Properly Reclining the Safety Seat/Base
For your child’s safety, it is important that your safety seat/base be properly
reclined. Attached to the side of your safety seat is a level indicator to help
properly recline the safety seat/base on the vehicle seat.
Failure to properly recline the safety seat on the vehicle seat increases
the risk of serious injury or death.
If the safety seat is too upright, a child’s head may
drop forward and cause breathing problems.
If the safety seat is too reclined, a crash could put
too much force on a child’s neck and shoulders.
The safety seat must be properly reclined
according to the following instructions.
