2016 JEEP CHEROKEE light

weight on the seat will be sensed by the Sensor. The OCM
uses input from the Sensor to determine the front pas-
senger ’s most probable classification. The OCM commu-
nicates this information to the ORC. The ORC may
reduce the inflation rate of the Passenger Advanced Front
Air Bag deployment based on occupant classification. In
order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and prop-
erly 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 estimates that:
•The front passenger seat is unoccupied or has very
light objects on it; or
• The front passenger seat is occupied by a small pas-
senger, 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.

Lighter Weight Passengers (Including Small Adults)
When a lighter weight passenger, including a small adult,
occupies the front passenger seat, the OCS may reduce
the inflation rate of the Passenger Advanced Front Air
Bag. This does not mean that the OCS is working
improperly.Do not decrease OR increase the front passenger ’s
seated weight on the front passenger seat
The front passenger ’s seated weight must be properly
positioned on the front passenger seat. Failure to do so
may result in serious injury or death. The OCS deter-
mines the most probable classification of the occupant
that it detects.
The OCS will detect the front passenger ’s decreased or
increased seated weight, which may result in an adjusted
inflation rate of the Passenger Advanced Front Air Bag in
a collision. This does not mean that the OCS is working
improperly.
Decreasing the front passenger ’s seated weight on the
front passenger seat may result in a reduced-power
deployment of the Passenger Advanced Front Air Bag.
Increasing the front passenger ’s seated weight on the
front passenger seat may result in a full-power deploy-
ment of the Passenger Advanced Front Air Bag.
Seated Properly

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73

WARNING!
•If an occupant in the front passenger seat is seated
improperly, the occupant may provide an output
signal to the OCS that is different from the occu-
pant’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 for-
ward, 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 prop-
erly seated weight input, which may result in
serious injury or death in a collision.
(Continued)
WARNING! (Continued)
•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 collision. Do not place any objects on the
floor under the front passenger seat.
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 Lightdoes 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 immediately.
The passenger seat assembly contains critical OCS com-
ponents that may affect the Passenger Advanced Front
Air Bag inflation. In order for the OCS to properly

Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the Advanced 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 And Front Passenger Knee
Air Bags
This vehicle is equipped with a Supplemental Driver
Knee Air Bag mounted in the instrument panel below the
steering column and a Supplemental Passenger Knee Air Bag mounted in the instrument panel below the glove
compartment. The Supplemental Knee Air Bags provide
enhanced protection during a frontal impact by working
together with the seat belts, pretensioners, and Advanced
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 and rear (in
vehicles equipped with rear seat SABs) seats. The
SABs are marked with a “SRS AIRBAG” or “AIRBAG”
label sewn into the outboard side of the seats.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

Do not drive your vehicle after the air bags have de-
ployed. 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 cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer imme-
diately. Also, have the Occupant Restraint 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 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 Sys-
tem 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.
• Unlock the power door locks.

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.
Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Occupant Re-
straint Controller (ORC) monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch is in the OFF position or in the ACC 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 bags 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 first turned to
the ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function 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 malfunc-
tion is detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 87

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 ignition switch is
first turned to 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 protec-
tion. 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 bags to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first placed in the
on position, and 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.
