WARNINGS
You should never use a booster
seat with only a lap belt.
Never put the shoulder belt
under a child s arm or behind
the back.
Never use pillows, books, or
towels to boost a child.
Children between 3½ and 12 years
and weighing between 15 and 36 kg
should use a booster cushion on the
rear seat. An adjustable auxiliary belt
fixed to the booster cushion ensures
optimum routing of the diagonal belt
over the shoulder. Make sure that
your child sits in an upright position.
