Seat Belts And Pregnant Women
Pregnant Women And Seat Belts
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 — If Equipped
3500 Models Only
The front outboard seat belt system may be 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 place -
ment 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. 4

Energy Management Feature — If Equipped
3500 Models Only
The front outboard seat belt system may be 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. Regular Cab Automatic Locking Retractor (ALR) Locations ALR = Switchable Automatic Locking Retractor

SAFETY 201
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 automati -
cally 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.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. 4

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. Supplemental Restraint Systems (SRS)
Some of the safety features described in this section may be stan -
dard 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 — If Equipped
• Front and Side Impact Sensors — If Equipped

• The seat belt assembly must be replaced if the switch -
able 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.
• Failure to replace the seat belt assembly could increase
the risk of injury in collisions.
• 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.

SAFETY 203
Air Bag Warning Light
The ORC monitors the readiness of the elec -
tronic 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 posi -
tion 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 instru -
ment 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.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine related gauges
are not working, the Occupant Restraint Controller (ORC)
may also be disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an authorized
dealer service the air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on as
a bulb check when the ignition is first turned on, stays
on after you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the air bag
system immediately. 4

204 SAFETY
Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are a
supplement to the seat belt restraint systems. The driver
front air bag is mounted in the center of the steering wheel.
The passenger front air bag is mounted in the instrument
panel, above the glove compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on the air bag covers.
Front Air Bag/Knee Bolster Locations1 — Driver And Passenger Front Air Bags
2 — Driver And Passenger Knee Impact Bolsters WARNING!
• Being too close to the steering wheel or instrument
panel during front air bag deployment could cause
serious injury, including death. Air bags need room to
inflate. Sit back, comfortably extending your arms to
reach the steering wheel or instrument panel.
• 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.

SAFETY 205
(Continued)Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter -
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Advanced
Front Air Bags. Front Air Bag Operation
Front Air Bags are designed to provide additional protection
by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or rollover
collisions. The front air bags will not deploy in all frontal
collisions, including some that may produce substantial
vehicle damage — for example, some pole collisions, truck
underrides, and angle offset collisions.WARNING!
• No objects should be placed over or near the air bag on
the instrument panel or steering wheel because any
such objects could cause harm if the vehicle is in a colli -
sion severe enough to cause the air bag to inflate. • Do not put anything on or around the air bag covers or
attempt to open them manually. You may damage the
air bags and you could be injured because the air bags
may no longer be functional. The protective covers for
the air bag cushions are designed to open only when
the air bags are inflating.
• Relying on the air bags alone could lead to more severe
injuries in a collision. The air bags work with your seat
belt to restrain you properly. In some collisions, air
bags won’t deploy at all. Always wear your seat belts
even though you have air bags. WARNING! (Continued)

206 SAFETY
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not good
indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away from
an inflating air bag.
When the ORC detects a collision requiring the front air bags,
it signals the inflator units. A large quantity of non-toxic gas
is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper passenger
side of the instrument panel separate and fold out of the way
as the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The front
air bags then quickly deflate while helping to restrain the
driver and front passenger. Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the driver
and front passenger, and position the front occupants for
improved interaction with the front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs) — If
Equipped
Your vehicle may be equipped with Supplemental
Seat-Mounted Side Air Bags (SABs). If your vehicle is
equipped with Supplemental Seat-Mounted Side Air Bags
(SABs), please refer to the information below. WARNING!
• Do not drill, cut, or tamper with the knee impact
bolsters in any way.
