2016 FIAT 124 SPIDER pretensioner

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.

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 details on the 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. 74.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. 75.The inflation mechanism for the
passenger air bag is the same as the
driver's air bag, as mentioned above.
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.
Side Air Bags
The side air bags are mounted in the
outer sides of the seat backs fig. 76.
When the air bag crash sensors detect
a side impact of greater than moderate
force, the system inflates the side air

IMPORTANT In a frontal offset collision, the equipped air bags and pretensioners may all deploy depending on the direction,
angle, and rate of impact.

SAFETY
X: the SRS air bag equipment is designed to deploy in a collision.
(*) In a side collision, the seat belt pretensioners and the side air bags deploy (only on the side in which the collision occurs).
(**) The passenger front and side air bags and the seat belt pretensioner are designed to deploy when the passenger occupant
classification sensor detects a passenger sitting on the passenger's seat.

First, please read "Supplemental
Restraint System (SRS) Precautions"
carefully.
Passenger occupant classification
sensor
Your vehicle is equipped with a
passenger occupant classification
sensor as a part of the supplementary
restraint system. This sensor is
equipped in the passenger's seat
cushion. This sensor measures the
electrostatic capacity of the
passenger's seat.
The SAS unit is designed to prevent the
passenger front and side air bags and
seat belt pretensioner system fromdeploying if the passenger air bag
deactivation indicator light turns on.
To reduce the chance of injuries caused
by deployment of the passenger air
bag, the system deactivates the
passenger front and side air bags and
also the seat belt pretensioner system
when the passenger air bag
deactivation indicator light turns on.
This system shuts off the passenger
front and side air bags and seat belt
pretensioner system, so make sure the
passenger air bag deactivation indicator
light turns on.
The air bag/seat belt pretensioner
system warning light flashes and the
passenger air bag deactivation indicator
light illuminates if the sensors have a
possible malfunction. If this happens,
the passenger front and side air bags
and seat belt pretensioner system will
not deploy.
IMPORTANT If a passenger is seated
as shown in the following fig. 82 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.
Passenger air bag deactivation
indicator lights
These indicator lights fig. 83 turn on to
remind you that the passenger front
and side air bags and seat belt
pretensioner will or will not deploy
during a collision.

22) 23)
NoteThe system requires about
10 seconds to alternate between
turning the passenger front and side air
bags and seat belt pretensioner system
on or off.
The passenger air bag deactivation
indicator light may turn on repeatedly if
luggage or other items are put on the
passenger seat, or if the temperature of
the vehicle's interior changes suddenly.
The passenger air bag deactivation
indicator light may turn on for
10 seconds if the electrostatic capacity
on the passenger seat changes.
The air bag/seat belt pretensioner
system warning light might turn on if the
passenger seat receives a severe
impact.
If the passenger air bag deactivation
indicator light does not turn on afterinstalling a child restraint system on the
passenger seat, first, reinstall your child
restraint system according to the
procedure in this Owner Handbook.
Then, if the passenger air bag
deactivation OFF indicator light still
does not turn on, and contact a Fiat
Dealership as soon as possible.
If the passenger air bag deactivation
indicator light turns on when an
occupant is seated directly in the
passenger seat, have the passenger
readjust their posture by sitting with
their feet on the floor, and then
refastening the seat belt. If the
passenger air bag deactivation indicator
light remains turned on, slide the
passenger seat as far back as possible.
Contact a Fiat Dealership as soon as
possible.

(*) The occupant classification sensor may not detect a child seated on the seat, in a child restraint system, or a junior seat
depending on the child's physical size and seated posture.
(**) If a smaller adult sits on the passenger seat, the sensors might detect the person as being a child depending on the
person's physique.
(***) Turns off after a short period of time.
If both of the passenger air bag deactivation indicator lights do not turn on for a specified period of time when the ignition is
switched ON or they do not turn on as indicated in the passenger air bag deactivation indicator light on/off condition chart, do
not allow an occupant to sit in the passenger seat and contact a Fiat Dealership as soon as possible. The system may not work
properly in an accident.
