Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h)
when towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For proper tire inflation procedures
Ú
page 224.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle with
that of the trailer. This could cause inadequate
braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge
actuated brake system, an electronic brake
controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
Towing Requirements — Trailer Lights
And Wiring
Whenever you pull a trailer, regardless of the
trailer size, stoplights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.

NOTE:
Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.

NOTE:

Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical
connect) into water.
Be sure to reconnect once clear from
water area.
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
CAUTION!
WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can
overload your brake system and cause it to
fail. You might not have brakes when you
need them and could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and
the vehicle in front of you. Failure to do so
could result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb
(453 kg) loaded, it should have its own brakes
and they should be of adequate capacity.
Failure to do this could lead to accelerated
brake lining wear, higher brake pedal effort,
and longer stopping distances.

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 conditions
allow it. Using a low gear for faster acceleration
will increase fuel consumption. Improper use of a
high gear increases consumption, emissions and
engine wear.
Maximum Speed
Fuel consumption considerably increases as
speed increases. Maintain a constant speed,
avoiding unnecessary braking and acceleration,
which cost in terms of both fuel consumption and
emissions.
Acceleration
Accelerating violently severely affects
consumption 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 crossings),
turn off the engine.
PERFORMANCE — QUADRIFOGLIO
This vehicle is equipped with an engine capable
of delivering exceptionally fast acceleration and
speed:
Peak power: 505 HP at 6,500 RPM.
Peak torque: 443 ft-lb 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 discovering its
performance.
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 199.
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).

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). The sensors are temporarily deactivated when
the vehicle is stationary or the vehicle is in PARK.
The detection area of the system covers approxi -
mately 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
monitors 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 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 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 circum -
stances, the system may activate 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.

NOTE:

For the system to operate properly, the rear
fascia/bumper area where the radar sensors
are located must stay free from snow, ice and
dirt gathered from the road surface.
Do not cover the rear fascia/bumper area
where the radar sensors are located with any
object (e.g. adhesives, bike rack, etc.).
If you wish to install a rear tow eye after
purchasing the vehicle, you will need to
deactivate the system via the radio system.
To access the function, select the following
items in sequence on the main menu:
a. “Driver Assistance”
b. “Blind Spot Alert”
Rear View
The system detects vehicles coming from the rear
part of your vehicle on both sides and entering
the rear detection area with a difference in speed
of less than 25 mph (40 km/h) in relation to your
vehicle.
Overtaking Vehicles
If another vehicle is overtaken slowly, with a
difference in speed of less than approximately
15 mph (25 km/h) and the vehicle stays in the
blind spot for approximately 1.5 seconds, the
warning light on the door mirror of the
corresponding side illuminates.
If the difference in speed between the two
vehicles is greater than approximately 15 mph
(25 km/h), the warning light does not illuminate.
WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.

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.
The RCP system monitors the rear detection
areas on both sides of the vehicle to detect
objects moving toward the sides of the vehicle,
with a minimum speed between approximately
1 mph (1 km/h) and 2 mph (3 km/h) and objects
moving at a maximum speed of 21 mph
(35 km/h), in areas such as parking lots.
The system activation is signaled to the driver by
an audible warning.

NOTE:

If the sensors are covered by objects or
vehicles, the system may not work as
intended.
For the system to operate correctly, the rear
fascia/bumper area where the radar sensors
are located must stay free from snow, ice and
dirt gathered from the road surface.
Do not cover the rear fascia/bumper area
where the radar sensors are located with any
object (e.g. adhesives, bike rack, etc.).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 259.
ACTIVE BLIND SPOT ASSIST (ABSA)
S
YSTEM — 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 presence
of other vehicles in the detection area by illumi -
nating 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).
WARNING!
Rear Cross Path Detection (RCP) is not a back
up aid system. It is intended to be used to help
a driver detect an oncoming vehicle in a
parking lot situation. Drivers must be careful
when backing up, even when using RCP.
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. Failure to do so can result in serious injury
or death.

the operation of the accelerator, brake or clutch
pedals. Only use a floor mat that is securely
attached using the floor mat fasteners so it
cannot slip out of position and interfere with the
accelerator, brake or clutch pedals or impair safe
operation of your vehicle in other ways.
WARNING!
An improperly attached, damaged, folded, or
stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to
interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle
control. To prevent SERIOUS INJURY or DEATH:
 ALWAYS securely attach your
floor mat using the floor mat
fasteners. DO NOT install your floor
mat upside down or turn your floor
mat over. Lightly pull to confirm mat is
secured using the floor mat fasteners on a
regular basis.
 ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor
mat. NEVER install or stack an
additional floor mat on top of an existing
floor mat.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that cannot
be properly attached and secured to your
vehicle. If a floor mat needs to be replaced,
only use a FCA approved floor mat for the

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the
underside or rear of the vehicle is damaged, have
a competent mechanic inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could
permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!

Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit
in a parked vehicle with the engine running
for an extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period, adjust
the ventilation system to force fresh, outside
air into the vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the off position, remove the
key fob from the vehicle, and lock your
vehicle.
