10. Test For Tightness
Grab the sides of the seat where the UAS
strap is and slide the car seat side-to-side
and front-to-back.
If the seat moves less than 2.5 cm (1 in), it
is tight enough.
11. Check the Level Indicator
Vehicle MUST be on level ground.
Check the level indicator on the car seat.
The bubble must be completely within
the blue zone. Readjust if needed.
See section 6-A to secure your child.
Recheck the level indicator with child in
seat.
