3-10 Seats and Restraints
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, injuries can be much
worse than if you are wearing
safety belts. You can be seriously
injured or killed by hitting things
inside the vehicle harder or by
being ejected from the vehicle. In
addition, anyone who is not
buckled up can strike other
passengers in the vehicle.
It is extremely dangerous to ride
in a cargo area, inside or outside
of a vehicle. In a collision,
passengers riding in these areas(Continued)
Warning (Continued)
are more likely to be seriously
injured or killed. Do not allow
passengers to ride in any area of
the vehicle that is not equipped
with seats and safety belts.
Always wear a safety belt, and
check that all passenger(s) are
restrained properly too.
This vehicle has indicators as a
reminder to buckle the safety belts.
See Safety Belt Reminders on
page 5-15.
This vehicle may have the Safety
Belt Assurance System, which may
prevent the vehicle from shifting out
of P (Park). See Safety Belt
Messages on page 5-37.
Why Safety Belts Work
When riding in a vehicle, you travel
as fast as the vehicle does. If the
vehicle stops suddenly, you keep
going until something stops you.
It could be the windshield, the
instrument panel, or the safety belts!
When you wear a safety belt, you
and the vehicle slow down together.
There is more time to stop because
you stop over a longer distance and,
when worn properly, your strongest
bones take the forces from the
