Q:If I am a good driver, and I never drive far
from home, why should I wear safety
belts?
A:You may be an excellent driver, but if you are
in an accident — even one that is not your
fault — you and your passengers can be hurt.
Being a good driver does not protect you
from things beyond your control, such as bad
drivers.
Most accidents occur within 25 miles (40 km)
of home. And the greatest number of
serious injuries and deaths occur at speeds of
less than 40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part 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 babies.
If a child will be riding in your vehicle, see
Older Children on page 61orInfants and Young
Children on page 64. Follow those rules for
everyone’s protection.
First, you will want to know which restraint
systems your vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to
wear it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight.
To see how, see “Seats” in the Index.

Page 56 of 608
The safety belt locks if there is a sudden stop or a
crash, or if you pull the belt very quickly out of
the retractor.
{CAUTION:
You can be seriously hurt if your shoulder
belt is too loose. In a crash, you would
move forward too much, which could
increase injury. The shoulder belt should
t against your body.
To unlatch the belt, push the button on the buckle.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide
added safety belt comfort for older children
who have outgrown booster seats and for some
adults. When installed on a shoulder belt, the
comfort guide positions the belt away from
the neck and head.

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are located on the retractor
part of the safety belts. They help the safety
belts reduce a person’s forward movement in a
moderate to severe frontal, near frontal, rear
or side crash, or a rollover.
Pretensioners work only once. If they activate
in a crash, you will need to get new ones,
and probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 109.
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
t. The extender has been designed for adults.
Never use it for securing child seats. To wear it,
just attach it to the regular safety belt. For
more information see the instruction sheet that
comes with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats
should wear the vehicle’s safety belts.
If you have the choice, a child should sit in a seat
that has a lap-shoulder belt and get the additional
restraint a shoulder belt can provide.
Q:What is the proper way to wear safety
belts?
A:If possible, an older child should wear a
lap-shoulder belt and get the additional
restraint a shoulder belt can provide. The
shoulder belt should not cross the face
or neck. The lap belt should t snugly below
the hips, just touching the top of the thighs. It
should never be worn over the abdomen,
which could cause severe or even fatal internal
injuries in a crash.
Accident statistics show that children are safer if
they are restrained in the rear seat.
In a crash, children who are not buckled up can
strike other people who are buckled up, or can be
thrown out of the vehicle. Older children need
to use safety belts properly.

{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt can not properly spread the
impact forces. In a crash, the two children
can be crushed together and seriously
injured. A belt must be used by only
one person at a time.
Q:What if a child is wearing a lap-shoulder
belt, but the child is so small that the
shoulder belt is very close to the child’s
face or neck?
A:If the child is sitting in a rear seat outside
position, move the child toward the center
of the vehicle. If the child is sitting in the
second row center position, move the child
toward the safety belt buckle. In either
case, be sure that the shoulder belt still is on
the child’s shoulder, so that in a crash the
child’s upper body would have the restraint
that belts provide. SeeRear Safety Belt
Comfort Guides on page 56. If the child is
so small that the shoulder belt is still very close
to the child’s face or neck, you might want
to place the child in a rear seat that has a lap
belt, if your vehicle has one.

{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the
belt in this way, in a crash the child might
slide under the belt. The belt’s force
would then be applied right on the child’s
abdomen. That could cause serious or
fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just
touching the child’s thighs. This applies belt force
to the child’s pelvic bones in a crash.
