48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

As a guide, if you are shorter than average, you will prefer
the shoulder belt anchorage in a lower position, and if you
are taller than average, you will prefer the shoulder belt
anchorage in a higher position. After you release the
anchorage button, try to move it up or down to make sure
that it is locked in position.NOTE:
The adjustable upper shoulder belt anchorage is
equipped with an Easy Up feature. This feature allows the
shoulder belt anchorage to be adjusted in the upward
position without pushing or squeezing the release button.
To verify the shoulder belt anchorage is latched, pull
downward on the shoulder belt anchorage until it is locked
into position.
WARNING!
• Wearing your seat belt incorrectly could make your
injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.
• Position the shoulder belt across the shoulder and
chest with minimal, if any slack so that it is comfort-
able and not resting on your neck. The retractor will
withdraw any slack in the shoulder belt.

First Row Center Seat Belt Operating Instructions
(Regular Cab Only)
The first row center seat belt (Regular Cab only) features a
seat belt with a mini-latch plate and buckle, which allows
the seat belt to detach from the lower anchor when the seat
is folded. The latch plate and regular latch plate can then be
stored out of the way in the seat for added convenience to
open up utilization of the storage areas behind the front
seats when the seat is not occupied.
1. Remove the mini-latch plate and regular latch platefrom its stowed position on the seat.
2. Grasp the mini-latch plate and pull the seat belt over theseat.
3. Route the shoulder belt to the inside of the right head restraint.

the webbing is fully extended and the adjustable upper
shoulder belt anchorage (if equipped) is in its lowest
position, your authorized dealer can provide you with a
Seat Belt Extender. The Seat Belt Extender should be used
only if the existing seat belt is not long enough. When the
Seat Belt Extender is not required for a different occupant,
it must be removed.
WARNING!
• ONLY use a Seat Belt Extender if it is physically
required in order to properly fit the original seat belt
system. DO NOT USE the Seat Belt Extender if,
when worn, the distance between the front edge of
the Seat Belt Extender buckle and the center of the
occupant’s body is LESS than 6 inches.
• Using a Seat Belt Extender when not needed can
increase the risk of serious injury or death in a
collision. Only use the Seat Belt Extender when the
lap belt is not long enough and only use in the
recommended seating positions. Remove and store
the Seat Belt Extender when not needed.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Seat Belts And Pregnant Women
Seat belts must be worn by all occupants including preg-
nant 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 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 — If Equipped
This vehicle may be equipped with a seat belt system with
an Energy Management feature in the front seating posi-
tions 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 con-
trolled 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.

• ALR = Switchable Automatic Locking Retractor
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear aclick. 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 a vehicle with a rear seat.
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.
• Only use a rear-facing child restraint in 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.
WARNING!
• The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture 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 in-
crease 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.
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) moni-
tors the internal circuits and interconnecting wiring asso-
ciated 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
• Supplemental Side Air Bags
• Front and Side Impact Sensors — If Equipped
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Seat Belt Pretensioners
• Seat Belt Buckle Switch
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 Warn-
ing 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 diagnos-
tics 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.
