Rear-Facing Installations
It is important that the child seat be properly reclined.
Use the recline indicator on the child restraint to help
achieve an acceptable recline angle for rear-facing:

blue section.
Britax recommends a child with no head and neck
control be in the most reclined position.
NOTE: If necessary, the proper recline angle can be
achieved by placing a rolled towel or pool noodle
in the vehicle seat bight.

achieve an acceptable recline angle for forward facing:
