2019 FIAT 124 SPIDER sensor

back of the front bumper detects a
certain amount of impact by a collision
with a pedestrian or other obstruction
while the vehicle is being driven at a
speed sufficient to activate the system,
the system is activated and the bonnet
is raised (3 = active bonnet warning
light/4 = electronic control unit).
IMPORTANT Do not touch the actuator
2 fig. 59 directly after the active bonnet
has activated. Otherwise, it could result
in a burn as the actuator is hot directly
after the activation.
Operation and handlingAlways make sure that the bonnet is
closed completely before driving.
Otherwise, the system may not operate
normally.
The system may not operate for
about 8 seconds after the ignition is
switched ON.
Use tires of the same specified size
on all four wheels. If tires with different
sizes are used, the system may not
operate normally.
If something hits the area around the
front bumper, the sensor could be
damaged even if the active bonnet
does not activate. Contact a Fiat
Dealership to have the vehicle
inspected.
Do not remove or repair parts or
wiring for the active bonnet. In addition,
do not test the system’s circuitry using
an electric tester. Otherwise, the active
bonnet may activate mistakenly or not
operate normally. Contact a Fiat
Dealership when repairs or replacement
servicing is required.
Do not replace the front bumper,
bonnet, suspension, aero parts, or
wheels with non-genuine FCA parts.
Otherwise, the system may not operate
normally.
Do not install non-genuine FCA
accessories to the front bumper. In
addition, do not install objects on thebonnet. Otherwise, the system may not
operate normally.
Do not close the bonnet excessively
or apply a load to the actuator.
Otherwise, the actuator could be
damaged and cause the system to not
operate normally.
Do not modify the suspension. If the
vehicle height or the damping force of
the suspensions is changed, the
system may not operate normally.
When equipping parts, contact a Fiat
Dealership. If parts are installed
incorrectly, the active bonnet may not
activate normally due to the inability to
detect an impact.
When disposing of the vehicle,
contact a Fiat Dealership. If the vehicle
is not handled correctly, it could result in
injury.
The active bonnet cannot be reused
if it has been activated. Contact a Fiat
Dealership.
If the active bonnet activates
The active bonnet activates under the
following conditions:
if the front of the vehicle hits a
pedestrian or obstruction while the
vehicle is being driven at a speed
sufficient to activate the system, the
system will activate if a certain amount
of impact is applied in a collision even
though no trace may remain on the
5903060100-L12-888
75

77)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.
78)If the active bonnet has activated,
always contact a Fiat 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
a Fiat 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)
79) 80) 81)
The Tire Pressure Monitoring System
(TPMS) monitors the air pressure of all
four tires. If the air pressure of one or
more tires is too low, the system warns
the driver by indicating the tire pressure
monitoring system warning light
in
the instrument cluster and operating a
beep sound. The system monitors the
tire pressures indirectly using the data
sent from the ABS wheel speed
sensors.
To allow the system to operate
correctly, the system needs to be
initialized with the specified tire pressure
(value on the tire pressure label). Refer
to “Tire Pressure Monitoring System
Initialization” in this paragraph.
The warning light flashes when the
system has a malfunction. Refer to
“Warning lights and messages”
paragraph in “Knowing the instrument
panel” chapter.
IMPORTANT Each tire, including the
spare (where provided), should be
checked monthly when cold and
inflated to the inflation pressure
recommended by the vehiclemanufacturer 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 TPMS 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.
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
77

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 or
alternate 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.
Because this system detects slight
changes in tire conditions, the timing ofthe warning may be faster or slower in
the following cases.
the size, manufacturer, or the type of
tires is different from the specification;
the size, manufacturer, or the type of
a tire is different from the others, or the
level of tire wear is excessively different
between them;
a run-flat tire (where provided),
studless tire, snow tire, or tire chains
are used;
an emergency tire is used (tire
pressure monitoring system warning
light may flash and then continue
illuminating);
a tire is repaired using the emergency
flat tire repair kit;
the tire pressure is excessively higher
than the specified pressure, or the tire
pressure is suddenly lowered for some
reason such as a tire burst during
driving;
the vehicle speed is lower than about
15 km/h (9 mph) (including when the
vehicle is stopped), or the drive period
is shorter than 5 minutes;
the vehicle is driven on an extremely
rough road or a slippery, icy road;
hard steering and rapid
acceleration/deceleration are repeated
such as during aggressive driving on a
winding road;
load on the vehicle is applied to a tire
such as by loading heavy luggage toone side of the vehicle;
system initialization has not been
implemented with the specified tire
pressure.
System error activation
When the TPMS warning light flashes,
there may be a system malfunction.
Contact a Fiat 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;
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;
78
SAFETY

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.

SEAT BELT WARNING
LIGHT
The LED on dashboard trim turns on if
the driver or passenger's seat is
occupied and the seat belt is not
fastened with the ignition switched ON.
If the driver or passenger's seat belt is
unfastened (only when the passenger
seat is occupied) and the vehicle is
driven at a speed faster than about
20 km/h, the
LED flashes. After a
short time, the LED stops flashing, but
remains illuminated.
If a seat belt remains unfastened, the
LED flashes again for a given period of
time. In this case, fasten the seat belt.
If the driver or passenger's seat belt is
unfastened after the LED turns on, and
the vehicle speed exceeds 20 km/h, the
LED flashes again.
SEAT BELT
PRETENSIONER AND
LOAD LIMITING
SYSTEMS
PRETENSIONERS
92) 93) 94) 95)
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.

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.
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

98)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.
99)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.
100)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
This warning label is displayed in
compliance with regulations.101)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.
102)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.103)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.
