NOTE:

Moving the RES/SET switch downward
allows you to adjust the speed according to
the selected unit of measurement ("U.S." or
"Metric") set on the radio system. Refer to
the Information and Entertainment System
Owner’s Manual Supplement for further
information.
When the unit of measurement is set to
Metric, pushing and holding the RES/SET
switch will adjust the speed in 10 km/h
increments.
By keeping the accelerator pedal pressed,
the vehicle can continue to accelerate
beyond the set speed. In this case, use the
RES/SET switch to set the speed to the
vehicle’s current speed.
When you push the RES/SET button to
reduce the speed, the braking system inter-
venes automatically if the engine brake
does not slow the vehicle down sufficiently
to reach the set speed. The device holds the
set speed uphill and downhill; however a
slight variation is entirely normal, particu -
larly on slight inclines.
The transmission could shift to a lower gear
when driving downhill, or when acceler -
ating. This is normal and necessary to main -
tain the set speed.
The system will disable while driving if the
brakes overheat.
To Resume

Once the system has been canceled but not
deactivated, to resume a previously set speed,
simply push the RES/SET switch upward and
remove your foot from the accelerator to recall it.

The system will be set to the last stored speed.
Setting The Distance Between Vehicles
The distance between your vehicle and the
vehicle ahead may be set to one bar (short),
two bars (medium), three bars (long), or four
bars (maximum). Distance Icons
The distances from the vehicle ahead are
proportional to speed.
The interval of time with relation to the vehicle
ahead remains constant and varies from one
second (for the short distance one-bar setting)
to two seconds (for the maximum distance
four-bar setting).
The set distance is shown on the display by a
dedicated icon.
The setting is four bars (maximum) the first
time the system is used. After the distance has
been modified by the driver, the new distance
will be stored even if the system is deactivated
and reactivated.
WARNING!
The Resume function should only be used if
traffic and road conditions permit.
Resuming a set speed that is too high or too
low for prevailing traffic and road conditions
could cause the vehicle to accelerate or
decelerate too sharply for safe operation.
Failure to follow these warnings can result
in a collision and death or serious personal
injury.

If several obstacles are detected simultane-
ously in the front and rear area, the display will
show all of them, regardless of the area in
which they were detected.
It is not possible to exit from the display screen
while the vehicle is in REVERSE.
Acoustic Signal
In the presence of an obstacle at the front or
the rear of the vehicle, an acoustic signal with
variable frequency will sound:
The acoustic signal increases in frequency
as the distance between the vehicle and the
obstacle decreases.
The acoustic signal becomes continuous
when the distance between the vehicle and
the obstacle is less than 11 inches (30 cm),
and stops if the distance increases.
The acoustic signal is constant if the
distance between the vehicle and the
obstacle is unchanged.

NOTE:

If the sensors detect several front and rear
obstacles, the closest obstacle is considered.
An intermittent signal will sound if the obsta -
cles are at the same distance (front and rear).
When the system emits an acoustic signal, the
volume of the radio system, if activated, is
automatically lowered.
An acoustic signal will not sound if the vehicle
is in PARK.
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 On/Off Switch
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 approx
-
imately five seconds. The light will then stay on
constantly.

NOTE:

When the ignition is placed in the ON/RUN
position, the ParkSense system keeps the last
state when the engine was stopped (activated
or deactivated) 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 73.
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.

aid. The Rear Back Up Camera is unable
to view every obstacle or object in your
drive path.
To avoid vehicle damage, the vehicle must
be driven slowly when using the Rear Back
Up Camera to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/her
shoulder when using the Rear Back Up
Camera.
CAUTION!
Never introduce leaded fuel to the tank,
even in small amounts in an emergency, as
this would damage the catalytic converter
beyond repair.

the bottom of the label is your VIN.

WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is
open or the tank is being filled.
Never add fuel when the engine is
running. This is in violation of most state
and federal fire regulations and may
cause the MIL to turn on.

A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place gas
containers on the ground while filling.

TRAILER TOWING
Trailer towing is not recommended for this
vehicle.
SUGGESTIONS FOR DRIVING
Saving Fuel
Below are some suggestions which may help
you save fuel and lower the amount of harmful
emissions released into the atmosphere.
Vehicle Maintenance
Checks and operations should be carried out
in accordance with the Maintenance Plan

Ú
page 204.
Tires
Check the tire pressures at least once every
four weeks: if the pressure is too low,
consumption levels increase as resistance to
rolling is higher.
Unnecessary Loads
Do not travel with an overloaded trunk. The
weight of the vehicle and its arrangement
greatly affect fuel consumption and stability.
Electric Devices
Use electrical systems only for the amount of
time needed. The rear window defroster, addi -
tional headlights, windshield wipers and
heater blower fan require a considerable
amount of energy; increasing the current
uptake increases fuel consumption (by up to
+25% when city driving). Climate Control System
Using the climate control system will increase
consumption: use standard ventilation when
the temperature outside permits.
Devices for Aerodynamic Control
The use of non-certified devices for aerody
-
namic control may adversely affect air drag
and consumption levels.
Driving Style
Starting
Do not warm up the engine at low or high revs
when the vehicle is stationary; this causes the
engine to warm up more slowly, thereby
increasing fuel consumption and emissions. It
is therefore advisable to drive off immediately,
slowly, avoiding high speeds: by doing this the
engine will warm up more quickly.
Unnecessary Actions
Avoid revving up when starting at traffic lights
or before stopping the engine. This action is
unnecessary and causes increased fuel
consumption and pollution.
Gear Selection
Use a high gear when traffic and road condi -
tions allow it. Using a low gear for faster accel -
eration will increase fuel consumption.
Improper use of a high gear increases
consumption, emissions and engine wear. Max. Speed
Fuel consumption considerably increases as
speed increases. Maintain a constant speed,
avoiding unnecessary braking and accelera
-
tion, which cost in terms of both fuel consump -
tion and emissions.
Acceleration

Accelerating violently severely affects consump -
tion and emissions: acceleration should be
gradual and should not exceed the maximum
torque.

Conditions Of Use
Cold Starting
Short trips and frequent cold starts will not
allow the engine to reach optimum operating
temperature. This results in a significant
increase in consumption levels (from +15 to
+30% in city driving) and emissions.
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.
21_GA_OM_EN_USC_t.book Page 138

Transporting Passengers
Transporting Animals
The intervention of the airbags may be
dangerous for an animal on the front seat. It is
therefore advised to arrange animals on the
rear seat inside dedicated cages restrained by
the vehicle’s seat belts.
Keep in mind that, in the event of a sudden
braking or an accident, an inadequately
restrained animal may be projected within the
passenger compartment, risking injury to the
animal itself and the other occupants of the
vehicle.
Exhaust Gas
Exhaust emissions are very dangerous, and
may be lethal. They contain carbon monoxide,
a colorless, odorless gas which can cause
fainting and poisoning if inhaled.
To avoid inhaling carbon monoxide, take the
following measures:
Do not keep the engine running in closed
spaces.
If, for some reason (e.g. transporting bulky
loads), it is necessary to drive with the trunk
open, close all the windows and run the
climate control fan at maximum speed. DO
NOT activate air recirculation mode.
Should it be necessary to stay in the
stationary vehicle with engine running,
adjust the ventilation/heating system and
operate the fan in such a way that outside
air will enter the passenger compartment.
Activate the maximum fan speed.
Maintenance of the exhaust system provides
the best protection against leaks of carbon
monoxide into the passenger compartment.
Should an unusual noise from the exhaust
system or the presence of exhaust gas in the
passenger compartment be identified, or if the
underbody or rear section of the vehicle is
damaged, have the entire exhaust system and
bodywork areas checked to identify any components which are broken, damaged,
worn or have moved from their correct fitting
position. If any of these things occur, contact
an authorized dealer.
Open welding or loose connections may permit
exhaust gas to enter the passenger compart
-
ment.
Check the exhaust system each time the
vehicle is raised for lubrication or oil change
operations. Replace the components if neces -
sary, contact an authorized dealer.
Performance — Quadrifoglio
This vehicle is equipped with an engine
capable of delivering exceptionally fast accel -
eration and speed:
Peak power: 505 HP at 6500 RPM.
Peak torque: 443 ft-lbs at 2500–5000
RPM.
Top speed: 191 mph (307 km/h).
Acceleration from 0 to 60 mph (0 to
100 km/h): 3.8 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.
WARNING!
It is extremely dangerous to leave children
in a parked vehicle when the temperature
outside is very high. The heat inside the
passenger compartment may have
serious, or even fatal, consequences.
Never travel in the trunk of the vehicle. In
the event of an accident, anyone inside
the trunk would be at greater risk of
serious or even fatal injury.
Ensure that all the occupants of the
vehicle wear their seat belts correctly and
that any children are positioned correctly
on the dedicated child restraint systems.

STARTING AND OPERATING

140

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 all liquid levels in the engine
compartment.
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
NAO type pads (Non-Asbestos Organic). 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). Preheating The Carbon Ceramic Material
Brake Discs (If Equipped)
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 panel
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.
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 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.
21_GA_OM_EN_USC_t.book Page 140

SAFETY

142

Active Torque Vectoring (ATV) — 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.
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 "under-
steer" condition. Understeer occurs when the
vehicle is turning less than appropriate for the
steering wheel position.
Dynamic Steering Torque (DST)
DST uses the integration of the Electronic
Stability Control (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 contribu-
tion 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 depen
-
dent on the driver’s sensitivity and overall reac -
tion 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.

Drive Train Control (DTC) System — If
Equipped
Some models of this vehicle are equipped with
an All-Wheel Drive (AWD) system, which offers
an optimal drive for countless driving condi -
tions and road surfaces. The system reduces
the slipping of the tires to a minimum, auto -
matically 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 and environmental
conditions are such that they wouldn't cause
the tires to slip. When the road and environ -
mental conditions require better traction, the
vehicle automatically goes to AWD mode.

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)
The ESC system improves the directional
control and stability of the vehicle in various
driving conditions.
The ESC system corrects the vehicle’s under -
steer 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.
Oversteer occurs when the vehicle 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.
The ESC system uses sensors installed on the
vehicle to determine the path that the driver
intends to follow and compares it with the
vehicle’s effective path. When the real path
deviates from the desired path, the ESC
system intervenes to counteract the above
conditions.
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.
21_GA_OM_EN_USC_t.book Page 142

143

Hill Start Assist (HSA)
This is an integral part of the ESC system and
facilitates starting on slopes, activating auto-
matically in the following cases:
Uphill: vehicle stationary on a road with a
gradient higher than 5%, engine running,
brake pressed and transmission in
NEUTRAL (N) or gear other than REVERSE
(R) engaged.
Downhill: vehicle stationary on a road with a
gradient higher than 5%, engine running,
brake pressed and REVERSE gear engaged.
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)
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.
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 inappro -
priate 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 prop -
erly 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 perfor-
mance. Improperly inflated and unevenly
worn tires may also degrade ESC perfor -
mance. 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!
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.
