When choosing a child restraint, be sure the child
restraint is designed to be used in a vehicle. If it is, it
will have a label saying that it meets federal motor
vehicle safety standards.
Then follow the instructions for the restraint. You may
find these instructions on the restraint itself or in a
booklet, or both. These restraints use the belt system in
your vehicle, but the child also has to be secured within
the restraint to help reduce the chance of personal injury.
The instructions that come with the infant or child
restraint will show you how to do that. Both the owner's
manual and the child restraint instructions are important,
so if either one of these is not available, obtain a
replacement copy from the manufacturer.
Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat. We at
General Motors therefore recommend that you put your
child restraint in a rear seat outside position. Never put a
rear
-facing child restraint in the front passenger seat.
Here's why:
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates, even though your
vehicle has Next Generation frontal air bags. This
is because the back of the rear
-facing child
restraint would be very close to the inflating air
bag. Always secure a rear
-facing child restraint
in a rear seat outside position.
You may secure a forward-facing child restraint
in the right front seat, but before you do, always
move the front passenger seat as far back as it
will go. It's better to secure the child restraint in
a rear seat outside position.
Wherever you install it, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people in
the vehicle. Be sure to properly secure any child
restraint in your vehicle
-- even when no child is in it.

1-43 Top Strap
Canadian law requires that forward-facing child
restraints have a top strap, and that the strap
be anchored.
If your child restraint has a top strap, it should be
anchored. Anchor brackets for the rear outside seat
positions are located on the floor in the cargo area.
Don't use the front set of tie-down brackets. Anchor the
top strap to the rearmost bracket on the same side of the
vehicle as the child restraint.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself.

1-44 Securing a Child Restraint in a Rear
Outside Seat Position
You'll be using the lap-shoulder belt. See the earlier part
about the top strap if the child restraint has one. Be sure
to follow the instructions that came with the child
restraint. Secure the child in the child restraint when and
as the instructions say.
1. Put the restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front of the child's face or
neck, put it behind the child restraint.
3. 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.

4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.5. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you're using a forward
-facing child
restraint, you may find it helpful to use your knee
to push down on the child restraint as you tighten
the belt.
6. 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.
Center Seat Position
Don't use child restraints in this position. The restraints
won't work properly.
Securing a Child Restraint in the Right
Front Seat Position
Your vehicle has a right front passenger air bag. Never
put a rear

Larger Children
Children who have outgrown child restraints should
wear the vehicle's safety belts.
If you have the choice, a child should sit next to a
window so the child can wear a lap
-shoulder belt and
get the additional restraint a shoulder belt can provide.
