FIAT 500L 2017 2.G Service Manual

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.
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.

WARNING! (Continued)
•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.
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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 39

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 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 right
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!
•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 Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver
Knee Air Bag mounted in the instrument panel below
the steering column. The Supplemental Driver Knee Air
Bag provides enhanced protection during a frontal
impact by working together with the seat belts, preten-
sioners, and front air bags.
Supplemental Side Air Bags
Your vehicle is equipped with two types of side air
bags:
1. Supplemental Seat-Mounted Side Air Bags (SABs):
Located in the outboard side of the front seats. The
SABs are marked with a “SRS AIRBAG” or “AIR-
BAG” label sewn into the outboard side of the
seats.
40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The SABs may help to reduce the risk of occupant injury
during certain side impacts and/or vehicle rollover
events, in addition to the injury reduction potential
provided by the seat belts and body structure.
When the SAB deploys, it opens the seam on the
outboard side of the seatback’s trim cover. The inflating
SAB deploys through the seat seam into the space
between the occupant and the door. The SAB moves at
a very high speed and with such a high force that it
could injure occupants if they are not seated properly,
or if items are positioned in the area where the SABinflates. Children are at an even greater risk of injury
from a deploying air bag.
WARNING!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the perfor-
mance could be adversely affected and/or objects
could be pushed into you, causing serious injury.
2. Supplemental Side Air Bag Inflatable Curtains
(SABICs): Located above the side windows. The
trim covering the SABICs is labeled “SRS AIR-
BAG” or “AIRBAG.”
Front Supplemental Seat-Mounted Side Air Bag Label
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 41

SABICs may help reduce the risk of head or other
injuries to front and rear seat outboard occupants in
certain side impacts and/or vehicle rollover events, in
addition to the injury reduction potential provided by
the seat belts and body structure.
The SABICs deploy downward, covering the side win-
dows. An inflating SABIC pushes the outside edge of
the trim 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 arepositioned in the area where the SABICs inflate. Chil-
dren are at an even greater risk of injury from a
deploying air bag.
WARNING!
•
Do not 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 attachments (bolts
or screws) for installation on the vehicle roof. Do
not drill into the roof of the vehicle for any
reason.
The SABICs and SABs (Side Air Bags) are designed to
activate in certain side impacts and certain rollover
events. The Occupant Restraint Controller (ORC) deter-
mines whether the deployment of the Side Air Bags in
a particular side impact or rollover event is appropriate,
based on the severity and type of collision. Vehicle

damage by itself is not a good indicator of whether or
not Side Air Bags should have deployed.
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!
•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.
• Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from
an inflating Side Air Bag. To get the best protec-
tion from the Side Air Bags, occupants must wear
their seat belts properly and sit upright with their
backs against the seats. Children must be prop-
erly restrained in a child restraint or booster seat
that is appropriate for the size of the child.
(Continued)
WARNING! (Continued)
•Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the
center of the seat.
• Being too close to the Side Air Bags during
deployment could cause you to be severely in-
jured or killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air
Bags work with your seat belt to restrain you
properly. In some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt even
though you have Side Air Bags.
NOTE: Air bag covers may not be obvious in the
interior trim, but they will open during air bag deploy-
ment.
Side Impacts
In side impacts, 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 im-
pacts, the Side Air Bags deploy independently; a left2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 43

side impact deploys the left Side Air Bags only and a
right side impact deploys the right Side Air Bags only.
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.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment
of the Side Air Bags in a particular rollover event is
appropriate, based on the severity and type of collision.
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 rollover events.
The rollover sensing system determines if a rollover
event may be in progress and whether deployment is
appropriate. In the event the vehicle experiences a
rollover or near rollover event, and deployment of the
Side Air Bags is appropriate, the rollover sensing sys-
tem will also deploy the seat belt pretensioners on both
sides of the vehicle.The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through side
windows in certain rollover or side impact events.
The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated
with electrical Air Bag System Components listed below:

44 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If A Deployment Occurs
The front air bags are designed to deflate immediately
after deployment.
NOTE:Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with
the air bag system.
If you do have a collision which deploys the air bags,
any or all of the following may occur:
• The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air
bags deploy and unfold. The abrasions are similar to
friction rope burns or those you might get sliding
along a carpet or gymnasium floor. They are not
caused by contact with chemicals. They are not
permanent and normally heal quickly. However, if
you haven’t healed significantly within a few days,
or if you have any blistering, see your doctor imme-
diately.
• As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate
the skin, eyes, nose, or throat. If you have skin or eye irritation, rinse the area with cool water. For nose or
throat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer ’s
instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision, the
air bags will not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners can-
not protect you in another collision. Have the air
bags, seat belt pretensioners, and the seat belt
retractor assemblies replaced by an authorized
dealer immediately. Also, have the Occupant Re-
straint Controller System serviced as well.
NOTE:
• Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.

Enhanced Accident Response System
In the event of an impact, if the communication net-
work remains intact, and the power remains intact,
depending on the nature of the event, the ORC will
determine whether to have the Enhanced Accident
Response System perform the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power
or until the hazard light button is pressed. The
hazard lights can be deactivated by pressing the
hazard light button.
• Turn on the interior lights, which remain on as long
as the battery has power or for 15 minutes from the
intervention of the Enhanced Accident Response
System.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
After the event occurs, when the system is active, a
message regarding fuel cutoff is displayed. Turn the
ignition switch from ignition AVV/START or MAR/ ACC/ON/RUN to ignition STOP/OFF/LOCK. Care-
fully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine com-
partment and fuel tank before resetting the system and
starting the engine.
Depending on the nature of the event the left and right
turn signal lights, located in the instrument panel, may
both be blinking and will continue to blink. In order to
move your vehicle to the side of the road, you must
follow the system reset procedure.

Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper, vehicle body struc-
ture, or add aftermarket side steps or running
boards.
• It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag
system.
• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or
may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat,
including your trim cover and cushion, needs to

be serviced in any way (including removal or
loosening/tightening of seat attachment bolts),
take the vehicle to your authorized dealer. Only
manufacturer approved seat accessories may be
used. If it is necessary to modify the air bag
system for persons with disabilities, contact your
authorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period
of time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
•How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts
were buckled/fastened;
