Seating and Safety Restraints When children should use booster seats Children need to use booster seats from the time they outgrow the toddler seat until they are big enough for the vehicle seat and lap/shoulder belt to fit properly. Generally this is when they weigh about 80 lb. (36 kg) (about 8 to 12 years old). Booster seats should be used until you can answer YES to ALL of these questions: • Can the child sit all the way back against the vehicle seat back with knees bent comfortably at the edge of the seat without slouching? • Does the lap belt rest low across the hips? • Is the shoulder belt centered on the shoulder and chest? • Can the child stay seated like this for the whole trip? Types of booster seats There are two types of belt-positioning booster seats: • Those that are backless. If your backless booster seat has a removable shield, remove the shield and use the lap/shoulder belt. If a seating position has a low seat back and no head restraint, a backless booster seat may place your child's head (top of ear level) above the top of the seat. In this case, move the backless booster to another seating position with a higher seat back and lap/shoulder belts. 220 2006 Navigator (nav) Owners Guide (post-2002-fmt) USA (fus)
