fitting position. If any
of these things occur, contact your
authorized dealer.
Open welding or loose connections
may permit exhaust gas to enter the
passenger compartment.
Check the exhaust system each time
the vehicle is raised for lubrication or oil
change operations. Replace the
components if necessary, contact your
authorized dealer.
Performance
This vehicle is equipped with an engine
capable of delivering exceptionally fast
acceleration and speed:
Peak power: 505 HP at 6500 rpm.
Peak torque: 443 ft-lbs at
2500–5000 rpm.
Top speed: 190 mph (307 km/h).
Acceleration from 0 to 60 mph (0 to
100 km/h): 3.9 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 discovering 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 component
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 condensation 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 your authorized
dealer which exclusively has the skills
needed for the repair 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 your 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. For more information,
see the “Checking Levels” section in
the “Servicing And Maintenance”
chapter.
Have the car inspected at your
authorized dealer.
Remember that the car was not
designed to be driven exclusive on the
race track and that this use increases
stress and component wear.
