10. Test For Tightness
Grab the sides of the seat where the vehicle
seat belt is and slide the car seat side-to-
side and front-to-back.
If the seat moves less than 1" (2.5 cm), it is
tight enough.
11. Check the Level Indicator
Vehicle MUST be on level ground. Bubble
must be completely under the blue lines.
Readjust if needed.
For infants 3 months and under, the bubble
must completely be under the light blue
line.
If needed, rolled towels may be placed under
the car seat at the vehicle seat crease, until
the bubble is completely under the blue
lines.
See section 6 to secure your child.
Recheck level indicator with child in seat.
