Safety Belts
Safety Belts: They Are
for Everyone
This section of the manual describes
how to use safety belts properly.
It also describes some things not to
do with safety belts.
{CAUTION
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.
{CAUTION
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
your vehicle is in a seat and using
a safety belt properly.
{CAUTION
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.This vehicle has indicators as a
reminder to buckle the safety belts.
SeeSafety Belt Reminders on
page 3-24.
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!
