2012 JEEP GRAND CHEROKEE warning

Seat Belt Lock Out
The center rear seat belt system has a lock out feature that
will not allow you to extract the center webbing unless
the rear seat upper latch is engaged.
Seat Belts And Pregnant Women
We recommend that pregnant women use the seat belts
throughout their pregnancy. Keeping the mother safe is
the best way to keep the baby safe.
Pregnant women should wear the lap part of the belt
across the thighs and as snug across the hips as possible.
Keep the belt low so that it does not come across the
abdomen. That way the strong bones of the hips will take
the force if there is a collision.
Seat Belt Extender
If a seat belt is too short, even when fully extended and
when the adjustable upper shoulder belt anchorage (if
equipped) is in its lowest position, your authorized
dealer can provide you with a seat belt extender. Thisextender should be used only if the existing belt is not
long enough. When it is not required, remove the ex-
tender and store it.
WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap 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.

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.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.

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 Seat-Mounted Side
Air Bags and SABIC air bags during impacts that require
side air bag occupant protection.
WARNING!
•Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Curtain
(SABIC), do not stack luggage or other cargo up
high enough to block the location of the SABIC.
The area where the SABIC is located should re-
main free from any obstructions. (Continued)

WARNING! (Continued)
•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.
•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.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bags.Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved protection for the driver and front passenger. Side
air bags also work with seat belts to improve occupant
protection.
Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
The
ORC is part of a Federally regulated safety system
required for this vehicle.
The ORC determines if deployment of the front and/or
side air bags in a frontal or side collision is required.
Based on the impact sensor’s signals, a central electronic
ORC deploys the Advanced Front Air Bags, SABIC air
bags, SAB air bags, and front seat belt pretensioners, as
required, depending on the severity and type of impact.
72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.
Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation rates
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags,
seat belt pretensioners, and the front seat belt retrac-
tor assemblies replaced by an authorized dealer im-
mediately. Also, have the Occupant Restraint Con-
troller (ORC) system serviced as well.
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 structure,
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.(Continued)

manufacturer approved seat accessories may be
used. If it is necessary to modify the air bag system
for persons with disabilities, contact your autho-
rized dealer.
Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. 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.
