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, seeOlder
Children on page 3‑32 orInfants
and Young Children on page 3‑34.
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.
There are important things to know
about wearing a safety belt properly.
.Sit up straight and always keep
your feet on the floor in front
of you.
.Always use the correct buckle
for your seating position.
.Wear the lap part of the belt 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.
.Wear the shoulder belt 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.
{WARNING
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.

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.
SeeReplacing Safety Belt System
Parts after a Crash on page 3‑19.
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 is nottwisted 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
(Continued)
WARNING (Continued)
and across the chest. These parts
of the body are best able to take
belt restraining forces.
4. Buckle, position, and release thesafety 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.
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 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. 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 all 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
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.
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders on page 5‑13.
Keep safety belts clean and dry.
See Safety Belt Care on page 3‑18.
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 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 5‑14.
Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the driver.
.A frontal airbag for the front
outboard passenger.
.A seat-mounted side impact
airbag for the driver.
.A seat-mounted side impact
airbag for the front outboard
passenger.
.A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
.A roof-rail airbag for the front
outboard passenger and the
passenger seated directly
behind the front outboard
passenger.
The vehicle may have the following
airbags:
.Seat-mounted side impact
airbags for the second row
outboard passengers.

What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover. The inflator, the airbag,
and related hardware are all part of
the airbag module.
For airbag location, seeWhere Are
the Airbags? on page 3‑21.
How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact
the inside of the vehicle. Airbags supplement the protection
provided by safety belts by
distributing the force of the impact
more evenly over the
occupant's body.
But airbags would not help in many
types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? on
page 3‑23.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they inflate. Some components of
the airbag module may be hot for several minutes. For location of the
airbags, see
Where Are the
Airbags? on page 3‑21.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
