The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-28.
The right front passenger’s safety belt works the same
way as the driver’s safety belt—except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature
which may turn off the passenger’s frontal air bag. If this
happens unintentionally, just let the belt go back all
the way and start again.
Center Passenger Position
If your vehicle has front and rear bench seats, someone
can sit in the center positions.
When you sit in the center seating position in the
second row you have a lap-shoulder belt which is similar
to the rear outside seating positions. To learn how to
wear this belt see“Lap-Shoulder Belt”underRear Seat
Passengers on page 1-38.

Rear Safety Belt Comfort Guides for
Children and Small Adults
Your vehicle may have this feature already. If it doesn’t,
you can get it from any GM dealer.
Rear shoulder belt comfort guides will provide added
safety belt comfort for older children who have outgrown
booster seats and for small adults. When installed on
a shoulder belt, the comfort guide better positions
the belt away from the neck and head.
There is one guide available for each outside passenger
position in the rear seat. Here’s how to install a
comfort guide and use the safety belt:
1. For the second row, remove the guide from its
storage clip on the trim panel near the side of
the seatback.
For the third row, remove the guide from its storage
clip 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.

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
shouldfit 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’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 rear seat outside position,
move the child toward the center of the vehicle. See
Rear Safety Belt Comfort Guides for Children and
Small Adults on page 1-41. 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. 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 a 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.
Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.

For most basic types of child restraints, there are
many different models available. When purchasing a
child restraint, be sure it is designed to be used
in a motor vehicle. If it is, the restraint will have a
label saying that it meets federal motor vehicle
safety standards.
The restraint manufacturer’s instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
{CAUTION:
Newborn infants need complete support,
including support for the head and neck. This is
necessary because a newborn infant’s neck is
weak and its head weighs so much compared
with the rest of its body. In a crash, an infant in a
rear-facing seat settles into the restraint, so the
crash forces can be distributed across the
strongest part of an infant’s body, the back and
shoulders. Infants always should be secured in
appropriate infant restraints.
{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain lowon the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that’s
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.

Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuousflat
surface. Make sure that the infant’s head rests toward
the center of the vehicle.A rear-facing infant seat (B) provides restraint with the
seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.A booster seat (F-G) is a child restraint designed to
improve thefit of the vehicle’s safety belt system. Some
booster seats have a shoulder belt positioner, and
some high-back booster seats have afive-point harness.
A booster seat can also help a child to see out the
window.
