2022 FIAT 500X sensor

184SAFETY
By changing the option to "Near", the system will
warn the driver of a possible accident with the
vehicle ahead of it when the latter is a reduced
distance. This setting offers a reaction time to the
driver lower than the settings "Medium" and "Far",
in the case of a potential accident, which will
provide a more dynamic driving experience.
The setting of the sensitivity of the system is
maintained in memory when the engine is
switched off.
Full Brake Control System Limited Warning
If the instrument cluster display reads “Brake
Control Limited Functionality” or “Brake Control
Limited Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
Full Brake Control system functionality. Although
the vehicle is still drivable under normal
conditions, the active braking may not be fully
available. Once the condition that limited the
system performance is no longer present, the
system will return to its full performance state. If
the problem persists, see an authorized dealer.
Service Full Brake Control System Warning
If the system turns off, and the instrument cluster
display displays “Service Brake Control”.
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer. “Brake Control Front Radar Sensor Temporarily
Blocked” Warning
The “Brake Control Front Radar Sensor
Temporarily Blocked” warning will display when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The system may also
become temporarily blinded due to obstructions,
such as mud, dirt or ice. In these cases, the
instrument cluster display will display “Brake
Control Front Radar Sensor Temporarily Blocked”
and the system will deactivate.
The “Brake Control Front Radar Sensor
Temporarily Blocked” message can sometimes be
displayed while driving in highly reflective areas
(i.e. tunnels with reflective tiles, or ice and snow).
The system will recover after the vehicle has left
these areas. Under rare conditions, when the radar
is not tracking any vehicles or objects in its path
this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
behind the lower grille. In absence of visible
obstructions on the fascia/bumper, it could be
necessary to wipe off the radar directly on the
surface, after having the radar cover removed. It’s
recommended that an authorized dealer performs
this operation.
NOTE:
If the “Brake Control Front Radar Sensor Tempo
-
rarily Blocked” message occurs frequently (e.g.
more than once on every trip) without any snow,
rain, mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit Full Brake Control system operation.
Precautions While Driving With Full Brake
Control System
In certain driving conditions, such as:
Driving in the vicinity of a curve
Small vehicles and/or not aligned to the lane
Lane changing of other vehicles
Passing of vehicles in an oncoming intersection
The intervention of the system could be
unexpected or delayed. The driver must therefore
always pay particular attention, while maintaining
control of the car to drive in complete safety.

22_FD_OM_EN_USC_t.book Page 184

SAFETY185
Driving In The Vicinity Of A Curve
Entering or exiting a large curve, the system could
detect the presence of a vehicle that is in front of
the car, but that does not preside in the same lane.
In cases such as this, the system might respond.

Driving In The Vicinity Of A Curve

Small Vehicles And/Or Not Aligned To The Lane
The system is not able to detect the presence of
vehicles that are in front of the car but placed
outside the field of action of the radar sensor and
could therefore not react in the presence of small
vehicles such as bicycles or motorcycles.
Small Vehicles And/Or Not Aligned To The Lane

Lane Changing Of Other Vehicles
Vehicles that suddenly change lanes, while
standing in the traffic lane of their car and inside
the field of action of the radar sensor may cause
the intervention of the system.

Lane Changing Of Other Vehicles
Passing Of Vehicles In An Oncoming Intersection
The system could temporarily react to a vehicle
that crossed the range of the radar sensor, in an
oncoming intersection.

Passing Of Vehicles In An Oncoming Intersection

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold tire pressure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12° F (6.5° C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
6

22_FD_OM_EN_USC_t.book Page 185

186SAFETY
1 mile (1.6 km) after a three hour period. The cold
tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire
sidewall. The tire pressure will also increase as the
vehicle is driven, this is normal and there should be
no adjustment for this increased pressure.
See Ú page 269 on how to properly inflate the
vehicle's tires.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low pressure
warning limit for any reason, including low
temperature effects, or natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above
the recommended cold tire pressure on the
placard. Once the low tire pressure warning (Tire
Pressure Monitoring System Warning Light)
illuminates, you must increase the tire pressure to
the recommended cold tire pressure in order for
the Tire Pressure Monitoring System Warning Light
to turn off. The system will automatically update
and the Tire Pressure Monitoring System Warning
Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be
driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information. For example, your vehicle may have a
recommended cold (parked for more than three
hours) tire pressure of 30 psi (207 kPa). If the
ambient temperature is 68° F (20° C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20° F (-7° C) will decrease
the tire pressure to approximately 23 psi
(159 kPa). This tire pressure is sufficiently low
enough to turn on the Tire Pressure Monitoring
System Warning Light. Driving the vehicle may
cause the tire pressure to rise to approximately
27 psi (186 kPa), but the Tire Pressure Monitoring
System Warning Light will still be on. In this
situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold tire
pressure value Ú
page 297.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warnings have been established for the
tire size equipped on your vehicle. Undesir -
able 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 recom -
mended that you take your vehicle to an
authorized dealership 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 Tire Pres -
sure Monitoring System sensor.

22_FD_OM_EN_USC_t.book Page 186

SAFETY187
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire gauge, even if underinflation has not
reached the level to trigger illumination of the
Tire Pressure Monitoring System Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Base System
This is the TPMS Warning Light located in
the instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module.
Four Tire Pressure Monitoring System sensors.
Tire Pressure Monitoring System Warning Light.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The Tire Pressure Monitoring System Warning Light
will illuminate in the instrument cluster, an
acoustic signal will be activated, and the “Check
left or right front/rear tire” text message will
display when one or more of the four active road
tire pressures are low. Should this occur, you
should stop as soon as possible, check the
inflation pressure of each tire on your vehicle, and
inflate each tire to the vehicle’s recommended
cold placard pressure value. The system will
automatically update and the Tire Pressure
Monitoring Warning Light will extinguish once the
updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
CHECK TPMS WARNINGS
The Tire Pressure Monitoring System Warning Light
will flash on and off for 75 seconds and remain on
solid when a system fault is detected, an audible
chime will be activated and the “Service Tire
Pressure Monitoring System” text message will
display. If the ignition is cycled, this sequence will
repeat providing the system fault still exists. The
Tire Pressure Monitoring System Warning Light will
turn off when the fault condition no longer exists. A
system fault can occur with any of the following
scenarios:
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.
Snow or ice around the wheels or wheel hous
-
ings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
NOTE:Your vehicle may be equipped with a compact
spare wheel and tire assembly.
The compact spare tire does not have a Tire
Pressure Monitoring System sensor. Therefore,
the TPMS will not monitor the tire pressure in
the compact spare tire.

SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others. If
you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you in
a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the AVV/START or
MAR/ACC/ON/RUN position. If the ignition switch
is in the STOP/OFF/LOCK position the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
in the MAR/ACC/ON/RUN position. After the
self-check, the Air Bag Warning Light will turn off. If
the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system is designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the MAR/ACC/ON/RUN
position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be disabled. In
this condition the air bags may not be ready to
inflate for your protection. Have an authorized
dealer service the air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have the
air bag system to protect you in a collision. If the
light does not come on as a bulb check when the
ignition is first turned on, stays on after you start
the vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag system
immediately.

Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light will
illuminate on the instrument panel. The
Redundant Air Bag Warning Light will stay on until
the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag
Warning Light has come on and a fault has been
detected. If the Redundant Air Bag Warning Light
comes on intermittently or remains on while driving
have an authorized dealer service the vehicle
immediately Ú page 69.
Front Air Bags
This vehicle has front air bags and lap/shoulder
belts for both the driver and front passenger. The
front air bags are a supplement to the seat belt
restraint systems. The driver front air bag is
mounted in the center of the steering wheel. The
passenger front air bag is mounted in the
instrument panel, above the glove compartment.
The words “SRS AIRBAG” or “AIRBAG” are
embossed on the air bag covers.
Front Air Bag/Knee Impact Bolster Locations

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system
provides output appropriate to the severity and
type of collision as determined by the Occupant
Restraint Controller (ORC), which may receive
information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately
during an impact that requires air bag deployment.
A low energy output is used in less severe
collisions. A higher energy output is used for more
severe collisions.

2 — Driver Knee Impact Bolster/Supplemental
Driver Knee Air Bag
3 — Passenger Knee Impact Bolster
WARNING!
Being too close to the steering wheel or instru
-
ment panel during front air bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfort -
ably extending your arms to reach the steering
wheel or instrument panel.
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.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!

(Continued)
This vehicle may be equipped with a driver and/or
front passenger seat belt buckle switch that
detects whether the driver or front passenger seat
belt is buckled. The seat belt buckle switch may
adjust the inflation rate of the Advanced Front Air
Bags.
This vehicle may be equipped with driver and/or
front passenger seat track position sensors that
may adjust the inflation rate of the Advanced Front
Air Bags based upon seat position.
Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and damage
by themselves are not good indicators of whether
or not an air bag should have deployed. Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the Occupants Restraint Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.
The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate
and fold out of the way as the air bags inflate to
their full size. The front air bags fully inflate in less
time than it takes to blink your eyes. The front air
bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
WARNING!
No objects should be placed over or near the
air bag on the instrument panel or steering
wheel because any such objects could cause
harm if the vehicle is in a collision severe
enough to cause the air bag to inflate.
Do not put anything on or around the air bag
covers or attempt to open them manually. You
may damage the air bags and you could be
injured because the air bags may no longer be
functional. The protective covers for the air
bag cushions are designed to open only when
the air bags are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.
WARNING!
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights, stereos,
citizen band radios, etc.

Supplemental Side Air Bag Inflatable Curtain (SABIC)

SABICs may help reduce the risk of head and other
injuries to front and rear seat outboard occupants
in certain side impacts, in addition to the injury
reduction potential provided by the seat belts and
body structure.
The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers the
window. The SABICs inflate with enough force to
injure occupants if they are not belted and seated
properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag.
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain side impact events. Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid
the ORC in determining the appropriate response
to impact events. The system is calibrated to
deploy the Side Air Bags on the impact side of the
vehicle during impacts that require Side Air Bag
occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact deploys the left Side Air Bags only and a right-side
impact deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of whether
or not Side Air Bags should have deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at certain
angles, or some side collisions that do not impact
the area of the passenger compartment. The Side
Air Bags may deploy during angled or offset frontal
collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less time
than it takes to blink your eyes.
WARNING!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended, do
not install any accessory items in your vehicle
which could alter the roof. Do not add an after
-
market sunroof to your vehicle. Do not add
roof racks that require permanent attach -
ments (bolts or screws) for installation on the
vehicle roof. Do not drill into the roof of the
vehicle for any reason.
WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or area
where the side air bags inflate, even if they are
in an infant or child restraint.6
