WARNING! The seat must not be used with a two-
point belt or a lap belt. When securing your child with
a two-point belt, this may result in injuries or death
of the child.
• Make sure that the carrying handle a is in the upper
position A (see page 10).
• Place the seat against driving position on the car
seat. (The feet of the baby point in the direction of the
backrest of the car seat).
• CYBEX ATON 3S can be used on all seats with a
three-point automatic retractor belt. We generally
recommend to use the seat in the back of the
vehicle. In the front, your child is usually exposed to
higher risks in case of an accident.
