of the impact. In addition, theseroof-rail airbags are designed toinflate during a rollover. Roof-railairbags are not designed to inflate infrontal, near-frontal, or rear impacts.All roof-rail airbags will inflate wheneither side of the vehicle is struck orif the sensing system predicts thatthe vehicle is about to roll over onits side.
In any particular crash, no one cansay whether an airbag should haveinflated simply because of thevehicle damage or repair costs.
What Makes an Airbag
Inflate?
In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fills theairbag causing the bag to break outof the cover. The inflator, the airbag,and related hardware are all part ofthe airbag module.
For airbag locations, seeWhere Arethe Airbags?057.
How Does an Airbag
Restrain?
In moderate to severe frontal ornear frontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel. Inmoderate to severe side collisions,even belted occupants can contactthe inside of the vehicle.
Airbags supplement the protectionprovided by safety belts bydistributing the force of the impactmore evenly over theoccupant's body.
Rollover capable roof-rail airbagsare designed to help contain thehead and chest of occupants in theoutboard seating positions in thefirst, second, and third rows,if equipped. The rollover capableroof-rail airbags are designed tohelp reduce the risk of full or partialejection in rollover events, althoughno system can prevent all suchejections.
But airbags would not help in manytypes of collisions, primarilybecause the occupant's motion is
not toward those airbags. SeeWhen Should an AirbagInflate?059.
Airbags should never be regardedas anything more than a supplementto safety belts.
What Will You See after
an Airbag Inflates?
After the frontal airbags andseat-mounted side impact airbags (ifequipped) inflate, they quicklydeflate, so quickly that some peoplemay not even realize an airbaginflated. Roof-rail airbags (ifequipped) may still be at leastpartially inflated for some time afterthey deploy. Some components ofthe airbag module may be hot forseveral minutes. For location of theairbag modules, seeWhere Are theAirbags?057.
The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing out of

{Warning
When an airbag inflates, there
may be dust in the air. This dust

vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that mayautomatically unlock the doors(if equipped with power door locks),turn on the interior lamps andhazard warning flashers, and shutoff the fuel system after the airbags
inflate. The feature may alsoactivate, without airbag inflation,after an event that exceeds apredetermined threshold. You canlock the doors, and turn off theinterior lamps and the hazardwarning flashers by using thecontrols for those features.

the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.
Additional windshield breakage mayalso occur from the front outboardpassenger airbag.
.Airbags are designed to inflateonly once. After an airbaginflates, you will need some newparts for the airbag system.If you do not get them, the airbagsystem will not be there to helpprotect you in another crash.Anew system will include airbagmodules and possibly otherparts. The service manual forthe vehicle covers the need toreplace other parts.
.The vehicle has a crash sensingand diagnostic module whichrecords information after acrash. SeeVehicle DataRecording and Privacy0324andEvent DataRecorders0324.
.Let only qualified technicianswork on the airbag systems.Improper service can mean thatan airbag system will not workproperly. See your dealer forservice.

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicleshould be serviced. There are partsof the airbag system in severalplaces around the vehicle. Yourdealer and the service manual haveinformation about servicing thevehicle and the airbag system. Topurchase a service manual, seeService Publications OrderingInformation0321.
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal, may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,the airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,ceiling or pillar garnish trim, frontsensors, or airbag wiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0269for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect the
vehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any otherreason, call Customer Assistance.SeeCustomer AssistanceOffices0314.
Airbag System Check
The airbag system does not needregularly scheduled maintenance orreplacement. Make sure the airbagreadiness light is working. SeeAirbag Readiness Light099.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not

Child Restraints
Older Children
Older children who have outgrownbooster seats should wear thevehicle’ssafetybelts.
The manufacturer instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:
.Sit all the way back on the seat.Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.
.Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear safetybelt comfort guide, if available.See“Rear Safety Belt ComfortGuides”underLap-Shoulder Belt048.Ifacomfortguideisnotavailable, or if the shoulder beltstill does not rest on theshoulder, then return to thebooster seat.
.Does the lap belt fit low andsnug on the hips, touching thethighs? If yes, continue. If no,return to the booster seat.

Seats and Restraints 67
.Can proper safety belt fit bemaintained for the length of thetrip? If yes, continue. If no,return to the booster seat.
Q: What is the proper way towear safety belts?
A:An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the face orneck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force to thechild's pelvic bones in a crash.It should never be worn over theabdomen, which could causesevere or even fatal internalinjuries in a crash.
Also see“Rear Safety Belt ComfortGuides”underLap-ShoulderBelt048.
According to accident statistics,children are safer when properlyrestrained in a rear seating position.
In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can bethrown out of the vehicle. Olderchildren need to use safety beltsproperly.
{Warning
Never allow more than one child
to wear the same safety belt. The
safety belt cannot properly spread
the impact forces. In a crash, they
can be crushed together and
seriously injured. A safety belt
must be used by only one person
at a time.
{Warning
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly. In a
crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury. The child
might also slide under the lap
belt. The belt force would then be
applied right on the abdomen.

Warning (Continued)
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Infants and Young
Children
Everyone in a vehicle needsprotection! This includes infants andall other children. Neither thedistance traveled nor the age andsize of the traveler changes theneed, for everyone, to use safety
restraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’sneck.
If the shoulder belt is locked and
tightened around a child’sneck,
the only way to loosen the belt is
to cut it.
Never leave children unattended
in a vehicle and never allow
children to play with the safety
belts.
Every time infants and youngchildren ride in vehicles, they shouldhave the protection provided byappropriate child restraints. Neitherthe vehicle's safety belt system norits airbag system is designedfor them.
Children who are not restrainedproperly can strike other people,or can be thrown out of the vehicle.
{Warning
Never hold an infant or a child
while riding in a vehicle. Due to
crash forces, an infant or a child
will become so heavy it is not
possible to hold it during a crash.
For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb)
infant will suddenly become a
11 0 k g ( 2 4 0 l b ) f o r c e o n a p e r s o n ' s
arms. An infant or child should be
secured in an appropriate
restraint.

Seats and Restraints 69
{Warning
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Never put a rear-facing
child restraint in the front
outboard seat. Secure a
rear-facing child restraint in a rear
seat. It is also better to secure a
forward-facing child restraint in a
rear seat. If you must secure a
forward-facing child restraint in
the front outboard seat, always
move the front passenger seat as
far back as it will go.
Child restraints are devices used torestrain, seat, or position children inthe vehicle and are sometimescalled child seats or car seats.
There are three basic types ofchild restraints:
.Forward-facing child restraints
.Rearward-facing child restraints
.Belt-positioning booster seats
The proper child restraint for yourchild depends on their size, weight,and age, and also on whether thechild restraint is compatible with thevehicle in which it will be used.
For each type of child restraint,there are many different modelsavailable. When purchasing a childrestraint, be sure it is designed to beused in a motor vehicle. If it is, therestraint will have a label saying thatit meets federal motor vehicle safetystandards. The restraintmanufacturer's instructions thatcome with the restraint state theweight and height limitations for aparticular child restraint. In addition,there are many kinds of restraintsavailable for children with specialneeds.
{Warning
To r e d u c e t h e r i s k o f n e c k a n d
head injury in a crash, infants and
toddlers should be secured in a
rear-facing child restraint until age
two, or until they reach the
maximum height and weight limits
of their child restraint.
