You can add a small amount of slack. The system
works like a window shade. To add a little slack, pull
down on the shoulder belt just a little
-- no more
than 1 inch (25 mm).
If it's now too loose, pull it out like you did before
and start again.
If you move around in the vehicle and your shoulder
belt becomes loose, be sure to make it tight again.
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.

Q:What's wrong with this?
A:The shoulder belt is too loose. It won't give nearly
as much protection this way.
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. Don't
allow more than 1 inch (25 mm) of slack.

Q:What's wrong with this?
A:The belt is buckled in the wrong place.
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 at the pelvic
bones. This could cause serious internal injuries.
Always buckle your belt into the buckle
nearest you.

Q:What's 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 aren't as strong as shoulder bones.
You could also severely injure internal organs
like your liver or spleen.

Q:What's 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 wouldn't 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 to fix it.

Bench (A)Suspension (B)
To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way. For a
suspension
-type seat, if the belt is pulled out all the way
so that it locks, press down on the button on the retractor
cover to make it retract.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage both the
belt and your vehicle.

Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to be
seriously injured if they don't wear safety belts.
A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible, below
the rounding, throughout the pregnancy.The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Passenger Position
The right passenger's safety belt works the same way as
the driver's safety belt. See ªDriver Positionº earlier in
this section.

Center Passenger PositionLap Belt
If your vehicle has a full bench seat or a two-passenger
bench seat, someone can sit in the center position.
When you sit in a center seating position, you have a lap
safety belt, which has no retractor. To make the belt
longer, tilt the latch plate and pull it along the belt.

To make the belt shorter, pull its free end as shown until
the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap
-shoulder belt. 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.
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.

1-24 Smaller Children and Babies
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.
We know securing a child can present real problems in a
medium
-duty vehicle like yours. The only place where
you can properly secure a child restraint is the center
seating position, the place that has the lap belt only. But
your vehicle may not have a center seating position. Or,
even if you have one, you may find that the child
restraint keeps you from operating the shift lever or
other controls. The only answer may be to have the
smaller children make the trip in another vehicle, where
they can get the protection they need.
