2021 Abarth 124 Spider sensor

75)The capability of the DSC system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the safety
of others.
76)If the active bonnet has activated,
always contact an Abarth Dealership. If the
bonnet release handle is pulled after the
active bonnet has activated, the bonnet will
rise even further. If the vehicle is driven with
the bonnet raised it will obstruct visibility
and could result in an accident. In addition,
do not attempt to push the bonnet back
down. Otherwise, it could deform the
bonnet or cause injury because the
activated bonnet cannot be lowered
manually. Before driving the vehicle contact
an Abarth Dealership after the active
bonnet has activated, make sure that the
raised bonnet does not obstruct vision and
drive the vehicle at a low speed.AUXILIARY DRIVING
SYSTEMS
TPMS (Tire Pressure
Monitoring System)
(Where provided)
77) 78) 79)
The Tire Pressure Monitoring System
(TPMS) monitors the pressure for each
tire. If tire pressure is too low in one or
more tires, the system will inform the
driver via the warning light in the
instrument cluster and by the warning
beep sound. Refer to “Warning lights
and messages” paragraph “Knowing
the instrument panel” chapter.
Refer to “Tire inflation pressure warning
beep” in “Warning sound is activated” in
Knowing the instrument panel” chapter.
The tire pressure sensors installed on
each wheel send tire pressure data by
radio signal to the receiver unit in the
vehicle.
NOTE When the ambient temperature is
low due to seasonal changes, tire
temperatures are also lower. When the
tire temperature decreases, the air
pressure decreases as well. The TPMS
warning light may illuminate more
frequently. Visually inspect the tires daily
before driving, and check tire pressures
monthly with a tire pressure gauge.
When checking tire pressures, use of adigital tire pressure gauge is
recommended.
TPMS does not alleviate your need to
check the pressure and condition of all
four tires regularly.
IMPORTANT Each tire, including the
spare (where 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).
IMPORTANT As an added safety
feature, your vehicle has been equipped
with a TMPS system 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.
77

IMPORTANT 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.
IMPORTANT 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 oralternate tires and wheels allow the
TPMS to continue to function properly.
IMPORTANT To avoid false readings,
the system samples for a little while
before indicating a problem. As a result
it will not instantaneously register a
rapid tire deflation or blow out.
System error activation
When the TPMS warning light flashes,
there may be a system malfunction.
Contact an Abarth Dealership.
A system error activation may occur in
the following cases:
when there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors;
when a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire pressure sensor to
the receiver unit;
when using the following devices in
the vehicle that may cause radio
interference with the receiver unit: a
digital device such as a personal
computer or a current converter device
such as a DC-AC converter;
when excess snow or ice adheres to
the vehicle, especially around the
wheels;
when the tire pressure sensor
batteries are exhausted;
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 an Abarth Dealership
change your tire and complete ID signal
code registration.
When having tires changed at an
Abarth Dealership: when an Abarth
Dealership changes your vehicle's tires,
they will complete the tire pressure
sensor ID signal code registration.
78
SAFETY

When changing tires yourself:ifyou
or 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 an Abarth 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 an Abarth 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.
MECHANICAL LIMITED
SLIP DIFFERENTIAL
Your vehicle is equipped with a
mechanical limited slip differential. In
particular this vehicle adopts a
super-LSD which guarantees improved
vehicle traction and handling.
A super-LSD with a low torque bias
ratio (*) has been adopted to improve
performance when starting from a
standstill, driving straight-ahead and
response.
(*)Torque bias ratio: when a wheel
slips due to a low-traction surface, the
LSD provides proportionally more
torque to the opposite wheel. The
torque bias ratio is the ratio of torque
supplied to the right and left wheels in
such cases, and represents the
performance capability of the LSD.
The super-LSD is a torque-sensing type
that provides improved driving stability
due to the following characteristics:
low torque bias ratio provides
improved controllability (torque bias
ratio: 2.0);
creation of initial torque provides
improved starting from a standstill and
acceleration/deceleration response, and
driving straight-ahead (initial torque:
49 Nm);
simplified construction provides
weight reduction.

SEAT BELT
PRETENSIONER AND
LOAD LIMITING
SYSTEMS
PRETENSIONERS
90) 91) 92) 93)
For optimum protection, the driver and
passenger seat belts are equipped with
pretensioner and load limiting systems.
For both these systems to work
properly you must wear the seat belt
properly.
When a collision is detected, the
pretensioners deploy simultaneously
with the air bags. For deployment
details, refer to the “SRS air bag
deployment criteria” paragraph in this
chapter.
The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have fired they must be
replaced.A system malfunction or operation
conditions are indicated by a warning.
Refer to “Warning lights and messages”
and “Warning sound is activated”
paragraph in “Knowing the instrument
panel” chapter.
In addition, the pretensioner system for
the passenger, like the front and side
passenger air bag, is designed to only
deploy when the passenger occupant
classification sensor detects a
passenger sitting on the passenger's
seat. For details, refer to the passenger
occupant classification sensor.
IMPORTANT The pretensioner system
may not operate depending on the type
of the collision. For details, refer to the
“SRS Air Bag deployment criteria”
paragraph.
IMPORTANT Some smoke (non-toxic
gas) will be released when the air bags
and pretensioners deploy. This does
not indicate a fire. This gas normally
has no effect on occupants, however,
those with sensitive skin may
experience slight skin irritation. If
residue from the deployment of the air
bags or the pretensioner system gets
on the skin or in the eyes, wash it off as
soon as possible.
LOAD LIMITER
The load limiting system releases belt
webbing in a controlled manner to
reduce belt force on the occupant's
chest.
While the most severe load on a seat
belt occurs in frontal collisions, the load
limiter has an automatic mechanical
function and can activate in any
accident mode with sufficient occupant
movement.
Even if the pretensioners have not fired,
the load limiting function must be
checked by Abarth Dealership.
WARNING
90)Wear seat belts only as recommended
in this Owner Handbook. Incorrect
positioning of the driver and passenger
seat belts is dangerous. Without proper
positioning, the pretensioner and load
limiting systems cannot provide adequate
protection in an accident and this could
result in serious injury. For more details
about wearing seat belts, refer to
"Fastening the seat belts".
85

91)Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended. Always have an
expert repairer: contact an Abarth
Dealership immediately for seat belt
pretensioners and air bags inspections
after any collision. Like the air bags, the
seat belt pretensioners and load limiters will
only function once and must be replaced
after any collision that caused them to
deploy. If the seat belt pretensioners and
load limiters are not replaced, the risk of
injury in a collision will increase.
92)Do not modify the components or
wiring, or use electronic testing devices on
the pretensioner system. Modifying the
components or wiring of the pretensioner
system, including the use of electronic
testing devices is dangerous. You could
accidentally activate it or make it inoperable
which would prevent it from activating in an
accident. The occupants or repairers could
be seriously injured.
93)Properly dispose of the pretensioner
system. Improper disposal of the
pretensioner system or a vehicle with non
deactivated pretensioners is dangerous.
Unless all safety procedures are followed,
injury could result. Contact an Abarth
Dealership for safely dispose of the
pretensioner system or scrap a
pretensioner system equipped vehicle.CHILD-RESTRAINT
PRECAUTIONS
94) 95) 96) 97) 98) 99) 100) 101) 102) 103) 104)
FCA strongly urges the use of
child-restraint systems for children small
enough to use them.
FCA recommends use of a genuine
child-restraint system or one that
complies with the UNECE 44 (*)
regulation. If you would like to purchase
a FCA genuine child-restraint system,
please contact an Abarth Dealership.
Check your local and state or provincial
laws for specific requirements regarding
the safety of children riding in your
vehicle.
(*) UNECE stands for United Nations
Economic Commission for Europe.
Whatever child-restraint system you
consider, please pick the appropriate
one for the age and size of the child,
obey the law and follow the instructions
that come with the individual
child-restraint system.A child who has outgrown
child-restraint systems should use seat
belts, both lap and shoulder. If the
shoulder belt crosses the neck or face,
move the child closer to the centre of
the vehicle.
A rear-facing child-restraint system
shouldNEVERbe used on the
passenger seat with the air bag system
activated. In the event of an impact the
air bag activation may cause fatal
injuries to the transported child.
To reduce the chance of injuries caused
by deployment of the passenger air
bag, the passenger occupant
classification sensor work as a part of
the supplementary restraint system.
This system deactivates the passenger
front and side air bags and also the
passenger seat belt pretensioner
system when the passenger air bag
deactivation OFF indicator light
illuminates.
86
SAFETY

When an infant or small child sits on the
passenger seat, the system shuts off
the passenger front and side air bags
and seat belt pretensioner system, so
make sure the passenger air bag
deactivation OFF indicator light
illuminates. For more details, refer to
"Passenger occupant classification
sensor" in “Front Air Bags” paragraph.
IMPORTANT A seat belt or
child-restraint system can become very
hot in a closed vehicle during warm
weather. To avoid burning yourself or a
child, check them before you or your
child touches them.
NOTE Your vehicle is equipped with
ISOFIX anchors for attachment of
ISOFIX child-restraint systems. When
using these anchors to secure a
child-restraint system, refer to “Using
ISOFIX anchor” paragraph in this
chapter.
87

96)Always secure a child in a proper
child-restraint system. Holding a child in
your arms while the vehicle is moving is
extremely dangerous. No matter how
strong the person may be, he or she
cannot hold onto a child in a sudden stop
or collision and it could result in serious
injury or death to the child or other
occupants. Even in a moderate accident,
the child may be exposed to air bag forces
that could result in serious injury or death
to the child, or the child may be slammed
into an adult, causing injury to both child
and adult.
97)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.
98)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 AIRBAG in front of it, DEATH or
SERIOUS INJURY to the CHILD can occur.
Vehicles with a passenger air bag have a
warning label attached on the passenger
side sun visor (refer to “Passenger side
front air bag and child-restraint systems”).
This warning label is displayed in
compliance with regulations.99)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 a passenger occupant
classification system, always make sure the
passenger air bag deactivation OFF
indicator light is illuminated, when installing
a rear-facing child-restraint system on the
passenger seat.
100)Before installing child-restraint system
on the passenger seat, move the
passenger seat as far back as possible.
The rearmost position may not be suitable
for the installation of some child-restraint
systems. In a collision, the force of a
deploying air bag could cause serious
injury or death to the child. Make sure the
passenger air bag deactivation OFF
indicator light is illuminated.101)Seating a child in a child-restraint
system on the passenger seat is
dangerous under certain conditions. Your
vehicle is equipped with passenger
occupant classification sensor. Even with
the passenger occupant classification
sensor, if you must use the passenger seat
to seat a child, using a child-restraint
system on the passenger seat under the
following conditions increases the danger
of the passenger air bag deploying and
could result in serious injury or death to the
child. The passenger air bag deactivation
OFF indicator light does not illuminate
when seating a child in the child-restraint
system / 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 / An additional electrical
device, such as a seat warmer is installed
to the surface of the passenger seat.
