system's deployment threshold.Deployment thresholds are used topredict how severe a crash is likelyto be in time for the airbags toinflate and help restrain theoccupants. The vehicle haselectronic sensors which help theairbag system determine theseverity of the impact. Deploymentthresholds can vary with specificvehicle design.
Frontal airbags are designed toinflate in moderate to severe frontalor near frontal crashes to helpreduce the potential for severeinjuries, mainly to the driver's orfront outboard passenger's headand chest.
Whether the frontal airbags will orshould inflate is not based primarilyon how fast the vehicle is traveling.It depends on what is hit, thedirection of the impact, and howquickly the vehicle slows down.
Frontal airbags may inflate atdifferent crash speeds depending onwhether the vehicle hits an objectstraight on or at an angle, and
whether the object is fixed ormoving, rigid or deformable, narrowor wide.
Frontal airbags are not intended toinflate during vehicle rollovers, inrear impacts, or in many sideimpacts.
In addition, if the GVWR (GrossVehicle Weight Rating) is at orbelow 3 855 kg (8,500 lb), thevehicle has advanced technologyfrontal airbags. You can find theGVWR on the Certification/Tire labelon the center pillar of the vehicle.SeeVehicle Load Limits0259formore information.
Advanced technology frontal airbagsadjust the restraint according tocrash severity. Vehicles withadvanced technology frontal airbagshave a seat position sensor thatenables the sensing system tomonitor the position of the driverseat. The seat position sensorprovides information that is used toadjust the deployment of the driverfrontal airbag.
If the GVWR is at or below 4 536 kg(10,000 lb), the vehicle hasseat-mounted side impact airbags.Vehicles with a GVWR above4536kg (10,000lb) may or may nothave seat-mounted side impactairbags. Seat-mounted side impactairbags, if equipped, are designedto inflate in moderate to severe sidecrashes depending on the locationof the impact. Seat-mounted sideimpact airbags are not designed toinflate in frontal impacts, near frontalimpacts, rollovers, or rear impacts.Aseat-mountedsideimpactairbagis designed to inflate on the side ofthe vehicle that is struck.
Vehicles with a GVWR at or below3855kg (8,500lb) have roof-railairbags. These roof-rail airbags aredesigned to inflate in moderate tosevere side crashes depending onthe location of the impact. Inaddition, these roof-rail airbags aredesigned to inflate during a rolloveror in a severe frontal impact. Theroof-rail airbags are not designed toinflate in rear impacts. Both roof-railairbags will inflate when either sideof the vehicle is struck or if the

The passenger sensing systemturns off the front outboardpassenger frontal airbag undercertain conditions. No other airbagis affected by the passengersensing system.
The passenger sensing systemworks with sensors that are part ofthe front outboard passenger seatand safety belt. The sensors aredesigned to detect the presence ofaproperlyseatedoccupantanddetermine if the front outboardpassenger frontal airbag should beallowed to inflate or not.
According to accident statistics,children are safer when properlysecured in a rear seat in the correctchild restraint for their weightand size.
Whenever possible, children aged12 and under should be secured inarearseatingposition.
Never put a rear-facing child seat inthe front. This is because the risk tothe rear-facing child is so great,if the airbag deploys.
{Warning
Achildinarear-facingchild
restraint can be seriously injured
or killed if the passenger frontal
airbag inflates. This is because
the back of the rear-facing child
restraint would be very close to
the inflating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag is turned off.
Never put a rear-facing child
restraint in the front seat, even if
the airbag is off. If securing a
forward-facing child restraint in

the front outboard passenger
seat, always move the seat as far
back as it will go. It is better to
secure child restraints in the rear
seat. Consider using another
vehicle to transport the child
when a rear seat is not available.
If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.
The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag if:
.The front outboard passengerseat is unoccupied.
.The system determines an infantis present in a child restraint.
.Afrontoutboardpassengertakes his/her weight off of theseat for a period of time.

Child Restraints
Older Children
Older children who have outgrownbooster seats should wear thevehicle safety belts.
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:

the 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.
{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.

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.
{Warning
Ayoungchild'shipbonesarestill
so small that the vehicle's regular
safety belt may not remain low on
the hip bones, as it should.
Instead, it may settle up around
the child's abdomen. In a crash,
the belt would apply force on a
body area that is unprotected by
any bony structure. This alone
could cause serious or fatal
injuries. To reduce the risk of
serious or fatal injuries during a
crash, young children should
always be secured in appropriate
child restraints.

Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system secures a childrestraint during driving or in a crash.LATCH attachments on the childrestraint are used to attach the childrestraint to the anchors in thevehicle. This system is designed tomake installation of a child restrainteasier.
In order to use the LATCH system inyour vehicle, you need a childrestraint that has LATCHattachments. LATCH-compatiblerear-facing and forward-facing childseats can be properly installedusing either the LATCH anchors orthe vehicle’ssafetybelts.Donotuse both the safety belts and theLATCH anchorage system to securearear-facingorforward-facingchild seat.
Booster seats use the vehicle’ssafety belts to secure the child inthe booster seat. If the manufacturerrecommends that the booster seatbe secured with the LATCH system,this can be done as long as thebooster seat can be positionedproperly and there is no interferencewith the proper positioning of thelap-shoulder belt on the child.
Make sure to follow the instructionsthat came with the child restraint,and also the instructions in thismanual.
When installing a child restraint withatoptether,youmustalsouseeither the lower anchors or thesafety belts to properly secure thechild restraint. A child restraint mustnever be attached using only the toptether.
The LATCH anchorage system canbe used until the combined weightof the child plus the child restraint is29.5 kg (65 lbs). Use the safety beltalone instead of the LATCHanchorage system once thecombined weight is more than29.5 kg (65 lbs).
SeeSecuring Child Restraints (Withthe Safety Belt in the Center FrontSeat)0106orSecuring ChildRestraints (With the Safety Belt inthe Rear Seat)0102orSecuringChild Restraints (With the SafetyBelt in the Front PassengerSeat)0106.
Child restraints built after March2014 will be labeled with thespecific child weight up to which theLATCH system can be used toinstall the restraint.
