{WARNING
You can be seriously hurt if your
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
your 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 your belt
into the buckle nearest you.

2-16 Seats and Restraints
Q: What is wrong with this?
A:The belt is over an armrest.
{WARNING
You can be seriously injured if
your 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.

Seats and Restraints 2-17
{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.

2-18 Seats and Restraints
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/retailer 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.
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.

Seats and Restraints 2-19
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 2‑23.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary. 4. 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.
5. 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. For outboard seating
positions, 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.
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 that the
shoulder portion of the belt is
centered on the shoulder. The belt
should be away from the face and
neck, but not falling off the shoulder.
Improper shoulder belt height
adjustment could reduce the
effectiveness of the safety belt in
a crash.
Move the height adjuster up to the
desired position by pushing up on
the height adjuster.
After the height adjuster is set to the
desired position, try to move it up or
down without pressing the release
button (A) to make sure it has
locked into position. Press the
release button to lower the height
adjuster.
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, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. And, if the
vehicle has side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
they need to be replaced, and other
new parts for the vehicle's safety
belt system may be required. See
Replacing Safety Belt System Parts
After a Crash on page 2‑24.

Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they are
available through your dealer/
retailer. 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
seatback.
2. Place the guide over the belt,and insert the two edges of the
belt into the slots of the guide.

2-22 Seats and Restraints
3. The belt should not be twistedand it should lie 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 that the shoulder belt
crosses the shoulder.
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Slide
the guide back into its storage
pocket located on the side of the
seatback.

Seats and Restraints 2-23
Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer/retailer will
order you an extender. When you
go in to order it, take the heaviest
coat you will wear, so the extender
will be long enough for you. To help
avoid personal injury, do not let
someone else use it, and use it
only for the seat it is made to fit.
The extender has been designed for
adults. Never use it for securing
child seats. To wear it, attach it to
the regular safety belt. For more
information, see the instruction
sheet that comes with the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors and
anchorages are working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer/
retailer to have it repaired. Torn or
frayed safety belts may not protect
you in a crash. They can rip apart
under impact forces. If a belt is torn
or frayed, get a new one right away.

2-24 Seats and Restraints
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders
on page 4‑14for more
information.
Keep safety belts clean and dry.
See Safety Belt Care
on
page 2‑24.
Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Replacing Safety Belt
System Parts After a
Crash
{WARNING
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in a
crash. To help make sure the
safety belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible. After a minor crash, replacement of
safety belts may not be necessary.
But the safety belt assemblies that
were used during any crash may
have been stressed or damaged.
See your dealer/retailer to have the
safety belt assemblies inspected or
replaced.
New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. See
Airbag
Readiness Light on page 4‑15.
