For more information,see the instruction sheet that comeswith the extender.
Safety System Check
Check that the safety belt reminder,safety belts, buckles, latch plates,and retractors, are all workingproperly. Look for any other loose ordamaged safety belt system partsthat might keep a safety belt systemfrom performing properly. See yourdealer to have it repaired. Torn orfrayed safety belts may not protectyou in a crash. They can rip apartunder impact forces. If a belt is tornor frayed, have it replacedimmediately.
Make sure the safety belt reminderlight is working. SeeSafety BeltReminders0134.

Warning (Continued)
seriously injured or killed. Do not
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 system checks the airbagelectrical system for malfunctions.The light tells you if there is anelectrical problem. SeeAirbagReadiness Light0135for moreinformation.
Where Are the Airbags?
The driver frontal airbag is in thecenter of the steering wheel.

{Warning
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury

Warning (Continued)
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie⇣down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
This vehicle is equipped withairbags. SeeAirbag System074.Airbags are designed to inflate if theimpact exceeds the specific airbag

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
(Continued)
Warning (Continued)
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,
