3-30 Seats and Restraints
The right front passenger frontal
airbag is in the instrument panel on
the passenger's side.Driver Side shown, PassengerSide similar
The roof-rail airbags for the
driver, right front passenger, and
second row outboard passengers
are in the ceiling above the side
windows.
{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
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.
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.

Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be visible
on the instrument panel when the
vehicle is started.
United States
Canada
The words ON and OFF, or the
symbol for on and off, are visible
during the system check. When the
system check is complete, the word ON or OFF, or the symbol for on or
off, will be visible. See
Passenger
Airbag Status Indicator
on
page 5‑11.
The passenger sensing system will
turn off the right front passenger
frontal airbag under certain
conditions. The driver airbags and
the roof-rail airbags 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 inflate) 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.

3-36 Seats and Restraints
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.
{WARNING
A child in a rear-facing child
restraint can be seriously
injured or killed if the right
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 right front
passenger airbag inflates and the
passenger seat is in a forward
position.
(Continued)
WARNING (Continued)
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. 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 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.

3-38 Seats and Restraints
If the On Indicator is Lit for 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 fromthe 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 (Rear
Outboard Seating Position)
on
page 3‑59or Securing Child
Restraints (Rear Center Seating
Position)
on page 3‑61or
Securing Child Restraints (Right
Front Seat Position)
on
page 3‑62. 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 Restraints
on page 3‑2.
6. Restart the vehicle.
If the on indicator is still lit with a
child present in a child restraint,
secure the child restraint in a
rear seat position in the vehicle
and check with your dealer.
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,

Seats and Restraints 3-43
The manufacturer's instructions that
come with the booster seat, state
the weight and height limitations for
that booster. Use a booster seat
with a lap-shoulder belt until the
child passes the below fit test:
.Sit all the way back on the seat.
Do the knees bend at the seat
edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt.
Does the shoulder belt rest on
the shoulder? If yes, continue.
If no, try using the rear safety
belt comfort guide. See“Rear
Safety Belt Comfort Guides”
under Lap-Shoulder Belt
on
page 3‑20for more information.
If the shoulder belt still does not
rest on the shoulder, then return
to the booster seat.
.Does the lap belt fit low and
snug on the hips, touching the
thighs? If yes, continue. If no,
return to the booster seat.
.Can proper safety belt fit be
maintained for the length of the
trip? If yes, continue. If no,
return to the booster seat.
Q: What is the proper way to wear safety belts?
A: An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder
belt can provide. The shoulder
belt should not cross the face or
neck. The lap belt should fit
snugly below the hips, just
touching the top of the thighs.
This applies belt force to the
child's pelvic bones in a crash.
It should never be worn over the
abdomen, which could cause
severe or even fatal internal
injuries in a crash. Also see
“Rear Safety Belt Comfort
Guides” underLap-Shoulder Belt
on
page 3‑20.
According to accident statistics,
children and infants are safer
when properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position.
In a crash, children who are not
buckled up can strike other people
who are buckled up, or can be
thrown out of the vehicle. Older
children need to use safety belts
properly.

Seats and Restraints 3-45
{WARNING
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Never leave children
unattended in a vehicle and never
allow children to play with the
safety belts.
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. Every
time infants and young children ride
in vehicles, they should have the
protection provided by appropriate
child restraints. Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.
{WARNING
Never do this.
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 should
be secured in an appropriate
restraint.

3-46 Seats and Restraints
{WARNING
Never do this.
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 right front
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 right front
seat, always move the front
passenger seat as far back as it
will go.
Q: What are the different types ofadd-on child restraints?
A: Add-on child restraints, which
are purchased by the vehicle's
owner, are available in four basic
types. Selection of a particular
restraint should take into
consideration not only the child's
weight, height, and age but also
whether or not the restraint will
be compatible with the motor
vehicle in which it will be used. For most basic types of child
restraints, there are many
different models available. When
purchasing a child restraint, be
sure it is designed to be used
in a motor vehicle. If it is, the
restraint will have a label saying
that it meets federal motor
vehicle safety standards.
The restraint manufacturer's
instructions that come with the
restraint state the weight and
height limitations for a particular
child restraint. In addition, there
are many kinds of restraints
available for children with
special needs.

Seats and Restraints 3-47
{WARNING
To reduce the risk of neck and
head injury during a crash,
infants need complete support.
This is because an infant's neck
is not fully developed and its head
weighs so much compared with
the rest of its body. In a crash,
an infant in a rear-facing child
restraint settles into the restraint,
so the crash forces can be
distributed across the strongest
part of an infant's body, the back
and shoulders. Infants should
always be secured in rear-facing
child restraints.
{WARNING
A young child's hip bones are still
so small that the vehicle's regular
safety 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, young children should
always be secured in appropriate
child restraints.
Child Restraint Systems
(A) Rear‐Facing Infant Seat
A rear-facing infant seat (A)
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.
