Seat Belts And Pregnant Women

Seat Belts and Pregnant Women

Seat belts must be worn by all occupants
including pregnant women: the risk of injury in
the event of an accident is reduced for the
mother and the unborn child if they are wearing
a seat belt.
Position the lap belt snug and low below the
abdomen and across the strong bones of the
hips. Place the shoulder belt across the chest
and away from the neck. Never place the
shoulder belt behind the back or under the arm.
Seat Belt Pretensioner
The front outboard seat belt system is equipped
with pretensioning devices that are designed to
remove slack from the seat belt in the event of
a collision. These devices may improve the
performance of the seat belt by removing slack
from the seat belt early in a collision.
Pretensioners work for all size occupants,
including those in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The seat
belt still must be worn snugly and positioned
properly.
The pretensioners are triggered by the
Occupant Restraint Controller (ORC). Like the
air bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air bag
must be replaced immediately.
Energy Management Feature
The front outboard seat belt system is equipped
with an Energy Management feature that may
help further reduce the risk of injury in the event
of a collision. The seat belt system has a
retractor assembly that is designed to release
webbing in a controlled manner.
Switchable Automatic Locking Retractors
(ALR) — If Equipped
The seat belts in the passenger seating
positions may be equipped with a Switchable
Automatic Locking Retractor (ALR) which is
used to secure a child restraint system. For
additional information, refer to “Installing Child
Restraints Using The Vehicle Seat Belt” under
the “Child Restraints” section of this manual.
The figure below illustrates the locking feature
for each seating position.

Mega Cab/Crew Cab Automatic Locking Retractor (ALR) Locations

If the passenger seating position is equipped
with an ALR and is being used for normal usage,
only pull the seat belt webbing out far enough to
comfortably wrap around the occupant’s
mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound
as the seat belt retracts. Allow the webbing to
retract completely in this case and then
carefully pull out only the amount of webbing
necessary to comfortably wrap around the
occupant’s mid-section. Slide the latch plate
into the buckle until you hear a "click." In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still
retract to remove any slack in the shoulder belt.
Use the Automatic Locking Mode anytime a
child restraint is installed in a seating position
that has a seat belt with this feature. Children
12 years old and under should always be
properly restrained in the rear seat of a vehicle
with a rear seat.
How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder
belt.

2. Grasp the shoulder portion and pull downward until the entire seat belt is
extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound.
This indicates the seat belt is now in the
Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
ALR — Switchable Automatic Locking Retractor
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!
The seat belt assembly must be replaced if
the switchable Automatic Locking Retractor
(ALR) feature or any other seat belt function
is not working properly when checked
according to the procedures in the Service
Manual.

SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors — If Equipped
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch
is in the OFF position or in the ACC position, the
air bag system is not on and the air bags will not
inflate. The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the ignition
switch is first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first in the ON/RUN position.
Failure to replace the seat belt assembly
could increase the risk of injury in colli
-
sions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.

The SABs may help to reduce the risk of
occupant injury during certain side impacts, in
addition to the injury reduction potential
provided by the seat belts and body structure.
Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim cover.
The inflating SAB deploys through the seat
seam into the space between the occupant and
the door. The SAB moves at a very high speed
and with such a high force that it could injure
occupants if they are not seated properly, or if
items are positioned in the area where the SAB
inflates. Children are at an even greater risk of
injury from a deploying air bag. Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental
Side Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows.
The trim covering the SABICs is labeled “SRS
AIRBAG” or “AIRBAG.”

Supplemental Side Air Bag Inflatable Curtain (SABIC) Label Location
SABICs may help reduce the risk of head and
other injuries to front and rear seat outboard
occupants in certain side impacts, in addition to
the injury reduction potential provided by the
seat belts and body structure.
The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers
the window. The SABICs inflate with enough
force to injure occupants if they are not belted
and seated properly, or if items are positioned
in the area where the SABICs inflate. Children
are at an even greater risk of injury from a
deploying air bag.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants
through side windows in certain side impact
events.WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags;
the performance could be adversely affected
and/or objects could be pushed into you,
causing serious injury.
WARNING!
Do not mount equipment, or stack luggage
or other cargo up high enough to block the
deployment of the SABICs. The trim
covering above the side windows where the
SABIC and its deployment path are located
should remain free from any obstructions.

eye irritation, rinse the area with cool water.
For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If
these particles settle on your clothing, follow
the garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
NOTE:
Air bag covers may not be obvious in the inte -
rior trim, but they will open during air bag
deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event,
the Occupant Restraint Controller (ORC) will
determine whether to have the Enhanced
Accident Response System perform the
following functions:
Cut off fuel to the engine (if equipped)
Cut off battery power to the electric motor (if
equipped)
Flash hazard lights as long as the battery has
power
Turn on the interior lights, which remain on
as long as the battery has power or for
15 minutes from the intervention of the
Enhanced Accident Response System
Unlock the power door locks
Your vehicle may also be designed to perform
any of these other functions in response to the
Enhanced Accident Response System:
Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circula -
tion Door
Cut off battery power to the:
Engine
Electric Motor (if equipped)
Electric power steering
Brake booster
Electric park brake
Automatic transmission gear selector
Horn
Front wiper
Headlamp washer pump
NOTE:
After an accident, remember to cycle the igni -
tion to the STOP (OFF/LOCK) position and
remove the key from the ignition switch to avoid
draining the battery. Carefully check the vehicle
for fuel leaks in the engine compartment and on
the ground near the engine compartment and
fuel tank before resetting the system and
starting the engine. If there are no fuel leaks or
damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system
by following the procedure described below. If
you have any doubt, contact an authorized
dealer.
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as well.

some rear-facing child restraints will also be
equipped with a tether strap. The tether strap
will have a hook at the end to attach to the top
tether anchorage and a way to tighten the strap
after it is attached to the anchorage.
Center Seat LATCH
Regular Cab Or Crew Cab Full Bench Rear Seat:
No Lower Center LATCH Anchorages Available Crew Cab Split Bench Rear Seat Or Mega Cab
Rear Seat: Center LATCH Anchorages Available
If a child restraint installed in the center
position blocks the seat belt webbing or buckle
for the outboard position, do not use that
outboard position. If a child seat in the center
position blocks the outboard LATCH anchors or
seat belt, do not install a child seat in that
outboard position.
Always follow the directions of the child
restraint manufacturer when installing your
child restraint. Not all child restraint systems
will be installed as described here.
To Install A LATCH-Compatible Child
Restraint
If the selected seating position has a
Switchable Automatic Locking Retractor (ALR)
seat belt, stow the seat belt, following the
instructions below. See the section “Installing
Child Restraints Using the Vehicle Seat Belt” to
check what type of seat belt each seating
position has.

1. Loosen the adjusters on the lower straps
and on the tether strap of the child seat so
that you can more easily attach the hooks
or connectors to the vehicle anchorages.

2. Place the child seat between the lower anchorages for that 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.
WARNING!

Do not install a child restraint in the center
position using the LATCH system. This posi -
tion is not approved for installing child seats
using the LATCH attachments. You must use
the seat belt and tether anchor to install a
child seat in the center seating position.
Never use the same lower anchorage to
attach more than one child restraint. Please
refer to “To Install A LATCH-Compatible Child
Restraint” for typical installation instruc -
tions.

WARNING!
Never use the same lower anchorage to
attach more than one child restraint. Please
refer to “To Install A LATCH-Compatible Child
Restraint” for typical installation instructions.

3. Attach the lower hooks or connectors of the
child restraint to the lower anchorages in
the selected seating position.
4. If the child restraint has a tether strap, connect it to the top tether anchorage. See
the section “Installing Child Restraints
Using the Top Tether Anchorage” for
directions to attach a tether anchor.
5. Tighten all of the straps as you push the child restraint rearward and downward into
the seat. Remove slack in the straps
according to the child restraint
manufacturer’s instructions.
6. Test that the child restraint is installed tightly by pulling back and forth on the child
seat at the belt path. It should not move
more than 1 inch (25.4 mm) in any
direction.How To Stow An Unused Switchable-ALR
(ALR) Seat Belt:
When using the LATCH attaching system to
install a child restraint, stow all ALR seat belts
that are not being used by other occupants or
being used to secure child restraints. An unused
belt could injure a child if they play with it and
accidentally lock the seat belt retractor. Before
installing a child restraint using the LATCH
system, buckle the seat belt behind the child
restraint and out of the child’s reach. If the
buckled seat belt interferes with the child
restraint installation, instead of buckling it
behind the child restraint, route the seat belt
through the child restraint belt path and then
buckle it. Do not lock the seat belt. Remind all
children in the vehicle that the seat belts are not
toys and that they should not play with them.
WARNING!
Improper installation of a child restraint to
the LATCH anchorages 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.
Child restraint anchorages are designed to
withstand only those loads imposed by
correctly-fitted child restraints. Under no
circumstances are they to be used for adult
seat belts, harnesses, or for attaching other
items or equipment to the vehicle.

Installing Child Restraints Using The
Vehicle Seat Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the lap
belt portion of a lap/shoulder belt.
The seat belts in the passenger seating
positions are equipped with either a Switchable
Automatic Locking Retractor (ALR) or a cinching
latch plate or both. Both types of seat belts are
designed to keep the lap portion of the seat belt
tight around the child restraint so that it is not
necessary to use a locking clip. The ALR
retractor can be “switched” into a locked mode
by pulling all of the webbing out of the retractor
and then letting the webbing retract back into
the retractor. If it is locked, the ALR will make a
clicking noise while the webbing is pulled back into the retractor. Refer to the “Automatic
Locking Mode” description in “Switchable
Automatic Locking Retractors (ALR)” under
“Occupant Restraint Systems” for additional
information on ALR. The cinching latch plate is
designed to hold the lap portion of the seat belt
tight when webbing is pulled tight and straight
through a child restraint’s belt path.
Please see the table below and the following
sections for more information.
