2007 JEEP GRAND CHEROKEE airbag

•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 50–70 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 ORC (with side impact option)
detects a collision requiring the side curtain airbag to
inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the side curtain airbag. The inflating side cur-
tain airbag 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 side
curtain airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about 3
12inches
(9 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) Module 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 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 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.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will illuminate to aid visibility.
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 structure.
•You need proper knee impact protection in a colli-
sion. Do not mount or locate any aftermarket equip-
ment 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:
•Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see the following list) in the event data
recorder prior to the moment of airbag deployment.
Please note that such data are ONLY recorded if an airbag
deploys, and are otherwise unavailable. In conjunctionwith other data gathered during a complete accident
investigation, the electronic data may be used by
DaimlerChrysler Corporation and others to learn more
about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission of the appropriate custodial entity for
the vehicle (usually the vehicle owner or lessee) before
accessing the electronic data stored, unless ordered to
download data by a court with legal jurisdiction (i.e.,
pursuant to a warrant). A copy of the data will be

provided to the custodial entity upon request. General
data that does not identify particular vehicles or crashes
may be released for incorporation in aggregate crash
databases, such as those maintained by the US govern-
ment and various states. Data of a potentially sensitive
nature, such as would identify a particular driver, ve-
hicle, or crash, will be treated confidentially. Confidential
data will not be disclosed by DaimlerChrysler Corpora-
tion to any third party except when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,
provided confidentiality of personal data is thereafter
preserved
2. Used in defense of litigation involving a
DaimlerChrysler Corporation product
3. Requested by police under a legal warrant
4. Otherwise required by lawData Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Ti m eof airbag deployment (in terms of ignition
cycles and vehicle mileage)
•Airbag deployment level (if applicable)
•Seat belt status
•Brake status (service and parking brakes)
•Accelerator status (including vehicle speed)
•Engine control status (including engine speed)
•Cruise control status
•Traction/stability control status

•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 LATCH child restraint anchorage
system (Refer to LATCH — Child Seat Anchorage
System in this section.)
•Rearward-facing child seats mustNEVERbe 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.
WARNING!
•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

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 new 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
detrimental 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 in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.). If there is any question regarding belt or retractor
condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned on. If the bulb is not lit during starting, have it
replaced. If the light stays on or comes on while driving,
have the system checked by an authorized dealer.
Defrosters
Check operation by selecting the defrost mode and place
the blower control on high speed. You should feel the air
directed against the windshield.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for excessive tread wear or uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect for tread cuts or sidewall
cracks. Check wheel nuts for tightness and tires (includ-
ing spare) for proper pressure.
Lights
Have someone observe the operation of all exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
coolant, oil or other fluid leaks. Also, if gasoline fumes
are detected, the cause should be located and corrected
immediately.
