4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.

6. To tighten the belt, feed the shoulder belt back
into the retractor while you push down on the child
restraint. You may find it helpful to use your knee
to push down on the child restraint as you tighten
the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle's
safety belt and let it go back all the way. The safety belt
will move freely again and be ready to work for an adult
or larger child passenger.

Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.
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 fit
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.

1-55
CAUTION:
Never do this.
Here two children are wearing the same belt. The
belt can't 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 seat next to a window,
move the child toward the center of the vehicle. If
the child is sitting in the center rear seat passenger
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. If the child is sitting in a rear seat
outside position, see ªRear Safety Belt Comfort
Guidesº in the Index.

1-56
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.

1-57
Safety Belt Extender
If the vehicle's safety belt will fasten around you,
you should use it.
But if a safety belt isn't long enough to fasten, your
dealer will order you an extender. It's free. When you go
in to order it, take the heaviest coat you will wear, so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don't let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach
it to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from
doing its job, 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.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
If you've had a crash, do you need new belts or LATCH
system parts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new parts.
If the LATCH system was being used during a more
severe crash, you may need new LATCH system parts.
If belts are cut or damaged, replace them. Collision
damage also may mean you will need to have LATCH
system, safety belt or seat parts repaired or replaced.
New parts and repairs may be necessary even if the belt
or LATCH system wasn't being used at the time of
the collision.
If an air bag inflates, you'll need to replace air bag
system parts. See the part on the air bag system earlier
in this section.

Windows
CAUTION:
Leaving children in a vehicle with the windows
closed is dangerous. A child can be overcome by
the extreme heat and can suffer permanent
injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with
the windows closed in warm or hot weather.
