{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.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.
{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.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.
{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.
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.

Seats and Restraints 3-23
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.
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 3‑27. Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
If equipped with a shoulder
belt height adjuster, move it
to the height that is right for
you. See
“Shoulder Belt Height
Adjustment” later in this section
for instructions on use and
important safety information.
4. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
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 and 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 3‑17.
Press the release button (A) and
move the height adjuster to the
desired position. The adjuster
can be moved up by pushing the
slide/trim up. 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.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety
belt pretensioners cannot be seen,
they are part of the safety belt
assembly. They can help tighten
the safety belts during the early
stages of a moderate to severe
frontal and near frontal crash if
the threshold conditions for
pretensioner activation are met.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.
See Replacing Safety Belt System
Parts After a Crash on page 3‑28.

Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they
are available through your dealer.
The guides may provide added
safety belt comfort for older children
who have outgrown booster seats
and for some adults. When installed
and properly adjusted, the comfort
guide positions the belt away from
the neck and head.There is one guide for each outside
passenger position in the rear seat.
Here is how to install a comfort
guide to the safety belt:
1. Remove the guide from its
storage pocket on the side of
the seat.
2. Place the guide over the belt,and insert the two edges of the
belt into the slots of the guide.

3. Be sure that the belt isnot twisted and it lies flat.
The elastic cord must be under
the belt and the guide on top.
{WARNING
A safety belt that is not properly
worn may not provide the
protection needed in a crash.
The person wearing the belt could
be seriously injured. 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.
4. Buckle, position, and releasethe safety belt as described
previously in this section. Make
sure the shoulder portion of the
belt is on the shoulder and not
falling off of it. The belt should
be close to, but not contacting,
the neck.
