Keep using a car booster seat until your child is about four feet nine inches tall. To see if the seat belt will fit your child, try the following test. *

1. Does the child sit all the way back against the auto seat?
   
2. Do the child's knees bend comfortably at the edge of the auto seat?
   
3. Does the lap belt fit snugly across the top of the thighs?
   
4. Does the shoulder part of the belt come across the center of the shoulder and chest?
5. Can the child sit like this for the whole trip?
