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 thefour to eight seconds when the ignition switch is first in the
ON/RUN position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on intermittently 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. 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 intermit
-
tently or remains on while driving have an authorized dealer
service the vehicle immediately.
For additional information regarding the Redundant Air Bag
Warning Light refer to “Getting To Know Your Instrument
Panel” section of this manual.
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.
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.

250 SAFETY
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 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.Occupant Classification System (OCS) — Front
Passenger Seat
The OCS is part of a Federally regulated safety system for
this vehicle. It is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s seated
weight, as determined by the OCS.
The Occupant Classification System (OCS) consists of the
following:
• Occupant Restraint Controller (ORC)
• Occupant Classification Module (OCM) and Sensor
located in the front passenger seat
• Air Bag Warning Light
Occupant Classification Module (OCM) And Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is located
beneath the passenger seat cushion foam. Any weight on the
seat will be sensed by the Sensor. The OCM uses input from
the Sensor to determine the front passenger’s most probable
classification. The OCM communicates this information to
the ORC. The ORC may reduce the inflation rate of the
Passenger Advanced Front Air Bag deployment based on
2020_DT_1500_OM_US.book Page 250

SAFETY 251
occupant classification. In order for the OCS to operate as
designed, it is important for the front passenger to be seated
properly and properly wearing the seat belt.
The OCS will NOT prevent deployment of the Passenger
Advanced Front Air Bag. The OCS may reduce the inflation
rate of the Passenger Advanced Front Air Bag if the OCS esti-
mates that:
• The front passenger seat is unoccupied or has very light objects on it; or
• The front passenger seat is occupied by a small passenger, including a child; or
• The front passenger seat is occupied by a rear-facing child restraint; or
• The front passenger is not properly seated or his or her weight is taken off of the seat for a period of time. * It is possible for a child to be classified as an adult, allowing
a full-power Passenger Advanced Front Air Bag deploy
-
ment. Never allow children to ride in the front passenger seat
and never install a child restraint system, including a
rear-facing child restraint, in the front passenger seat.

WARNING!
• 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.
• Children 12 years or younger should always ride buckled up in the rear seat of a vehicle with a rear seat.Front Passenger Seat

256 SAFETY
The Air Bag Warning Light in the instrument panel will
turn on whenever the OCS is unable to classify the front
passenger seat status. A malfunction in the OCS may affect
the operation of the air bag system.
If the Air Bag Warning Light does not come on, or stays
on after you start the vehicle, or it comes on as you drive,
take the vehicle to an authorized dealer for service immedi-
ately.
The passenger seat assembly contains critical OCS compo -
nents that may affect the Passenger Advanced Front Air Bag
inflation. In order for the OCS to properly classify the seated
weight of a front seat passenger, the OCS components must
function as designed. Do not make any modifications to the
front passenger seat components, assembly, or to the seat
cover. If the seat, trim cover, or cushion needs service for any
reason, take the vehicle to an authorized dealer. Only FCA
US LLC approved seat accessories may be used.
The following requirements must be strictly followed:
• Do not modify the front passenger seat assembly or
components in any way.
• Do not use prior or future model year seat covers or cush -
ions not designated by FCA US LLC for the specific model
being repaired. Always use the correct seat cover and
cushion specified for the vehicle.WARNING!
• If a child restraint system, child, small teenager or adult in the front passenger seat is seated improperly, the
occupant may provide an output signal to the OCS that
is different from the occupant’s properly seated weight
input. This may result in serious injury or death in a
collision.
• Always wear your seat belt and sit properly, with the seatback in an upright position, your back against the
seatback, sitting upright, facing forward, in the center
of the seat, with your feet comfortably on or near the
floor.
• Do not carry or hold any objects (e.g., backpacks, boxes, etc.) while seated in the front passenger seat. Holding
an object may provide an output signal to the OCS that
is different than the occupant’s properly seated weight
input, which may result in serious injury or death in a
collision.
• Placing an object on the floor under the front passenger seat may prevent the OCS from working properly,
which may result in serious injury or death in a colli -
sion. Do not place any objects on the floor under the
front passenger seat.
2020_DT_1500_OM_US.book Page 256

SAFETY 257
• Do not replace the seat cover or cushion with an after-
market seat cover or cushion.
• Do not add a secondary seat cover or mat.
• At no time should any Supplemental Restraint System (SRS) component or SRS related component or fastener be
modified or replaced with any part except those which are
approved by FCA US LLC.
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. Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental Seat-Mounted
Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs) are
located in the outboard side of the front seats. The SABs are
marked with “SRS AIRBAG” or “AIRBAG” on a label or on
the seat trim on the outboard side of the seats.
The SABs may help to reduce the risk of occupant injury
during certain side impacts, in addition to the injury reduc
-
tion potential provided by the seat belts and body structure.
WARNING!
• Unapproved modifications or service procedures to the passenger seat assembly, its related components, seat
cover or cushion may inadvertently change the air bag
deployment in case of a frontal collision. This could
result in death or serious injury to the front passenger
if the vehicle is involved in a collision. A modified
vehicle may not comply with required Federal Motor
Vehicle Safety Standards (FMVSS) and/or Canadian
Motor Vehicle Safety Standards (CMVSS).
• If it is necessary to modify the air bag system for persons with disabilities, contact an authorized dealer.
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.

SAFETY 261
The Side Air Bags and seat belt pretensioners will not deploy
in all rollover events. The rollover sensing system deter-
mines if a rollover event may be in progress and whether
deployment is appropriate. In the event the vehicle experi -
ences a rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy the side
air bags and 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.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated with
electrical Air Bag System Components listed below:
• 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
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
• Occupant Classification System
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 gymna -
sium floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
4
2020_DT_1500_OM_US.book Page 261

262 SAFETY
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 parti -
cles. 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. 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 network
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 (If Equipped)
• Cut off battery power to the electric motor (If Equipped)
• Flash hazard lights as long as the battery has power
• 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
WARNING!
Deployed air bags and seat belt pretensioners cannot
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 Restraint Controller System serviced
as well.

vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g. headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be changed
from ignition START or ON/RUN to ignition OFF. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
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 passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
