How to Wear Safety Belts
Properly
This section is only for people of
adult size.
Be aware that 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 3‑42or Infants and Young
Childrenon page 3‑44. 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. 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.

2. Pick up the latch plate and pullthe 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.
Engaging the child restraint
locking feature in the right front
seating position may affect the
passenger sensing system. See
Passenger Sensing System
on
page 3‑35for more information.
3. Push the latch plate into the buckle 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 3‑26.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

Seats and Restraints 3-23
To move it down, press the release
button (A) and move the height
adjuster to the desired position.
You can move the height adjuster
up just 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 button to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for the 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, for vehicles
with side impact airbags, safety belt
pretensioners can help tighten the
safety belts in a side crash or a
rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle's safety belt system. See
Replacing Safety Belt System Parts
After a Crash on page 3‑27.
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 shoulder belt away
from the neck and head.

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. 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
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 5‑9for more
information.
Keep safety belts clean and dry.
See Safety Belt Care
on
page 3‑26.
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.
