Securing a Child Restraint in the
Right Front Seat Position (Heavy
Duty Crew Cab Only)
Your vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-48.
A label on the sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to
the rear-facing child is so great, if the airbag deploys.
Neverput a rear-facing child restraint in the right
front passenger 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 inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. Always secure a
rear-facing child restraint in a rear seat.If the vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, a rear-facing
child restraint should not be installed in the vehicle,
even if the airbag is off.
If your child restraint has the LATCH system, seeLower
Anchors and Tethers for Children (LATCH) on page 1-49
for how and where to install your child restraint using
LATCH. If you secure a child restraint using a safety belt
and it uses a top tether, seeLower Anchors and Tethers
for Children (LATCH) on page 1-49for top tether anchor
locations.
Do not secure a child seat in a position without a top
tether anchor 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 strap must be
anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions that
came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
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. Push the latch plate into the buckle until it clicks.
Make sure the release button is positioned so you
would be able to unbuckle the safety belt quickly
if necessary.5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.
1-71

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. If you are using a forward-facing
child restraint, you may nd it helpful to use your
knee to push down on the child restraint as you
tighten the belt.7. If your child restraint has a top tether, follow the
child restraint manufacturer’s instructions regarding
the use of the top tether. SeeLower Anchors
and Tethers for Children (LATCH) on page 1-49for
more information.
8. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle safety
belt and let it return to the stowed position. If the top
tether is attached to a top tether anchor, disconnect it.
Airbag System
The vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
The vehicle may have the following airbags:
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the person seated directly behind the right front
passenger.
1-72

Page 79 of 602

All of the airbags in the vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s airbags
are also designed to help reduce the risk of injury
from the force of an inating bag, all airbags must inate
very quickly to do their job.Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash if
you are not wearing your safety belt — even if you
have airbags. Airbags are designed to work with
safety belts, but do not replace them. Also, airbags
are not designed to deploy in every crash. In some
crashes safety belts are your only restraint. See
When Should an Airbag Inflate? on page 1-77.
Wearing your safety belt during a crash helps
reduce your chance of hitting things inside the
vehicle or being ejected from it. Airbags are
“supplemental restraints” to the safety belts.
Everyone in your vehicle should wear a safety belt
properly — whether or not there is an airbag for that
person.
1-73

Page 80 of 602

{CAUTION:
Airbags inate with great force, faster than the
blink of an eye. Anyone who is up against, or very
close to, any airbag when it inates can be
seriously injured or killed. Do not sit unnecessarily
close to the airbag, as you would be if you were
sitting on the edge of your seat or leaning forward.
Safety belts help keep you in position before and
during a crash. Always wear your safety belt, even
with airbags. The driver should sit as far back as
possible while still maintaining control of the
vehicle.
Occupants should not lean on or sleep against the
door or side windows in seating positions with
roof-rail airbags.
{CAUTION:
Children who are up against, or very close to, any
airbag when it inates can be seriously injured or
killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, but not for
young children and infants. Neither the vehicle’s
safety belt system nor its airbag system is designed
for them. Young children and infants need the
protection that a child restraint system can provide.
Always secure children properly in your vehicle. To
read how, seeOlder Children on page 1-38or
Infants and Young Children on page 1-41.
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 3-37
for more information.
1-74

What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inator. Gas from the inator lls the airbag causing the
bag to break out of the cover and deploy. The inator, the
airbag, and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with roof-rail
airbags, there are airbag modules in the ceiling of the
vehicle, near the side windows that have occupant
seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. Roof-rail airbags distribute
the force of the impact more evenly over the occupant’s
upper body.
Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the outboard
seating positions in the rst and second rows. The
rollover capable roof-rail airbags are designed to help
reduce the risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-77for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.

This switch should only be turned to the off position if
the person in the right front passenger position is a
member of a passenger risk group identied by
the national government as follows:
Infant.An infant (less than 1 year old) must
ride in the front seat because:

My vehicle has no rear seat;
My vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
The infant has a medical condition which, according
to the infant’s physician, makes it necessary for the
infant to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Child age 1 to 12.A child age 1 to 12 must
ride in the front seat because:

My vehicle has no rear seat;
Although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children ages 1 to 12
sometimes must ride in the front because no space
is available in the rear seat(s) of my vehicle; or
The child has a medical condition which, according
to the child’s physician, makes it necessary for the
child to ride in the front seat so that the driver
can constantly monitor the child’s condition.
Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

Causes the passenger airbag to pose a special risk
for the passenger; and
Makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing the
passenger, even if belted, to hit the dashboard
or windshield in a crash.
{CAUTION:
If the right front passenger’s airbag is turned off for
a person who is not in a risk group identied 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 inate 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.

The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag and the roof-rail airbags (if equipped)
are not affected by the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat and safety
belt. The sensors are designed to detect the presence
of a properly-seated occupant and determine if the
right front passenger frontal airbag should be enabled
(may inate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to
the rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inates. This is because the back of the
rear-facing child restraint would be very close to the
inating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front 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.
Secure rear-facing child restraints in a rear seat,
even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint in
a rear seat.
1-85

If the vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, a rear-facing
child restraint should not be installed in the vehicle, even
if the airbag is off.
The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
The right front passenger seat is unoccupied.
The system determines an infant is present in a
child restraint.
A right front passenger takes his/her weight off of
the seat for a period of time.
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 frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off. See
Passenger Airbag Status Indicator on page 3-40.
The passenger sensing system is designed to turn on
(may inate) the right front passenger frontal airbag
anytime the system senses that a person of adult size is
sitting properly in the right front passenger 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, including children in child restraints,
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger 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.{CAUTION:
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 Light on page 3-37
for more information, including important safety
information.

If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in the right front
passenger seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat.If this happens, use the following steps to allow the
system to detect that person and enable the right front
passenger frontal airbag:
1. Turn the vehicle off.
2. Remove any additional material from the seat, such
as blankets, cushions, seat covers, seat heaters, or
seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on
the seat cushion, with legs comfortably extended.
5. Restart the vehicle and have the person remain in
this position for two to three minutes after the on
indicator is lit.
Additional Factors Affecting System
Operation
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.
If the shoulder portion of the belt is pulled out all the way,
the child restraint locking feature will be engaged. This
may unintentionally cause the passenger sensing system
to turn the airbag off for some adult size occupants. If this
happens, let the belt go back all the way and start again.
