Seats and Restraints 59
Reclining Seatbacks
{ WarningSitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job.
The shoulder belt 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 could go up over
your abdomen. The belt forces
would be there, not at your pelvic
bones. This could cause serious
internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly. Do not have a seatback reclined if
the vehicle is moving.

2. To recline, move the seatback
rearward to the desired

safety belts properly, and some
things not to do.
{ WarningDo 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
are more likely to be seriously
injured or killed. Do not allow
(Continued) Warning (Continued) 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 0 140 .

Belt Assurance System, which may
prevent the vehicle from shifting out

66 Seats and Restraints 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
safety belts. That is why wearing
safety belts makes such good
sense. Questions and Answers About
Safety Belts Q: Will I be trapped in the vehicle
after a crash if I am wearing a
safety belt?
A: You could be — whether you are
wearing a safety belt or not.
Your chance of being conscious
during and after a crash, so you
can unbuckle and get out, is
much greater if you are belted.
Q: If my vehicle has airbags, why
should I have to wear safety
belts?
A: Airbags are supplemental
systems only. 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.
Also, in nearly all states and in
all Canadian provinces, the law
requires wearing safety belts. How to Wear Safety Belts
Properly This section is only for people of
adult size.
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 0 87 or Infants and Young
Children 0 89 . 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.
