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

properly. It also describes some
things not to do with safety belts.
{WARNING

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.

3-12 Seats and Restraints
{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.
