* It is possible for a child to be classified as an adult, allowing a full-power Passenger Advanced Front Air Bag deployment. Never allow children to ride in the front passenger seat and
never install a child restraint system, including a rear-facing child restraint, in the front passenger seat.
The OCS determines the front passenger’s most
probable classification. The OCS estimates the
seated weight on the front passenger seat and
where that weight is located. The OCS
communicates the classification status to the
ORC. The ORC uses the classification to
determine whether the Passenger Advanced
Front Air Bag inflation rate should be adjusted.
In order for the OCS to operate as designed, it is
important for the front passenger to be seated
properly and properly wearing the seat belt.
Properly seated passengers are:
Sitting upright
Facing forward
Sitting in the center of the seat with their feet
comfortably on or near the floor
Sitting with their back against the seatback
and the seatback in an upright position

Seated Properly

Front Passenger Seat Occupant Status Front Passenger Air Bag Output
Rear-facing child restraint Reduced-power deployment
Child, including a child in a forward-facing child restraint or booster seat* Reduced-power deployment OR Full-power deployment
Properly seated adult Full-power deployment OR reduced-power deployment
Unoccupied seat Reduced-power deployment
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.
Children 12 years or younger should always
ride buckled up in the rear seat of a vehicle
with a rear seat.

SAFETY347
Lighter Weight Passengers (Including Small
Adults)
When a lighter weight passenger, including a
small adult, occupies the front passenger seat,
the OCS may reduce the inflation rate of the
Passenger Advanced Front Air Bag. This does
not mean that the OCS is working improperly.
Do not decrease OR increase the front
passenger’s seated weight on the front
passenger seat
The front passenger’s seated weight must be
properly positioned on the front passenger seat.
Failure to do so may result in serious injury or
death. The OCS determines the most probable
classification of the occupant that it detects.
The OCS will detect the front passenger’s
decreased or increased seated weight, which
may result in an adjusted inflation rate of the
Passenger Advanced Front Air Bag in a collision.
This does not mean that the OCS is working
improperly. Decreasing the front passenger’s
seated weight on the front passenger seat may
result in a reduced-power deployment of the
Passenger Advanced Front Air Bag. Increasing
the front passenger’s seated weight on the front
passenger seat may result in a full-power
deployment of the Passenger Advanced Front
Air Bag. Examples of improper front passenger seating
include:
The front passenger’s weight is transferred to
another part of the vehicle (like the door, arm
rest or instrument panel).
The front passenger leans forward, sideways,
or turns to face the rear of the vehicle.
The front passenger’s seatback is not in the
full upright position.
The front passenger carries or holds an
object while seated (e.g., backpack, box,
etc.).
Objects are lodged under the front passenger
seat.
Objects are lodged between the front
passenger seat and center console.
Accessories that may change the seated
weight on the front passenger seat are
attached to the front passenger seat.
Anything that may decrease or increase the
front passenger’s seated weight.
The OCS determines the front passenger’s most
probable classification. If an occupant in the
front passenger seat is seated improperly, the occupant may provide an output signal to the
OCS that is different from the occupant’s
properly seated weight input, for example:

The Air Bag Warning Light in the instrument
panel will turn on whenever the OCS is unable to
classify the front passenger seat status. A
malfunction in the OCS may affect the operation
of the air bag system.
If the Air Bag Warning Light does not come
on, or stays on after you start the vehicle, or it
comes on as you drive, take the vehicle to an
authorized dealer for service immediately.
The passenger seat assembly contains critical
OCS components that may affect the Passenger
Advanced Front Air Bag inflation. In order for the
OCS to properly classify the seated weight of a
front seat passenger, the OCS components
must function as designed. Do not make any
modifications to the front passenger seat
components, assembly, or to the seat cover. If
the seat, trim cover, or cushion needs service
WARNING!
If a child restraint system, child, small teen
-
ager or adult in the front passenger seat is
seated improperly, the occupant may
provide an output signal to the OCS that is
different from the occupant’s properly
seated weight input. This may result in
serious injury or death in a collision.
Always wear your seat belt and sit properly,
with the seatback in an upright position,
your back against the seatback, sitting
upright, facing forward, in the center of the
seat, with your feet comfortably on or near
the floor.
Do not carry or hold any objects (e.g., back -
packs, boxes, etc.) while seated in the front
passenger seat. Holding an object may
provide an output signal to the OCS that is
different than the occupant’s properly
seated weight input, which may result in
serious injury or death in a collision.
Placing an object on the floor under the
front passenger seat may prevent the OCS
from working properly, which may result in
serious injury or death in a collision. Do not
place any objects on the floor under the
front passenger seat.

Infant And Child Restraints
Safety experts recommend that children ride
rear-facing in the vehicle until they are two years
old or until they reach either the height or
weight limit of their rear-facing child restraint.
Two types of child restraints can be used
rear-facing: infant carriers and convertible child
seats.
The infant carrier is only used rear-facing in the
vehicle. It is recommended for children from
birth until they reach the weight or height limit of
the infant carrier. Convertible child seats can be
used either rear-facing or forward-facing in the
vehicle. Convertible child seats often have a
higher weight limit in the rear-facing direction
than infant carriers do, so they can be used
rear-facing by children who have outgrown their
infant carrier but are still less than at least two
years old. Children should remain rear-facing
until they reach the highest weight or height
allowed by their convertible child seat.
Older Children And Child Restraints
Children who are two years old or who have
outgrown their rear-facing convertible child seat
can ride forward-facing in the vehicle.
Forward-facing child seats and convertible child
seats used in the forward-facing direction are
for children who are over two years old or who
have outgrown the rear-facing weight or height
limit of their rear-facing convertible child seat.
Children should remain in a forward-facing child
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.
WARNING!
Do not install a rear-facing car seat using a
rear support leg in this vehicle. The floor of
this vehicle is not designed to manage the
crash forces of this type of car seat. In a
crash, the support leg may not function as it
was designed by the car seat manufacturer,
and your child may be more severely injured
as a result.

seat with a harness for as long as possible, up
to the highest weight or height allowed by the
child seat.
All children whose weight or height is above the
forward-facing limit for the child seat should use
a belt-positioning booster seat until the
vehicle’s seat belts fit properly. If the child
cannot sit with knees bent over the vehicle’s
seat cushion while the child’s back is against
the seatback, they should use a belt-positioning
booster seat. The child and belt-positioning
booster seat are held in the vehicle by the seat
belt.
Children Too Large For Booster Seats
Children who are large enough to wear the
shoulder belt comfortably, and whose legs are
long enough to bend over the front of the seat
when their back is against the seatback, should
use the seat belt in a rear seat. Use this simple
5-step test to decide whether the child can use
the vehicle’s seat belt alone:
1. Can the child sit all the way back against
the back of the vehicle seat?

2. Do the child’s knees bend comfortably over the front of the vehicle seat – while the child
is still sitting all the way back?
3. Does the shoulder belt cross the child’s shoulder between the neck and arm?
4. Is the lap part of the belt as low as possible, touching the child’s thighs and not the
stomach?
5. Can the child stay seated like this for the whole trip?
If the answer to any of these questions was
“no”, then the child still needs to use a booster
seat in this vehicle. If the child is using the lap/
shoulder belt, check seat belt fit periodically
and make sure the seat belt buckle is latched.
A child’s squirming or slouching can move the
belt out of position. If the shoulder belt contacts
the face or neck, move the child closer to the
center of the vehicle, or use a booster seat to
position the seat belt on the child correctly.
WARNING!
Improper installation can lead to failure of
an infant or child restraint. It could come
loose in a collision. The child could be badly
injured or killed. Follow the child restraint
manufacturer’s directions exactly when
installing an infant or child restraint.
After a child restraint is installed in the
vehicle, do not move the vehicle seat
forward or rearward because it can loosen
the child restraint attachments. Remove
the child restraint before adjusting the
vehicle seat position. When the vehicle seat
has been adjusted, reinstall the child
restraint.
When your child restraint is not in use,
secure it in the vehicle with the seat belt or
LATCH anchorages, or remove it from the
vehicle. Do not leave it loose in the vehicle.
In a sudden stop or accident, it could strike
the occupants or seatbacks and cause
serious personal injury.

Recommendations For Attaching Child Restraints
WARNING!
Never allow a child to put the shoulder belt under an arm or behind their back. In a crash, the shoulder belt will not protect a child properly, which
may result in serious injury or death. A child must always wear both the lap and shoulder portions of the seat belt correctly.

Frequently Asked Questions About Installing Child Restraints With LATCH
What is the weight limit (child’s weight + weight of the child
restraint) for using the LATCH anchorage system to attach
the child restraint? 65 lbs (29.5 kg)Use the LATCH anchorage system until the combined weight
of the child and the child restraint is 65 lbs (29.5 kg). Use
the seat belt and tether anchor instead of the LATCH system
once the combined weight is more than 65 lbs (29.5 kg).
Can the LATCH anchorages and the seat belt be used
together to attach a rear-facing or forward-facing child
restraint? NoDo not use the seat belt when you use the LATCH anchorage
system to attach a rear-facing or forward-facing child
restraint.
Booster seats may be attached to the LATCH anchorages if
allowed by the booster seat manufacturer. See your booster
seat owner’s manual for more information.
Can a child seat be installed in the center position using the
inner LATCH lower anchorages from the outboard seating
positions? NoQuad Cab or Crew with Full bench rear seat: Use the seat
belt and tether anchor to install a child seat in the center
seating position
Can two child restraints be attached using a common lower
LATCH anchorage? NoNever “share” a LATCH anchorage with two or more child
restraints. If the center position does not have dedicated
LATCH lower anchorages, use the seat belt to install a child
seat in the center position next to a child seat using the
LATCH anchorages in an outboard position.
Can the rear-facing child restraint touch the back of the front
passenger seat? YesThe child seat may touch the back of the front passenger
seat if the child restraint manufacturer also allows contact.
See your child restraint owner’s manual for more
information.
Can the rear head restraints be removed? No

Installing A Child Restraint With A
Switchable Automatic Locking Retractor
(ALR):
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
1. Place the child seat in the center of the
seating position. If the second row seat can
be reclined, you may recline the seat and/
or raise the head restraint (if adjustable) to
get a better fit. If the rear seat can be
moved forward and rearward in the
vehicle, you may wish to move it to its
rear-most position to make room for the child seat. You may also move the front
seat forward to allow more room for the
child seat.

2. Pull enough of the seat belt webbing from the retractor to pass it through the belt path
of the child restraint. Do not twist the belt
webbing in the belt path.
3. Slide the latch plate into the buckle until you hear a “click.”
4. Pull on the webbing to make the lap portion tight against the child seat.
Frequently Asked Questions About Installing Child Restraints With Seat Belts
What is the weight limit (child’s weight + weight of the child
restraint) for using the Tether Anchor with the seat belt to
attach a forward facing child restraint? Weight limit of the
Child Restraint Always use the tether anchor when using the seat belt to
install a forward facing child restraint, up to the
recommended weight limit of the child restraint.
Can the rear-facing child restraint touch the back of the front
passenger seat? YesContact between the front passenger seat and the child
restraint is allowed, if the child restraint manufacturer also
allows contact.
Can the rear head restraints be removed? No Head restraints may not be removed.
Can the buckle stalk be twisted to tighten the seat belt against
the belt path of the child restraint? NoDo not twist the buckle stalk in a seating position with an
ALR retractor.
WARNING!
Improper installation or failure to properly
secure a child restraint can lead to failure
of the restraint. The child could be badly
injured or killed.
Follow the child restraint manufacturer’s
directions exactly when installing an infant
or child restraint.
