1-13 Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see ªSeatsº in the Index)
so you can sit up straight.
3. 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.
4. 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 isn't 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.

CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured or
killed. This is true even though your vehicle has
Next Generation frontal air bags. 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. To read how, see
the part of this manual called ªChildrenº and see
the caution labels on the sunvisors and the right
front passenger's safety belt.
There is an air bag readiness
light on the instrument
panel, which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.

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.

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. This is true even though your vehicle
has Next Generation frontal air bags. 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
CAUTION: (Continued)
CAUTION: (Continued)
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.
Secure the baby in an infant restraint.

A rear-facing infant restraint (B) positions an infant
to face the rear of the vehicle. Rear
-facing infant
restraints are designed for infants of up to about
20 lbs. (9 kg) and about one year of age. This type
of restraint faces the rear so that the infant's head,
neck and body can have the support they need in a
frontal crash. Some infant seats come in two
parts
-- the base stays secured in the vehicle and
the seat part is removable.
