Your child’s height, weight, and age determine how the car seat should
be placed in the vehicle.
Children vary widely in body size, shape, and temperament—please
consult your doctor before switching between any modes within
the limits and fit requirements of the car seat.
Infants and Toddlers
Must use the seat in rear-facing mode as long as possible, which is
until the child reaches the maximum weight or height limit for rear-
facing mode.
Toddlers and Preschoolers
Once they are facing forward, the child must use the seat in forward-
facing mode with a harness for as long as possible, which is until the
child reaches the maximum weight or height limit for forward-facing
mode.
School-Aged Children
Once they have outgrown their forward-facing car seat, the child must
use a belt-positioning booster seat until the vehicle’s lap and shoulder
seat belt fit properly.
If you have any questions regarding the proper mode for your child,
please see the back cover of this manual for our contact information.
