2021 FIAT 124 SPIDER wheel

when using a wheel with no tire
pressure sensor installed;
when using tires with steel wire
reinforcement in the side walls;
when using tire chains.
Tires and wheels
IMPORTANT When inspecting or
adjusting the tire air pressures, do not
apply excessive force to the stem part
of the wheel unit. The stem part could
be damaged.
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure
sensor's unique ID signal code
whenever tires or wheels are changed,
such as changing to and from winter
tires.
IMPORTANT Each tire pressure sensor
has a unique ID signal code. The signal
code must be registered with the TPMS
before it can work. The easiest way to
do it is to have a Fiat Dealership change
your tire and complete ID signal code
registration.
When having tires changed at a Fiat
Dealership: when a Fiat Dealership
changes your vehicle's tires, they will
complete the tire pressure sensor ID
signal code registration.
When changing tires yourself:ifyouor someone else changes tires, you or
someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration:
after tires have been changed, switch
the ignition ON, then back to ACC or
OFF;
wait for about 15 minutes;
after about 15 minutes, drive the
vehicle at a speed of at least 25 km/h
for 10 minutes and the tire pressure
sensor ID signal code will be registered
automatically.
IMPORTANT If the vehicle is driven
within about 15 minutes of changing
tires, the
warning light will flash
because the sensor ID signal code
would not have been registered. If this
happens, park the vehicle for about
15 minutes, after which the sensor ID
signal code will register upon driving the
vehicle for 10 minutes.
Replacing tires and wheels
IMPORTANT When replacing/repairing
the tires or wheels or both, have the
work done by a Fiat Dealership, or the
tire pressure sensors may be damaged.
IMPORTANT The wheels equipped on
your vehicle are specially designed for
installation of the tire pressure sensors.
Do not use non-genuine wheels,otherwise it may not be possible to
install the tire pressure sensors.
Be sure to have the tire pressure
sensors installed whenever tires or
wheels are replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are
possible:
the tire pressure sensor is removed
from the old wheel and installed to the
new one;
the same tire pressure sensor is used
with the same wheel. Only the tire is
replaced;
a new tire pressure sensor is installed
to a new wheel.
IMPORTANT The tire pressure sensor
ID signal code must be registered when
a new tire pressure sensor is
purchased. For purchase of a tire
pressure sensor and registration of the
tire pressure sensor ID signal code,
consult a Fiat Dealership.
IMPORTANT When reinstalling a
previously removed tire pressure sensor
to a wheel, replace the grommet (seal
between valve body/sensor and wheel)
for the tire pressure sensor.

Tire Pressure Monitoring System
initialization
(versions with conventional tires)
In the following cases, system
initialization must be performed so that
the system operates normally:
a tire pressure is adjusted;
tire rotation is performed;
a tire or wheel is replaced;
the battery is replaced or completely
drained;
the tire pressure monitoring system
warning light is illuminated.
Initialization method
Proceed as follows:
park the car in a safe place and firmly
apply the parking brake;
let the tires cool, then adjust the tire
pressure of all four (4) tires to the
specified pressure indicated on the tire
pressure label located on the driver's
door frame (door open);
switch the ignition ON;
while the vehicle is parked, press and
hold the TPMS system set switch
fig. 60 and verify that the tire pressure
monitoring system warning light in the
instrument cluster flashes twice and a
beep sound is heard once.
IMPORTANT If the system initialization
is performed without adjusting the tire
pressure, the system cannot detect the
normal tire pressure and it may not
illuminate the tire pressure monitoring
system warning light even if a tire
pressure is low, or it may illuminate the
light even if the pressures are normal.
IMPORTANT Adjust the tire pressure on
all four tires and initialize the system
when the tire pressure monitoring
system warning light is turned on. If the
warning light turns on for a reason
other than a flat tire, the tire pressure of
all four tires may have decreased
naturally.
IMPORTANT The system initialization
will not be performed if the switch is
pressed while the vehicle is being
driven.HLA (Hill Launch Assist)
FUNCTION
82)
Hill Launch Assist (HLA) is a function
which assists the driver in accelerating
from a stop while on a slope. When the
driver releases the brake pedal and
depresses the accelerator pedal while
on a slope, the function prevents the
vehicle from rolling. The braking force is
maintained automatically after the brake
pedal is released on a steep grade.
For vehicles with a manual
transmission, Hill Launch Assist
operates on a downward slope when
the shift lever is in the reverse (R)
position, and on an upward slope when
the shift lever is in a position other than
the reverse (R) position.
For vehicles with an automatic
transmission, Hill Launch Assist
operates on a downward slope when
the selector lever is in the reverse (R)
position, and on an upward slope when
the selector lever is in a forward gear.
IMPORTANT Hill Launch Assist does
not operate on a gentle slope. In
addition, the gradient of the slope on
which the system will operate changes
depending on the vehicle's load.

SAFETY

IMPORTANT Hill Launch Assist does
not operate if the parking brake is
applied, the vehicle has not stopped
completely, or the clutch pedal is
released.
IMPORTANT While Hill Launch Assist is
operating, the brake pedal may feel stiff
and vibrate, however, this does not
indicate a malfunction.
IMPORTANT Hill Launch Assist does
not operate while the TCS/DSC
indicator light is illuminated. Refer to
“Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.
IMPORTANT Hill Launch Assist (HLA)
does not turn off even if the DSC OFF
switch is pressed to turn off the
TCS/DSC.
IMPORTANT For vehicles with an
automatic transmission although the Hill
Launch Assist does not operate during
idling stop, the vehicle roll prevention
function operates to prevent vehicle roll.
WARNING
79)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tire pressure, including for the spare
wheel, and correct maintenance: the
system is not used to signal a possible fault
to a tire. Tire pressure must be checked
with tires rested and cold. Should it
become necessary for whatever reason to
check pressure with warm tires, do not
reduce pressure even though it is higher
than the prescribed value. Repeat the
check when the tires are cold.
80)Replacing the normal tires with winter
tires and vice versa requires an inspection
of the TPMS, which should be carried out
only by a Fiat Dealership.
81)Changes in outside temperature may
cause tire pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case check the tire
inflation pressure with the tires cold and, if
necessary top up the inflation pressure.82)Do not rely completely on HLA. HLA is
an auxiliary device for accelerating from a
stop on a slope. The system only operates
for about two seconds and therefore,
relying only on the system, when
accelerating from a stop is dangerous
because the vehicle may move (roll)
unexpectedly and cause an accident. The
vehicle could roll depending on the
vehicle's load or if it is towing something. In
addition, for vehicles with a manual
transmission, the vehicle could still roll
depending on how the clutch pedal or the
accelerator pedal is operated. Always
confirm the safety around the vehicle
before starting to drive the vehicle.

SUPPLEMENTARY
RESTRAINT SYSTEM
SRS - AIR BAG
SUPPLEMENTAL
RESTRAINT SYSTEM
(SRS) PRECAUTIONS
118) 119) 120)
The front and side supplementary
restraint systems (SRS) include different
types of air bags.
IMPORTANT Please verify which kinds
of air bags are equipped on your
vehicle by locating the “SRS AIR BAG”
location indicators.
These indicators are visible in the area
where the air bags are installed.
The air bags are installed in the
following locations:
the steering wheel hub (driver air
bag);
the passenger dashboard (passenger
air bag);
the outer sides of the seat backs
(side air bags).The air bag supplementary restraint
systems are designed to provide
supplementary protection in certain
situations so seat belts are always
important in the following ways.
Without seat belt usage, the air bags
cannot provide adequate protection
during an accident. Seat belt usage is
necessary to:
keep the occupant from being
thrown into an inflating air bag;
reduce the possibility of injuries
during an accident that is not designed
for air bag inflation, such as roll-over or
rear impact;
reduce the possibility of injuries in
frontal, near frontal or side collisions
that are not severe enough to activate
the air bags;
reduce the possibility of being thrown
from your vehicle;
reduce the possibility of injuries to
lower body and legs during an accident
because the air bags provide no
protection to these parts of the body;
hold the driver in a position which
allows better control of the vehicle.A child who is too small to use a seat
belt must be properly secured using a
child restraint system.
Carefully consider which child restraint
system is necessary for your child and
follow the installation directions in this
Owner Handbook as well as the child
restraint system manufacturer's
instructions.

139)
Your vehicle is equipped with the
following types of SRS air bags. SRS air
bags are designed to work together
with the seat belts to help to reduce
injuries during an accident. The SRS air
bags are designed to provide further
protection for passengers in addition to
the seat belt functions. Be sure to wear
seat belts properly.
Seat Belt Pretensioners
The seat belt pretensioners are
designed to deploy in moderate or
severe frontal, near frontal collisions. In
addition, during a side collision, the
pretensioner operates on the side in
which the collision occurs. The
pretensioners operate differently
depending on what types of air bags
are equipped. For more details about
seat belt pretensioner operation, refer
to the SRS Air Bag Deployment Criteria.
Driver Air Bag
The driver's air bag is mounted in the
steering wheel fig. 76.When air bag crash sensors detect a
frontal impact of greater than moderate
force, the driver's air bag inflates quickly
helping to reduce injury mainly to the
driver's head or chest caused by
directly hitting the steering wheel. For
more details about air bag deployment,
refer to “SRS Air Bag deployment
criteria” in this chapter.
Passenger Air Bag
(Single stage)
The passenger air bag is mounted in
the passenger dashboard fig. 77.The inflation mechanism for the
passenger air bag is the same as the
driver's air bag. For more details about
air bag deployment, refer to "SRS Air
Bag deployment criteria" in this chapter.
In addition, the passenger air bag is
designed to only deploy when the
passenger occupant classification
sensor detects a passenger sitting on
the passenger's seat. For more details
about air bag deployment, refer to
"SRS Air Bag deployment criteria" in
this chapter.

SAFETY

LIMITATIONS TO SRS AIR
BAG
In severe collisions such as those
described in "SRS Air Bag deployment
criteria" paragraph, the applicable SRS
air bag equipment will deploy.
However, in some accidents, the
equipment may not deploy depending
on the type of collision and its severity.
Limitations to front / near front
collision detection
Front/near front collisions may not be
detected as severe enough to deploy
the SRS air bag equipment:
impacts involving trees or poles A
fig. 80;
frontal offset impact to the vehicle B
fig. 80;
rear-ending or running under a
truck's tail gate fig. 81.Limitations to side collision
detection
Side collisions may not be detected as
severe enough to deploy the SRS air
bag equipment:
side impacts involving trees or poles
A fig. 82;
side impacts with two-wheeled
vehicles B fig. 82;
roll-over fig. 83.

WARNING
118)Seat belts must be worn in air bag
equipped vehicles. Depending only on the
air bags for protection during an accident
is dangerous. Alone, air bags may not
prevent serious injuries. The appropriate air
bags can be expected to inflate only in the
first accident, such as frontal, near frontal
or side collisions that are at least
moderate. Vehicle occupants should
always wear seat belts.
119)Always make sure the passenger air
bag deactivation OFF indicator light is
illuminated when using a child restraint
system. Seating a child in a child-restraint
system that is installed on the passenger
seat with the passenger air bag
deactivation OFF indicator light not
illuminated is extremely dangerous. In an
accident, an air bag could inflate and
cause serious injuries or even death to the
child seated in the child restraint system.
Always make sure the passenger air bag
deactivation OFF indicator light is
illuminated.120)EXTREME HAZARD! Never use a
rear-facing child-restraint system on the
passenger seat with an air bag that could
deploy. NEVER use a rearward facing child
restraint on a seat protected by an ACTIVE
AIR BAG in front of it, DEATH or SERIOUS
INJURY to the CHILD can occur. Even in a
moderate collision, the child-restraint
system can be hit by a deploying air bag
and moved violently backward resulting in
serious injury or death to the child. If your
vehicle is equipped with on passenger
occupant classification system, always
make sure the passenger air bag
deactivation OFF indicator light is
illuminated.
121)Do not sit too close to the driver and
passenger air bags. Sitting too close to the
driver and passenger air bag modules or
placing hands or feet on them is extremely
dangerous. The driver and passenger air
bags inflate with great force and speed.
Serious injuries could occur if someone is
too close. The driver should always hold
onto only the rim of the steering wheel. The
passenger should keep both feet on the
floor. Seat occupants should adjust their
seats as far back as possible and always
sit upright against the seat backs with seat
belts worn properly.122)Do not sit too close to a door or lean
against doors in vehicles with side air bags.
Sitting too close to the side air bag
modules or placing hands on them is
extremely dangerous. A side air bag
inflates with great force and speed directly
out of the outer shoulder of the seat and
expands along the door on the side the car
is hit. Serious injury could occur if someone
is sitting too close to the door or leaning
against a window in the seats.
Furthermore, sleeping up against the door
or hanging out the driver-side window while
driving could block the side air bag and
eliminate the advantages of supplementary
protection. Give the side air bags room to
work by sitting in the center of the seat
while the vehicle is moving with seat belts
worn properly.
123)Sit in the center of the seat and wear
seat belts properly. Sitting too close to the
side air bag modules or placing hands on
them, or sleeping up against the door or
hanging out the windows is extremely
dangerous. The side air bags inflate with
great force and speed directly expanding
along the door on the side the car is hit.
Serious injury could occur if someone is
sitting too close to the door. Give the side
air bags room to work by sitting in the
center of the seat while the vehicle is
moving with seat belts worn properly.
124)Do not attach objects on or around
the area where driver and passenger air
bags deploy. Attaching an object to the
driver and passenger air bag modules or
placing something in front of them is
dangerous. In an accident, an object could
interfere with air bag inflation and injure the
occupants.
110
SAFETY

132)Do not operate a vehicle with
damaged air bag/seat belt pretensioner
system components. Expended or
damaged air bag/seat belt pretensioner
system components must be replaced
after any collision which caused them to
deploy or damage them. Only a trained
expert repairer, we recommend a Fiat
Dealership that can fully evaluate these
systems to see that they will work in any
subsequent accident. Driving with an
expended or damaged air bag or
pretensioner unit will not afford you the
necessary protection in the event of any
subsequent accident which could result in
serious injury or death.
133)Do not remove interior air bag parts.
Removing any components such as the
seats, front instrument panel, the steering
wheel, containing air bag parts or sensors
is dangerous. These parts contain essential
air bag components. The air bag could
accidentally activate and cause serious
injuries. Always have a Fiat Dealership
remove these parts.134)Do not allow an occupant in the
passenger's seat to sit with a posture
which makes it difficult for the passenger
occupant classification sensor to detect
the occupant correctly. Sitting in the
passenger's seat with a posture which
makes it difficult for the passenger
occupant classification sensor to detect
the occupant correctly is dangerous. If the
passenger occupant classification sensor
cannot detect the occupant sitting on the
passenger's seat correctly, the passenger
front and side air bags and pretensioner
system may not operate (non-deploy) or
they may operate (deploy) accidentally. The
passenger will not have the supplementary
protection of the air bags or the accidental
operation (deployment) of the air bags
could result in serious injury or death.
135)Properly dispose of the air bag
system. Improper disposal of an air bag or
a vehicle with live air bags in it can be
extremely dangerous. Unless all safety
procedures are followed, injury could
result. Have an expert repairer, contact a
Fiat Dealership safely dispose of the air bag
system or scrap an air bag equipped
vehicle.
136)When an air bag deploys, a loud
inflation noise can be heard and some
smoke will be released. Neither is likely to
cause injury, however, the texture of the air
bags may cause light skin injuries on body
parts not covered with clothing through
friction.
137)Should you sell your vehicle, we urge
you to tell the new owner of its air bag
systems and that familiarization with all
instructions about them, from the Owner's
Manual, is important.138)Vehicles with a passenger air bag
have a warning label attached (consult
“Passenger side front air bag and child
restraint systems” paragraph). This warning
label is displayed in compliance with
regulations.
139)Under the following conditions, the
passenger occupant classification sensor
cannot detect a passenger sitting on the
passenger's seat correctly and the
deployment/non-deployment of the air
bags cannot be controlled as indicated in
the passenger air bag deactivation
indicator light on/off condition chart. For
example: luggage or other items placed
under the passenger seat or between the
passenger seat and driver seat that push
up the passenger seat bottom / An object,
such as a seat cushion, is put on the
passenger's seat or between the
passenger's back and the seat back / A
seat cover is put on the passenger's seat /
Luggage or other items are placed on the
seat with the child in the child restraint
system / The seat is washed / Liquids are
spilled on the seat / The passenger seat is
moved backward, pushing into luggage or
other items placed behind it / Luggage or
other items are placed between the
passenger seat and driver seat / An electric
device is put on the passenger's seat. The
passenger front and side air bags and seat
belt pretensioner systems will deactivate if
the passenger air bag deactivation OFF
indicator light turns on.
