Q:What is wrong with this?
A:The belt is buckled in the wrong buckle.
{CAUTION:
You can be seriously injured if your belt is buckled
in the wrong place like this. In a crash, the belt
would go up over your abdomen. The belt forces
would be there, not on the pelvic bones. This
could cause serious internal injuries. Always
buckle your belt into the buckle nearest you.

Q:What is wrong with this?
A:The belt is over an armrest.
{CAUTION:
You can be seriously injured if your belt goes over
an armrest like this. The belt would be much too
high. In a crash, you can slide under the belt. The
belt force would then be applied on the abdomen,
not on the pelvic bones, and that could cause
serious or fatal injuries. Be sure the belt goes
under the armrests.

Q:What is wrong with this?
A:The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
{CAUTION:
You can be seriously injured if you wear the
shoulder belt under your arm. In a crash, your
body would move too far forward, which would
increase the chance of head and neck injury. Also,
the belt would apply too much force to the ribs,
which are not as strong as shoulder bones. You
could also severely injure internal organs like your
liver or spleen. The shoulder belt should go over
the shoulder and across the chest.

Q:What is wrong with this?
A:The belt is behind the body.
{CAUTION:
You can be seriously injured by not wearing the
lap-shoulder belt properly. In a crash, you would
not be restrained by the shoulder belt. Your body
could move too far forward increasing the chance
of head and neck injury. You might also slide
under the lap belt. The belt force would then be
applied right on the abdomen. That could cause
serious or fatal injuries. The shoulder belt should
go over the shoulder and across the chest.

Q:What is wrong with this?
A:The belt is twisted across the body.
{CAUTION:
You can be seriously injured by a twisted belt. In a
crash, you would not have the full width of the belt
to spread impact forces. If a belt is twisted, make
it straight so it can work properly, or ask your
dealer/retailer to x it.

Lap-Shoulder Belt
If your vehicle is a regular cab, then all seating positions
in the vehicle have a lap-shoulder belt. If your vehicle is a
crew or extended cab, then all seating positions in the
vehicle have a lap-shoulder belt except for the center
front passenger position (if equipped), which has a lap
belt. SeeLap Belt (Crew and Extended Cab) on
page 1-36for more information.
The following instructions explain how to wear a
lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can
sit up straight. To see how, see “Seats” in the Index.
2. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt across
you more slowly.
If the shoulder portion of a passenger belt is pulled
out all the way, the child restraint locking feature may
be engaged. If this happens, let the belt go back all
the way and start again.Engaging the child restraint locking feature may
affect the passenger sensing system. SeePassenger
Sensing System on page 1-84for more information.
If the belt stops before it reaches the buckle, when
using the lap-shoulder belt in a rear center seating
position of a crew-cab, tilt the latch plate and keep
pulling the safety belt until it can be buckled.

3. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-37.
If the latch plate will not go fully into the buckle,
check if the correct buckle is being used.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. See
“Shoulder Belt Height Adjustment” later in this
section.5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the lap belt
on smaller occupants.

To unlatch the belt, push the button on the buckle.
The belt should return to its stowed position.
Before a door is closed, be sure the safety belt is out
of the way. If a door is slammed against a safety belt,
damage can occur to both the safety belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
To move the adjuster
down for the regular and
crew cabs, squeeze the
buttons (A) on the sides of
the height adjuster and
move the height adjuster
to the desired position.
Regular and Crew Cab

On the extended cab, push
down on the release
button (A) and move the
height adjuster to the
desired position.
You can move the adjuster up just by pushing up on the
shoulder belt guide.
After you move the adjuster to where you want it, try to
move it down, without squeezing the buttons for the
regular and crew cabs, or without pushing the release
button for extended cabs, to make sure it has locked into
position.Safety Belt Pretensioners
This vehicle has safety belt pretensioners for
front outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the safety
belt assembly. They can help tighten the safety belts
during the early stages of a moderate to severe frontal,
near frontal, or rear crash if the threshold conditions for
pretensioner activation are met. And, if your vehicle has
side impact airbags, safety belt pretensioners can help
tighten the safety belts in a side crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle’s safety
belt system. SeeReplacing Restraint System Parts

Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.
There is one guide for each outboard passenger position
in the rear seat. Here is how to install a comfort guide to
the shoulder belt:
1. Remove the guide from its storage clip on the
interior body.
2. Place the guide over the belt and insert the two
edges of the belt into the slots of the guide.
