Seats and Restraints The manufacturer's instructions that come with the booster seat, state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the below fit test: . . 3-47 Does the lap belt fit low and snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat. Can proper safety belt fit be maintained for the length of the trip? If yes, continue. If no, return to the booster seat. . This applies belt force to the child's pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash. Also see "Rear Safety Belt Comfort Guides" under Lap-Shoulder Belt on page 3‑25. According to accident statistics, children and infants are safer when properly restrained in a child restraint system or infant restraint system secured in a rear seating position. Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat. Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear safety belt comfort guide. See "Rear Safety Belt Comfort Guides" under Lap-Shoulder Belt on page 3‑25 for more information. If the shoulder belt still does not rest on the shoulder, then return to the booster seat. Q: What is the proper way to wear safety belts? A: An older child should wear a lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. .
