tire size Alfa Romeo Giulia 2018 Owner's Manual

Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low tire
pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing one
or more tires or wheels on your vehicle, to
ensure that the replacement or alternate
tires and wheels allow the TPMS to
continue to function properly.
Caution!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealership to have your sensor function
checked.

Oversteeroccurs 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.
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.

Operating Example
For example, your vehicle may have a
recommended cold (parked for more than
three hours) placard pressure of 33 psi
(227 kPa). If the ambient temperature is
68°F (20°C), and the measured tire
pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will
decrease the tire pressure to
approximately 24 psi (165 kPa). This tire
pressure is low enough to turn on the
“Tire Pressure Monitoring Warning Light.”
Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the “Tire Pressure
Monitoring Telltale Light” will still be on.
In this situation, the “Tire Pressure
Monitoring Warning Light” will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard
pressure value.
Caution!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPM
sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor damage. Customers are encouraged to use
OEM wheels to assure proper TPM feature
operation.
Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable.
After using an aftermarket tire sealant it is
recommended that you take your vehicle to
your authorized dealer to have your sensor
function checked.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.
Insufficient Tire Pressure Indication
If an insufficient pressure value is
detected on one or more tires, the
warning light in the instrument cluster
will display alongside the dedicated
messages, the system will highlight the
tire or tires with insufficient pressure
graphically, and an acoustic signal will be
emitted.
In this case, stop the vehicle, check the
inflation pressure of each tire, and inflate
the necessary tire or tires to the correct
cold inflation pressure value, shown on
the display or in the dedicated TPMS
menu. TPMS Temporarily Disabled — TPMS
Check Message
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds, and then
remain on solid. The system fault will also
sound a chime. If the ignition is cycled,
this sequence will repeat, provided that
the system fault still exists. The “Tire
Pressure Monitoring Telltale Light” will
turn off when the fault condition no
longer exists. A system fault can occur
due to any of the following:
Jamming due to electronic devices or
driving next to facilities emitting the
same radio frequencies as the TPMS
sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Accumulation of snow or ice around
the wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
After the punctured tire has been
repaired with the original tire sealant
contained in the Tire Repair Kit, the
previous condition must be restored so
that the
warning light is off during
normal driving.

SAFETY

Seat Belt Pretensioner
The front seat belt system is equipped
with pretensioning devices that are
designed to remove slack from the seat
belt in the event of a collision. These
devices may improve the performance of
the seat belt by removing slack from the
seat belt early in a collision. Pretensioners
work for all size occupants, including those
in child restraints.
Note: These devices are not a substitute
for proper seat belt placement by the
occupant. The seat belt still must be worn
snugly and positioned properly.
The pretensioners are triggered by the
Occupant Restraint Controller (ORC). Like
the air bags, the pretensioners are single
use items. A deployed pretensioner or a
deployed air bag must be replaced
immediately.
Energy Management Feature
The front seat belt system is equipped
with an Energy Management feature that
may help further reduce the risk of injury
in the event of a collision. The seat belt
system has a retractor assembly that is
designed to release webbing in a
controlled manner.
Switchable Automatic Locking
Retractors (ALR)
The seat belts in the passenger seating
positions are equipped with a Switchable
Automatic Locking Retractor (ALR) which is used to secure a child restraint system.
For additional information, refer to
“Installing Child Restraints Using The
Vehicle Seat Belt” under the “Child
Restraints” section of this manual.
The figure below illustrates the locking
feature for each seating position.
If the passenger seating position is
equipped with an ALR and is being used
for normal usage, only pull the seat belt
webbing out far enough to comfortably
wrap around the occupant’s mid-section
so as to not activate the ALR. If the ALR
is activated, you will hear a clicking sound
as the seat belt retracts. Allow the
webbing to retract completely in this
case and then carefully pull out only the
amount of webbing necessary to
comfortably wrap around the occupant’s
mid-section. Slide the latch plate into the
buckle until you hear a "click."
In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack
in the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is
installed in a seating position that has a
seat belt with this feature. Children
12 years old and under should always be
properly restrained in the rear seat of a
vehicle with a rear seat.
Warning!
Never place a rear-facing child restraint
in front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Only use a rear-facing child restraint in
the rear seat of a vehicle with a rear seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and pull
downward until the entire seat belt is
extracted.
3. Allow the seat belt to retract. As the
seat belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.

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.
Note: If the filler compartment is
washed with a pressure washer, keep it at
a distance of at least 8 inches (20 cm).
VEHICLE LOADING
Certification Label
As required by National Highway Traffic
Safety Administration regulations, your
vehicle has a certification label affixed to
the driver's side door or pillar.
This label contains the month and year of
manufacture, Gross Vehicle Weight
Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and
Vehicle Identification Number (VIN).
A Month-Day-Hour (MDH) number is
included on this label and indicates the
Month, Day and Hour of manufacture.
The bar code that appears on the bottom
of the label is your VIN.
Gross Vehicle Weight Rating
(GVWR)
The GVWR is the total permissible
weight of your vehicle including driver,
passengers, vehicle, options and cargo.
The label also specifies maximum
capacities of front and rear axle systems
(GAWR). Total load must be limited so
GVWR and front and rear GAWR are not
exceeded.
Payload
The payload of a vehicle is defined as the
allowable load weight a truck can carry,
including the weight of the driver, all
passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible
load on the front and rear axles. The load
must be distributed in the cargo area so
that the GAWR of each axle is not
exceeded.
Each axle GAWR is determined by the
components in the system with the
lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or
suspension components sometimes
specified by purchasers for increased
durability does not necessarily increase
the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification
Label represents the actual tire size on
your vehicle. Replacement tires must be
equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for
the tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for
your vehicle for all loading conditions up
to full GAWR.

Tire Terminology And Definitions
TermDefinition
B-Pillar The
vehicle B-Pillar is the structural member of the body located behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1 mile (1.6 km) after sitting for
a minimum of three hours. Inflation pressure is measured in units of PSI (pounds per
square inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible cold tire inflation
pressure for this tire. The maximum inflation pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer's recommended cold tire inflation pressure as shown on the tire
placard.
Tire Placard A label permanently attached to the vehicle describing the vehicle’s loading capacity,
the original equipment tire sizes and the recommended cold tire inflation pressures.
Tire Loading And Tire Pressure
Note:
The proper cold tire inflation
pressure is listed on the driver’s side

Tire And Loading Information Placard
This placard tells you important
information about the:
1. Number of people that can be carried
in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the
front, rear, and spare tires.
Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle. You
will not exceed the tire's load carrying
capacity if you adhere to the loading
conditions, tire size, and cold tire
inflation pressures specified on the Tire
and Loading Information placard in
“Vehicle Loading” in the “Starting And
Operating” section of this manual.Note:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded. For further
information on GAWRs, vehicle loading,
and trailer towing, refer to “Vehicle
Loading” in the “Starting And Operating”
section of this manual.
To determine the maximum loading
conditions of your vehicle, locate the
statement “The combined weight of
occupants and cargo should never
exceed XXX kg or XXX lbs” on the Tire
and Loading Information placard. The
combined weight of occupants,
cargo/luggage and trailer tongue weight
(if applicable) should never exceed the
weight referenced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight
of the driver and passengers that will
be riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs. (4) The resulting figure equals the
available amount of cargo and
luggage load capacity. For example,
if “XXX” amount equals 1400 lbs. and
there will be five 150 lb passengers
in your vehicle, the amount of
available cargo and luggage load
capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.)
(5) Determine the combined weight
of luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your vehicle.
