people
who buckle up can survive and sometimes walk as it goes-
away. Without belts they could have been badly hurt or killed.
After more than
30 years of safety belts in vehicles, the
facts are clear. In most crashes buckling up does
matter
... a lot!
Take the simplest vehicle. Suppose it's just a seat

With safety belts, you slow down as the vehicle does.
You get more time
to stop. You stop over more distance,
and your strongest bones take the forces. That’s why
safety belts make such good sense.
Questions and Answers About
Safety Belts
Q: Won’t I be trapped in the vehicle after an
accident
if I’m wearing a safety belt?
A: You could be - whether you’re wearing a safety
belt
or not. But you can unbuckle a safety belt,
even
if you’re upside down. And your chance
of being conscious during and after an accident,
so
you can unbuckle and get out, is much greater if
you are belted.
Q: If my vehicle has air bags, why should I have to
wear safety belts?
A: Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only;
so they work with
safety belts - not instead of them. Every air bag
system ever offered for sale has required the use
of
safety belts. Even if you’re in a vehicle that has
air bags, you still have
to buckle up to get the most
protection. That’s true not only in frontal collisions,
but especially in side and other collisions.

Q: If I’m a good driver, and I never drive far from
home,
why should I wear safety belts?
A: You may be an excellent driver, but if you’re in an
accident
- even one that isn’t your fault - you and
your passengers can be hurt. Being a good driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within
25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies.
If a child will be
riding in your vehicle, see Older Children
on page 7-48
or lnfants and Young Children on page 1-50. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.

Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door. 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 Safety Belt
Extender on page 1-47.
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.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.

5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt. 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? 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.
A: The shoulder belt is too loose. It won’t give nearly
as much protection this way.
