2009 JEEP GRAND CHEROKEE airbag

•The ORC also turns on the Airbag Warning
Light for 2.5 to 8 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 start
up.
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.
•TheDriver and Passenger Airbag/Inflator Unitsare
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 nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, based on collision severity and occupant
size. 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.

•TheSide Impact SRS Side Curtain Airbagsare de-
signed to activate only in certain side or rollover
collisions. When the Occupant Restraint Control
(ORC) detects a collision requiring the window bags to
inflate, it signals the inflators on the crash side of the
vehicle, and both sides of the vehicle when rollover is
sensed. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in
about 30 milliseconds (about one-quarter of the time 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 window bag
inflates. This especially applies to children. The win-
dow bag is only about 3 in (8 cm) thick when it is
inflated.•TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
If a Deployment Occurs
The airbag system is designed to deploy when the
Occupant Restraint Control (ORC) detects a moderate-to-
severe frontal collision, to help restrain the driver and
front passenger, and then to immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.
If you do have a collision that 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 nontoxic 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 instruc-
tions for cleaning.
•It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, 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 seat belt retractor assem-
bly, replaced by an authorized dealer as soon as
possible.
Enhanced Accident Response Feature
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. The hazard
lights will flash and the fuel will be cut off to the engine.
In addition, after the vehicle has stopped moving, the
interior lights will illuminate to aid visibility and remain
lit until the ignition switch is turned off.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:The interior lights can only be deactivated if the
key is removed from the ignition switch or the vehicle is
driven.
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 steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper or vehicle body struc-
ture.

WARNING! (Continued)
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
•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.

Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Airbag Warning Light does not come on during the six
to eight seconds after the ignition switch is first turned
on,
•Remains on after the six to eight second interval, or
•Flickers, or comes on and remains on for any period of
time while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check the fuseblock for blown fuses. Refer to “Fuses” in Section 7 of this
manual. See your authorized dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder
prior to the moment of airbag deployment, or near
deployment, and up to one-quarter second of high-speed
deceleration data during and/or after airbag deployment
or near-deployment. EDR data are ONLY recorded if an
airbag deploys, or nearly deploys, and are otherwise
unavailable.
NOTE:
•A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.

Child Restraints
Everyone in your vehicle needs to be buckled up all the
time — babies and children, too. Every state in the United
States, and all Canadian provinces, require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led 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
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•Rearward-facing child seats must NEVER be used
in the front seat of a vehicle with the front passen-
ger airbag unless the airbag is turned off. An
airbag deployment could cause severe injury or
death to infants in this position.
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
•A rearward facing infant restraint should only be
used in a rear seat. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. Chrysler LLC also recommends that you
try a child restraint in the vehicle seats where you will
use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•Except for the second row center seating position, all
passenger seat belts are equipped with cinching latch
plates. The second row center position has an auto-
matic locking retractor. Both types of seat belts are
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly behind
the child seat to secure a child restraint top tether
strap.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your vehicle.Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws, contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown under “Engine Oil”, under “Maintenance Proce-
dures” in section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
