Restraining a Child Who Weighs Over 40 Pounds (18 kg)
We recommend that, whenever possible, a child who has outgrown a
toddler seat ride in one of the outside positions of the rear seat and use
a lap/shoulder belt.
Put the lap/shoulder belt on your child and check its fit. The shoulder belt
should fit over the collarbone and across the chest. The lap belt should
sit low on your child's hips, not across the stomach.
If the shoulder belt crosses the neck, have your child move toward the
center of the rear seat until the belt fits properly. If the belt still crosses
the child's neck, you should use a booster seat.
Several styles of booster seats are available. We recommend a design
that allows the child to use the car's lap/shoulder belt.
Whichever style you select, follow the booster seat manufacturer's
instructions.
