5. Tighten the
Vehicle Seat Belt
Lay your forearm
across the car seat
at the belt path and
push down. Pull on the
shoulder belt to tighten
while feeding the slack
back in the retractor.
6. Test For Tightness
Grab the sides of the
car seat where the seat
belt is and push and
pull the car seat from
side to side and front to
back.
If the car seat moves
less than 2.5 cm (1 in),
it is tight enough.
