sit unnecessarily close to any
airbag, as you would be if sitting
on the edge of the seat or leaning
forward. Safety belts help keep
you in position before and during
acrash.Alwayswearasafety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle. The safety belts and
the front outboard passenger
airbags are most effective when
you are sitting well back and
upright in the seat with both feet
on the floor.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Always secure children
properly in the vehicle. To read
how, seeOlder Children088or
Infants and Young Children090.
There is an airbag readiness lighton the instrument cluster, whichshows the airbag symbol.

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.

.There is a critical problem withthe airbag system or thepassenger sensing system.
When the passenger sensingsystem has turned off the frontoutboard passenger frontal airbag,the off indicator will light and stay litas a reminder that the airbag is off.SeePassenger Airbag StatusIndicator0137.
The passenger sensing system isdesigned to turn on the frontoutboard passenger frontal airbaganytime the system senses that aperson of adult size is sittingproperly in the front outboardpassenger seat.
When the passenger sensingsystem has allowed the airbag to beenabled, the on indicator will lightand stay lit as a reminder that theairbag is active.
For some children, includingchildren in child restraints, and forvery small adults, the passengersensing system may or may not turnoff the front outboard passenger
frontal airbag, depending upon theperson's seating posture and bodybuild. Everyone in the vehicle whohas outgrown child restraints shouldwear a safety beltproperly—whether or not there isan airbag for that person.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light0135for more information,
including important safety
information.
If the On Indicator Is Lit for a
Child Restraint
The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag ifthe system determines that an infant
is present in a child restraint. If achild restraint has been installedand the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint fromthe vehicle.
3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.
4. Reinstall the child restraintfollowing the directionsprovided by the child restraintmanufacturer and refer toSecuring Child Restraints (Withthe Safety Belt in the CenterFront Seat)0106orSecuringChild Restraints (With theSafety Belt in the Rear Seat)0102orSecuring ChildRestraints (With the Safety Beltin the Front PassengerSeat)0106.
Make sure the safety beltretractor is locked by pullingthe shoulder belt all the wayout of the retractor wheninstalling the child restraint,

even if the child restraint isequipped with a safety beltlock-off. When the retractorlock is set, the belt can betightened but not pulled out ofthe retractor.
5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator is stilllit, turn the vehicle off. Thenslightly recline the vehicleseatback and adjust the seatcushion, if adjustable, to makesure that the vehicle seatbackis not pushing the childrestraint into the seat cushion.
Also make sure the childrestraint is not trapped underthe vehicle head restraint.If this happens, adjust the headrestraint. SeeHeadRestraints057.
6. Restart the vehicle.
The passenger sensing system mayor may not turn off the airbag for achild in a child restraint dependingupon the child’ssize.Itisbettertosecure child restraints in the rearseat. Consider using another
vehicle to transport the child when arear seat is not available. Never putarear-facingchildrestraintinthefront seat, even if the on indicator isnot lit.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting inthe front outboard passenger seat,but the off indicator is lit, it could bebecause that person is not sittingproperly in the seat or that the childrestraint locking feature is engaged.If this happens, use the following
steps to allow the system to detectthat person and enable the frontoutboard passenger frontal airbag:
1. Turn the vehicle off.
2. Remove any additional materialfrom the seat, such asblankets, cushions, seatcovers, seat heaters, or seatmassagers.
3. Place the seatback in the fullyupright position.
4. Have the person sit upright inthe seat, centered on the seatcushion, with legs comfortablyextended.
5. If the shoulder portion of thebelt is pulled out all the way,the child restraint lockingfeature will be engaged. Thismay unintentionally cause thepassenger sensing system toturn the airbag off for someadult-sized occupants. If thishappens, unbuckle the belt, letthe belt go back all the way,and then buckle the belt againwithout pulling the belt out allthe way.

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.
{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.
{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.
