2011 JEEP GRAND CHEROKEE airbag off

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.

• 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

pending on the severity and type of collision. In
these events, the ORC will deploy the SABIC
only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to
inflate the side curtain airbag. The inflating side
curtain airbag pushes the outside edge of the
headliner out of the way and covers the win-
dow. The airbag inflates in about 30 ms (about
one-quarter of the time that it takes to blink your
eyes) with enough force to injure you if you are
not belted and seated properly, or if items are
positioned in the area where the side curtain
airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about
3-1/2 in (9 cm) thick when it is inflated.
Because airbag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an airbag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC airbags may deploy on both
sides of the vehicle.Front and Side Impact Sensors
In front and side impacts, impact sensors can
aid the ORC in determining appropriate re-
sponse to impact events. Additional sensors in
the ORC determine the level of airbag deploy-
ment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag de-
ployment, if the communication network re-
mains 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 follow-
ing functions:
•
Cut off fuel to the engine.
• Flash hazard lights as long as the battery
has power or until the ignition key is turned
off.
• Turn on the interior lights, which remain on as
long as the battery has power or until the
ignition key is removed.
• Unlock the doors automatically. If a Deployment Occurs
The Advanced Front Airbags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side airbags will not deploy in
all collisions. This does not mean some-
thing is wrong with the airbag system.
If you do have a collision which deploys the
airbags, any or all of the following may occur:
•
The nylon airbag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger 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. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.

IL = Suitable for particular ISOFIX child restraint
systems (CRS) given in the attachment list.
These ISOFIX CRS are those of the “specific
vehicle”, “restricted” or “semi-universal” cat-
egories.
X = ISOFIX position not suitable for ISOFIX
child restraint systems in this mass group
and/or this size class.
Children 12 years and under should ride prop-
erly buckled up in a rear seat, if available.
According to crash statistics, children are safer
when properly restrained in the rear seats
rather than in the front.
There are different sizes and types of restraints
for children from newborn size to the child
almost large enough for an adult safety belt.
Always check the child seat Owner’s Manual to
ensure you have the right seat for your child.
Use the restraint that is correct for your child.WARNING!
In an collision, an unrestrained child, even a
tiny baby, can become a projectile inside the
vehicle. The force required to hold even an
infant on your lap can become so great that
you could not hold the child, no matter how
strong you are. The child and others could be
badly injured. Any child riding in your vehicle
should be in a proper restraint for the child’s
size.
Infants and Child Restraints
• Safety experts recommend that children ride
rearward-facing in the vehicle until they are
at least one year old and weigh at least
20 lbs (9 kg). Two types of child restraints
can be used rearward-facing: infant carriers
and convertible child seats.
• The infant carrier is only used rearward-
facing in the vehicle. It is recommended for
children who weigh up to about 20 lbs (9 kg).
Convertible child seats often have a higher
weight limit in the rearward-facing direction
than infant carriers do, so they can be used rearward-facing by children who weigh more
than 20 lbs (9 kg) but are less than one year
old. Both types of child restraints are held in
the vehicle by the lap/shoulder belt or the
ISOFIX child restraint anchorage system
(Refer to “ISOFIX — Child Seat Anchorage
System”)
When using certain Child Restraint Systems
with rigid attachments ISOFIX and foot stands
extending to the vehicle floor, remove the ve-
hicle floor mat prior to installation to ensure a
secure fit. Refer to the Child Restraint Owner’s
Manual for additional information.
WARNING!
• Rearward-facing child seats must never be
used in the front seat of a vehicle with the
front passenger airbag unless the airbag is
turned off. An airbag deployment could
cause severe injury or death to infants in
this position.

INSTRUMENT CLUSTER
DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per
minute (RPM).
2. Airbag Warning Light
This light will turn on for four to eight
seconds as a bulb check when the
ignition switch is first turned to the
ON/RUN position. If the light is ei-
ther not on during starting, stays on,
or turns on while driving, then have
the system inspected at an authorized dealer as
soon as possible. Refer to “Occupant Re-
straints” in “Things To Know Before Starting Your
Vehicle” for further information.
3. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL)
is part of an onboard diagnostic sys-
tem called OBD II that monitors en-
gine and automatic transmission con-
trol systems. The light will illuminate
when the key is in the ON/RUN position before
engine start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the
condition checked promptly.
Certain conditions such as a loose or missing
gas cap, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should
be serviced if the light stays on through several
of your typical driving cycles. In most situa-
tions, the vehicle will drive normally and will not
require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also
could affect fuel economy and drivability. If the
MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Im-
mediate service is required.
WARNING!
A malfunctioning catalytic converter, as refer-
enced above, can reach higher temperatures
than in normal operating conditions. This can
cause a fire if you drive slowly or park over
flammable substances such as dry plants or
wood or cardboard, etc. This could result in
death or serious injury to the driver, occupants
or others.
4. Electronic Stability Control (ESC)
Activation/Malfunction Indicator Light —
If Equipped The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion switch is turned to the ON/
RUN position. It should go out with
the engine running. If the “ESC
Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
