traction control Alfa Romeo Giulia Quadrifoglio 2017 Owner's Manual

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
and environmental conditions are such
that they wouldn't cause the tires to
slip. When the road and environmental
96
SAFETY

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.
97

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

Caution!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap, MOPAR
Wheel Cleaner or equivalent is
recommended.
Note:
If you intend parking or storing your
vehicle for an extended period after
cleaning the wheels with wheel cleaner,
drive your vehicle for a few minutes
before doing so. Driving the vehicle and
applying the brakes when stopping will
reduce the risk of brake rotor corrosion.Dark Vapor Or Black Satin Chrome
Wheels
Caution!
If your vehicle is equipped with Dark Vapor
or Black Satin Chrome wheels DO NOT
USE wheel cleaners, abrasives or polishing
compounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty. USE
ONLY MILD SOAP AND WATER WITH A
SOFT CLOTH. Used on a regular basis; this
is all that is required to maintain this finish.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and
Winter). Traction levels may vary
between different all season tires. All
season tires can be identified by the
M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling
of your vehicle.
Summer Or Three Season
Tires — If Equipped
Summer tires provide traction in both
wet and dry conditions, and are not
intended to be driven in snow or on ice.
If your vehicle is equipped with Summer
tires, be aware these tires are not
designed for Winter or cold driving
conditions. Install Winter tires on your
vehicle when ambient temperatures are
less than 40°F (5°C) or if roads are
covered with ice or snow. For more
information, contact an authorized
dealer.
Summer tires do not contain the all
season designation or mountain/
snowflake symbol on the tire sidewall.
Use Summer tires only in sets of four;
failure to do so may adversely affect the
safety and handling of your vehicle.
Warning!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
227

See the Tire Sizing Chart example
found in the “Tire Safety Information”
section of this manual for more
information relating to the Load Index
and Speed Symbol of a tire.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling. If you
ever replace a wheel, make sure that
the wheel’s specifications match those
of the original wheels.
It is recommended you contact your
authorized tire dealer or original
equipment dealer with any questions
you may have on tire specifications or
capability. Failure to use equivalent
replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Warning!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose control and have a collision resulting in
serious injury or death. Use only the tire
and wheel sizes with load ratings approved
for your vehicle.
Never use a tire with a smaller load
index or capacity, other than what was
originally equipped on your vehicle. Using a
tire with a smaller load index could result in
tire overloading and failure. You could lose
control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
Caution!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
DEPARTMENT OF
TRANSPORTATION
UNIFORM TIRE
QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each category
is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in addition
to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half times
as well on the government course as a
tire graded 100. The relative
performance of tires depends upon the
actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
232
SERVICING AND MAINTENANCE

under controlled conditions on specified
government test surfaces of asphalt
and concrete. A tire marked C may
have poor traction performance.
Warning!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature Grades
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire
life, and excessive temperature can
lead to sudden tire failure. The grade C
corresponds to a level of performance,
which all passenger vehicle tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B
and A represent higher levels of
performance on the laboratory test
wheel, than the minimum required by
law.
Warning!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
STORING THE
VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Parkthecarinanareathatis
covered and dry, and well-ventilated if
possible. Slightly open the windows.
Check that the electric park brake is
not activated.
Carry out the procedure: “manual
trunk opening device” procedure
described in this paragraph.
Disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage.
If the battery is not disconnected
from the electrical system, check its
state of charge every thirty days.
Clean and protect the painted parts
using protective wax.
Clean and protect the shiny metal
parts using special compounds
available commercially.
Sprinkle talcum powder on the
windshield wiper rubber blades, and lift
them off the glass.
Cover the vehicle with a fabric or
perforated plastic sheet, paying
particular care not to damage the
painted surface by dragging any dust
that may have accumulated on it.
