Lap-Shoulder Belt (Extended Cab)
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted. The 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.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way, it
will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you'd be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should go
over the shoulder and across the chest. These parts of the
body are best able to take belt restraining forces.
The safety belt locks if there's a sudden stop or a crash.
The safety belt also locks if you pull the belt very
quickly out of the retractor.

CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward
too much, which could increase injury. The
shoulder belt should fit against your body.
To unlatch the belt, just push the button on the buckle.

Rear Safety Belt Comfort Guides for
Children and Small Adults
If your vehicle has a rear seat, your vehicle has shoulder
belt comfort guides. This feature will provide added
safety belt comfort for children who have outgrown
child restraints and for small adults. When installed on a
shoulder belt, the comfort guide pulls the belt away
from the neck and head.
There is one guide for each outside passenger position in
the rear seat. To provide added safety belt comfort for
children who have outgrown child restraints and for
smaller adults, the comfort guides may be installed on
the shoulder belts. Here's how to install a comfort guide
and use the safety 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.3. Be sure that the belt is not twisted and it lies flat.
The guide must be on top of the belt.

4. Buckle, position and release the safety belt as
described in ªRear Seat Passenger Positions
(Extended Cab)º earlier in this section. Make sure
that the shoulder belt crosses the shoulder.
To remove and store the comfort guides, squeeze the
belt edges together so that you can take them out from
the guides. Slide the guide onto the storage clip.
Children
Everyone in a vehicle needs protection! That includes
infants and all children smaller than adult size. 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.
Smaller Children and Babies
CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. Air bags plus lap
-shoulder belts offer
the best protection for adults, but not for young
children and infants. Neither the vehicle's safety
belt system nor its air bag system is designed for
them. Young children and infants need the
protection that a child restraint system can
provide. Always secure children properly in
your vehicle.

CAUTION:
Smaller children and babies should always be
restrained in a child or infant restraint. The
instructions for the restraint will say whether it is
the right type and size for your child. A very
young child's hip bones are so small that a
regular belt might not stay low on the hips, as it
should. Instead, the belt will likely be over the
child's abdomen. In a crash, the belt would apply
force right on the child's abdomen, which could
cause serious or fatal injuries. So, be sure that
any child small enough for one is always properly
restrained in a child or infant restraint.
Infants need complete support, including support for the
head and neck. This is necessary because an infant's
neck is weak and its head weighs so much compared
with the rest of its body. In a frontal crash, an infant in a
rear
-facing restraint settles into the restraint, so the crash
forces can be distributed across the strongest part of the
infant's body, the back and shoulders. A baby should be
secured in an appropriate infant restraint. This is so
important that many hospitals today won't release a
newborn infant to its parents unless there is an infant
restraint available for the baby's first trip in a
motor vehicle.

CAUTION:
Never hold a baby in your arms while riding in a
vehicle. A baby doesn't weigh much
-- until a
crash. During a crash a baby will become so
heavy you can't hold it. For example, in a crash
at only 25 mph (40 km/h), a 12
-lb. (5.5 kg) baby
will suddenly become a 240
-lb. (110 kg) force on
your arms. The baby would be almost impossible
to hold.
