Reclining Seatbacks
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen.
The belt forces would be
there, not at your pelvic bones.
This could cause serious
internal injuries.(Continued)

Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
Do not let anyone ride where
a safety belt cannot be worn
properly. In a crash, if you or
your passenger(s) are not
wearing safety belts, the injuries
can be much worse. You can hit
things inside the vehicle harder
or be ejected from the vehicle.
You and your passenger(s) can
be seriously injured or killed.
In the same crash, you might
not be, if you are buckled up.
Always fasten your safety belt,
and check that your passenger(s)
are restrained properly too.

{WARNING
People riding on the tailgate
(if equipped) can easily lose their
balance and fall even when the
vehicle is operated at low speeds.
Falling from a moving vehicle may
result in serious injuries or death.
{WARNING
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision, people
riding in these areas are more
likely to be seriously injured or
killed. Do not allow people to ride
in any area of your vehicle that
is not equipped with seats and
safety belts. Be sure everyone in
the vehicle is in a seat and using
a safety belt properly.This vehicle has indicators as a
reminder to buckle the safety belts.
See
Safety Belt Reminders on
page 5‑19 for additional information.
In most states and in all Canadian
provinces, the law requires wearing
safety belts. Here is why:
You never know if you will be in
a crash. If you do have a crash,
you do not know if it will be a
serious one.
A few crashes are mild, and some
crashes can be so serious that
even buckled up, a person would
not survive. But most crashes
are in between. In many of them,
people who buckle up can survive
and sometimes walk away. Without
safety belts they could have been
badly hurt or killed.
After more than 40 years of safety
belts in vehicles, the facts are clear.
In most crashes buckling up does
matter ... a lot!
Why Safety Belts Work
When you ride in or on anything,
you go as fast as it goes.
Take the simplest vehicle. Suppose
it is just a seat on wheels.

Put someone on it.Get it up to speed. Then stop the
vehicle. The rider does not stop.The person keeps going until
stopped by something. In a real
vehicle, it could be the windshield...

or the instrument panel...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 is why safety
belts make such good sense.
Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
safety belt?
A: You could be—whether you
are wearing a safety belt or
not. But your chance of being
conscious during and after an
accident, so you canunbuckle
and get out, is muchgreater if
you are belted. And you can
unbuckle a safety belt, even if
you are upside down.

Q: If my vehicle has airbags, whyshould I have to wear safety
belts?
A: Airbags are supplemental
systems only; so they work
with safety belts —not instead
of them. Whether or not an
airbag is provided, all occupants
still have to buckle up to get the
most protection. That is true not
only in frontal collisions, but
especially in side and other
collisions. Q: If I am 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 are in a crash —even
one that is not your fault —you
and your passenger(s) can be
hurt. Being a good driver does
not protect you from things
beyond your control, such
as bad drivers.
Most accidents occur within
40 km (25 miles) of home.
And the greatest number of
serious injuries and deaths
occur at speeds of less than
65 km/h (40 mph).
Safety belts are for everyone.How to Wear Safety Belts
Properly
This section 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
infants. If a child will be riding in
the vehicle, see Older Children on
page 3‑49 orInfants and Young
Children on page 3‑51. Follow those
rules for everyone's protection.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more
often in crashes than those who
are wearing safety belts.
Occupants who are not buckled up
can be thrown out of the vehicle in a
crash. And they can strike others in
the vehicle who are wearing safety
belts.
