What is the correct weight and height range for using the built-in child restraint in the Uplander?

The built-in child restraint should only be used with children who weigh between 22 and 40 lbs (10 and 18 kg) and whose height is between 33.5 and 40 inches (850 and 1,016 mm). The child must also be at least one year old, capable of sitting upright alone, and their shoulders must be below the shoulder belt slots for the harness system. Children who exceed these limits should use an appropriate add-on booster seat. (Page 85)
