indicator will light and stay lit
as a reminder that the airbags
are 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
front outboard passenger
frontal airbag and knee airbag,
depending upon the person's
seating posture and body
build. Everyone in the vehicle
who has outgrown child
restraints should wear a seat
belt properly—whether or not
there is an 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

Light0124 for more
information, including
important safety
information.
If the On Indicator Is Lit
for a Child Restraint
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee airbag,
if the system determines that
an infant is present in a child
restraint. If a child restraint
has been installed and the ON
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such
as blankets, cushions, seat
covers, seat heaters,
or seat massagers. 4. Reinstall the child restraint
following the directions
provided by the child
restraint manufacturer and
refer to Securing Child
Restraints (With the Seat
Belt in the Rear Seat) 095
or Securing Child
Restraints (With the Seat
Belt in the Front Seat)
0 98.
Make sure the seat belt
retractor is locked by
pulling the shoulder belt all
the way out of the
retractor when installing
the child restraint, even if
the child restraint is
equipped with a seat belt
lock off. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor.
5. If, after reinstalling the child restraint and
restarting the vehicle, the
ON indicator is still lit, turn
the vehicle off. Then
slightly recline the vehicle

seatback and adjust the
seat cushion, if adjustable,
to make sure that the
vehicle seatback is not
pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped
under the vehicle head
restraint. If this happens,
adjust the head restraint.
See Head Restraints045.
6. Restart the vehicle.
The passenger sensing
system may or may not turn
off the airbag for a child in a
child restraint depending upon
the child’s size. It is better to
secure the child restraint in a
rear seat. Never put a
rear-facing child restraint in
the front seat, even if the ON
indicator is not lit.If the Off Indicator Is Lit
for an Adult-Sized
Occupant
If a person of adult size is
sitting in the front outboard
passenger seat, but the OFF
indicator is lit, it could be
because that person is not
sitting properly in the seat or
that the child restraint locking
feature is engaged. Use the
following steps to allow the
system to detect that person
and enable the front outboard
passenger frontal airbag and
knee 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. 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-sized
occupants. If this happens,
unbuckle the belt, let the
belt go back all the way,
and then buckle the belt
again without pulling the
belt out all the way.

{Warning
Children can be seriously
injured or killed if the
shoulder belt is worn behind
their back, under their legs,
or wrapped around their
neck. The shoulder belt can
tighten but cannot be
loosened if it is locked. The
shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when
the shoulder belt is allowed
to go all the way back into
the retractor, but it cannot
do this if it is wrapped
around the child. Never
leave children unattended in
a vehicle and never allow
children to improperly wear,
or play with, the seat belts.
Every time infants and young
children ride in vehicles, they
should have the protection
provided by appropriate child
restraints. Neither the vehicle's seat belt system nor
its airbag system is designed
for them.
Children who are not
restrained properly 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
110 kg (240 lb) force on a
person's arms. An infant or
child should be secured in an
appropriate child 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 to restrain, seat,
or position children in the
vehicle and are sometimes
called child seats or car seats.
There are three basic types
of child restraints:
.Forward-facing child
restraints
.Rear-facing child restraints
.Belt-positioning booster
seats
The proper child restraint for
your child depends on their
size, weight, and age, and also
on whether the child restraint
is compatible with the vehicle
in which it will be used.
For each type of child
restraint, there are many
different models available.
When purchasing a child
restraint, be sure it is
designed to be used in a
motor vehicle and is designed
by a genuine child restraint
manufacturer. If it is, the child
restraint will have a label
saying that it meets federal
motor vehicle safety
standards.
The instruction manual that is
provided with the child
restraint states the weight
and height limitations for that
particular child restraint. In
addition, there are many kinds
of child restraints available for
children with special needs.{Warning
To reduce the risk of neck
and 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
A young child's hip bones
are still so small that the
vehicle seat 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, (Continued)

young children should
always be secured in an
appropriate child restraint.
Child Restraint
Systems
Rear-Facing Infant Restraint
A rear-facing child restraint
provides restraint with the
seating surface against the
back of the infant. The harness system holds the
infant in place and, in a crash,
acts to keep the infant
positioned in the restraint.
Forward-Facing Child
Restraint
A forward-facing child
restraint provides restraint for
the child's body with the
harness.
Booster Seats
A belt-positioning booster
seat is used for children who
have outgrown their
forward-facing child restraint.
Boosters are designed to
improve the fit of the vehicle's
seat belt system until the child
is large enough for the vehicle
seat belts to fit properly
without a booster seat. See
the seat belt fit test in Older
Children 079.

Securing an Add-On Child
Restraint in the Vehicle
{Warning
A child can be seriously
injured or killed in a crash if
the child restraint is not
properly secured in the
vehicle. Secure the child
restraint properly in the
vehicle using the vehicle
seat belt or LATCH system,
following the instructions
that came with that child
restraint and the
instructions in this manual.
To help reduce the chance of
injury, the child restraint must
be secured in the vehicle. Child
restraints must be secured in
vehicle seats by lap belts or
the lap belt portion of a
lap-shoulder belt, or by the
LATCH system. See Lower
Anchors and Tethers for
Children (LATCH System) 086
for more information. Never
use a seat belt extender when installing a child restraint.
Never use non-regulated
aftermarket anchors or
attachments to secure a child
restraint. Children can be
endangered in a crash if the
child restraint is not properly
secured in the vehicle.
When securing an add-on child
restraint, refer to the
following:
1. Instruction labels provided on the child restraint
2. Instruction manual provided with the child
restraint
3. This vehicle owner's manual
The child restraint instructions
are important, so if they are
not available, obtain a
replacement copy from the
manufacturer.
Keep in mind that an
unsecured child restraint can
move around in a collision or
sudden stop and injure people
in the vehicle. Be sure to properly secure any child
restraint in the vehicle
—even
when no child is in it.
In some areas Certified Child
Passenger Safety Technicians
(CPSTs) are available to
inspect and demonstrate how
to correctly use and install
child restraints. In the U.S.,
refer to the National Highway
Traffic Safety Administration
(NHTSA) website to locate the
nearest child safety seat
inspection station. For CPST
availability in Canada, check
with Transport Canada or the
Provincial Ministry of
Transportation office.

Warning (Continued)
properly following the
instructions that came with
that child restraint.
Where to Put the
Restraint
According to accident
statistics, children and infants
are safer when properly
restrained in an appropriate
child restraint secured in a
rear seating position.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.
Never put a rear-facing child
restraint in the front. This is
because the risk to the
rear-facing child is so great if
the airbag deploys.
{Warning
A child in a rear-facing child
restraint can be seriously
injured or killed if the front
passenger 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 front passenger airbag
inflates and the passenger
seat is in a forward position.
Even if the passenger
sensing system has turned
off the 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 it is turned off.(Continued)
Warning (Continued)
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 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.
See Passenger Sensing
System072 for additional
information.
When securing a child
restraint with the seat belts in
a rear seat position, study the
instructions that came with
the child restraint to make
sure it is compatible with this
vehicle.

86 Seats and Restraints
Child restraints and booster
seats vary considerably in size,
and some may fit in certain
seating positions better than
others. Do not install a child
restraint in any rear seating
position where it cannot be
installed securely.
Depending on where you place
the child restraint and the size
of the child restraint, you may
not be able to access adjacent
seat belts or LATCH anchors
for additional passengers or
child restraints. Adjacent
seating positions should not
be used if the child restraint
prevents access to or
interferes with the routing of
the seat belt.
The seat in front of an
installed child restraint should
be adjusted to ensure proper
installation according to the
child restraint manual.Wherever a child restraint is
installed, be sure to follow the
instructions that came with
the child restraint and secure
the child restraint properly.
Keep in mind that an
unsecured child restraint can
move around in a collision or
sudden stop and injure people
in the vehicle. Be sure to
properly secure any child
restraint in the vehicle
—even
when no child is in it.
Lower Anchors and
Tethers for Children
(LATCH System)
The LATCH system secures a
child restraint during driving or
in a crash. LATCH
attachments on the child
restraint are used to attach
the child restraint to the
anchors in the vehicle. This
system is designed to make
installation of a child restraint
easier. In order to use the LATCH
system in your vehicle, you
need a child restraint that has
LATCH attachments.
LATCH-compatible rear-facing
and forward-facing child seats
can be properly installed using
either the LATCH anchors or
the vehicle’s seat belts. Do not
use both the seat belts and
the LATCH anchorage system
to secure a rear-facing or
forward-facing child restraint.
Booster seats use the
vehicle’s seat belts to secure
the child and the booster seat.
If the manufacturer
recommends that the booster
seat be secured with the
LATCH system, this can be
done as long as the booster
seat can be positioned
properly and there is no
interference with the proper
positioning of the lap-shoulder
belt on the child.
