WARNING!
• Failure to replace the seat belt assemblycould 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 har-
ness for restraining the child.
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 your autho-
rized 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
Air Bag Warning Light
The 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 immedi-
ately.

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.
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.
Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental
Side Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Cur-
tains (SABICs) are located above the side
windows. The trim covering the SABICs is
labeled “SRS AIRBAG” or “AIRBAG.” SABICs may help reduce the risk of head and
other injuries to front and rear seat outboard
occupants in certain side impacts, in addi-
tion 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 occu-
pants through side windows in certain side
impact events.
WARNING!
• Do not mount equipment, or stack lug-
gage or other cargo up high enough to
block the deployment of the SABICs.
The trim covering above the side win-
dows where the SABIC and its deploy-
ment path are located should remain
free from any obstructions.
• In order for the SABICs to work as in-
tended, do not install any accessory
items in your vehicle which could alter
the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof
racks that require permanent attach-
ments (bolts or screws) for installation

move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’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.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.
NOTE:
• Air bag covers may not be obvious in the interior 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 communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the batteryhas power or until the hazard light button is
pressed. The hazard lights can be deacti-
vated by pressing the hazard light button.
• Turn on the interior lights, which remain on as long as the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully 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.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.

will be installed as described here.
To Install A LATCH-Compatible Child Re-
straint
If the selected seating position has a Switch-
able Automatic Locking Retractor (ALR) seat
belt, stow the seat belt, following the instruc-
tions 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 an-
chorages for that seating position. For some
second row seats, you may need to recline
the seat and / or raise the head restraint 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.
3. Attach the lower hooks or connectors ofthe 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 Re-
straints 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 manufac-
turer’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 occu- pants 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 inter-
feres with the child restraint installation, in-
stead of buckling it behind the child re-
straint, 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. Un-
WARNING!
der 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 Ve-
hicle 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.
WARNING!
• Improper installation or failure to prop-erly 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 in-
fant or child restraint.
The seat belts in the passenger seating posi-
tions are equipped with either a Switchable
Automatic Locking Retractor (ALR) or a
cinching latch plate or both. Both types of
125

seat belts are designed to keep the lap por-
tion 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 “Auto-
matic Locking Mode” description in “Switch-
able Automatic Locking Retractors (ALR)”
under “Occupant Restraint Systems” for ad-
ditional 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.

Installing A Child Restraint With A Switch-
able 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.
WARNING!
• Improper installation or failure to prop-
erly 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 in-
fant or child restraint. 1.
For Crew, Mega, And Quad Cab Models
Place the child seat in the center of the
seating position. For some second row
seats, you may need to recline the seat
and/or raise the head restraint 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 posi-
tion to make room for the child seat. You
may also move the front seat forward to
allow more room for the child seat.
For Regular Cab Models
Place the child seat in the center of the
seating position. Move the vehicle seat as
far rearward as possible to keep the child
as far from the advanced passenger air
bag as possible. 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.
5. To lock the seat belt, pull down on the shoulder part of the belt until you have
pulled all the seat belt webbing out of the
retractor. Then, allow the webbing to re-
tract back into the retractor. As the web-
bing retracts, you will hear a clicking
sound. This means the seat belt is now in
the Automatic Locking mode.

6. Try to pull the webbing out of the retractor.If it is locked, you should not be able to
pull out any webbing. If the retractor is
not locked, repeat step 5.
7. Finally, pull up on any excess webbing to tighten the lap portion around the child
restraint while you push the child restraint
rearward and downward into the vehicle
seat.
8. If the child restraint has a top tether strap and the seating position has a top tether
anchorage, connect the tether strap to the

has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You
Should Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel bolts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
