If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeeAirbag Off Switch on
page 100. If your child restraint is
forward-facing, move the seat as far back as
it will go before securing the restraint in
this seat. SeeManual Seats on page 9or
Power Seats on page 10. If you need to use a
rear-facing child restraint in this seat, make
sure the airbag is off once the child restraint
has been installed.
When the airbag off switch has turned off the
right front passenger’s frontal airbag, the
off indicator in the airbag off light should light
and stay lit when you turn the ignition to
RUN or START. SeeAirbag Off Light on
page 248.
2. Put the child restraint on the seat.

If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.
You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 103. We recommend that
rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the
child restraint in this seat. SeePower Seats
on page 10orManual Seats on page 9.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger airbagstatus indicator should light and stay lit when
you turn the ignition to RUN or START.
SeePassenger Airbag Status Indicator on
page 250.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.

7. If your child restraint manufacturer
recommends using a top tether, and the
position you are using has a top tether anchor,
attach and tighten the top tether to the top
tether anchor. Refer to the instructions
that came with the child restraint and toLower
Anchors and Tethers for Children (LATCH)
on page 58.
8. Push and pull the child restraint in different
directions to be sure it is secure.
9. If your vehicle has a passenger sensing
system and the airbag is off, the off indicator in
the inside rearview mirror will be lit and stay
lit when the key is turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove
the child restraint from the vehicle and reinstall the
child restraint.If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the
child restraint into the seat cushion. If this happens,
slightly recline the vehicle’s seatback and adjust the
seat cushion if possible. Also make sure the child
restraint is not trapped under the vehicle head
restraint. If this happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle if
one is available and check with your dealer.
To remove the child restraint, if the top tether is
attached to the top tether anchor, disconnect
it. Unbuckle the vehicle’s safety belt and let it go
back all the way. The safety belt will move
freely again and be ready to work for an adult or
larger child passenger.

There is an airbag
readiness light on the
instrument panel cluster,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 247for more information.Where Are the Airbags?
The driver’s airbag is in the middle of the steering
wheel.

To turn off the right front passenger’s airbag,
insert your ignition key into the switch, push in, and
move the switch to the off position.
The airbag off light will come on to let you know
that the right front passenger’s airbag is off.
The light will stay on to remind you that the airbag
is off. The right front passenger’s airbag will
remain off until you turn it back on.
{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could in ate even
though the switch is off.
If your vehicle is a regular cab pickup or
an extended cab pickup and this ever
happens, do not let anyone whom the
national government has identi ed as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in your vehicle) until you
have your vehicle serviced. SeeAirbag
Readiness Light on page 247for
additional information.

A right front passenger takes his/her weight off
of the seat for a period of time.
The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off
the passenger’s frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove
the child restraint from the vehicle and reinstall the
child restraint following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
(Regular and Extended Cab) (With Passenger
Sensing System)in the Index.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to
make sure that the vehicle’s seatback is not
pressing the child restraint into the seat cushion. If
this happens, slightly recline the vehicle’s
seatback and adjust the seat cushion if possible.Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle if
one is available and check with your dealer.
The passenger sensing system is designed to
enable (may in ate) the right front passenger’s
frontal airbag anytime the system senses
that a person of adult size is sitting properly in the
right front passenger’s seat. When the passenger
sensing system has allowed the airbag to be
enabled, the on indicator will light and stay lit to
remind you that the airbag is active.
For some children who have outgrown child
restraints and for very small adults, the passenger
sensing system may or may not turn off the
right front passenger’s frontal airbag, depending
upon the person’s seating posture and body build.
Everyone in your vehicle who has outgrown
child restraints should wear a safety belt
properly — whether or not there is an airbag for
that person.

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could
be because that person is not sitting properly in the
seat. If this happens, turn the vehicle off and ask
the person to place the seatback in the fully upright
position, then sit upright in the seat, centered on the
seat cushion, with the person’s legs comfortably
extended. Restart the vehicle and have the person
remain in this position for about two minutes. This
will allow the system to detect that person and then
enable the right front passenger’s airbag.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system. If
this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the frontal airbag. See
Airbag Readiness Light on page 247for
more on this, including important safety
information.

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. SeeCare of Safety Belts on page 592
for more information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.
Also look for any opened or broken airbag
covers, and have them repaired or replaced. The
airbag system does not need regular maintenance.Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
the airbag may not work properly. You may
have to replace the airbag module in the
steering wheel or both the airbag module and
the instrument panel for the right front
passenger’s airbag. Do not open or break the
airbag coverings.
