2014 JEEP CHEROKEE warning

Seat Belt Pretensioning
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of a collision.
These devices may improve the performance of the seat
belt by assuring that the belt is tight about the occupant
early in a collision. Pretensioners work for all size occu-
pants, including those in child restraints.
NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt must still be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC). Like the air bags, the preten-
sioners are single use items. A deployed pretensioner or
a deployed air bag must be replaced immediately.
Enhanced Seat Belt Use Reminder System
(BeltAlert®)
BeltAlert® is a feature intended to remind the driver and
front passenger (if equipped with front passenger
BeltAlert®) to fasten their seat belts. The feature is active
whenever the ignition is on. If the driver or front seat
passenger is unbelted, the Seat Belt Reminder Light will
turn on and remain on until both front seat belts are
fastened.
The BeltAlert® warning sequence begins after the vehicle
speed is over 5 mph (8 km/h), by blinking the Seat Belt
Reminder Light and sounding an intermittent chime.
Once the sequence starts, it will continue for the entire
duration or until the respective seatbelts are fastened.
After the sequence completes, the Seat Belt Reminder
Light remains illuminated until the respective seat belts
are fastened. The driver should instruct all other occu-
pants to fasten their seat belts. If a front seat belt is

WARNING!
Using a seat belt extender when not needed can in-
crease the risk of injury in a collision. Only use when
the seat belt is not long enough when it is worn low
and snug and in the recommended seating positions.
Remove and store the extender when not needed.
Supplemental Restraint System (SRS) — Air Bags
This vehicle has Advanced Front Air Bags for both the
driver and front passenger as a supplement to the seat
belt restraint systems. The driver’s Advanced Front Air
Bag is mounted in the center of the steering wheel. The
passenger’s Advanced Front Air Bag is mounted in the
instrument panel, above the glove compartment. The
words SRS AIRBAG are embossed on the air bag covers.
In addition, the vehicle is equipped with a Supplemental
Driver Side Knee Air Bag mounted in the instrumentpanel below the steering column and a Supplemental
Passenger Side Knee Air Bag mounted in the instrument
panel below the glove compartment.

• Front Seat Belt Pretensioners, Seat Belt Buckle Switch,
and Seat Track Position Sensors
• Occupant Classification System (OCS)Advanced 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.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•No objects should be placed over or near the air bag
on the instrument panel, 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.
• Do not drill, cut or tamper with the knee bolster in
any way.
•
Do not mount any accessories to the knee bolster
such as alarm lights, stereos, citizen band radios, etc.
Supplemental Seat-Mounted Side Air Bags (SAB)
Supplemental Seat-Mounted Side Air Bags (SAB) may
provide enhanced protection to help protect an occupant
during a side impact. The SAB is marked with an air bag
label sewn into the outboard side of the seats.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

NOTE:
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• Being too close to the SAB and SABIC air bags during
deployment could cause you to be severely injured or
killed.
• Should a vehicle rollover occur, the pretensioners
and/or SAB and SABIC air bags on both sides of the
vehicle may deploy.
The system includes side impact sensors that are cali-
brated to deploy the Supplemental SAB and SABIC air
bags during impacts that require side air bag occupant
protection.WARNING!
• Your vehicle is equipped with left and right
SABIC, do not stack luggage or other cargo up high
enough to block the location of the SABIC. The
area where the side curtain air bag is located
should remain free from any obstructions.
• Do not use accessory seat covers or place objects
between you and the SAB; the performance could
be adversely affected and/or objects could be
pushed into you, causing serious injury.
• Your vehicle is equipped with SABIC air bags, do
not have any accessory items installed which will
alter the roof, including adding a sunroof to your
vehicle. Do not add roof racks that require perma-
nent attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof of the
vehicle for any reason.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

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 colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
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 key is in the OFF
position, in the ACC position, or not in the ignition, 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.Also, the ORC turns on the Air Bag Warning
Light in the instrument panel for approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. 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 if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment 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 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.
Occupant Classification System (OCS) — Front
Passenger Seat
The OCS is part of a Federally regulated safety system for
this vehicle.
The Occupant Classification System (OCS) consists of the
following:
•Occupant Restraint Controller (ORC)
• Occupant Classification Module (OCM) located in the
front passenger seat •
OCS Sensor located in the front passenger seat
• Air Bag Warning Light
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 sensors estimate that:
•The front passenger seat is unoccupied or has very
light objects in 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 rearward
facing infant seat; or
• The front passenger is not properly seated or his or her
weight is taken off of the seat for a period of time.2

Bag Classification
Rearward-facing infant seat* Reduced-power
deployment
Child, including a child in a forward-facing child
restraint or booster seat* Full-power deployment
OR reduced-power deployment
Properly seated adult Full-power deployment OR reduced-powerdeployment
Unoccupied seat Reduced-power deployment
* It is possible for a child to be classified as an adult,
allowing a full-power front passenger air bag deploy-
ment. Never allow children to ride in the front passenger
seat and never install a child restraint system, including
a rearward-facing infant seat, in the front passenger seat.WARNING!
• Never place a rear facing infant seat in front of an
air bag. A deploying Passenger Advanced Front
Air Bag can cause death or serious injury to a child
12 years or younger, including a child in a rearward
facing infant seat.
• Children 12 years or younger should always ride
buckled up in a rear seat in an appropriate child
restraint.
The OCM works with the OCS sensor to determine the
front passenger seat occupant’s most probable classifica-
tion. The OCS sensor estimates the weight on the front
passenger seat and where that weight is located. The
OCM communicates the classification status to the ORC.
The ORC uses the classification to determine whether the
passenger Advanced Front Air Bag inflation rate should
be modified.
