button and remove the tongue from
the buckle.
Vehicle sensitive mode
Combination lap and shoulder belts in normal retractor mode allow free
shoulder belt length adjustment to your movements and locking in
response to vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle receives an impact of
approximately 5 mph (8 km/h) or more, the combination safety belts will
lock to help reduce forward movement of the driver and passengers.
Belt sensitive mode
Combination lap and shoulder belts can also be made to lock manually by
quickly pulling on the shoulder belt.
Automatic locking mode
When to use the automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.
This mode should be used any time a child safety seat (except a
booster) is installed in a passenger front or outboard rear seating
position (if equipped). Children 12 years old and under should be
properly restrained in the rear seat whenever possible. Refer to Safety
restraints for children or Safety seats for children later in this chapter.Seating and Safety Restraints

How to use the automatic locking mode
• Buckle the combination lap and
shoulder belt.
• Grasp the shoulder portion and
pull downward until the entire
belt is pulled out.
• Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
Disconnect 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: After any vehicle collision, the front passenger and
rear outboard safety belt systems must be checked by an
authorized dealer to verify that the “automatic locking retractor”
feature for child seats is still functioning properly. In addition, all safety
belts should be checked for proper function.Seating and Safety Restraints

WARNING: BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the safety belt assembly “automatic locking
retractor” feature or any other safety belt function is not operating
properly when checked by an authorized dealer. Failure to replace the
belt and retractor assembly could increase the risk of injury in
collisions.
Energy management feature
• This vehicle has a safety belt system with an energy management
feature at the front outboard seating positions to help further reduce
the risk of injury in the event of a head-on collision.
• The front outboard safety belt systems have a retractor assembly that
is designed to pay out webbing in a controlled manner. This feature is
designed to help reduce the belt force acting on the occupant’s chest.
Safety belt pretensioner
Your vehicle is equipped with safety belt retractor pretensioners at the
driver and front outboard passenger seating positions.
The driver and front outboard passenger safety belt pretensioners are
designed to activate only during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt pretensioner is a
device which tightens the webbing of the lap and shoulder belts during
some collisions in such a way that they fit more snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to the Child restraint and safety belt
maintenance section in this chapter.
WARNING: Failure to replace the safety belt assembly under
the above conditions could result in severe personal injuries in
the event of a collision.
Front safety belt height adjustment
The front outboard seating positions are equipped with safety belt height
adjusters.
Adjust the height of the shoulder belt so the belt rests across the middle
of your shoulder. Seating and Safety Restraints

WARNING: Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the seat belt
and increase the risk of injury in a collision.
To adjust the shoulder belt height,
push the button and slide the height
adjuster up or down. Release the
button and pull down on the height
adjuster to make sure it is locked in
place.
Safety belt with cinch tongue (Regular cab center seating position
and Super Cab/Crew Cab rear center seating positions)
The cinch tongue will slide up and down the belt webbing when the belt
is stowed or while putting safety belts on. When the lap/shoulder safety
belt is buckled, the cinch tongue will allow the lap portion to be
shortened, but pinches the webbing to keep the lap portion from getting
longer. The cinch tongue is designed to slip during a crash, so always
wear the shoulder belt properly and don’t allow any slack in either the
lap or shoulder portions.
Before you can reach and latch a combination lap and shoulder belt
having a cinch tongue into the buckle, you may have to lengthen the lap
belt portion of it.
1. To lengthen the lap belt, pull
some webbing out of the shoulder
belt retractor.
2. While holding the webbing below
the tongue, grasp the tip (metal
portion) of the tongue so that it is
parallel to the webbing and slide the
tongue upward.
3. Provide enough lap belt length so that the tongue can reach the
buckle.Seating and Safety Restraints

How to fasten the cinch tongue (Regular cab center seating
position and Super Cab/Crew Cab rear center seating positions)
1. Pull the combination lap and shoulder belt from the retractor so that
the shoulder belt portion of the safety belt crosses your shoulder and
chest.
2. Be sure the belt is not twisted. If the belt is twisted, remove the twist.
3. Insert the belt tongue into the proper buckle for your seating position
until you hear a snap and feel it latch.
4. Make sure the tongue is securely fastened to the buckle by pulling on
the tongue.
WARNING: The lap belt should fit snugly and as low as possible
around the hips, not across the waist.
While you are fastened in the safety belt, the combination lap/shoulder
belt with a cinch tongue adjusts to your movement. However, if you
brake hard, turn hard, or if your vehicle receives an impact of 5 mph
(8 km/h) or more, the safety belt will become locked and help reduce
your forward movement.

Insert the tongue into the correct
buckle (the buckle closest to the
direction the tongue is coming
from). To lengthen the belt, turn the
tongue at a right angle to the belt
and pull across your lap until it
reaches the buckle. To tighten the
belt, pull the loose end of the belt
through the tongue until it fits
snugly across the hips.
Shorten and fasten the belt when
not in use.

The following are reasons most often given for not wearing safety belts
(All statistics based on U.S. data):
Reasons given... Consider...
“Crashes are rare
events” 36700 crashes occur every day. The more we
drive, the more we are exposed to “rare” events,
even for good drivers. 1in4ofuswillbe
seriously injured in a crash during our lifetime.
“I’m not going far” 3of4 fatal crashes occur within 25 miles (40 km)
of home.
“Belts are
uncomfortable” We design our safety belts to enhance comfort. If
you are uncomfortable - try different positions for
the safety belt upper anchorage and seatback which
should be as upright as possible; this can improve
comfort.
“I was in a hurry” Prime time for an accident. Belt-Minder

reminds us to take a few seconds to buckle up.
“Safety belts don’t
work” Safety belts, when used properly, reduce risk of
death to front seat occupants by 45% in cars, and
by 60% in light trucks.
“Traffic is light” Nearly 1 of 2 deaths occur in single-vehicle
crashes, many when no other vehicles are around.
“Belts wrinkle my
clothes” Possibly, but a serious crash can do much more
than wrinkle your clothes, particularly if you are
unbelted.
“The people I’m
with don’t wear
belts” Set the example, teen deaths occur 4 times more
often in vehicles with TWO or MORE people.
Children and younger brothers/sisters imitate
behavior they see.
“I have an airbag” Airbags offer greater protection when used with
safety belts. Frontal airbags are not designed to
inflate in rear and side crashes or rollovers.
“I’d rather be
thrown clear” Not a good idea. People who are ejected are 40
times more likely to DIE. Safety belts help
prevent ejection, WE CAN’T “PICK OUR CRASH”.Seating and Safety Restraints
