Safety Belts: They're for Everyone
This part
of
the manual
tells
you how
to
use safety belts properly. It also
tells you some things
you
should not do with safety belts.
And
it
explains the Supplemental Inflatable Restraint, or
"air
bag" system.
A
CAUTION:
Don't let anyoneride where heorshecan't wear
a
safety belt
properly.
If
you arein a crash and you're not wearing a safety
belt, your injuries can be much worse.You can hit things inside
the vehicle
or
be ejected from
it.
You
can be seriouslyinjured or
killed. Inthe samecrash, you might not beif you arebuckled
up. Alwaysfasten your safety belt,and check that your
passengers' belts arefastened properly too.
1-6

Your vehicle has
a
light that comes
on
as
a
reminder to buckle up. (See
“Safety Belt Reminder Light” in the Index.)
In
many states and Canadian provinces, the law says
to
wear safety belts.
Here’s why:
They
work.
You never know if you’ll be in
a
crash. If you do have a crash,
you
don’t
know
if
it
will be
a
bad one.
A
few crashes are mild,and some crashes canDe
so
serious that even
buckled up aperson wouldn’t survive. But most crashes arein between.
In
many of them, people whobuckle up can survive and sometimes walk away.
Without belts
they
could have been badly hurt or killed.
After more than
25
years of safety belts
in
vehicles, the facts areclear. In
most crashes bucklingup does matter
...
a lot!
Why
Safety
Belts
Work
When
you
ride in or on anything, you
go
as fast
as
i
t
goes.
Take
the
simplest
vehicle. Suppose it’s
just
a
seat
on
wheels.
1-7

Put someone
on
it.
Get
it
up to speed.
Then stop the vehicle.
The rider doesn't stop.
The person keeps
going
until
stopped
by
something.
In
a
real vehicle,
it
could be the
windshield
...
1-8

or the safety belts
!
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.
Here Are Questions Many People
Ask
About
Safety Belts
-
and
the Answers
Won’t
I
be trappedin the vehicle afteran 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,
soyou
can
unbuckle and get out,is
much
greater
if
you
are
belted.
1-9

0:
Why don ’t theyjust putin air bags
so
people won’t have
to
wear
A:
Air bags are in many vehicles today and will be in more 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 salehas required the use of safety belts. Even if you’re in a vehicle
that has airbags, you still have
to
buckle up to getthe most protection.
That’s true not
only
in frontal collisions, but especially in side and
other collisions.
safety belts?
Q
t
If
I’m a good driver, and
I
never drivefar fromhome, 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 asbad drivers.
Most accidents occurwithin
25
miles
(40
km) of home. And the
greatest number of serious injuries and deaths occurat speedsof less
than
40
mph
(65
km/h).
Safety belts are for everyone.
How
to Wear Safety Belts Properly
Adults
This part
is
only for people
of
adult size.
Be awarethat 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 the part
of
this manual called
“Children.” Follow those rules
for
everyone’s protection.
First, you’ll want
to
know which restraint systemsyour vehicle has.
We’ll start with the driver position.
