light JEEP GRAND CHEROKEE 2010 WK / 3.G User Guide

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 may also be equipped with Supplemental
Side Airbag Inflatable Curtains (SABIC) to protect the
driver, front, and rear passengers sitting next to a win-
dow. If the vehicle is equipped with SABIC airbags, they
are located above the side windows and their covers are
also labeled: SRS AIRBAG.
NOTE:Airbag covers may not be obvious in the interior
trim; but they will open during airbag deployment.Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller (ORC)
•Airbag Warning Light
•Driver Front Airbag
•Front Passenger Airbag
•Front and Side Impact Sensors
•Steering Wheel and Column
•Instrument Panel
•Knee Impact Bolster
•Front Seat Belt Pretensioners — if equipped
•Supplemental Side Airbag Inflatable Curtains (SABIC)
— if equipped

Advanced Front Airbag Features
The Advanced Front Airbag system has multistage driver
and front passenger airbags. 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 impact sensors
at the front of the car.
The first stage inflator is triggered immediately during an
impact that requires airbag deployment. The timing of
the second stage determines whether the output force is
low, medium, or high. If a low output is sufficient to meet
the need, the remaining gas in the inflator is expended.WARNING!
•No objects should be placed over or near the
airbag on the instrument panel, because any such
objects could cause harm if the vehicle is in a crash
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 covers for the airbag cushions are
designed to open only when the airbags are inflat-
ing.
•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.
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Advanced Front Airbags 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 deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an airbag 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 airbag.The ORC monitors the readiness of the electronic parts of
the system whenever the ignition switch is in the START
or ON position. If the key is in the LOCK position, in the
ACC position, or not in the ignition, the airbags are not
on and 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 disconnected prior to deployment.
Also, the ORC turns on the Airbag Warning
Light in the instrument panel for approxi-
mately six to eight seconds for a self-check
when the ignition is first turned on. 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 single chime will sound if the light
comes on again after initial startup.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53

It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted. The diagnostics also record the nature of the
malfunction.
WARNING!
Ignoring the Airbag Warning Light in your instru-
ment 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 the airbag system checked right
away.
Driver and Passenger Airbag Inflator Units
The Driver and Passenger 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 airbags, it signals the inflator units.
A large quantity of non-toxic gas is generated to inflatethe Advanced Front Airbags. Different airbag inflation
rates are possible, based on the collision type and sever-
ity. The steering wheel hub trim cover and the upper
right side of the instrument panel separate and fold out
of the way as the bags inflate to their full size. The bags
fully inflate in about 50 to 70 milliseconds. This is about
half of the time it takes to blink your eyes. The bags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger 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 Side Airbag Inflatable Curtain
(SABIC) Inflator Units — If Equipped
During collisions where the impact is confined to a
particular area of the side of the vehicle, the ORC may
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

deploy the SABIC airbags, depending on 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 window. 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 children. 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 SABIC
airbags may deploy on both sides of the vehicle.Front and Side Impact Sensors
In front and side impacts, impact sensors aid the ORC in
determining appropriate response to impact events. Ad-
ditional sensors in the ORC determine the level of airbag
deployment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, 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 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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

•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 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 something 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 abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium 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.
•As the airbags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for
airbag inflation. 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 in-
structions for cleaning.
Do not drive your vehicle after the airbags have de-
ployed. If you are involved in another collision, the
airbags will not be in place to protect you.

WARNING! (Continued)
•Do not attempt to modify any part of your ad-
vanced airbag system. The airbag may inflate
accidentally or may not function properly if modi-
fications are made. Take your vehicle to an autho-
rized dealer for any advanced airbag system ser-
vice. If your seat, including your trim cover and
cushion, needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accesso-
ries may be used. If it is necessary to modify an
advanced airbag system for persons with disabili-
ties, contact your authorized dealer.
Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
•The Airbag Warning Light does not come on for
approximately six to eight seconds when the ignition
switch is first turned ON.
•The light remains on after the approximate six to
eight-second interval.
•The light comes on and 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. The airbags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
