2010 JEEP GRAND CHEROKEE warning

This safety belt system has a retractor assem-
bly that is designed to release webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the occu-
pant’s chest.
WARNING!
•The belt and retractor assembly must be
replaced if the seat belt assembly Auto-
matic Locking Retractor (ALR) feature or
any other seat belt function is not working
properly when checked according to the
procedures in the Service Manual.
• Failure to replace the belt and retractor
assembly could increase the risk of injury in
accidents.
Automatic Locking Retractors (ALR)
Mode — If Equipped
In this mode, the shoulder belt is automatically
pre-locked. The belt will still retract to remove
any slack in the shoulder belt. The Automatic
Locking Mode is available on all passenger-
seating positions with a combination lap/
shoulder belt. When To Use The Automatic Locking Mode
Use the Automatic Locking Mode anytime a
child safety seat is installed in a seating posi-
tion that has a belt with this feature. Children
12 years old and under should always be
properly restrained in the rear seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts,
you will hear a clicking sound. This indicates
the safety belt is now in the Automatic Locking
Mode.
How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
Seat Belts In Passenger Seating
Positions
The seat belts in the passenger seating posi-
tions are equipped with Automatic Locking
Retractors (ALR) which are used to secure a
child restraint system. For additional informa-
tion refer to “Installing Child Restraints Using
the Vehicle Seat Belt” under the “Child Re-
straints” section. The chart below defines the
type of feature for each seating position.

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 an accident.
Supplemental Restraint System
(SRS) — Airbags
This vehicle has Advanced Front Airbags for
both the driver and front passenger as a
supplement to the seat belt restraint systems.
The driver’s Advanced Front Airbag is mounted
in the center of the steering wheel. The passen-
ger’s Advanced Front Airbag is mounted in the
instrument panel, above the glove compart-
ment. The words SRS AIRBAG are embossed
on the airbag covers. In addition, the vehicle is
equipped with a driver side knee airbag
mounted in the instrument panel below the
steering column.The Advanced Front Airbags have a multistage
inflator design. This allows the airbag to have
different rates of inflation based on the severity
and type of collision.
This vehicle is equipped with Supplemental
Side Airbag Inflatable Curtains (SABIC) to pro-
tect the driver, front, and rear passengers sit-
ting next to a window. The SABIC airbags, are
located above the side windows and their
covers are also labeled: SRS AIRBAG.This vehicle is equipped with Supplemental
Seat-Mounted Side Airbags (SAB) to provide
enhanced protection for an occupant during a
side impact. The Supplemental Seat-Mounted
Side Airbags are located in the outboard side
of the front seats.
NOTE:
•
Airbag covers may not be obvious in the
interior trim; but they will open during
airbag deployment.
• After any accident, the vehicle should be
taken to an authorized dealer immedi-
ately.

Advanced Front Airbag FeaturesThe Advanced Front Airbag system has multi-
stage driver and front passenger airbags. This
system provides output appropriate to the se-
verity 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 airbag deploy- ment. 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 airbag on the instrument panel, be-
cause any such objects could cause harm if
the vehicle is in a collision severe enough
to cause the airbag to inflate.
• Do not put anything on or around the airbag
covers or attempt to open them manually.
You may damage the airbags and you
could be injured because the airbags may
no longer be functional. The protective cov-
ers for the airbag cushions are designed to
open only when the airbags 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, citi-
zen band radios, etc. Supplemental Seat-Mounted Side Airbags
(SAB)
Supplemental Seat-Mounted Side Airbags pro-
vide enhanced protection to help protect an
occupant during a side impact. The Supple-
mental Seat-Mounted Side Airbag is marked
with an airbag label sewn into the outboard
side of the front seats.
When the airbag deploys, it opens the seam
between the front and side of the seat’s trim
cover. Each airbag deploys independently, that
is a left side impact deploys the left airbag only
and a right-side impact deploys only the right
airbag.

Supplemental Side Airbag Inflatable
Curtain (SABIC)
SABIC airbags may offer side-impact and ve-
hicle rollover protection to front and rear seat
outboard occupants in addition to that pro-
vided by the body structure. Each airbag fea-
tures inflated chambers placed adjacent to the
head of each outboard occupant that reduce
the potential for side-impact head injuries. The
curtains deploy downward, covering both win-
dows on the impact side.NOTE:
•
Should a vehicle rollover occur, the pre-
tensioners and/or SAB and SABIC air-
bags on both sides of the vehicle may
deploy.
• Airbag covers may not be obvious in the
interior trim; but they will open during
airbag deployment.
• Being too close to the SAB and SABIC
airbags during deployment could cause
you to be severely injured or killed.
The system includes side impact sensors ad-
jacent to both front and rear seat occupants
that are calibrated to deploy the SABIC airbags
during impacts that require airbag occupant
protection.WARNING!
• If your vehicle is equipped with left and right
Supplemental Side Airbag Inflatable Cur-
tain (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 remain free from any ob-
structions.
• Do not use accessory seat covers or place
objects between you and the side airbags;
the performance could be adversely af-
fected and/or objects could be pushed into
you, causing serious injury.
Supplemental Driver Side Knee Airbag
The supplemental driver side knee airbag pro-
vides enhanced protection and works together
with the advanced driver side frontal airbag
during a frontal impact.
Knee Impact Bolster
The Knee Impact Bolster helps protect the
knees of the passenger side front passenger
by positioning the passenger for the best inter-
action with the Advanced Front Airbags.

Along with seat belts and pretensioners, Ad-
vanced Front Airbags work with the driver side
knee airbag and the passenger side knee
bolster to provide improved protection for the
driver and front passenger. Side airbags also
work with seat belts to improve occupant pro-
tection.
Here are some simple steps you can take to
minimize the risk of harm from a deploying
airbag:
Children 12 years old and under should always
ride buckled up in a rear seat.
WARNING!
Infants in rear-facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Airbag. An airbag
deployment can cause severe injury or death
to infants in that position.
Children that are not big enough to wear the
vehicle seat belt properly (see Section on Child
Restraints) should be secured in the rear seat
in child restraints or belt-positioning booster
seats. Older children who do not use child restraints or belt-positioning booster seats
should ride properly buckled up in the rear
seat. Never allow children to slide the shoulder
belt behind them or under their arm.
You should read the instructions provided with
your child restraint to make sure that you are
using it properly.
All occupants should always wear their lap and
shoulder belts properly.
The driver and front passenger seats should be
moved back as far as practical to allow the
Advanced Front Airbags room to inflate.
Do not lean against the door or window. If your
vehicle has side airbags, and deployment oc-
curs, the side airbags will inflate forcefully into
the space between you and the door.
If the airbag system in this vehicle needs to be
modified to accommodate a disabled person,
contact the Customer Center. Phone numbers
are provided under
If You Need Assistance .
WARNING!
• Relying on the airbags alone could lead to
more severe injuries in a collision. The
airbags work with your seat belt to restrain
you properly. In some collisions, the air-
bags won’t deploy at all. Always wear your
seat belts even though you have airbags.
• Being too close to the steering wheel or
instrument panel during Advanced Front
Airbag deployment could cause serious
injury, including death. Airbags need room
to inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
• The Supplemental Side Airbag Inflatable
Curtain (SABIC) and Supplemental Seat-
Mounted Side Airbag (SAB) also need
room to inflate. Do not lean against the
door or window. Sit upright in the center of
the seat.

WARNING!(Continued)
• Being too close to the Supplemental Side
Airbag Inflatable Curtain (SABIC) and/or
Seat-Mounted Side Airbag (SAB) during
deployment could cause you to be severely
injured or killed.
Airbag Deployment Sensors and
Controls
Occupant Restraint Controller (ORC)
The ORC is part of a regulated safety system
required for this vehicle.
The ORC determines if deployment of the front
and/or side airbags in a frontal or side collision
is required. Based on the impact sensors sig-
nals, a central electronic ORC deploys the
Advanced Front Airbags, Supplemental Driver
Side Knee Airbag, Supplemental Side Airbag
Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Airbags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact. Advanced Front Airbags and knee airbag are
designed to provide additional protection by
supplementing the seat belts in certain frontal
collisions depending on the severity and type
of collision. Advanced Front Airbags are not
expected to reduce the risk of injury in rear, or
side collisions.
The Advanced Front Airbags and knee airbag
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, Advanced Front Airbags
may deploy in crashes with little vehicle front-
end damage but that produce a severe initial
deceleration.
The side airbags will not deploy in all side
collisions. Side airbag deployment will depend
on the severity and type of collision.
Because airbag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an airbag should have de-
ployed.Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating airbag.
The ORC monitors the readiness of the elec-
tronic parts of the airbag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, the
airbag system is not on and the airbags will not
inflate.
The ORC contains a backup power supply
system that may deploy the airbags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, the ORC turns on the Airbag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the
self-check, the Airbag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Airbag Warning
Light, either momentarily or continuously. A
41

single chime will sound if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Airbag Warning Light if a
malfunction is noted that could affect the airbag
system. The diagnostics also record the nature
of the malfunction.
WARNING!
Ignoring the Airbag Warning Light in your
instrument panel could mean you won’t have
the airbags to protect you in a collision. If the
light does not come on, stays on after you
start the vehicle, or if it comes on as you drive,
have an authorized dealer service the airbag
system immediately.
Driver and Passenger Advanced Front
Airbag Inflator Units
The Driver and Passenger Advanced Front
Airbag Inflator Units are located in the center of
the steering wheel and the right side of the
instrument panel. When the ORC detects a
collision requiring the Advanced Front Airbags,
it signals the inflator units. A large quantity of non-toxic gas is generated to inflate the Ad-
vanced Front Airbags. Different airbag inflation
rates are possible, based on the collision type
and severity. The steering wheel hub trim cover
and the upper right side of the instrument panel
separate and fold out of the way as the airbags
inflate to their full size. The airbags fully inflate
in about 50 to 70 milliseconds. This is about half
of the time it takes to blink your eyes. The
airbags then quickly deflate while helping to
restrain the driver and front passenger.
The Advanced Front Airbag gas is vented
through the vent holes in the sides of the
airbag. In this way, the airbags do not interfere
with your control of the vehicle.
Supplemental Driver Side Knee Airbag
Inflator Unit
The driver side knee airbag unit is located in
the instrument panel trim beneath the steering
column. When the ORC detects a collision
requiring the airbag, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the knee airbag. The trim cover sepa-
rates and folds out of the way allowing the
airbag to inflate to the full size. The airbag fully
inflates in about 15 to 20 milliseconds.Supplemental Seat-Mounted Side Airbag
(SAB) Inflator Units
The Supplemental Seat-Mounted Side Airbags
are designed to activate only in certain side
collisions.
The ORC determines if a side collision requires
the side airbags to inflate based on the severity
and type of collision.
Based on the severity and type of collision, the
side airbag inflator on the crash side of the
vehicle may be triggered, releasing a quantity
of non-toxic gas. The inflating side airbag exits
through the seat seam into the space between
the occupant and the door. The side airbags
fully inflate in about 10 milliseconds. The side
airbag moves at a very high speed and with
such a high force, that it could injure you if you
are not seated properly, or if items are posi-
tioned in the area where the side airbag in-
flates. This especially applies to children.
Supplemental Side Airbag Inflatable
Curtain (SABIC) Inflator Units
During collisions where the impact is confined
to a particular area of the side of the vehicle,
the ORC may deploy the SABIC airbags, de-
42

•As the airbags deflate, you may see some
smoke-like particles. The particles are a nor-
mal by-product of the process that gener-
ates the non-toxic gas used for airbag infla-
tion. 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 airbags have
deployed. If you are involved in another colli-
sion, the airbags will not be in place to protect
you.
WARNING!
Deployed airbags and seat belt pretensioners
cannot protect you in another collision. Have
the airbags, seat belt pretensioners, and the
front seat belt retractor assemblies replaced
by an authorized dealer as soon as possible.
Also, have the Occupant Restraint Controller
(ORC) system serviced as well. Maintaining Your Airbag System
WARNING!
•
Modifications to any part of the airbag
system could cause it to fail when you need
it. You could be injured if the airbag system
is not there to protect you. Do not modify
the components or wiring, including adding
any kind of badges or stickers to the steer-
ing 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 airbag system yourself. Be sure to tell
anyone who works on your vehicle that it
has an airbag system.
(Continued)
WARNING!(Continued)
• Do not attempt to modify any part of your
advanced airbag system. The airbag may
inflate accidentally or may not function
properly if modifications are made. Take
your vehicle to an authorized dealer for any
advanced airbag 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 at-
tachment bolts), take the vehicle to your
authorized dealer. Only manufacturer ap-
proved seat accessories may be used. If it
is necessary to modify the airbag system
for persons with disabilities, contact your
authorized dealer.
