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 and check with your dealer.
To remove the child restraint, just 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.Securing a Child Restraint in the
Right Front Seat Position (Heavy
Duty Crew Cab Only)
Your vehicle has a right front passenger airbag.
Neverput a rear-facing child restraint in the
right front passenger’s seat. Here is why:
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag in ates. This is
because the back of the rear-facing child
restraint would be very close to the
in ating airbag. Always secure a
rear-facing child restraint in a rear seat.
A rear seat is a safer place to secure a
forward-facing child restraint. If you need to
secure a forward-facing child restraint in the right
front seat position, seeWhere to Put the
Restraint on page 56.

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 250for more information.Where Are the Airbags?
The driver’s airbag is in the middle of the steering
wheel.

In many crashes severe enough to in ate the
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger
airbag.
Airbags are designed to in ate only once.
After an airbag in ates, you will need
some new parts for your airbag system. If you
do not get them, the airbag system will not
be there to help protect you in another crash.
A new system will include airbag modules
and possibly other parts. The service manual
for your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 656.
Let only quali ed technicians work on the
airbag system. Improper service can mean that
an airbag system will not work properly. See
your dealer for service.
Airbag Off Switch
If one of the switches pictured in the following
illustrations is located in your glove box, your
vehicle has an airbag on-off switch that you can
use to manually turn on or off the right front
passenger’s airbag. Your switch may vary slightly.
If your vehicle does not have an airbag off switch,
it may have a passenger sensing system. See
Passenger Sensing System.

{CAUTION:
If the right front passenger’s airbag is
turned off for a person who is not in a risk
group identi ed by the national
government, that person will not have the
extra protection of an airbag. In a crash,
the airbag will not be able to in ate and
help protect the person sitting there. Do
not turn off the passenger’s airbag unless
the person sitting there is in a risk group.
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 word OFF or the off symbol will come on in
the passenger airbag status indicator located in the
overhead console to let you know that the right
front passenger’s airbag is off, after the system
check is completed. The airbag off light will come
on and stay on to let you know that the right
front passenger’s airbag is off. SeeAirbag Off Light
on page 250.

{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 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 the right front
passenger’s seat) until you have your
vehicle serviced. SeeAirbag Readiness
Light on page 250for additional
information.To turn the right front passenger’s airbag on
again, insert your ignition key into the switch, push
in, and move the switch to the on position.
The right front passenger’s frontal airbag is now
enabled (may in ate). SeeAirbag Off Light
on page 250for more information.

The passenger sensing system is designed to turn
off the right front passenger’s airbag if:
The right front passenger seat is unoccupied
The system determines that an infant is
present in a rear-facing infant seat
The system determines that a small child is
present in a child restraint
The system determines that a small child is
present in a booster seat
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 right front 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 thechild restraint following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
(With Airbag Off Switch) on page 70orSecuring a
Child Restraint in the Right Front Seat Position
(With Passenger Sensing System) on page 76.
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.
Remove any additional material from the seat
cushion before reinstalling or securing the
child restraint.
If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the
vehicle, and check with your dealer/retailer.
If no rear seat is available, do not install a child
restraint in this vehicle, and check with your
dealer/retailer.

The passenger sensing system is designed to
enable (may in ate) the right front passenger’s
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 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 two to three minutes. This will
allow the system to detect that person and then
enable the right front passenger’s frontal airbag.
Safety belts help keep the passenger in position
on the seat during vehicle maneuvers and braking,
which helps the passenger sensing system
maintain the passenger airbag status.

See “Safety Belts” and “Child Restraints” in the
Index for additional information about the
importance of proper restraint use.
{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 airbag(s). SeeAirbag
Readiness Light on page 250for more on
this, including important safety
information.A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates. You may want to consider not
using seat covers or other aftermarket equipment.
SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 102for more information
about modi cations that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.

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. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 601for 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,
or the side impact airbag covering on the
ceiling near the side windows, the airbag may
not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or
side impact airbag module and ceiling covering
for roof-mounted rollover airbags (if equipped).
Do not open or break the airbag coverings.

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
in your vehicle. A damaged restraint
system may not properly protect the
person using it, resulting in serious injury
or even death in a crash. To help make sure
your restraint systems are working
properly after a crash, have them inspected
and any necessary replacements made as
soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be
necessary. But if the belts were stretched, as they
would be if worn during a more severe crash,
then you need new parts.
If the LATCH system was being used during a
more severe crash, you may need new LATCH
system parts.If belts are cut or damaged, replace them.
Collision damage also may mean you will need to
have LATCH system, safety belt or seat parts
repaired or replaced. New parts and repairs may
be necessary even if the belt or LATCH system
was not being used at the time of the collision.
If an airbag in ates, you will need to replace airbag
system parts. See the part on the airbag system
earlier in this section.
If the frontal airbags in ate you will also need to
replace the driver and front passenger’s safety belt
retractor assembly. Be sure to do so. Then the
new retractor assembly will be there to help protect
you in a collision.
After a crash you may need to replace the driver
and front passenger’s safety belt retractor
assemblies, even if the frontal airbags have not
deployed. The driver and front passenger’s safety
belt retractor assemblies contain the safety belt
pretensioners. Have your safety belt pretensioners
checked if your vehicle has been in a collision,
or if your airbag readiness light stays on after you
start your vehicle or while you are driving. See
Airbag Readiness Light on page 250.
