3-14 Seats and Restraints
.Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
If the vehicle is a regular cab, then
all seating positions in the vehicle
have a lap-shoulder belt. If the
vehicle is a double or crew 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
on page 3-19 for 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,
if equipped. See Passenger
Sensing System on page 3-30
for more information.

could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the

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.
Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants and
all other children. Neither the
distance traveled nor the age and
size of the traveler changes the
need, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all(Continued)
Warning (Continued)
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
Never leave children unattended
in a vehicle and never allow
children to play with the safety
belts.
Every time infants and young
children ride in vehicles, they should
have the protection provided by
appropriate child restraints. Neither
the vehicle's safety belt system nor
its airbag system is designed
for them.
Children who are not restrained
properly can strike other people,
or can be thrown out of the vehicle.

3-50 Seats and Restraints
{Warning
Do not attach more than one child
restraint to a single anchor,
except for the center top tether
anchors in the crew and double
cabs. Attaching more than one
child restraint to a single anchor
could cause the anchor or
attachment to come loose or even
break during a crash. A child or
others could be injured. To reduce
the risk of serious or fatal injuries
during a crash, attach only one
child restraint per anchor.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is

shoulder belt can tighten but
cannot be loosened if it is locked.

pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
and tighten the belt behind the
child restraint after the child
restraint has been installed.
{Caution
Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint on
page 3-43.
