3-20 Seats and Restraints
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.
First, before you or your
passenger(s) wear a safety belt,
there is important information you
should know.
Sit up straight and always keep
your feet on the floor in front of you.
The lap part of the belt should beworn low and snug on the hips,
just touching the thighs. In a crash,
this applies force to the strong
pelvic bones and you would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on your abdomen.
This could cause serious or even
fatal injuries. The shoulder belt
should go over the shoulder and
across the chest. These parts of
the body are best able to take belt
restraining forces.
The shoulder belt locks if there is a
sudden stop or crash.
Q: What is wrong with this?
A:
The shoulder belt is too
loose. It will not give as
much protection this way.

Seats and Restraints 3-21
{WARNING
You can be seriously hurt if the
shoulder belt is too loose. In a
crash, you would move forward
too much, which could increase
injury. The shoulder belt should fit
snugly against your body.Q: What is wrong with this?
A:
The lap belt is too loose.
It will not give nearly as much
protection this way.
{WARNING
You can be seriously hurt if the
lap belt is too loose. In a crash,
you could slide under the lap
belt and apply force on your
abdomen. This could cause
serious or even fatal injuries.
The lap belt should be worn
low and snug on the hips, just
touching the thighs.

3-22 Seats and Restraints
Q: What is wrong with this?
A:The belt is buckled in the wrong
buckle.
{WARNING
You can be seriously injured if
the belt is buckled in the wrong
place like this. In a crash, the belt
would go up over your abdomen.
The belt forces would be there,
not on the pelvic bones. This
could cause serious internal
injuries. Always buckle the belt
into the buckle nearest you. Q: What is wrong with this?
A:
The belt is over an armrest.

Seats and Restraints 3-23
{WARNING
You can be seriously injured if
the belt goes over an armrest like
this. The belt would be much too
high. In a crash, you can slide
under the belt. The belt force
would then be applied on the
abdomen, not on the pelvic
bones, and that could cause
serious or fatal injuries. Be sure
the belt goes under the armrests.Q: What is wrong with this?
A:
The shoulder belt is worn under
the arm. It should be worn over
the shoulder at all times.
{WARNING
You can be seriously injured
if you wear the shoulder belt
under your arm. In a crash,
your body would move too far
forward, which would increase the
chance of head and neck injury.
Also, the belt would apply too
much force to the ribs, which are
not as strong as shoulder bones.
You could also severely injure
internal organs like your liver or
spleen. The shoulder belt should
go over the shoulder and across
the chest.

3-24 Seats and Restraints
Q: What is wrong with this?
A:The belt is behind the body.
{WARNING
You can be seriously injured by
not wearing the lap-shoulder
belt properly. In a crash, you
would not be restrained by the
shoulder belt. Your body could
move too far forward increasing
the chance of head and neck
injury. You might also slide
under the lap belt. The belt
force would then be applied right
on the abdomen. That could
cause serious or fatal injuries.
The shoulder belt should go
over the shoulder and across
the chest. Q: What is wrong with this?
A:
The belt is twisted across
the body.

Seats and Restraints 3-25
{WARNING
You can be seriously injured by a
twisted belt. In a crash, you would
not have the full width of the belt
to spread impact forces. If a belt
is twisted, make it straight so it
can work properly, or ask your
dealer to fix it.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
If you are using a rear seating
position with a detachable safety
belt and the safety belt is not
attached, see“Returning the
Seat to the Seating Position” under
Third Row Seats on page 3‑13
for instruction on reconnecting
the safety belt to the mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.

3-26 Seats and Restraints
If the shoulder portion of a
passenger belt is pulled out
all the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into thebuckle until it clicks. 4. Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑31.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
5. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you.
See “Shoulder Belt Height
Adjuster” later in this section
for instructions on use and
important safety information.
6. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull
the stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.

Seats and Restraints 3-27
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position. Slide
the latch plate up the safety belt
webbing when the safety belt is not
in use. The latch plate should rest
on the stitching on the safety belt,
near the guide loop on the side wall.
Before a door is closed, be sure
the safety belt is out of the way.
If a door is slammed against a
safety belt, damage can occur to
both the safety belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger seating
positions.
Adjust the height so the shoulder
portion of the belt is on the
shoulder but not falling off of it.
The belt should be close to but
not contacting the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. SeeHow
to Wear Safety Belts Properly on
page 3‑19.
To move it down, push down on
the release button (A) and move
the height adjuster to the desired
position. You can move the height
adjuster up by pushing up on the
shoulder belt guide.
After the adjuster is set to the
desired position, try to move it down
without pushing the release button
to make sure it has locked into
position.
